What to Expect When Having an AC Unit Installed

Written by Kevin on August 5, 2021. Posted in HVAC.

Having an air conditioner put in is a surprisingly involved process. Far from being a simple, do-it-yourself project, these efforts require careful calculations, skilled labor to ensure that a building’s electrical wiring and ductwork accommodate new equipment and more. Whether you’re having your very first air conditioner installed or you’re replacing an existing cooling system, knowing exactly what to expect can make everything far less daunting.

Having Your Old Air Conditioner Swapped Out

The average life span of an air conditioner is about 12 to 15 years. In some homes, existing cooling equipment is much older than this. Although AC equipment tends to become progressively less efficient after the 10-year mark, many homeowners are content to leave their aging systems in place so long as they continue working. This means that there are often dramatic differences in the size of existing cooling equipment and any air conditioner that’s brand-new. AC manufacturers are designing and producing cooling units with far larger cooling coils. These upgrades make modern air conditioners both more efficient and far more effective. They also make new air conditioners much bigger overall. Because of this, replacing an outdated air conditioner isn’t as simple as pulling the old unit out and popping the new one in. Many of the features that support this equipment will have to be adapted to accommodate recent innovations. Everything from the ductwork throughout the home to the existing wiring will likely need modification.

Just as cooling equipment evolves, the local building codes pertaining to this equipment may have changed as well. Indoor compressors and outside condensers might have new requirements for clearances that require building or landscaping adjustments. Thus, even though you already have air conditioning, expect your HVAC installer to devise a multi-pronged plan for your air conditioner installation. Moreover, expect this plan to be significantly more involved than simply removing and replacing what you already have.

What If a Home Has Never Had Air Conditioning Before?

For homes that have never had air conditioning, the options for putting an air conditioner in may be a bit more limited. This is certainly the case for buildings that don’t have existing ductwork. Installing HVAC ductwork post-construction can be a costly endeavor. It can also cut significantly into the amount of livable area that people have in their homes, and it can definitely be a bit of an eyesore. The good news is that lacking ductwork doesn’t mean that you’re stuck with inefficient window AC units, fans or swamp coolers. If you’re located in or near Hanover, bring your project to Beltway Air Conditioning and Heating. We provide custom ductwork for buildings that lack ducting, and our post-construction projects are affordable, aesthetically pleasing and designed for maximum space conservation.

There’s also the option of having a multi-split air conditioner installed. Multi-split air conditioning systems can efficiently deliver cooling all throughout the home. Best of all, these systems offer zone-by-zone cooling so that building residents can create their preferred temperatures all throughout the property.

Ductless mini-split air conditioners are also a great choice for homes that already have central air conditioning but also have areas or rooms that aren’t being serviced by this equipment. For instance, if you’ve recently finished and renovated your basement or attic or if you’ve added an in-law unit, you can use ductless air conditioning to service these spaces and to add to the value and appeal of your house. Ductless mini-splits are also great for cooling down garages, workshops and other separate buildings on the property.

What It’s Like to Have a Ductless Mini-Split Air Conditioner Put In?

Installing a ductless mini-split in any home that lacks ductwork is often a fairly swift and seamless process. When needed, these systems can also include ductless heat pumps so that homeowners have the benefit of household-wide heating as well. Ductless mini-split air conditioners have two primary components. These are an outside condenser or compressor and an indoor air handler. Depending upon how many zones or rooms must be serviced, you may need multiple air handlers. With an individual air handler in each zone or room, the temperature in each area can be customized according to individual resident needs. These installations also include a drain line, suction and refrigerant tubing and a condensate drain. More often than not, HVAC technicians won’t need to make any significant modifications to the actual building apart from cutting a single, small-sized hole in the exterior wall. Moreover, the air handlers that are used for air distribution are flat and relatively inconspicuous. They can even be installed on the ceiling or upper wall so that room aesthetics aren’t greatly impacted.

The Installation and Calibration of Your New Thermostat

With new central cooling equipment, you’ll need to have a new thermostat put in. Central HVAC systems can be zoned to provide the same customized cooling that ductless multi-splits can. With this arrangement, a separate thermostat will be installed in each heating and cooling zone. A new thermostat will give you the opportunity to upgrade to a programmable, smart design for improved energy management and the ability to control the HVAC system remotely. If your thermostat was in a less-than-ideal location before, such as by an oven or clothes dryer or in an area that gets lots of natural light, a new and better location will be chosen.

Every newly installed thermostat will be calibrated and tested. After this final task is complete, your provider will clean up all of the resulting project debris. This includes the removal and disposal of old cooling equipment and any waste created by modifications to the electrical system, ductwork or exterior walls.

Learning How to Use Your New Air Conditioner and Thermostat

Reputable HVAC companies don’t just recommend the most needs-specific and budget-friendly models for their clients and put the system in. They also show consumers how to operate their new equipment. After paying for an air conditioner that’s far more efficient than your last one and gaining access to a variety of innovative AC functions and features, you’ll definitely want to know how to use them. Your technician will take the time to walk you through all of the different phases and types of AC operation. You’ll learn how to:

Turn the air conditioner off and on.
Toggle between fan and cooling modes.
Program your thermostat.
Connect your thermostat to the mobile devices of your choosing.
Leverage the zoning capabilities of your new system, if applicable.
Reset the circuit breaker to turn your AC on after a power outage.
Perform filter changes and other basic maintenance.

By the time your HVAC technician leaves, you should feel completely confident in using your air conditioner and in performing all recommended forms of preventative maintenance. You’ll also have your owner’s manuals for all of your newly installed equipment, and you can always call your installer with any equipment-related questions.

Air Conditioner Problems You May Face This Summer

Written by Kevin on July 27, 2021. Posted in HVAC.

You depend on your air conditioner to keep you safe and comfortable during the summer. However, it is when the heat and humidity are at their worst that these systems tend to break down. Here are the common issues you may face as the weather continues heating up.

Low Airflow

The first thing you are likely to notice is less air coming from your output vents. This indicates an airflow restriction somewhere in your system. The first place to check for a restriction is at your air filter, which you should replace about every 90 days.

However, there are many other airflow restrictions your system may experience. Tiny particles make it past the filter and settle farther in your system. This settlement occurs commonly at the evaporator coil and heat exchanger.

Particles also build up on the circulating fan and further within your ductwork. Routine professional maintenance is the best option for preventing most of these airflow restrictions from forming.

You may also experience a freeze in your system. If your evaporator coil freezes, it prevents air from flowing properly through the coil.

Frozen System

Your air conditioner works by transferring heat from inside your home to the air outside through the refrigerant. In order to make this happen, your system must regulate the up and down refrigerant pressure.

Refrigerant gets cold when the pressure drops, which is what cools the air in your system. However, if the refrigerant’s pressure drops when it shouldn’t, or it drops too much, it causes the system to freeze.

A refrigerant leak is the most common cause of a drop in refrigerant pressure and a freeze occurring within the system. A leak inside your home, such as at the evaporator coil, also poses a health hazard.

