What is Auxiliary Heat?

Written by Kevin on January 18, 2024. Posted in Heating.

Heat pumps are excellent for your home during cooler weather. They are mostly efficient, and they don’t leave a carbon footprint. But the colder it gets, the longer it takes for your heat pump to work. Temperatures below 35 can slow it down and cause it to produce less heat. An auxiliary heating system is an excellent backup that helps keep your heat going strong regardless of the weather.

Is Auxiliary Heat The Same as Emergency Heat?

Nothing is worse than having your heat go out during freezing weather. When that happens, you know it’s your heat pump. It can no longer keep up with the demand, so it stops working. If you don’t have a backup heat system, your only hope is to turn on the emergency heat.
When heat from another source turns on automatically, it is known auxillary heat.

Factors that Cause Auxiliary Heat to Come on

Auxiliary heat that comes on continuously and without warning is a cause for concern. The main reason is that it’s constant use can impact your monthly expenses. Auxiliary heat can run up your electric bill by as much as 50% because it uses more electricity than any other thermostat setting.

There are several reasons why your auxiliary heat turns on. Most of these reasons are connected to drastic changes in temperature. A sudden blast of cold wind from an open door or a faulty duct system can cause the system to turn on. Other reasons include increasing the temperature by more than 5° or a sudden change in the outside weather. Whatever the reason is, it’s a problem you should be aware of.

Whenever your thermostat is unable to produce sufficient heat, your auxiliary feature will turn on. It acts as a backup source that keeps
your heat going strong. Auxiliary heat should only run for a limited amount of time. If it stays on for an extended period, the issue could be a mechanical one.

One problem may be your heat pump. If it fails to turn on, it won’t produce any heat. If your heat pump keeps going out, it could be causing a major drop in temperature, which causes the aux function to turn on right away. Sometimes, your thermostat may be to blame. It may not be communicating with your heat pump at all. Failure of your thermostat to command your heat pump to turn on could be what’s causing the problem.

A bad fan motor could be another issue impacting auxiliary heat. It’s the part of an HVAC system that keeps your heat and air circulating. The fan motor works to distribute heat throughout your home. And when it stops working, your temperatures begin to drop.

Signs That Your Auxiliary Heat is Always On

Your auxiliary heat should not run unless your house is cold. But if your system stays in that setting for an extended period, there is a problem. Below are a few red flags to look out for.

A Sudden Spike in Your Energy Bill

A sudden surge in your energy bill is a sign of a problem. Your auxiliary heat may be working too hard to keep your home warm. An HVAC system that’s the wrong size for your home could be a part of the problem.

It’s odd for your auxiliary heat to turn on when the weather is warm. There are two possible reasons this may be happening. One is that you adjusted the thermostat 5° higher or lower than average. Otherwise, you could have a bad heat pump. If that’s the case, you should call an HVAC specialist immediately.

No Response to Thermostat Changes

If you want to shut off auxiliary heating, you can begin by turning down your thermostat. Getting it down to a reasonable level should solve the problem of a running auxiliary system. It’s best to try and cut it down by at least 5°.

If turning down your thermostat doesn’t work, try turning it off. If nothing happens, there is a problem. Your auxillary heating could be running because of a bad heat pump. If you’re living in a cold area, outside temperatures could be to blame. In areas where the temperature is 35° or below, auxiliary heat can turn on automatically. If that’s the case, it’s normal. The only time you’ll have a problem is when temperatures are around 50°-60°.

Defrosting in the Heat Pump

Thanks to advances in technology, HVAC systems are getting better. Built-in sensors have evolved to the point where problems are detected early on. In some cases, you may experience issues along the way. Your auxillary heat may overreact in some cases.

Ice that accumulates around your condenser coils will cause your aux feature to go into overdrive. When your HVAC system detects this problem, it sends your system right into defrost mode. Hot air is pulled from an external source and directed towards the condenser coils, where it melts the ice. When this happens, you will receive an alert. Meanwhile, your HVAC will switch to auxiliary mode to keep your house warm.

These problems are normal for colder regions. During a harsh winter, your system will continue to defrost periodically to keep itself running at an optimal level. In most cases, it only takes a few minutes to thaw out your condenser coils. In most cases, it’s nothing to worry about. But if your defrost kicks on too often or stays on for an extended period, you should call a professional.

If Your Emergency Heat Setting is On

Most HVAC units have a manual switch that allows you to turn on your emergency heat yourself. It can be used to turn on auxiliary heat as a backup source. However, it’s going to shut your heat pump off in the process. Your energy costs will rise because you’re relying on an alternative heat source. This is especially true if your home has a duel fuel system that uses the most efficient source at a reasonable cost.
An emergency heat system should only be used during extreme temperatures. Turning it on for extra warmth can cause your monthly energy rates to rise.

Sometimes, children may play with the thermostat and turn on your emergency heat. In this case, a simple reminder about not touching the thermostat should do. An excellent preventive measure would be to lock the thermostat in a glass case.

Preventive Measures

Taking care of your unit can prevent a lot of issues with auxiliary heating. The balance between energy costs and saving money involves a little prevention. A great way to start is by keeping your entire system clean. Start by wiping down the areas of your outdoor unit on a routine basis. Check your air filters and have them replaced as needed. Clear your vents and ducts of any dirt or clutter that impact air flow.

Call the Pros

If something goes wrong with your heat pump, call a professional immediately. It could be bad wiring or poor installation. If your pump is old or worn, you may need a new one.

7 Common Problems That Cause Musty ACs

Written by Kevin on January 18, 2024. Posted in Cooling.

Have you experienced a smell of stale food, mildew, or mold when you turn on your AC? Regardless of how you put it, you would agree that it is not a pleasant experience to have in your home.

The smell could indicate some underlying issues in your cooling system. Don’t ignore persistent musty odors, thinking that they are normal, or go the extra mile by masking the smell with air fresheners. The surest way to fix the problem is to get to its root. Track down the issue with the help of a qualified HVAC technician, as it is not only healthy but also adds comfort to your home and reduces the cost of HVAC repairs in the long run.

If you are wondering what could make your AC smell musty, there is no one cause. A variety of issues could cause it, so let’s look at some of the common causes that would make your AC emit such an undesirable odor.

1. Dirty Evaporator Coils

During the summer, your AC functions by removing humidity and heat from your home, resulting in a cooling effect. The role of the evaporator coil in the cooling system is to evaporate the moisture after absorbing the moisture and warm air indoors. It then cycles the air to bring back dry and cool air into your home.

If the evaporator coil is left dirty or frozen, it will not function optimally. This means that your house will retain humidity and warm air. The moisture will not evaporate; hence, it will remain trapped in your cooling system. The result is the eventual development of mildew and mold.

