The Hidden Dangers of a Leaky HVAC System

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

When you hear the word “leak,” you probably start to panic. Whether you’re dealing with a plumbing leak or a leak in your Hanover, MD home’s HVAC system, these are household problems that can lead to expensive issues. There are several locations and ways that your HVAC system can leak, including a leak of refrigerant or leaky ductwork. Let’s look at the hidden dangers associated with these leaks and the ways that you can address the problem.

HVAC Condensate Drain Leaks

There is a certain amount of condensation coming from your HVAC system as part of its normal operation. However, this condensation must be able to move away from your HVAC equipment and home. A condensate drain line allows for this process, but clogs and leaks can occur. This is usually a minor repair job if you spot the problem early on. A sign of this issue is pooling water around your heating or cooling equipment.

Leaks in Your Ductwork

The ductwork system in your home is designed to distribute conditioned air to your various living spaces. Holes, gaps, and cracks can occur in your ductwork, leading to air leaks. This can cause a big loss of efficiency. It can also impact your indoor air quality by introducing particulate matter into your circulated air.

Refrigerant Leaks

Refrigerant is a material that allows for a heat exchange to occur when you are running your air conditioning equipment. The design of your HVAC system typically keeps refrigerant in a sealed system, but leaks can occur because of damage or routine wear and tear. It’s dangerous to expose yourself to refrigerant. Low refrigerant levels can also cause your HVAC system to run more frequently to keep your home at a comfortable temperature. Refrigerant levels can be checked as part of annual routine maintenance.

What to Look For

There are some subtle, and not so subtle, signs that you can watch for that indicate there are leaks in your HVAC system.

Pooling Water or Dripping

It’s normal for a little bit of condensation to form around your air conditioning unit, especially if it’s located outdoors. However, pooling water or water stains around your furnace or other areas of your HVAC system is not normal. You may see an increase in the amount of water that is pooling if your system has been running more frequently than normal, as would be the case with extreme temperatures.

A Decrease in Efficiency of Your Equipment

If you have leaking refrigerant or leaking air, this can cause your HVAC system to run more frequently. This decreases the efficiency of your unit and can increase your utility bills. Keep an eye on your energy usage, which can indicate HVAC issues if there’s no other known cause for the increase.

Odd Sounds

Do you hear a rattling sound when your HVAC system is on? What about grinding, gurgling, or rattling? Odd sounds can indicate that you have leaks in your HVAC system.

Bad Smells

Gaps and cracks in your ductwork can introduce moisture into your system. This can quickly lead to mold growth. When mold spores circulate around your home, this can cause a musty odor. Not only is this smell unpleasant, but it’s dangerous to your health and wellbeing.

Hot or Cold Spots

Do certain rooms or areas of your home feel hotter or colder than others? These uneven spots can point to several HVAC issues, including ductwork leaks, refrigerant leaks, thermostat problems, and more.

HVAC Leak Dangers and Concerns

We touched on the dangers of mold growth in the home, which can lead to an increase in allergies, asthma attacks, and respiratory issues. There are other dangers that you should be aware of.

HVAC Equipment Damage

If you have HVAC leaks in your equipment or ductwork system, this can cause damage. This damage can lead to costly repairs. In some cases, this can shorten the lifespan of your HVAC system. Ductwork usually lasts for about 10 to 15 years. Furnaces and air conditioning devices last anywhere from 15 to 20 years. Eventually, our team may advise that you will need to replace your equipment or ductwork because repairs to them are becoming more frequent because of cumulative leak damage.

Household Damage

You may also see damage occur to areas of the home like your flooring, walls, ceilings, etc. when HVAC leaks are present. This can be expensive and inconvenient to repair.

Dangers to the Environment

Certain HVAC leaks can be dangerous to the environment. For example, refrigerant that escapes your closed system can release harmful gas into the air. Whenever work needs to be done to your air conditioning system that requires us to work on the refrigerant, there is specific protocol we must follow to prevent leaks.

Preventing HVAC System Leaks

While repairs can be made to fix the leaks in your HVAC system, routine maintenance and annual inspections can spot problems early on. This allows for minor repairs to be made before the issues get out of hand and become much more expensive. Maintenance can also prevent these leaks from occurring in the first place, keeping your energy bills low and helping you save money.

Other things you can do to minimize the risk of leaks in your HVAC system include having your ductwork sealed. Various products are available that will close any gaps, cracks, or holes that are in your system before they become larger. This is a relatively simple procedure that we can perform in one day.

Having our team monitor your furnace and air conditioner can help us spot problems with your drain lines, filter, coolant, etc. We can clean out your condensate line if it has a buildup of mineral deposits or sediment.

There are various seals that close your furnace, air conditioner, and ductwork. These seals can break down over time, causing leaks. Routine maintenance includes replacing these seals as needed.