In addition to a refrigerant leak, an airflow restriction may cause the system to freeze. When your air filter clogs, it prevents enough air from flowing into your HVAC system. This means the refrigerant cannot absorb the right amount of heat, leaving it too cold.

Contaminants collecting on the evaporator coil can also lead to system freezes. These create a type of insulation on the coils, which prevents heat transference as well. These contaminants also absorb moisture, compounding the freeze when it happens.

Tripped Circuit Breaker

Your air conditioner should not trip the breaker under normal circumstances. However, as the heat outside intensifies, your breaker may trip.

Typically, when the breaker trips, it means there is a problem with the air conditioner’s compressor. This is the component that raises the refrigerant pressure before it enters the condensing coil. The compressor is already the largest draw of electricity in the system.

There are many issues that may cause your compressor to strain, leading it to draw more electricity. One of the primary issues being the low refrigerant in the system.

In addition to low refrigerant, problems within the compressor may cause it to strain. If you have a damaged compressor, you are likely looking at a new one, which is a very costly repair. Depending on the age of your system, you may want to look at a system replacement.

Outside of the compressor, there are seven other problems that may cause your breaker to trip. A substantial airflow restriction could cause the breaker to trip, though this is not as common. Additionally, your breaker may trip because of a loose wire or electrical connection, condensing fan motor malfunction, or power surges.

If your circuit breaker trips, you should have a professional get at the cause. Ignoring it and continuing to push the breaker back on can cause substantial damage to your system. It may also pose a significant safety risk, leading to an electrical fire.

Warm Air From Your Vents

When you turn your air conditioner on, you expect to get cool air coming from your vents. However, when the system isn’t running correctly, you may notice warm and humid air coming through it instead.

The first question would be if there is enough refrigerant in the system. Without the right amount of refrigerant, the entire system doesn’t pressurize properly. This means that when it flows into the evaporator coil, there is no pressure drop, so it doesn’t get cold.

The next question is when was the last time your system had professional maintenance? If it has been more than a year, it may be a dirty evaporator coil preventing proper cooling.

Next, what is the condition of your outside condensing unit? If it cannot draw enough air in through the condensing coil, the refrigerant will retain too much heat. This prevents it from getting as cold as it should, reducing overall cooling.

Debris around your condensing unit and damage to the condensing coil can inhibit proper airflow. Ideally, keep at least 12 inches of clearance around and above your unit to ensure air can move properly.

Another common restriction is weeds growing up around the condensing unit. Be careful using a power trimmer around your unit as these can easily damage the coils.

Loud Sounds

Sounds from your air conditioner can tell you a lot about what is happening inside. While sounds themselves may not be a problem, they certainly tell you a problem is happening and can help you avoid a catastrophic failure.

A common sound you may hear is a loud buzzing, especially if your system is getting older. This usually indicates an electrical problem with one of your components. The usual suspects for a buzzing sound are the capacitor or one of the fan motors going bad.

You may also hear a rattling sound from your unit, especially if it hasn’t had maintenance recently. This is caused by components loosening as the system runs, including the condensing fan cage or the fan blades.

Chattering is a very distinct sound you will hear when the condensing contactor goes bad. This component acts as the switch to start the compressor at the start of the cooling cycle.

Your fan motors may give off a loud squealing sound when they are going bad. Oftentimes, this squealing is the result of the fan bearings going bad, which is preventable when they are lubricated regularly.

Banging and clanking sounds should also draw your awareness. This typically means something has broken loose and is bouncing around. The compressor is the most common location for these parts to break loose.

Creeping Energy Consumption

Whether you experience any other symptoms, keep an eye on your energy bill. If you notice your energy consumption is continually climbing, even during mild weather, you know you have a problem. This consumption is how you determine efficiency, so if you consume more, your system is operating less efficiently.

Airflow restrictions are the most common cause of efficiency degradation. Be sure to change your filters regularly and have your system maintained annually.

Additionally, low refrigerant or wearing components lead to efficiency problems. The goal of annual maintenance is to keep your system running at peak efficiency and catch small problems early.

Effective Ways of Quieting a Noisy Air Conditioner

Written by Kevin on July 12, 2021. Posted in HVAC.

An air conditioner is an excellent addition to your home. During winter or summer, an AC will be your lifesaver. Depending on when you had your air conditioning system installed, the components of your AC might start to fail due to age. In addition, moving parts may run out of lubrication and develop some noise when running. Typically, a noisy air conditioner will cause you more comfort than it will comfort you.

This might cause you to feel frustrated and even contemplate selling or scrapping the entire unit. However, instead of pulling the plug on your air conditioner, you can try a few tricks to quieten the air conditioner. This is always a great idea, especially since replacing the whole air conditioner could be very expensive. In this article, we get to give you a few tips that will help you maintain the quiet around your home.

Here we will cover the following air conditioners:

Outdoor air conditioner
Indoor air conditioner
Window air conditioner

1. Quieting a Window Air Conditioning System

Typically, if your window air conditioner produces some noise, the probable causes are the spaces and openings around the unit. Your provider might have left gaps and holes around the window air conditioner when installing the air conditioner. When the window air conditioning system is running, the fans and the compressor tend to vibrate. The air conditioner’s gaps accentuate this vibration, and then the solid material makes the AC transfer the noise to your house.

To fix this problem, you can attempt to seal the openings and spaces around the AC. Essentially, you will be blocking off the noise from the air conditioner and keeping your house free of external noise. How do I seal the spaces? Well, to seal the cracks and openings, you can use sealing materials such as insulation foam. You evaluate the air conditioner frame for openings and then add the insulation material. Insulation foam is an excellent choice for this particular job. All you have to do is get an insulation foam of about two to three inches in thickness and place it in the openings.

One reason insulation foam is a great choice is the fact that it can be easily installed. In addition, removing it is easier and does not require any expert knowledge. Apart from insulation foam, you can also use acrylic material. This material should also be of similar measurements. You get to place the air conditioner squarely against the space available with an acrylic sheet. This prevents your air conditioner from moving and also absorbs any noise produced from the AC’s vibrations. With new technology, new types of acrylic have been made available. These sheets are fixed with internal tubing that absorbs and blocks noise from your air conditioner.

Other Ways of Quietening Your Air Conditioner

Check for loose fittings and fasten them accordingly.
Ensure that your air conditioner sits squarely on the frame.
Fasten back the loose screws.
Straighten the fan blades.
Check for debris in the air conditioner fan.
Lubricate the fan’s motor to alleviate the screeching sounds.
Remove the dust that could have settled on the coil fins.

2. Quieting a Noisy Indoor AC

When the noise comes from your indoor air conditioning unit, you will have the worst experience. Essentially, your working or living environment will be the opposite or peaceful. When your indoor air conditioner is the source of noise, then you might consider getting a professional to check your blower fan motor. This motor is majorly responsible for collecting the warm air inside your home and sending it to the outdoor unit for cooling.