A professional technician has special tools that are effective in deep cleaning coils and disinfecting bioslime buildup without damaging the fins. If you have this problem, you can contact Beltway Air Conditioning and Heating to check the options available for your home.

2. Dirty or Leaky Air Ducts

As a homeowner in Hanover, the value of air ducts during the cooling season cannot be overemphasized. Air ducts are responsible for the circulation of air from your cooling system to all parts of your home. However, when mildew and moldy odors are trapped in the air ducts, they are also transported in the same manner as air to all parts of your house.

When you smell a moldy smell in your indoor air, hire a duct cleaning professional who can diagnose why exactly there is dirt circulating throughout your home. Read here to learn more about the benefits of frequent duct cleaning. Some of the particulates in your air may contain pollutants, diseases, growth, and allergens that can significantly impact the health of your family.

Here are some of the odor-causing things that can build up in your air ducts:

Pollen
Dust mites and dust
Fungi and fungal spores
End-products of tobacco smoke
Rodents and insects
Fecal matter
Mold
Pet dander

Ignoring the warning signs of the musty odor can expose you and your family to respiratory health problems and can worsen allergies and asthma attacks.

3. Excess Moisture in Vents or Ducts

One potential reason why you are smelling a musty odor in your indoor air is that there is excess moisture trapped in the vents or ducts of your cooling system. When humidity levels rise, moist air easily condenses on the cold ducts and vents, as they are made of metal. This results in the pooling of water, which then contributes to the buildup of mold, bacteria, and mildew behind the ceilings and walls. The result is nauseating fumes with a musty odor.

Beltway Air Conditioning and Heating can get your efficient humidity control services to help regulate indoor air moisture to prevent condensation. An HVAC professional will guide you on how to handle saturated insulation that could cause microbial growth behind walls.

4. Clogged Drain Pipe

A drain pipe helps drain water to the outdoor unit once it is collected in the drip pan. By its nature, a drain pipe operates in a moist and dark environment, which is a high-risk area for mold growth. The pipe is also vulnerable to clogging, which also results in a musty odor.

When dirt, debris, and algae clog the line, water backs up and leaks somewhere inside the pipes instead. This stagnant water breeds mold and bacteria, creating an unpleasant, decaying smell.

A professional HVAC technician has specialized tools that they use to dislodge the sticky mess. During installation, ensure that the drain line is capped outside to prevent re-entering more dirt.

5. Leaky Condensate Pan

If you notice that there is a puddle under your AC, it could mean that there is a crack or corrosion in the internal condensate pan. This is a common occurrence, especially for old cooling systems that have gone through constant condensation cycles. Mold grows as a result of water spilling through the pan to collect beneath your system and stagnate afterward, similarly to what may happen within your ducts if moisture is left unchecked.

6. Overfull Drip Pan

Your AC does not only help keep your home cool but also provides dry air by extracting moisture. The extracted moisture is collected in a drip pan.

In some instances, your drip pan could be damaged or corroded, which means that it cannot function as expected to extract and collect moisture from the air. Without anywhere to go, the moisture may build up in your cooling system. This will create an environment conducive to mold growth, resulting in a musty smell.

7. Oversized AC

Your home could smell musty because your air conditioner is too big for the space installed. This means that the AC will cool the air faster than it is intended to, which means it doesn’t dehumidify the air as well as the manufacturers specify. Hence, the remaining humid air will just circulate in your home. In such a scenario, without adequate ventilation to maintain the humidity levels, mildew and mold can grow, giving out an undesirable stench.

An oversized AC may increase your electricity bills while at the same time leaving your home smelling clammy and uncomfortable. We recommend talking to an HVAC technician to walk you through the journey of selecting the right size of AC according to your needs.

How to Measure Your Home’s Indoor Air Pollution

Written by Kevin on January 4, 2024. Posted in HVAC.

Maryland homeowners take great pride in their properties. They understand the importance of providing their families with safe and comfortable places to live. However, for a lot of homeowners, it’s easy to disregard indoor air quality and the role it plays in their comfort. Understanding, monitoring, and improving the air you breathe is crucial because poor indoor air quality can have detrimental impacts on your health and well-being. As your reliable HVAC and indoor air quality experts, we’ve put together this detailed guide to help you understand the importance of clean air in your home, how to spot the warning signs of poor air quality, and what instruments and solutions you can use to make the air healthier.

Benefits of Good Indoor Air Quality

There are a number of reasons for Maryland homeowners to improve the quality of air inside their homes. Good indoor air quality not only reduces the presence of airborne pollutants, but it also promotes respiratory health. This is especially advantageous to those with existing allergies or respiratory conditions. Air quality also affects how comfortable your home is. It eliminates unpleasant odors and provides a better living environment.

It’s also worth noting that indoor air quality affects how well you sleep. The dirtier the air, the harder it can be to fall asleep and stay in restful slumber. Poor indoor air quality also makes it difficult to focus, which can affect your productivity levels. Lastly, indoor air quality affects your furnishings and appliances. The dirtier the air is, the harder the HVAC system has to work to keep the home at a comfortable temperature. This can cause the HVAC system to endure lots of unnecessary wear and tear. As a result, poor indoor air quality can end up resulting in costly HVAC repairs and replacements.

Common Indoor Air Pollutants

Indoor air pollutants include a wide range of chemicals that have the potential to degrade the air quality inside dwellings. Allergens such as dust mites, pet dander, and pollen can all cause respiratory problems and allergies when they are present in high enough concentrations. Mildew and mold are health hazards because they multiply in wet places and release spores into the air. A number of common home items, including paints and cleaning materials, release volatile organic compounds (VOCs) that can irritate the respiratory system and your eyes.

Carbon monoxide, produced as a byproduct of combustion equipment, is a gas that may be lethal in large doses; it is colorless and odorless. A radioactive gas known as radon can seep into houses via the soil and cause lung cancer if inhaled. It is essential to identify and eliminate these contaminants to have a healthy home environment.

Signs of Poor Indoor Air Quality

When it comes to keeping a home a healthy and pleasant place to live, indoor air quality is paramount. There are a number of warning signals that poor air quality might send your way, and you shouldn’t disregard them. Improving the overall quality of the air you breathe inside the home and addressing any concerns requires you to recognize these indications.

Unpleasant Odors

To a greater or lesser extent, the presence of disagreeable smells is indicative of low indoor air quality. Mustiness, cooking fumes, or mold are all lingering odors that could be a sign of airborne contaminants. The first step in improving air quality and making a room more pleasant to live in is to determine where these smells are coming from and eliminate them.