It’s common for the bends and connections of your ductwork to break down over time. You can look for cracking, peeling, or other signs of damage that indicate the material is compromised and needs to be replaced. If you’ve recently had any remodeling work done in your home or you were moving items around the area of your furnace or ductwork, you may have inadvertently crushed areas of the ducts. Repairs or replacements should be completed before leaks cause problems.

Understanding Different Air Duct Materials

Written by Kevin on September 19, 2024. Posted in HVAC.

If you want an efficient and high-performing central HVAC system in your Hanover, MD home, you need efficient and high-performing ductwork to support it. HVAC air ducts are the distribution channels that deliver conditioned air to every room. With the right duct materials, you can minimize heat loss and heat gain during air delivery, protect your indoor air quality (IAQ), and limit HVAC noise. Read on to explore the different options in air duct materials and the benefits and drawbacks of each.

Sheet Metal Air Ducts Are the Most Popular Choice

Hands down, sheet metal air ducts are the most popular choice in the nation. They allow for a customized approach to ducting. Sheet metal workers can streamline these features to suit the needs and nuances of individual houses and HVAC equipment types. Some sheet metal materials are lightweight and flexible enough to bend around sharp corners. Flexible sheet metals can also be custom-fitted to suit tight spaces.

Research performed by the University of Florida found that HVAC air ducts can be responsible for the loss of up to 40% of an HVAC system’s heating and cooling energy. Fortunately, with tight fittings and professional duct sealing and insulation, sheet metal air ducts can experience minimal heat gains and heat losses. However, they aren’t without their drawbacks.

All sheet metal air ducts expand and contract when subjected to dramatic temperature and pressure changes. These movements often produce loud popping or banging sounds. If you want whisper-quiet HVAC operation, you might not get it with sheet metal ducting. Proper installation and quality insulation both have sound-dampening benefits, but movement-related sound invariably increases as sheet metal ducts near the end of their lifespans.

Stainless Steel Air Ducts

Stainless steel air ducts are chemical- and corrosion-resistant. They’re strong, highly rigid, and easy to maintain. They work well in hostile environments and in spaces where moving large volumes of air is required. Although stainless steel air ducts are an increasingly common choice for new homes, they’re most often used in commercial construction.

Stainless steel air ducts are the most expensive sheet metal duct type. Their high levels of rigidity also make them unsuitable for tight spaces, sharp corners, and sharply sloped ceiling areas. This is especially true when installing, modifying, or extending HVAC air ducts post-construction.

Galvanized Steel

Galvanized steel is the most durable and longest-lasting option for sheet metal ducting. It’s also significantly cheaper than stainless steel and a bit easier to adapt to tight, cornered, or otherwise awkward spaces. The smooth interiors of galvanized steel ducts are resistant to mold, mildew, and other fungal growths. They also allow for smooth, unimpeded airflow.

Among the many benefits of galvanized steel is its impressive fire rating. Galvanized steel has an A1 fire rating. Thus, these ducts can play an important role in slowing the spread of fires from room to room.

Unfortunately, galvanized steel is prone to rust and other corrosion. If you have consistently high humidity in your home, galvanized steel ducting could have a relatively short lifespan. To keep galvanized steel ducts in optimum condition, homeowners must:

Schedule annual HVAC service for all heating and cooling equipment
Perform regular air filter changes
Keep the perimeters of their outdoor condenser units clear
Regularly remove built-up debris from HVAC air vents

These and other ongoing maintenance tasks ensure good airflow and limit significant rises in humidity. Although they’re important for all HVAC systems, they’re critical for preserving galvanized steel ducting.

Aluminum Ducting

Though much less durable than galvanized and stainless steel, aluminum air ducts are valued for being both lightweight and flexible enough for easy installation in tight corners and small spaces. Aluminum ducts are also significantly cheaper than both steel types, and they offer good thermal conductivity. With professional duct sealing and insulation services, homeowners can limit their costs for HVAC air duct replacement and still enjoy high levels of HVAC efficiency.

Like galvanized steel, aluminum is prone to corrosion when installed in humid environments. Moreover, although it’s cheaper than galvanized and stainless steel, it’s more costly than fabric, plastic, and other non-metal ductwork materials. Due to its high malleability, aluminum ducting also requires special tools for installation, especially when this material is used for longer runs of ducting.

Mild Steel Air Ducts

Mild steel (MS) air ducts are often referred to as galvanized mild steel ducts. Like galvanized and aluminum ducts, they have low levels of corrosion resistance and aren’t suitable for humid environments. However, the high rigidity of MS air ducts allows for limited air resistance and promotes even and consistent air distribution.