In addition, the motor ensures that cool air can be circulated inside your home. Though the blower is always the main suspect, you can also get your indoor air conditioner checked for a faulty switching process in the compressor. A faulty switching involves continuous turning on and off that produces noisy switching sounds. To counter this problem, you can use mass-loaded vinyl – popularly known as MLV⁠—to soundproof your living or working space. An MLV is placed against the walls to insulate against sound entry. The following are other methods through which you can minimize noise from an indoor air conditioner.

Change the location of the air conditioner.
Prevent echo by installing the air conditioner away from vents and air ducts.
Get a professional to fix the air conditioner.
Reduce the impact of the noise by placing the AC away from usable spaces.
Fasten any loose fittings.

3. Quieting a Noisy Outdoor Air Conditioner

With a noisy outdoor air conditioning unit, you risk getting sued for noise disturbance. Simply put, a noisy outdoor air conditioner is not a problem only for you. Therefore, you should consider fixing the noisy outdoor unit for your comfort and peace as soon as possible. In this particular case, the most probable culprit is always the unit compressor. In other situations, a disfigured fan is the problem. Mainly, most noise problems emanating from an outdoor unit are caused by either electrical or structural issues. Some of these causes are:

A faulty compressor that produces noise during operation
Capacitor and wiring problems – cause buzzing sounds
Bent rotor blades on the fans – responsible for banging noises
Leaking AC fluid (refrigerant) – causes a hissing noise
Poor-fitting of the air conditioner unit on its frame

To fix these problems, you will need to contact a professional. Attempting to fix the electrical issues can be dangerous for you and the air conditioner.

4. What Are the Other Ways of Quieting a Noisy Air Conditioner?

Apart from the above methods, you can reduce the noise from your air conditioner through simple tricks easily achievable using locally available material. In essence, you will be soundproofing your air conditioner to ensure that noise does not escape. The following are the additional methods.

Use a Soundproofing Blanket

Fixing most of the new generation air conditioners is quite a cakewalk, especially if there are no internal components involved. However, with old air conditioners, the materials and structure of the AC cannot do much to protect you from the noise. Old models did not employ much padding to handle compressor and fan vibrations. Since this is simply a structural problem and not an electrical problem, you can use a blanket to muffle the noise. It is an easily implementable option.

Use Noise Barriers

If you have tried all the options and nothing works, then a noise barrier will do the trick. Though it could be considered overkill, a noise barrier ensures that the noise produced by the AC remains at the AC.

Use an Air Conditioning Fence

If you have surrounded your AC with a noise barrier, installing an AC fence will be pretty easy. Simply add soundproofing material to the noise barrier, and you won’t have to worry about noise again.

Noise could be a discomfort in the same way that sweltering heat is. For this reason, you should try to minimize the noise that is coming from your AC as soon as possible. If nothing works, calling an expert is a great option.

How Does Central Air Conditioning Work?

Written by Kevin on June 15, 2021. Posted in HVAC.

Most homeowners rely on their central air conditioning unit to provide cool air during the scorching hot summer months. However, many of them don’t quite understand how their air conditioning system works. Although it’s ingenious, it’s actually not terribly complex, and it shouldn’t be a mystery. We’re going to go over all of the air conditioning system’s components below and explain how they function in unison to provide you with home comfort during the summer season.

The Components of Your AC System

Every centralized home air conditioning system has a few key components that it needs to work properly. These include a thermostat, ductwork, an evaporator coil, refrigerant and a condenser coil. While there are many other smaller parts of your system, understanding what these key components contribute can assist you in understanding how your entire centralized air conditioning system operates.

Setting Your Thermostat

To get your home to a desirable ambient temperature for your whole family, you’ll need to set your thermostat. This is the brain behind your entire air conditioning system as it tells the remaining system components when to turn on and off.

Your thermostat is typically installed on the main level of your home in an area that is considered near the middle. The placement of your home’s thermostat is very important because it determines the comfort level in your residence. If the thermostat is placed in direct sunlight, it will consistently read high and result in an overly chilled home.

Many centralized air conditioning systems come with a programmable thermostat. This essentially lets you easily program what temperature you want your home to be at throughout specific times of the day. This device promotes greater energy efficiency because you can program the thermostat to increase your home’s temperature when your family isn’t there. You can then program it to decrease the temperature to the desired level before your family arrives. This way, you can always walk into a comfortably cooled home.

The Indoor Blower Fan

When your thermostat determines that the temperature is above what you have set it to, it will turn on the entire AC system. The blower fan will pull air from the inside of your home through the return venting. This air will pass through both the air filter and the air purifier if you have one installed.

The air filter is a necessary component of your air conditioning system. It removes unwanted pollutants and debris from your air. This is essential to maintaining a high quality of air inside of your home. There are four different types of air filters that you can run in an AC system. These include pleated filters, reusable filters, HEPA filters and fiberglass filters. Some are disposable, and some can be cleaned. Consult your owner’s manual for specifics.

If you have an air purifier installed on your system, it will work to remove more unwanted particulates from your home’s air. There are four main types of air purifiers that you can have installed. These include media filters, electronic purifiers, PCO purifiers and combination purifiers. Media filters are the cheapest. While combination purifiers are more expensive, they are ideal for those with respiratory issues.

The Evaporator Coil and Refrigerant

As air goes through the filter and purifier, it will pass over the evaporator coil. Inside the evaporator coil, there is liquid refrigerant. As the warm air travels over the coil, the heat is transferred to the refrigerant. This heat changes the liquid refrigerant into a gaseous state.

During this process, excess humidity in the air is removed. The water simply drips off of the evaporator coil and into the drain pan. The water goes down the drain and out of your air conditioning system. The air that passed over the evaporator coil is essentially cooled because the heat and humidity are transferred out of it. This cooled air is then returned to the indoors of your home via the supply ducting.

Refrigerant Is Moved to the Outdoor Unit

The gaseous refrigerant is moved via insulated copper tubing to the outdoor air conditioning unit. This unit has a compressor that pressurizes the refrigerant and moves it through the condenser coil. In addition, there is an outdoor blower fan that pulls air from the outside through the condenser coil. The heat is dispersed through the outside air into the outdoor environment.

There are also metal fins attached to the condenser coil. These are aligned in a grated fashion, and they work to disperse the excess heat from the refrigerant. As this happens, the refrigerant returns to a liquid state. The liquid refrigerant will then make its way back into your home via the insulated copper tubing.

Refrigerant Expansion Valve

As the liquid refrigerant enters the inside unit, it will go through an expansion valve. This valve will regulate how much of the liquid refrigerant enters the evaporator coil. It also helps to reduce the pressure in the liquid refrigerant so that it’s able to turn back into a gaseous state when heat is transferred to it.

Once the liquid refrigerant enters the evaporator coil, the heat from the air will be transferred to it. This will turn the refrigerant back into a gaseous state, and the air conditioning process will repeat all over again.