Respiratory Issues

Coughing, sneezing, wheezing, or worsening allergies are typical symptoms of poor indoor air quality. A variety of airborne pollutants, including dust, pet dander, and mold spores, may aggravate the respiratory system and cause discomfort. You should definitely take action to improve the air quality in your home if you or anybody in your family has chronic respiratory issues.

Visible Mold or Mildew

Surfaces that have mold or mildew growing on them are a clear sign of high humidity and poor air quality in the home. Airborne mold spores are a health concern and a major factor in respiratory issues. To improve air quality and avoid future problems, it is essential to address the source of moisture, improve ventilation, and remove mold.

Excessive Dust Accumulation

Particles of dust, which might include pollutants and allergens, can impact how clean your house is. Excessive dust collection on surfaces, even after frequent cleaning, may indicate poor indoor air quality. To reduce excessive dust, it’s helpful to improve air filtration, use air purifiers and keep the surroundings dust-free.

Feeling Fatigued or Unwell

Indoor air quality might be a problem if you often feel sick to your stomach, lightheaded, or exhausted while you’re indoors. If you breathe in polluted air or have poor ventilation, you can experience these symptoms. If you find that getting outside makes you feel much better, it’s time to make some changes to your inside surroundings.

What Happens During Indoor Air Quality Testing?

To determine how healthy the air is in your house, a professional can do an extensive indoor air quality test. After an initial evaluation of your concerns and any visible problems, qualified experts carry out a comprehensive checkup. During the testing, experts will take air samples from different parts of your house to measure the levels of pollutants, allergens, and other particles in the air. Mold, radon, CO, and VOCs are some of the contaminants that may undergo targeted testing. After taking the samples, they are carefully analyzed to determine the kinds and concentrations of pollutants. Based on their findings, air purifiers, ventilation systems, and humidity controllers are some of the remedies that the experts might suggest to help you achieve better indoor air quality.

Types of Air Quality Monitors

There are several types of air quality sensors that you can use to improve your home’s indoor air quality. These sensors include smoke detectors, VOC detectors, and carbon monoxide detectors. VOC detectors help homeowners find and address high levels of VOCs. Carbon monoxide detectors identify the presence of this odorless gas, which can be deadly if left unaddressed.

Benefits of Whole-Home Humidifiers and Dehumidifiers

To create a healthy interior atmosphere and reduce the likelihood of respiratory discomfort and allergies, it is important to maintain regulated humidity levels. Dry skin, congested nasal passages, and static electricity are all things that a humidifier can help you avoid. These gadgets reduce the likelihood of mold and dust mite development by putting moisture into dry air. Dehumidifiers cut down on extra moisture, which means mildew and musty smells are less likely to be an issue. All of these things working in harmony make sure that your house stays at the perfect humidity level, which is good for your health and comfort.

How to Prevent Your Heat Pump From Freezing in Winter

Written by Kevin on December 22, 2023. Posted in Heat Pumps.

Although heat pumps are made to withstand the wrath of Old Man Winter, they can freeze up and cause you problems. But before you panic, remember that a little frost or ice on a heat pump is perfectly normal. Heat pumps are equipped with a defrost cycle, and with routine maintenance, they can quickly resolve icing issues on their own. However, you should take serious action to prevent damage to your heat pump if you see any of the following signs:

Entire unit is encased in ice
Frost is visible on coils but the frost signal isn’t triggered
The unit can’t pull air through the fins
Top of the unit and coils are coated with ice
The ice has been there for a while

This article focuses on what causes ice buildup on a heat pump and how to prevent it.

What Is a Heat Pump?

A heat pump is basically an air conditioner that runs backward to provide heat. They’re most often split systems, such as a combination of a furnace and air conditioning unit with the heat pump taking the place of an outside AC unit.

The systems are usually paired with a blower coil or air handler that connects to your ductwork system. Other heat pumps are wall-sleeve or packaged varieties used in condos or apartments.

A heat pump uses electricity to provide your home with both heating and air conditioning. They are very efficient at transferring heat to places where it’s needed. In summer, cooling is provided by transferring heat from indoors to the outside. In winter, a heat pump extracts heat from outside your home and moves it inside.

What Are the Main Types of Heat Pumps?

The thermal energy source a heat pump uses determines what type it is. Pumps that draw heat from the ambient air are classified as air-source heat pumps. Units that suck thermal energy from a stream or pond are known as water-source heat pumps. Those that draw heat from the ground or groundwater are known as ground-source or geothermal heat pumps. Absorption heat pumps that run on fossil gas are also available but aren’t effective for decarbonization.

In addition to how they gather thermal energy, heat pumps are also categorized by what they transfer energy to. An air-to-air heat pump collects thermal energy from the outside air and releases it indoors. An air-to-water system gathers warm air and uses it to heat water to circulate through radiators.

What Causes Ice Buildup in a Heat Pump?

Icing may occur if you have an issue with your heat pump’s blower. Make sure you can feel air blowing through the heat pump’s vent. If not, your home won’t receive sufficient heat.

A dirty filter can cause ice buildup. Always change the filter on your heat pump regularly. If your filter is clogged, the airflow will be compromised and it will be easier for ice to build up.

The debris that blocks the condensing fan’s motor blades can prevent it from functioning properly. These motor blades are located on the outside of the heat pump. Check around the condensing fan motor and clear away any dirt, twigs, leaves, or snow.

One cause of ice buildup that may go unnoticed is a drainpipe or gutter dripping from overhead onto the heat pump below. This is easily fixed by turning the gutter or pipe.

Moisture that builds up in below-freezing temperatures can cause an ice buildup. When a heat pump is set too low to the ground, the moisture can’t drain and quickly turns to ice. A simple solution is to use a base to prop the pump off the ground.

Ways to Prevent Ice Buildup

Have Your Heat Pump Installed by a Professional

Ice issues and other problems can occur quickly and often when a heat pump isn’t installed by professionals. The installation process involves multiple steps, and it isn’t recommended that homeowners undertake the task themselves. If you are considering converting to a heat pump for your home’s major heating source, let the professionals at Beltway Air Conditioning and Heating help you get years of service from your heat pump.

Schedule Regular Maintenance

Just like any HVAC system in your home, a heat pump requires regularly scheduled maintenance to operate effectively and efficiently. Contact a specialist from Beltway Air Conditioning and Heating for annual maintenance. Here are the regular maintenance tasks you can expect from us.

Check the airflow
Listen for unusual noises
Clean and/or replace filters
Clean the entire unit
De-ice if needed
Add refrigerant

Use the Defrost Cycle

Your heat pump’s defrost cycle automatically changes the valve to air conditioning mode. The outdoor fan shuts off and the evaporator turns into a condenser, heating up the refrigerant. In turn, the warmed refrigerant melts ice from the coils, a common place where ice is found.

If your heat pump is an older model, you must set the timer so the pump knows to switch to defrost mode. New models have automatic sensors that kick off the defrost cycle as needed. One works just as well as the other. Consult your owner’s manual to determine what model you have.

The defrost cycle is a critical feature in places such as the northern United States. These areas experience very cold winters. The unit reverses the flow of refrigerant through the coils automatically by going into a defrost cycle. Through reversal, the hot refrigerant flows to the frozen outside coils. Accumulated ice on the outdoor unit will melt quickly.

Temperature sensors inside the heat pump trigger the defrost cycle as needed and end it once the ice is melted. Since the defrost function doesn’t continuously run, energy efficiency is maximized. Each defrost cycle runs about 10 to 15 minutes and is usually enough to keep your heat pump functioning properly even in the coldest temperatures.

Use a Garden Hose

If your heat pump only has a small amount of ice buildup, you can use your water hose to melt away the ice with water. First, use your circuit breaker to turn the pump off to avoid an electrical shock. Once the power is off, grab your hose and spray the heat pump with water to melt the ice. Resist the urge to hammer or chip the ice away; you could damage your unit. If the temperature is on the temperate side, turn your heat pump back on and put it in fan mode to help melt the ice. For bigger problems, consult the professionals at Beltway Air Conditioning and Heating.

7 Helpful Furnace Troubleshooting Tips

Written by Kevin on December 4, 2023. Posted in Heating.

Your furnace is essential to your household’s comfort during the winter. It works hard to keep your home warm and protect your house from issues, such as frozen pipes. However, just like other vital systems, your furnace requires routine care to keep it in peak condition. When your heating system begins to malfunction, you can notice a range of symptoms from odd new odors to changes in your indoor comfort. Here are seven simple furnace troubleshooting tips you can employ before you call for help.

1. Check Your Furnace Filter

Your filter plays a significant role in how your heating system functions. This filter removes contaminants from the air to protect your air quality. When this filter fills up, it impedes airflow, which can make the system work harder and eventually lead to system burnout. If your furnace refuses to start up or stay on, it may be overheating due to a clogged filter. You should change your filter every 30 to 90 days depending on your household. They typically need to be replaced more regularly if you have a large family or live with pets.

2. Check Electrical Panel

Even if you have a gas furnace, the system still requires electricity to work. You’ll want to make sure the power that is running to your furnace is turned on at the circuit breaker. Look for the switch labeled HVAC and reset it. If you have a fuse box, you’ll need to replace any discolored fuses. You can then turn your furnace back on and see if it runs. If you notice that your heating system immediately powers back down after you start it up, there’s a chance it may be overheating or there’s an issue with the control board, and issues like these require professional help.

3. Check The Igniter

Electric furnaces use automatic electronic ignitions to start their heating process. When this component malfunctions, it will stop your heating system from starting. A faulty ignitor won’t be able to produce the spark necessary to kick on the burners. In gas furnaces, the pilot flame continuously stays lit, allowing the system to ignite its fuel from this source when it begins a cycle. There may be an issue with your natural gas supply or the burners, and you will know this if you notice the flame has turned orange or yellow or is flickering. The pilot light should always burn steadily blue.

4. Set Thermostat Correctly

Your thermostat is the brain of your furnace because it controls when it starts or stops running, and it also regulates the temperature in your home. If your thermostat is not set correctly, this can result in a myriad of problems.

One problem that results from incorrect thermostat settings is the furnace will either run for too long or not run long enough. The average furnace cycle length should last between 10 to 15 minutes. However, this will fluctuate depending on how cold it is outside and what type of furnace you use. Your heating system shouldn’t be staying on for upwards of 20 to 30 minutes at a time. The system also should not turn off shortly after it starts running, a problem that is commonly referred to as short cycling.

When your furnace refuses to start up, your thermostat may also be to blame. Check to confirm that the device is in the heat setting. If necessary, switch out its old batteries for new ones. Keep the location of your thermostat in mind because nearby heat sources, such as lamps, space heaters, or ovens, can impact its ability to accurately read the temperature of the environment. You can try setting the temperature several degrees higher to test your furnace. If your heating system doesn’t turn on or problems with your furnace persist, you need professional HVAC service.

Short cycling that persists after you have performed basic troubleshooting steps with your furnace may mean your furnace is overheating or triggering a safety mechanism. A furnace that continues to run much longer cycles even when the thermostat is working correctly can be the result of blower problems. You may have a blown fuse, or some of the wires inside the motor may be corroded.

5. Clean Out Your Condensate Drain

All the moisture produced by your furnace should be pumped safely out through the condensate line. High-efficiency heating systems tend to produce more water than standard furnaces, but you should still never see pools of water collecting near the base of your system.

If you notice that water drips from your furnace, you are contending with condensation. Condensation happens when your condensate drain is clogged. You can clean out your condensate drain by flushing distilled vinegar through your condensate line. Allow the vinegar to remain for 30 minutes, and then flush the condensate line with water. Once this process is complete, vacuum the condensate line with a wet and dry vac for three minutes. If these methods do not resolve the clog, you must contact a professional because the problem may be more severe, such as a broken condensate line or a more severe clog that you cannot dislodge. In some cases, your heat exchanger may be cracked and create excess condensation. It’s also possible your drain pan broke. It is important to rectify this problem quickly because frequent exposure to moisture can lead to premature rust and corrosion, lowering the overall lifespan of your system.

6. Check Your Vents

If temperatures are uneven in your home, check your vents to make sure they are not closed or blocked by furniture. If all your vents are free from obstructions and temperatures are still uneven, have a professional inspect your ductwork to see if there are any holes or gaps that allow air to leak out. Your ductwork may also have clogs that obstruct airflow to certain areas of your home, and these will need to be removed via a duct cleaning service.

7. Remove Clutter From Around Your Furnace

If you use your basement or utility closet as a storage space, make sure you do not have any clutter near your furnace. This is not only a fire hazard, but this can also interfere with how it functions because clutter can obstruct airflow. Always keep three feet of space around your HVAC system.

Leave All Major Issues Up to the Professionals

While there are many easy troubleshooting steps you can employ to fix problems with your furnace, all major furnace repairs should be left to experts. Trying to replace any internal parts or change the wiring can result in damage to the system. You may also inadvertently electrocute yourself, as furnaces utilize copious amounts of power that can be dangerous to untrained homeowners. Not to mention, you can void your manufacturer’s warranty if you have one.

6 Common Thermostat Issues and How To Solve Them

Written by Kevin on December 4, 2023. Posted in HVAC.