The Various Types of Home Air Conditioning Systems

There are three main types of home air conditioning systems that homeowners utilize to stay cool in the hot summer months. You might have a split, packaged or ductless air conditioning system. Knowing how to identify your system is essential to understanding the position of the various air conditioning components.

Split system air conditioning units are the most popular option. They’re called split systems because the ductwork attaches to both the air conditioning unit and the heating unit, such as a furnace or boiler. This is the most common type of home air conditioning unit.

Packaged system air conditioning units have both the heating and cooling components combined in one outdoor unit. This type of system is ideal for homes that don’t have adequate crawlspace to install a split system air conditioning unit. Since all of the cooling and heating components will be outside, this system is more prone to damage from the elements, and it doesn’t last as long as a split system normally would.

Ductless air conditioning systems are ideal for existing homes that don’t have ductwork installed. This system consists of an outdoor compressor unit and multiple indoor wall-mounted air conditioning units. The wall-mounted units are individually controlled so they can be set at different indoor air temperatures. Each unit is connected to the outdoor compressor unit via copper tubing that is mounted to the side of the house.

How To Prepare Air Conditioner for the Summer

Written by Kevin on June 9, 2021. Posted in HVAC.

When the hot summer weather hits, you should already have prepped your air conditioning system to handle it. As a homeowner, taking care of your air conditioner should be another springtime maintenance task. In fact, there are many different preparation steps you will need to take to ensure that your air conditioner is ready to work through this upcoming hot summer season.

Program Your Thermostat

Most newer air conditioning systems have a smart or programmable thermostat. If your system doesn’t, then it is advisable to install one before the summer season hits. These are fairly simple to install as they just require connecting a couple of very low-voltage wires and inserting regular batteries. You’ll want to program your thermostat to remain at 78 degrees Fahrenheit when you’re at home and 88 degrees Fahrenheit when you’re not.

For most people, this means programming their thermostat based on their work schedule. Simply program your thermostat to increase to 88 degrees when you’re getting ready to leave in the morning and have it decrease back to 78 degrees about an hour or so before you expect to return home. Most programmable thermostats allow you to program each day of the week, so you can program your work schedule for Monday through Friday and have the weekend left at 78 degrees.

Change Your Air Filters

Depending on the unique air conditioning system that you have, you may have one or more air filters. When you’re prepping your air conditioning unit for summer, it is vital that you replace your air filters. If you know what the filter model is, or you know your air conditioner model, you can easily find new filters at your local hardware store.

Air filters are designed to stop unwanted allergens, dirt, and debris from floating around in your air. As the filter does its job, it starts to become clogged with all this excess unwanted debris. When you can no longer see through your air filter, it is time to replace it with a new one. When a filter is completely clogged, the air conditioner has to work harder to move air through the venting system.

Remove Condenser Covers

If your region of the country experiences a very harsh winter, you likely use condenser covers. These are specifically designed to be temporarily installed in your outdoor unit. They get placed over your condenser coils to protect them from extreme temperatures throughout the winter months. Before you can use the condenser coils as part of the air conditioning operation in your home, you will need to remove these condenser covers.

Clean Your Condensation Lines and Drain

A necessary job of your home air conditioning system is to remove excess moisture from the air. When the moisture is removed, it is directed down the condensation lines and to the drain. Unfortunately, these lines and the drain can get clogged. You may find unwanted dirt, debris, or even hard water buildup in these areas. It is a good idea to thoroughly clean your condensation lines and drain in the early spring so that these components don’t get clogged up during the hot summer season.

Clean Your Outside Unit

Your centralized home air conditioning unit has an outdoor compressor unit that helps to cool your home. Over time, excess dirt and debris from outside can find their way inside of your compressor unit. When this unit gets overly dirty, it can decrease the efficiency of your entire air conditioning system.

You should take the time to remove excess debris and trim back shrubs that are near your outdoor compressor unit. Temporarily remove its cover and clean out any leaves and other loose debris from inside of the unit. If you notice that any of the fins are bent, now is the time to bend them back into their original position. Also, you’ll want to use a chemical cleaner to remove gunk from the condenser coils.

Assess Your Concrete Slab

Your outdoor compressor unit is installed on a concrete slab. This slab needs to be level so that your compressor unit remains level during operation. If the compressor is tilted one way or the other, it can drastically reduce the efficiency of your air conditioning unit. Take a level and ensure that your concrete slab is level. If the slab is not level, you’ll need to remedy the situation by installing gravel under the slab or by using another leveling method.

Assessing Your Venting

The ductwork that connects to your air conditioning system runs throughout the walls and floors of your home. At each entryway into a room, you’ll find a vent. These vents need to be opened the whole way and free from any obstructions. It is highly advisable to take the time now to walk through all the rooms of your home and ensure your vents are open and there is nothing blocking them. It’s not uncommon to move furniture and accidentally block a vent without realizing it.

Evaluate Your Ductwork for Leaks

Any leaks that are present in your ductwork can drastically reduce the efficiency of your air conditioning system. Think about it like this: If your system is losing some of its cooled air, then it is going to need to make more to cool your home. Losing just 20% of the cooled air from your system can result in your air conditioner working 50% harder to adequately cool your home.

It is best to evaluate your ductwork to identify any leaks that are in it. While you may not be able to assess all of your ductwork because some sections are inside the walls, it is best to evaluate all the areas that you can get to. Even removing your vents and assessing what’s behind them is a necessity. If you do find some leaks, then you will want to use ductwork tape to seal them. Don’t settle for simple masking tape, as it won’t seal effectively. Make sure that you use foil tape that is specifically designed for ductwork to get the best seal possible.

Clean Out Your Ductwork

As the air is directed into your ventilation system through the return ducts, it can bring along dirt and unwanted allergens with it. These items can get stuck in the ductwork as the air moves. It is a good idea to consider having a professional company clean out your ductwork every couple of years. This can remove loose debris and ensure that the air in your home remains of high quality. This is especially important when you have family members with nasty allergies.

Why Does My Air Conditioner Smell?

Written by Kevin on May 24, 2021. Posted in HVAC.

An air conditioning unit’s prime purpose is to maintain comfortable indoor temperatures even during hot summer months. If you turn on your AC and it blows awful smells, this means that your unit has some underlying issues that require immediate attention. It might be challenging to determine the exact source of the smell, especially if you aren’t conversant with how an AC operates. Here are nine unpleasant and even potentially dangerous odors that can emanate from your AC.

1. Burning Electrical Odor

When you switch on your AC after having it off for an extended period, it might emit burning smells within the first few minutes. During periods of inactivity, the AC may accumulate dust, and when the unit heat-ups, it can produce a burning smell. The odor should dissipate on its own after a few minutes. If the problem persists, you might need to call a professional to assess the issue and make the necessary repairs.

The air conditioning unit contains various electrical components. If the AC smells like something is on fire, it probably means that your unit’s parts are overheating. This is a serious issue, and you shouldn’t attempt to fix it on your own. Immediately, shut off your system at the breaker box, and seek professional assistance. Other times, electrical odors can result from some mechanical problems with your AC fan or compressor. Planning for regular HVAC maintenance can help prevent such issues.

2. Rotten Egg Smell

The smell of rotten eggs from your AC signifies leaking gas. Though the natural gas used in air conditioners is colorless and odorless, manufacturers combine it with Mercaptan, giving it the stinky smell of rotten eggs to notify the user of a gas leak. Prolonged exposure to this gas can lead to lung irritations, difficulty breathing, severe headaches, confusion, loss of consciousness and mental fatigue.

Once you notice signs of a gas leak, switch off all electrically operated equipment, put out any flames and open the windows and doors to avoid an explosion or fire. Leave the house immediately, and contact your HVAC company to fix the issue.

3. Chemical-Like Smells

If your AC produces an odor similar to paint thinner or nail polish, it could emanate from fluids used within your unit. It signifies AC malfunction, and you should call your HVAC technician for a proper diagnosis. At other times, placing open paint containers near your system can result in recirculation of odors throughout the house. The AC may pick up the smells from inefficiently sealed containers and force the scent through the rest of the rooms. Look for all paint and chemical containers in your house, and store them appropriately to get rid of such smells.

4. Exhaust Fumes

Fluid leaks from vital AC components like the engine can cause the production of exhaust fumes. If your AC is faulty, it can emit a large volume of toxic gases. These fumes are dangerous. They deplete oxygen in your blood when inhaled and can cause an array of health issues. Once your AC starts producing exhaust-like fumes, have a technician inspect it to diagnose and fix the problem.

5. Musty Smells

A musty smell signifies the presence of mold and mildew within your unit. Excess moisture in the vents or air ducts encourages the growth of biological contaminants. If you reside in high-humidity regions and fail to turn on your AC for some time, the filters may accumulate dust and moisture, causing mold issues. When the air filters clog, they limit airflow, which causes water to collect on the evaporator coil. The moist conditions create an ideal environment for the growth of mildew and mold.

An inefficient drain pan and blocked condensate line can also encourage mold growth. Your vents will then begin to release musty smells. This could trigger asthma attacks and allergic symptoms, especially for people with compromised immunity.

The only solution for this issue is to find where the mold is and clean it up. If the problem persists, have a technician thoroughly clean the unit and fix any underlying problem to avoid mold recurrence.

Be aware that an oversized AC unit can also cause high humidity issues. It cycles on and off quickly, so it doesn’t efficiently draw out moisture from your indoor air. Have a technician determine the right unit size for your house by considering the square footage, number of occupants, local climate, insulation level and ceiling height.

6. Gunpowder Odor

The most common cause of a gunpowder odor from your AC is a shorted-out circuit board or fan motor. Exposure to these fumes can negatively affect your health. When you detect such smells, switch off your unit and have a professional perform an inspection before running the system again.

7. Rotten Carcass Smell

In extreme weather conditions, critters, bugs and birds tend to seek refuge in the AC compartments. Unfortunately, some might get stuck inside and die, thereby emitting unpleasant odors. Once you turn on your AC, it would then circulate a foul stench throughout the house. The only solution is to have the dead animals removed and the affected parts thoroughly cleaned. Getting rid of dead animals is an unpleasant experience that is best left to qualified technicians.

8. Strong Nicotine Odor

If your AC circulates air that smells like cigarette smoke, chances are that there is somebody smoking in your house. The filter and evaporator coil absorb these fumes, and whenever you turn on the AC, it recirculates a strong nicotine odor throughout the residence. These smells can cause headaches and allergic reactions.

Also, if you live in an apartment with interconnected plumbing or ductwork and your neighbor smokes in the house, the smells may seep into your indoor space. In such a case, you will need to change your air filters more often. Call an HVAC professional to clean and sanitize your unit. Also, encourage your home occupants to smoke outside.

9. Stinky Feet Smell

Sometimes, your AC may emit smells that are similar to dirty socks. This is a sign of bacterial growth in the condenser coil. Dirt accumulation and the presence of water in the drain pan allow bacteria to proliferate. Professional cleaning and sanitization of the coils can help resolve this issue.

Bottom Line

When your air conditioner emits unusual smells, it signifies failure of components or the presence of contaminants that lower indoor air quality. Trying to mask such odors with scented candles or aerosol spray will only make the air quality worse. Routine AC maintenance is the best way to protect your unit from unforeseen issues like odor emissions. While you can do some minor fixes to eliminate nasty smells from your AC, technical repair tasks require a professional approach. An experienced technician can address the root cause of the foul smell and clean or replace AC parts to restore the natural scent of your house.

Does Humidity Affect My Air Conditioner?

Written by Kevin on May 24, 2021. Posted in HVAC.

During the summertime, the outdoors can feel muggy and uncomfortable thanks to an average humidity level of 61% in Hanover and the surrounding areas of Maryland. There may be no escape indoors, though, if the humidity levels are too high in your home. Many people believe that AC reduces moisture in the air, but that is not always the case.

Signs of Too Much Indoor Humidity

It’s easy to tell when humidity is high outdoors. You perspire and feel sluggish, and the air just feels heavy. Noticing high humidity indoors, though, is not as easy. Some of the more common signs of too much indoor humidity are:

Wet, moist skin all over your body
Mildewy, musty smell
Water condensation on your windows
Mold growing in your bathroom, kitchen, and other rooms

Humidity not only takes a toll on your comfort, but it also affects your AC system.

1. Oversized Units Run More Often

The size of a residential cooling system is based on the cooling capacity, not the physical size. At Beltway Air Conditioning and Heating, we service many AC systems that are too big for the interior space. Many homeowners attempt to maximize their budgets by purchasing the largest unit they can afford. The end result, though, is that the unit runs in short cycles that are not long enough to remove moisture from the air. Not only do oversized systems add to a humid environment, but they also cannot cool the air properly.

2. Humidity and Single-Stage Systems

Modern AC systems come in single-stage and two-stage designs. A single-stage system is either on or off, whereas a two-stage system adjusts airflow based on the temperature difference. On humid, cooler days of the summer, a single-stage unit will run a shorter cycle compared to warmer days. This means that the humidity levels in your home remain high, and you feel uncomfortable.

3. Indoor Humidity and Older Units

Many of the homes that we service in the Hanover, Maryland, area have older air conditioning systems. Dehumidifiers are a modern update to cooling equipment. When it’s humid outside, your older unit does not remove the moisture from the air before distributing it throughout your home. No matter how low you set the thermostat, you simply cannot feel comfortable. You will also notice that certain areas of your home feel warmer. Older systems will run longer and more often to reach the desired temperature, and this results in more wear and tear on the parts. Over time, you may find that you’re paying for frequent repairs to keep the system running.