Although you might not think about it much, your home’s thermostat is critical to your comfort. It has the important job of sensing the temperature conditions in your home and activating your HVAC to meet your comfort preferences. When the thermostat is working well, it’s easy to ignore. When it’s not, however, your home’s comfort will likely be at the top of your priority list. Here are six of the most common thermostat issues and how you can solve them.

1. Your Home Never Reaches Your Desired Temperature

One of the most common thermostat problems occurs when you set your desired temperature, but your home never reaches it. This can happen for a variety of reasons. The first thing to check is whether your thermostat is in the proper mode. If it’s winter and you’ve left your thermostat set to cool, it won’t activate your home’s heat to reach the temperature you’ve set.

You should also check that your thermostat’s fan setting is in the auto position. This allows the thermostat to control the function of your HVAC’s blower fan as necessary. If you have it set to the on position, the fan won’t ever turn off and may interfere with your thermostat’s ability to reach your desired temperature.

2. Your Thermostat’s Temperature Reading Is Wrong

If you’ve ever noticed that your thermostat shows an indoor temperature that doesn’t match what you’re feeling, you may not be imagining it. It is possible for a thermostat to register an erroneous temperature for a variety of reasons. One of the most common is a dirty thermostat.

If it’s been a while since you’ve cleaned your thermostat, try dusting it to see if it fixes the temperature reading. You may also want to use a can of compressed air to blow out any dust that’s gotten inside the thermostat.

If cleaning your thermostat doesn’t do the trick, it may be miscalibrated. Most thermostats have a calibration mode that allows you to correct their temperature readings to compensate for installation conditions. To fix this problem you need to find your thermostat’s instruction manual. Using a thermometer, follow its calibration procedure to correct its temperature reading.

3. Temperature Readings Fluctuate

If you notice that your thermostat seems to read the temperature differently at different times of day, it may be installed in the wrong place. Your thermostat’s temperature readings can get thrown off by excessive sunlight, drafts, or any other sources of abnormal temperature fluctuations. However, fixing the problem isn’t necessarily easy.

If sunlight from a nearby window is interfering with accurate temperature readings, you can try to solve the problem using blinds or curtains. However, if your issue is hot or cold drafts that you cannot control, you might need to relocate the thermostat. Call Beltway Air Conditioning and Heating for help. Alternatively, you can purchase a thermostat with a remote temperature sensor and put that in a more appropriate and draft-free location.

4. Thermostat Display Not Working

If you try to set your thermostat and find that its display won’t turn on, don’t panic. If your thermostat uses batteries for power, it could be an indication that you need to replace them. This is usually as simple as opening a battery door, removing the old batteries, and inserting new batteries.

However, if you have a thermostat that relies on a C-wire for power, you could have a bigger problem. This might indicate something as benign as a loose wire, or it could indicate that there’s a problem with your HVAC control circuitry. You may also have a tripped breaker in your home’s main electrical panel. Of course, an inactive thermostat display could simply mean your thermostat has broken. To find out which, it’s a good idea to call Beltway Air Conditioning and Heating for a repair visit.

5. Your Thermostat Lacks Modern Features

Depending on when you had your home’s HVAC installed, your thermostat can be anywhere from a few years old to a few decades old. In the latter case, your thermostat might simply lack modern features. Older thermostats may not give you the ability to set heating and cooling schedules. They almost certainly won’t connect to Wi-Fi, allowing you to control your HVAC from your smartphone or voice assistant.

If you’re dealing with an old thermostat, you should consider replacing it. Doing so can be an inexpensive way to update your HVAC system to a more modern standard. This can improve your home’s comfort substantially, and that’s not all. A new thermostat could improve the efficiency of your HVAC and lower your energy bills significantly.

According to the US Department of Energy, even the simplest programmable thermostat can save you about $180 every year. That’s more than enough to pay for the upgrade in most cases. Even better, a smart thermostat could save you between 10% and 15% on your HVAC energy costs every year. Plus, you’d gain a plethora of new functions, including things like smart home integration, geofencing using your smartphone’s location data, and advanced data collection to better track your energy usage.

6. Your HVAC Keeps Running

Lastly, if your thermostat turns your HVAC on, but it keeps running long after reaching your set temperature, you may have a faulty thermostat. Fortunately, this is not a problem that happens very often. When a thermostat fails, it’s more likely to make your HVAC inoperable, not the other way around. However, if you notice that your HVAC keeps overshooting your set temperature by significant margins, it’s probably broken.

To solve the problem, you’ll need to replace your thermostat. If you choose to replace yours with a similar model, it may be possible to do the work yourself. However, if you use a thermostat failure as an opportunity to upgrade, you might need professional assistance. This is especially true if your existing thermostat is an older, battery-powered model, because your new thermostat may require some additional wiring to function.

7 Key Advantages of Oil to Gas Conversions

Written by Kevin on November 20, 2023. Posted in Heating.

Oil heating systems have been popular among homeowners for decades. Traditionally, oil heating systems use low-viscosity grades of fuel oil or other petroleum products to power the furnaces or boilers in order to heat up residential homes. While oil is a conventionally reliable source of heating, it has disadvantages ranging from indoor air pollution to the risk of oil spills. A look at the top benefits of converting to a gas heating system can help you make the best decision for your home.

1. Increase Energy Efficiency

According to the U.S. Department of Energy, household heating systems use more energy and cost more money to operate than any of the systems in the home. In fact, heating typically accounts for around 29% of the average utility bill. For this reason, it is important to choose an energy-efficient system. Gas heating systems are more efficient than oil heating systems. This results in lower energy consumption and can reduce your utility bills. For example, high-efficiency gas units can have an Annual Fuel Utilization Efficiency (AFUE) rating of up to 98%. This means that most of the energy output goes toward heating your home instead of getting lost in the combustion process. Instead of constantly restarting the heating cycle, a gas unit can thoroughly heat your home until the next session. This also reduces potential wear and tear on your heating unit.

In addition to potential utility bill and repair savings, converting to an energy-efficient system can have economic and tax incentives as well. According to the Environmental Protection Agency (EPA), the installation of ENERGY STAR-certified gas systems with an AFUE rating of greater than 97% may qualify for federal income tax credits. State and local regulations may also offer tax credits for home improvements that increase energy efficiency. Ask your local HVAC company for help choosing the right system, and be sure to save all receipts and records of installation for tax time.