4. Humidity Reduces Cooling Capacity

Outdoor humidity causes condensation on the evaporator coil of your AC system. The moisture mixes with dirt and dust to create a sludge that covers the coil. When air flows over the coil, the dirt prevents proper contact with the coil, and the system cannot cool the air. Your AC unit will continue to distribute the moist, warm air into your home, and the system will likely run longer, costing you more in energy use.

5. Negative Air Pressure and Humidity

Your HVAC system runs with a bit of physics. In ideal conditions, the air pressure inside your home is neutral. This allows for a closed space for circulating air. If your AC system is pumping out too much cooled air, this creates a negative air pressure situation. Your AC unit attempts to regain balance by pulling in more air from the outside, and this outdoor air is muggy and humid. A cycle begins where the AC unit draws in more air that makes your house warmer, and then the unit runs longer and more often to cool the space. More air comes through the ducts, and a second negative pressure situation is created. Eventually, you feel incredibly uncomfortable, and you also face a higher utility bill at the end of the month.

AC Units With Built-In Dehumidifiers

Removing excess moisture from the air inside your home helps your air conditioner work more efficiently, and efficiency equals cost savings for your utilities. Although some newer units come with dehumidifiers, this feature is not intended to maintain healthy, comfortable humidity levels.

The Best Way to Manage Indoor Humidity

If your home feels muggy during the summer, the best option is to get a whole-home dehumidifier. The unit installs onto your existing HVAC equipment. You can set the dehumidifier to a specific humidity level that feels comfortable to you. The recommended level of healthy indoor humidity is 30% to 50%, and you can work within that range to find a comfortable personal level. Another tool for managing indoor humidity is to install a thermal expansion valve. The device increases the amount of humidity that your AC system removes from the air.

Should You Remove All Humidity in Your Home?

If humidity only makes us more uncomfortable during the summer, why not eliminate it completely? Moisture in the air does have some benefits, though. First, it helps to keep our sinuses and mucous membranes moist, and this reduces allergies, sinus infections, and breathing problems. Second, humidity in the air helps to keep plants thriving. Third, the wood furniture in your home benefits from a bit of moisture in the air. Fourth, humidity helps to control static electricity and protects your electronics. The key is to have the humidity within the normal range.

Other Tips for Managing Indoor Humidity

Once you install a whole-home dehumidifier from Beltway Air Conditioning and Heating, there are a few more things that you can do to keep the indoors nice and comfy. Keep the windows closed on the most humid days. Open doors and windows draw in the outdoor air that has more moisture. You should also avoid running your AC system on “fan only” during the summer. Even though the movement of air helps you feel more comfortable, it actually brings in more humidity. Ceiling and floor fans are a better option to improve air flow. You should also check for cracks around doors and windows. These little spaces are just enough for humidity to creep inside. You should also check your attic space for any openings where air can get inside.

AC Maintenance for Cool, Comfortable Summers

Beltway Air Conditioning and Heating offers routine maintenance services for your air conditioning system. We recommend that you schedule the service in the spring before you need your AC. During the appointment, our expert technician checks to make sure that your air conditioning is ready to handle the higher temperatures and humidity levels.

What Are the Major Parts of an Air Conditioner?

Written by Kevin on April 10, 2021. Posted in HVAC.

When it’s sweltering hot in summer, your air conditioner keeps your home cool and cozy. For your AC to be reliable and efficient, several components have to work together in harmony. In this article, we will look at the critical parts of an AC and how they function.

1. The Refrigerant Fluid

One of the most critical parts of your air conditioner is the refrigerant. The fluid is compressible, meaning you can pressurize it to increase its temperature. It also moves from the indoor and the outdoor unit to dispense heat outside.

The refrigerant cycle depends on two stages of the fluid. When it is in the form of vapor, it absorbs heat from the evaporator coils. In the liquid form, it transfers its energy to the condenser.

There are many types of fluids that manufacturers may utilize in a cooling system. Regulators have banned some coolants due to their toxic or flammable properties. That means when you have a refrigerant leak; a technician may not be in a position to refill it.

The two most popular refrigerants are R-12 (Freon) and R22. Several countries have banned R-12 versions, including the U.S., since 1996. Modern cooling systems use R22 refrigerants, which are safer than their predecessors.

2. The Evaporator Coils

The evaporator coil primarily consists of copper tubes with a liquid coolant. When indoor air passes over the tubing, they absorb heat. The amount of heat it can absorb depends on the pressure of the coolant. When it’s hot, the pressure is low. On the other hand, when it’s cold, the pressure is relatively high.

A fan inside the AC’s air handler facilitates the continuous movement of air through the coil. When the refrigerant absorbs heat, it turns into vapor under low pressure. In its vapor state, the fluid will use energy to return to its liquid form. The last stage of the process cools the interior further.

The evaporator coil can also capture some of the humidity inside the interior of your home. When vapor heats the coil, condensation takes place, and it then turns into water. The water flows into the condensate pan and then dispenses it away from your home.

3. The Condenser Coil

The condenser coil is responsible for the second half of the cooling cycle. When warm air leaves the evaporator coils, it is pressurized in the compressor. The compressor has a fan that blows air onto the condenser coil to absorb energy from the refrigerant.

The condenser’s tube material is copper to facilitate the absorption of heat energy. The assembly also includes multiple coils to increase the surface area in contact with the moving air. Once the refrigerant cools down, it turns into liquid and returns to the indoor unit.

For the evaporator and condenser coils to work effectively, they need to be clear of debris and dust. Otherwise, the dust will act as an insulation that hampers the transfer of energy to the refrigerant. The best way to avoid such issues is to organize for cleaning during routine maintenance. Cleaner components enhance efficiency and reduce the energy consumption of your system.

4. The Expansion Valve

When the refrigerant returns from the condenser, it first goes into the expansion valve of your indoor air handler. The expansion valve can optimize the system’s cooling effect by limiting its pressure before it enters the evaporator coils.

As a result, the liquid refrigerant getting into the evaporator coils is at low pressure and cool enough to absorb heat. The expansion valve is, in turn, controlled by a sensing mechanism that adjusts the pressure according to indoor temperatures. That way, the air conditioner can regulate temperatures more effectively.

5. The Compressor

Compressors perform two critical functions: pressurizing the refrigerant and moving it through the system. It can pressurize gas coming from the evaporator coils as it goes into the condenser. The higher pressure increases the energy of the molecules, and it gains heat. The high pressure is cooled in the condenser coil before it can absorb heat in the interior.

There are different types of compressors with varying features. But most will include a motor that requires routine lubrication. The motor bearings can succumb to friction, which may cause technical problems within your AC unit.

It is worth noting that ACs use a special kind of lubricant that does not react with the refrigerant. Other types of oil can be hazardous when it comes into contact with the coolant. That is why you should leave tasks such as troubleshooting intricate parts of ACs to professionals.

Some compressors are hermetically sealed, which means you cannot repair their internal components. In such instances, you may have to replace it to restore the efficiency of your air conditioner. If you suspect your AC has an issue, you can talk to Beltway Air Conditioning and Heating’s certified technicians in Annapolis.