2. Reduce Dependence on Foreign Oil

Did you know that the United States is the world’s greatest producer of oil? According to the Energy Information Administration (EIA), the U.S. produces 20.30 million barrels of oil per day. However, Americans are also the world’s top consumers of oil. This means the country still relies upon other nations like Saudi Arabia for the supply of oil. About one-fourth of this foreign oil passes through the Strait of Hormuz, the sole sea passage from the Persian Gulf to the open ocean located between Iran and the United Arab Emirates. Unfortunately, instability and unrest in this region can cause major spikes in the price of oil and impact the lives of families across the world. In contrast, natural gas has a much more stable price that is much less likely to fluctuate due to geopolitics or global conflict.

3. Lower Air Pollution

Gas heating systems are more environmentally friendly than other heating options. According to the American Chemical Society, residential heating oil is a source of air pollutants like fine particulate matter, sulfur dioxide, nitrogen oxides, black carbon, and volatile organic compounds (VOCs). In addition, oil heating systems can also emit greenhouse gases like carbon dioxide. Extreme greenhouse gas emissions contribute to the depletion of the ozone layer. Fortunately, gas heating systems operate using cleaner-burning fuel. The EPA’s Clean Air Act lists propane and natural gas as fuels that can help reduce your family’s carbon footprint. Natural gas is among the cleanest fossil fuels and can help ensure that you do not cause excessive ecological harm while heating your home.

4. Save Space in the Home

Another key advantage is that gas heating systems often require less than their oil counterparts. An oil heating system requires an on-site storage tank in an accessible area of the home for regular oil deliveries. This creates a much larger physical footprint and makes oil heating less desirable for many homeowners. In contrast, gas heating systems function more like other familiar utilities. A gas heating system connects to the municipal natural gas main line. Once a utility company or service provider turns on your home service line, you can begin using natural gas directly in your home. This means that you do not need to manage a large holding tank and can instead use the pipework connected to your home.

5. Simplify Logistics and Maintenance

Oil heating systems require frequent delivery of oil fuel to the point of use within your home. In addition, residential oil heating systems require someone to monitor fuel levels and schedule these deliveries whenever necessary. This makes them more complicated than gas heating systems that use a central distribution system to distribute fuel directly from the supply lines. In addition to oil delivery for the fuel tank, oil systems also require frequent maintenance. Because oil heating releases contaminants and particulate matter during combustion, these systems are subject to clogging or oil spills if left unattended for long. Instead of worrying about messy oil maintenance, you can switch to a gas system and then schedule the standard annual or semiannual maintenance checkups as needed.

6. Boost Home Resale Value

Converting from an oil heating system to a modern gas heating system may also increase your home’s resale value. According to a report from the Department of Energy’s Office of Energy Efficiency and Renewable Energy (EERE), installing an efficient natural gas system can increase a home’s resale from 2.0%-8.0%. The resale values also increase for homeowners who have ENERGY STAR-certified units within their homes. Similarly, a study from the Department of Energy’s Lawrence Berkeley National Laboratory found that energy-efficient gas systems can provide a 60% return on investment. Switching to a new system allows you to enjoy cleaner operation and boosts your home’s appeal to potential buyers if you ever decide to put it on the market.

7. Enjoy Increased Versatility

Gas heating systems are more versatile than oil heating systems. Traditional heating oil is more of a one-job material. Many homes primarily use it for air heating and rely on other energy sources like electricity to power their appliances. But once your home has a gas hookup, you can also convert your other appliances to gas. Examples of appliances that you can convert to gas include the water heater, oven, stove, swimming pool, washer, and dryer. You can also consider replacing your wood-burning fireplace with a gas fireplace instead. Natural gas fireplaces are less expensive than constantly replacing wooden logs, and gas fireplaces also produce on average 5% more heat.

What Certifications to Look for in an HVAC Contractor

Written by Kevin on November 2, 2023. Posted in HVAC.

HVAC technicians in Hanover, MD, are concerned with improved credibility and employment opportunities and the ability to provide greater services to their customers, pursue continuing education, and earn additional certifications. They understand the value that HVAC certifications bring in addition to on-the-job experience.

HVAC Licensing in Maryland

HVAC technicians help homeowners ensure that their HVAC system functions properly. Their job includes diagnosing and repairing issues and installing new HVAC systems.

An HVAC license offers customers a competency guarantee. When you hire a licensed HVAC technician, you know that you’re working with someone who has proven that they can pass all the required training programs and certifications and have garnered the necessary experience to diagnose and repair different HVAC issues.

Currently, Maryland offers five types of HVAC licensing certifications. These are apprentice, journeyman, limited, master restricted, and master. Before reaching each level, HVAC contractors must meet certain qualifications.

Apprenticeship

This is the starting point for all professionals in the HVAC industry. This license allows them to work under a licensed HVAC contractor.

Journeyman

With a journeyman’s license, a technician is proving that they have three years of experience as an apprentice and have at least 1,875 hours of working and training under an HVAC contractor.

Limited License

To qualify for this license, a technician needs to work as an HVAC journeyman for at least two years under the supervision of a master HVAC contractor. They need 1,000 hours of supervised work for at least one year before applying for the license.

Master Restricted License

In order to obtain this license, an HVAC tech will need to be a journeyman for three years working under a licensed master contractor. They will need 1,875 hours working like this before applying.

Master’s License

A master’s license requires an applicant to be a three-year journeyman working under an HVAC master contractor. They will need to complete 1,875 hours of work the year before applying. A master’s license means a person has a more in-depth understanding of HVAC principles than one with a master-restricted license.

EPA 608 Certification

This certification is required for HVAC technicians in harmony with the Clean Air Act. It is for individuals who repair, maintain, service or dispose of equipment that has the potential to release refrigerants into the atmosphere.

To obtain this certification, technicians need to pass an EPA-approved test. The test is specific to the equipment the HVAC tech will work on. They are administered by EPA-approved organizations. Thankfully, the Section 608 Technician Certification credentials do not expire.

The EPA has four types of 608 certifications. Type I is for technicians who work on small appliances. Type II is for technicians working on or disposing of high or very high-pressure appliances. Type III is for disposing of or servicing low-pressure appliances. Universal certification is for servicing equipment of all types.

NATE Certification

NATE, or North American Technician Excellence, represents a nonprofit certification group that centers on HVAC and refrigeration technicians. The HVAC industry develops, operates, supports, and endorses NATE.

The late 90s saw the founding of NATE, with a sharp focus on aiding technicians in elevating their knowledge and skills beyond the competition. NATE certification serves as proof of a technician’s proficiency in various facets of the HVAC industry. Pursuing NATE certification is a voluntary choice that allows technicians to showcase their industry expertise.

To acquire NATE certification, technicians must successfully pass a comprehensive written exam. These exams don’t simply test textbook memorization. They are designed to evaluate a technician’s real-world comprehension of air conditioners, oil furnaces, heat pumps, and more. The exam delves into intricate issues, ensuring that certified technicians possess in-depth knowledge.

In contrast to EPA 608 certifications, which have indefinite validity, NATE certifications are valid for five years. This finite duration reflects the ever-evolving nature of HVAC technology. Thus, NATE certification attests to a person’s up-to-date industry knowledge.

When you hire a NATE-certified technician for your property, you can rest assured knowing that you’re working with someone dedicated to correctly completing the job on the first try. You know that the technician possesses the training and expertise to effectively address any HVAC system issues, providing you with the peace of mind that the job will meet or surpass safety requirements.

HVAC Excellent Certification

HVAC Excellent Certification, widely recognized in the HVAC industry, applies to educators, technicians, and education programs, demonstrating the competence of certificate holders in HVAC and HVACR.

The ESCO group responsible for creating this certification aims to enhance technical competence within the HVAC industry. Established in the early 1990s, the Excellence Certification ensures a consistent education process that validates technicians’ competence in various HVAC areas.

HVAC Excellence Certification offers a series of discipline-specific written exams for professional technicians, each comprising 100 questions. These exams assess a technician’s competence in various areas, such as combustion analysis, heat pump installation, gas heat, residential air conditioning, electric heat, and more. Professional-level exams require technicians to have at least two years of verifiable work experience and pass the core exam before taking these exams.

Technicians can choose the disciplines they want to be certified in. Once a discipline is successfully completed and they receive their certificate, they can progress to the next level, aiming to become a master specialist in that particular discipline.

Hiring a Certified HVAC Technician: The Benefits

Hiring a certified HVAC technician offers several advantages, including working with a professional who comprehends the significance of delivering top-tier work and is committed to ensuring your HVAC system operates at its best.

Cost Savings

When you hire a certified HVAC technician, you save money. The job is completed correctly the first time, eliminating the need to pay someone else to re-do a subpar job.

Access to Professional Expertise

When you work with an HVAC professional who continually undergoes specialized training, their certificates demonstrate their adherence to local regulations and ability to address your inquiries regarding HVAC system issues while offering expert solutions to meet your needs effectively.

Safety Awareness

Working on an HVAC system can be hazardous for those lacking the necessary training and experience. When you partner with a certified professional HVAC technician, you can rest assured that they employ the latest industry methods to maximize safety while working on your system.

Heat Pumps vs. Furnaces: What to Know

Written by Kevin on November 1, 2023. Posted in HVAC.

Choosing between a furnace-based heating system or a heat pump for your Columbia home can be challenging. Both a heat pump and a furnace have the same purpose, which is to keep your home warm during the winter. However, they have drastically different approaches to providing heat. In certain situations, the heat provided by a furnace is best. In others, the heat from a heat pump is superior.

What Is a Heat Pump?

A heat pump is a system that can both heat and cool your home. Unlike a furnace that uses combustion to heat your home, a heat pump transfers the heat from the outside into your home. The heat is pulled from the outdoors and is transferred to a liquid refrigerant. This refrigerant is transferred to a heat exchanger, and air is blown across the heat exchanger, pushing the heat into the home.

Many people are surprised to learn that it does not need to be hot outside for a heat pump to be able to pull heat energy from the ambient temperature. A heat pump can work in temperatures that are below freezing. However, the colder it is outside, the less efficient a heat pump is to produce heat.

What Is a Furnace?

A furnace uses forced air to heat a home or office. Unlike a heat pump that transfers heat from one place to another, a furnace uses combustion or electric heating to generate heat. The heat produced in the burner is transferred to a heat exchanger. Then, a large fan pushes air across the heat exchanger, heating it and dispersing it through the home’s ductwork to individual rooms.

Primary Differences Between Heat Pumps and Furnaces

The purpose of a heat pump and a furnace is the same. They use some of the same components, such as the blower system. However, they have significant differences.

Heat Pumps vs. Furnaces

There are differences between heat pumps and furnaces that homeowners should consider before making a selection.

Heat Pump Cost

A heat pump will run you somewhere between $3,500 and $5,000 to install. However, other factors will determine the cost, including whether your home already has ductwork, the size of the home, the complexity, and the quality of the heat pump system you purchase.

The simplest, least expensive, and most commonly used heat pumps are air-to-air heat pumps. These will pull heat from the ambient air. Unfortunately, as the temperatures drop, these less expensive models start to experience problems.

Geothermal heat pumps pull heat from the ground. These take advantage of the fact that there is a constant 50-degree Fahrenheit temperature difference between the surface temperature and the temperature under the ground. Geothermal heat pumps are a lot more expensive than air-to-air models.

Furnace Cost

On average, you should expect to pay between $4,000 and $6,000 for a gas or electric furnace. Natural gas is more efficient than electricity. However, if your home does not already have a natural gas line, there is an expense in having one installed.

Heat Pump Efficiency

A heat pump is unbelievably efficient. They require a small amount of electricity to function, allowing them to transfer up to four times as much heat energy as the electric energy used to run the unit. The colder the temperatures are outside, the less efficient a heat pump becomes because it has to work harder to transfer enough heat to warm a room. Heat pumps become less energy efficient than a furnace at a certain temperature point, usually around -10 degrees Fahrenheit.

Furnace Efficiency

Furnaces use combustion to generate heat. Natural gas is a very effective heating option. However, it is way less efficient than a heat pump under normal conditions. A gas furnace is between 90% and 96% efficient. That’s the amount of heat produced through combustion that will be transferred into the home. An electric furnace, on the other hand, is 100% efficient. All of the heat created in the electric coils will be used to heat the home. The fact that a furnace creates its heat makes it a superior option in areas where temperatures during the winter are consistently below zero.

Furnace Durability

A gas furnace, as long as it’s properly maintained, will have a longer lifespan than a heat pump. Furnaces with proper maintenance can last for over 20 years. The heat elements of a gas furnace are only going to be used during the late fall, winter, and early spring months. This means that a furnace’s maintenance requirements are much lower than those of a heat pump.

Heat Pump Durability

A heat pump, similar to an air conditioner, should last around 15 years, having a shorter lifespan than a furnace. Since heat pumps can be used to both heat and cool the house, they will likely run all year round. Heat pumps may require more maintenance.

Heat Pump Appearance

Heat pumps are efficient and versatile, but they are not aesthetically pleasing. With a heat pump, you usually have a bulky standalone unit outside of your house. In the case of mini-splits, there is a large unit hanging on the side of the home on top of the home. These can detract from the aesthetics of the home.

Furnace Appearance

Unlike a heat pump, a furnace is unobtrusive. They are installed in the attic or basement, so they are out of sight and out of mind. This can be a factor to consider, especially if you live in a smaller home or have a smaller yard where you do not want to use up valuable real estate.