6. Thermostat Devices

A thermostat is an essential device for efficient air conditioning systems. It takes the temperature of the room and sends that information to the cooling system. An inaccurate thermostat can overwork your AC and negatively impact the comfort of your home.

Your system may not regulate temperature properly if the device is in an inappropriate location. Areas with lots of ambient heat can change the temperature reading on your device. As such, the system can record incorrect temperatures and cool temperatures more than is necessary.

In the past, most devices were manual or electric but with a few features. Today, thermostats have many features such as wi-fi and programmable capabilities. A smart device can adjust your AC depending on your schedule or daily habits.

For example, you can turn down your AC when your leave home. You can then program it to turn on just before you get home. Wi-fi capabilities allow you to make adjustments on your smartphone or portable devices. That way, you can check on your AC when in your room or when you are away from home.

Heat Pumps and Variations in Cooling Systems

The parts of a cooling system may vary considerably depending on its working principle. One type of system that is becoming popular with homeowners is the heat pump.

A heat pump can heat and cool your home within the same unit. It has an indoor and outdoor air handler and a refrigerant that transfers heat from the indoors to the outdoors. In the cold season, it can reverse the cycle to heat the interior.

The heat pump can cool primarily by changing the pressure of the refrigerant in the indoor unit. That means heat pumps do not use resistance heating present in most conventional air conditioners. As such, it is a good option for low-cost cooling.

A heat pump efficiency can be up to four times higher than a regular AC. They can also provide warm water with temperatures of up to 176 degrees Fahrenheit. Even in the chilly winters in Annapolis, a heat pump can provide adequate and efficient heating.

Whenever you suspect there is an issue with your air conditioner, it is always wise to seek prompt repairs. Our BBB accredited team is always ready to inspect and fix your system. We can install heat pumps, furnaces, ductwork, and indoor air quality solutions. Consult Beltway Air Conditioning and Heating’s staff today and discover our A+ rated AC solutions.

How Do UV Light Indoor Air Quality Products Work?

Written by Kevin on April 6, 2021. Posted in Indoor Air Quality.

The beautiful flower blossoms of spring increase the presence of particles in the air. When your indoor air is not given the proper attention, it could increase the risks of respiratory illness and allergic reactions. Most households depend on the HVAC system to improve indoor air quality. Unfortunately, it’s easy to forget about HVAC unit maintenance until it malfunctions at the least expected times. When neglected, contaminants can multiply within your unit and recirculate them through the house.

Adding UV lights into your HVAC system is a solution that keeps your unit clean to circulate healthy air throughout your home. Here is a detailed guide that explores UV light facts to clear up some of your concerns and help you make an informed decision.

1. What Is an Indoor Air Quality UV Light?

This is an air-purifying technology that utilizes ultraviolet light to inactivate airborne pathogens, kill viruses, and remove mold and bacteria. There are various UV light indoor air quality products in the market today. Some come as standalone devices, while you can install others directly on your HVAC unit.

Although there might be concerns due to UV rays’ adverse effects, the technician fits UV-based air purifiers deep into the ductwork system away from human contact.

2. How Does It Work?

Convectional air conditioner filters work well in trapping large contaminants particles. However, some microorganisms may slip through the filters into your indoor air. The UV lights help eliminates such pollutants. An HVAC technician installs the UV lamp within the ductwork near the evaporator coil. It then emits germicidal light to act on the air that goes through the ductwork.

The UV light works by attacking and destroying the microorganisms’ DNA. It disrupts their reproductive cycle, which leads to germs elimination. Note that bacteria contain a single cell that relies on DNA to live. If the UV lights destroy the DNA, then it sufficiently damages the bacteria cell rendering it harmless. An efficient cooling system circulates air throughout the home several times. Therefore, the air will receive a disinfection treatment severally each time it passes through the UV lamp.

The indoor coil condenses moisture to lower humidity levels. It creates a perfect breeding site for both molds and bacteria. UV light can sterilize the coils in your air conditioning unit to prevent microbial growth.

Although some UV lights operate on a 24/7 basis, it’s a good idea to invest in the automated UV disinfection system. It enables you to control the amount of UV light applied to lower costs. Such a system efficiently works when installed near the air handler cooling coils. It quickly sterilizes the coils and the air passing through the cooling system. You only turn the UV lights on when needed to save on energy.

3. How Effective Are UV Air Purifiers?

The effectiveness of the UV light air purifying product will depend on various factors. It might vary based on whether the contaminants come into contact with the UV light. Other factors include the bulb’s material, the required light dosage, and the pollutant’s exposure time to the light. If properly designed and correctly fitted into the HVAC unit, the UV can deactivate most bacteria and render the remaining ones inert once they enter the body.

The rays also attack viral cells, eliminating the potential of contracting contagious diseases. Additionally, they eliminate mold and spores. However, bacterial and mold spores are usually very resistant, and you might need high UV light levels and longer exposure time to destroy them entirely.

4. Benefits of Using UV Air Purifiers

Installing UV lights in your HVAC unit helps reduce the threat of airborne illness. The UV lights act as a cleaning agent that eliminates microorganisms in the air, promoting wellness and overall health. It also helps keep the coils in your AC sterilized to prevent re-circulation of airborne pathogens so your household members will experience fewer instances of flu or cold. The ultraviolet light eliminates irritants in the indoor air lowering chances of asthma or allergies. When properly placed, the UV light significantly reduces fungal levels.

It also helps eliminate foul odors in the house. Volatile organic compounds are the primary sources of odors at home. They often lead to eye, nose, or throat irritations, and prolonged exposure can result in dangerous respiratory illness. Some primary VOCs sources in the house include tobacco smoke, cleaning products, paint, and perfumes. UV light can help eliminate volatile organic compounds from your indoors to freshen the air and improve comfort levels.

UV lights also help improve airflow and efficiency. When contaminants clog the parts of your HVAC unit, it will have to work extra hard to maintain the required temperature. It will therefore result in increased wear and tear in your system and higher utility bills. With the proper UV light, it helps eliminate such contaminants to restore your HVAC unit’s capacity. The smooth airflow also translates to fewer repairs, cleaner air, and prolonged HVAC unit lifespan.

5. How to Implement and Maintain UV Light Air Purifiers

Although UV lights can help kill numerous microorganisms, they are only effective when installed correctly. Note that improper installation could cause injury and substandard performance. The installation process involves accessing the ductwork or the coil cabinet. Hence it’s a good idea that you have an experienced technician handle it.

You also need to ensure that your AC undergoes the necessary repair and maintenance before UV light installations. Other times, you might need to replace the AC or add extra components before installing the UV lights into your system. Consult a professional, and they will advise you on the best possible cause of action.