Heat Pump and Furnace Maintenance

A heat pump and furnace will require annual professional inspections and maintenance if you want them to work their best. Both systems also require homeowners to change filters and keep the area around the unit clean.

Heat Pump Versus Furnace: Which Is Right for Your Home?

Choosing between a heat pump and a furnace must be done on a case-by-case basis. In Columbia, Maryland temperatures can drop to around 25 degrees Fahrenheit during the winter. While this is still well within the range of a heat pump, it will take a heat pump a lot longer to heat the home at these temperatures than it will a furnace. On the flip side, a heat pump can provide an energy-efficient way to maintain comfortable temperatures in the home and can be used to keep the home cool during the summer.

Carbon Monoxide Detectors: Why They Are Important

Written by Kevin on October 20, 2023. Posted in Indoor Air Quality.

Though we often take precautions to keep ourselves and our homes safe, like child-proofing before a new infant or putting fresh batteries in smoke alarms, one measure often slips peoples’ minds: carbon monoxide detectors. At Beltway Air Conditioning and Heating, we want to help keep you and your Hanover family as safe as possible, including when it comes to carbon monoxide, or CO2. Read on for a rundown of carbon monoxide, CO2 detectors, and how they can impact your home.

What Is Carbon Monoxide?

Carbon monoxide is a dangerous gas that has no color, odor, or taste. When present, you likely will not notice it without some type of detection system, though some areas add a compound that smells like rotten eggs to help residents detect it. CO2 gas is flammable and can cause serious health issues when inhaled in high amounts.

How Does Carbon Monoxide Get Into Our Homes?

Carbon monoxide is released by burning fuels such as gasoline, natural gas, oil, kerosene, and charcoal. This gas often accumulates in poorly ventilated areas and from improperly installed situations.

Some of the top sources of carbon monoxide in the home include:

Gas appliances such as your stove, dryer, furnace, or water heater
Gas or wood fireplaces
Coal or oil furnaces
Wood stoves
Space heaters
Oil or kerosene heaters
Charcoal grills and camp stoves
Automobile exhaust fumes (especially dangerous in a closed garage)

How Can I Lower the Risk of Carbon Monoxide Poisoning?

When you know where carbon monoxide comes from, you can arm yourself with education and take steps to improve your home’s safety.

Some of the best ways to lower the risk of carbon monoxide poisoning in your home include:

Be sure all appliances are properly installed and vented
Have your furnace and fireplace inspected annually by a professional
Ensure your outdoor air intake for your furnace is not blocked
Do not burn charcoal inside your home
Never operate gas-powered engines in an enclosed space
Do not leave your car running inside the garage

What Effects Does Carbon Monoxide Have on Health?

Inhaling carbon monoxide can present symptoms that range from mild to severe or even deadly, depending on the concentration level of the gas and the length of exposure. Breathing in low levels of carbon monoxide may produce symptoms similar to the flu.

Some of the most common warning signs of CO2 poisoning are:

Headache
Nausea
Dizziness
Weakness
Confusion & disorientation

At higher levels in your home, carbon monoxide poisoning becomes very dangerous and can lead to serious illness, permanent mental and physical disability, and even death. Because you cannot see, smell, or taste the gas inside your home, many people don’t recognize carbon monoxide poisoning until it is too late.

Here are just some of the symptoms of high levels of carbon monoxide:

Sleepiness
Nausea & vomiting
Anxiety or depression
Confusion & disorientation
Impaired vision
Impaired coordination

Statistics show that more than 50,000 people visit emergency rooms every year for carbon monoxide poisoning, with over 400 deaths annually.

How Do I Know if Carbon Monoxide Levels Are Too High?

Having Beltway Air Conditioning and Heating install carbon monoxide detectors inside your home is the best way to be alerted to dangerous levels of carbon monoxide. You will not see, smell, or taste carbon monoxide at any level, so you need a detection system to monitor and alert you to its presence.

How Does a Carbon Monoxide Detector Work?

Carbon monoxide detectors are designed to measure the amount of carbon monoxide inside your home. There are different types of detectors that do this in different ways. Most devices work based on a chemical reaction occurring when levels are high enough to be dangerous. This monitoring happens continuously to constantly be on the lookout for carbon monoxide. The detection system then alerts you to the presence of higher-than-safe amounts of the gas.

Where Should I Install Detectors?

The National Fire Protection Association (NFPA) recommends having a carbon monoxide detector installed on every floor of the home and in a central location outside of each room where people sleep. There may also be local or state codes where you live that dictate placement and the number of detectors required in your home. Be sure to remember the basement and attic if applicable.

When installing your carbon monoxide detectors, first consult the manufacturer’s information. Some detectors should be mounted to the ceiling, while others are best installed on the wall a few feet lower than the ceiling.

Are There Different Types of Carbon Monoxide Detectors?

There are several different types of carbon monoxide detectors available. You may decide to choose one over the other based on your personal circumstances.

Battery-powered devices are portable and can be installed easily anywhere in your home.

Hardwired detectors are connected to your home’s power source and will continuously monitor the gas level in your home at all times when electricity is on.

Combination units use both battery and electrical power, using one source as a backup method if the other power source fails.

Most carbon monoxide detectors have an audible alarm that will sound continuously until manually turned off or the threat has diminished. There are also monitors with a digital display that show the level of carbon monoxide.

What Maintenance Is Needed for Carbon Monoxide Detectors?

Similar to smoke detectors, there are measures you should take to ensure your unit is still protecting you and your family.

Test your carbon monoxide detectors regularly to ensure they are still functioning properly. Most detectors have a test button on them. If you’re using a battery-powered unit, the batteries should be replaced at least once per year or as instructed by the manufacturer.

Regardless of type, your carbon monoxide detectors should be replaced with new units after several years, as dictated by the manufacturer of your specific model.

What Should I Do If My Carbon Monoxide Detector Goes Off?

If your carbon monoxide detector indicates a high level of the poisonous gas in your home, you should immediately leave the area. Step outside for fresh air and call 911. Seek medical attention for anyone displaying signs and symptoms of carbon monoxide poisoning.

Now that you understand what carbon monoxide is and how dangerous it can be, it’s time to make sure you have carbon monoxide detectors in your home. These detectors should be appropriate for your space and needs for best results. They also need to be installed properly in order to work correctly.

The best way to ensure proper installation and functioning of your carbon monoxide detectors is to call a professional. A trained and knowledgeable technician will know what type of detector is best for your home, where to install them, and how to install them. For this type of professional service, call Beltway Air Conditioning and Heating today. We’ll schedule a time to install units in your home and teach you how they work.