An experienced technician will assess your needs and determine the best area to install the UV light, either at the air handler, ductwork, or the return air. Even after installing the UV light, you should maintain it periodically. The bulbs loosen and lose efficiency after some time, and you should have them checked and replaced annually to preserve the protective benefits of the UV lights.

Also, you should keep the air filters clean to improve your UV light’s performance. When dust accumulates and covers the bulb, it limits the amount of light cast on the flowing air, which reduces its effectiveness. Therefore, change or clean the filters after every three months. If you reside in extremely dusty areas or have a heavily shedding pet, change the filters every month.

Bottom Line

The use of UV light indoor air quality products has increased in recent years due to the desire to maintain safe indoor environments. If you or your house members suffer from breathing issues, allergies, or when you notice higher than usual rates of colds and other viruses, consider installing UV lights. They effectively eliminate pollutants in your HVAC unit or indoor air to create a safe home.

What Are The Most Common Indoor Air Pollutants?

Written by Kevin on March 20, 2021. Posted in Indoor Air Quality.

The air you and your family breathe in your home can be quite hazardous to your general health. That is especially true during the cold winter months when doors and windows are kept firmly shut and homes are made airtight to conserve energy. Indoor air pollutants have been linked to various health effects, including respiratory problems, chronic cough, lethargy, frequent colds, headaches, eye irritation, memory lapses and dizziness.

Once you identify or suspect the real culprits, you can significantly reduce or probably prevent many indoor pollutants. Here are some of the most common pollutants you can find inside your homes and ways to prevent them.

1. Mold

Mold refers to forms of fungi that can grow outside and indoors. Some types are usually harmless, while others are hazardous. Mold can easily trigger some allergic reactions in some individuals. The symptoms of these allergies can include headaches, skin irritation, nasal stuffiness, swelling, coughing, wheezing, throat or eye irritation. Mold might also trigger severe asthma attacks in some people.

According to experts, the key to eliminating mold in your home is keeping humidity and moisture levels in check. Clean up any spills and fix leaks in your house as soon as possible. Keep your bathroom windows open or keep your fan on when taking showers. Also, ensure that you vent all the appliances that generate moisture.

2. Asbestos

Asbestos refers to mineral fibers that occur naturally in soils and rocks. Due to its heat resistance or strength, asbestos is used in many construction materials, including roofing shingles and insulation. Asbestos is also used in cars’ friction products and as a fire decelerator.

Exposure to asbestos for extended periods can increase your risk of developing asbestosis, mesothelioma, or lung disease. If you have products in your home that contain asbestos, keep them in good condition or have them removed by trained professionals near you.

3. Secondhand Smoke

Environmental tobacco smoke or secondhand smoke refers to a mixture of smoke generated by burning tobacco products like cigars and cigarettes. Experts refer to secondhand smoke exposure as passive smoking. Short-term exposure to smoke can lead to throat, eye, and nose irritations. You can also experience various health issues like wheezing, bronchitis, lung cancer, and pneumonia due to long-term exposure.

Secondhand smoke exposure might also trigger asthma attacks in some individuals. To avoid this air pollutant in your home, avoid smoking cigars, pipe tobacco, or cigarettes inside your house. You can have a smoking zone outdoors in your yard, away from the main living area.

4. Nitrogen Dioxide (NO2)

NO2 is a corrosive and toxic gas from the nitrogen oxide family. It’s released from burning fuel, especially from power plants, trucks, and cars. When high levels of nitrogen dioxide combine with water, it can eventually form acid rain. This toxic irritates the respiratory tract, nose, eyes and throat. Moderate exposure to nitrogen dioxide can lead to chronic or acute bronchitis. People can also get lung injury or pulmonary edema when exposed to high levels of this reactive gas.

In low levels, nitrogen dioxide can lead to impaired lung function in vulnerable people like children, asthmatics and those with chronic lung disease. According to the EPA, it’s vital to ensure that all combustion appliances in your home are installed correctly, kept in good condition and used as directed by the manufacturers. Ensure that the air emitted by these appliances can easily flow outdoors to avoid indoor pollution.

5. Carbon Monoxide (CO)

CO refers to an odorless gas emitted whenever fossil fuels are incompletely burned. Gas heaters and kerosene lamps are the greatest indoor contributors of carbon monoxide, while vehicles are the main sources of this gas outdoors. CO prevents your body from utilizing the oxygen it requires to function normally. This invisible gas can lead to a fast heart rate, nausea, dizziness, headaches, and fatigue. If CO concentration is high, it can significantly reduce the oxygen being transported to critical organs, leading to death.

Carbon monoxide poisoning is a threat to enclosed indoor areas with poor ventilation because the gas is unlikely to occur in high levels outside. To prevent carbon monoxide poisoning in your residence, have all your heating systems inspected and maintained by a professional annually. You can avoid using gas stoves to heat your home, and don’t use any combustion appliance without vents inside. Also, ensure that all your combustion appliances are installed correctly by a professional.

6. Particulate Matter

Particle pollution or particulate matter refers to a combination of some solid particles present in the air. Some of the particles are so big that you can easily see them with your naked eyes, while others are too small, and you can only see them using a microscope. Most often, particulate matter results from complex chemical reactions from various contaminants produced by burning fuels. It can also be produced directly from other sources like beaches or construction sites.

In the long term, particle pollution exposure can cause severe health complications such as aggravated asthma, irregular heartbeats, increased respiratory symptoms, and even heart attacks. People with preexisting allergic reactions and respiratory illnesses are at a higher risk of suffering from the adverse effects of particulate matter. Work with a professional to determine the exposure level to this contaminant, and take the necessary actions to eliminate it from your home.

7. Wood Smoke

Smoke refers to a complicated composition of gases and particulate matter or fine microscopic particles generated when you burn wood and any other organic matter. As discussed above, the biggest health risk from wood smoke originates from the smoke’s particle pollution.

According to statistics, many people still utilize wood stoves for cooking their meals and warming their homes. These stoves provide the benefits of warmth and food, but they can also emit toxic smoke, especially if your house is not properly ventilated. Switching to newer technology will help minimize health risks caused by wood smoke and enhance the quality of air in your home.

8. Volatile Organic Compounds or VOCs

VOCs refer to gases released by certain liquids or solid substances. They include an array of chemicals that can lead to long-term and short-term health effects. VOCs can result from various products used in our homes, such as aerosol sprays, wood preservatives, pesticides, moth repellants, and stored fuels. Other items that emit VOCs include disinfectants, cleansers, dry-cleaned clothing, preservatives, paints, and air fresheners. Volatile organic compounds can lead to various health issues like headaches, throat, eye, nose irritations, and damage to the central nervous system, kidney, and liver.

Bottom Line

There are many sources of indoor pollutants, but this article has only highlighted some of the common ones. These air contaminants can affect your comfort and health. Some health complications can show up years later after long-term exposure or immediately after short-term or single exposure. If you suspect air pollution in your house or poor indoor air quality, it would be best to contact professionals from Beltway Air Conditioning and Heating to carry out an air quality assessment.