This metal is incredibly ductile when heated. This makes it perfect for shaping, cutting, and otherwise altering to suit awkward or tight spaces. When used in residential HVAC systems, it’s typically for aesthetic purposes, such as when post-construction air duct installation results in exposed duct sections in visible areas. MS ducting also works well in non-load-bearing walls and other interior frameworks.

Flexible Air Ducts

Often referred to as flex ductwork, flexible air ducts are made from flexible metal, durable plastic, reinforced fabric, or fiberglass. These air ducts are easy to install, low in cost, and flexible enough to suit a broad range of applications. They work exceedingly well in tight spaces and corners. They’re also virtually soundless. Flex ducts are an excellent choice for affordable and all-around quiet HVAC installations. However, flex ducts have shorter lifespans than most rigid ducting. They’re also more difficult to clean.

Fabric Air Ducts

Also known as textile air ducts and air socks, fabric air ducts are porous, lightweight sleeves installed instead of metal or fiberglass ducting. Textile ducts are customizable, easy to install, and significantly less expensive than sheet metal. They also allow for even air distribution by preventing radical changes in static pressure. Given that fabric doesn’t expand or contract when exposed to temperature extremes, it’s also among the quietest ductwork materials currently available.

The drawbacks of fabric air ducts make them unsuitable for some homes and building areas. For instance, they’re less durable than most HVAC air duct types. They’re also more easily entered by pests and damaged by moisture, UV rays, and other exposure.

Fiberglass Air Ducts

Fiberglass air ducts have a lightweight sheet metal construction and a thick interior lining of fiberglass. This offers superior insulation and sound-dampening. Fiberglass air ducts work well in highly corrosive environments due to their excellent corrosion resistance. They’re also mold-resistant. As an inorganic material, fiberglass is less susceptible to mold problems, although not entirely invulnerable.

When the fiberglass lining in these ducts gets wet or contaminated with mold or other fungi, the U.S. Environmental Protection Agency (EPA) recommends replacing all affected materials. The intensive cleaning that wet or moldy fiberglass ducts require can shorten their lifespans. It can also dislodge micro-fine particles of glass that enter HVAC systems.

PVC Air Ducts

For high-humidity and corrosion-prone environments, PVC air ducts are an excellent choice. PVC has impressive insulating properties and high levels of moisture resistance. Though not as affordable as flex ducting, it’s less expensive than all sheet metal types. The primary drawback of PVC ducting is its limited heat resistance. Thus, you can’t use PVC if you have a gas-fired furnace for winter heating. However, it does work well with the lower operating temperatures and radiant heating supplied by heat pumps.

How Does Humidity Affect Indoor Comfort?

Written by Kevin on September 12, 2024. Posted in Indoor Air Quality.

When it comes to interior comfort, humidity is a major factor. We are all vulnerable to the negative effects of excessive or inadequate humidity on our health, our homes and our quality of life. If homeowners are aware of these effects, it becomes easier to make a home healthier and more pleasant place to live.

Dry Skin and Irritation

Keeping our skin supple and healthy requires a specific amount of moisture. Skin dryness and irritation are two of the most noticeable symptoms of low indoor humidity. Extremely dry air, especially in the winter when heating systems are running, can even cause skin to become flaky, dry, and cracked. This can be especially problematic for people with sensitive skin or skin problems like eczema.

Increased Risk of Respiratory Issues

Air humidity is an important factor in lung health. Mold, mildew, and dust mites — all of which can cause allergic reactions — grow easily in environments with too much moisture. Allergies to these substances can set off episodes of asthma and other respiratory difficulties and allergic responses. Conversely, when relative humidity is low, nasal and pharyngeal mucous membranes become less lubricated and less effective at capturing and expelling airborne pathogens. As a consequence, respiratory problems are more likely to arise, making infections and diseases more prone to spreading easily.

Dehydration

The use of heating systems during the winter months can cause low indoor humidity, which can lead to dehydration. Increased fluid loss through the respiratory tract and skin occurs when air becomes drier because it takes moisture from our bodies. Symptoms include dry mouth, headaches, and exhaustion. Neglecting to treat dehydration can lead to more serious health complications, such as kidney issues or, in the worst circumstances, heat-related diseases.

Worsened Cold and Flu Symptoms

When breathing dry air, the nasal passages can become inflamed and dry, making it more difficult for the body to ensnare and eliminate germs. Not only can this prolong the effects of common colds and flu, but it can also make them worse. A dry throat, for instance, can cause itching and pain, while a dry nose can cause stuffiness or even bleeding. Improving the relative humidity in your house can help reduce these symptoms by maintaining moist mucous membranes, which are better equipped to fight off illness.

Increased Risk of Static Electricity

When there isn’t enough moisture in the air, electrical charges can accumulate on surfaces and garments, a phenomenon known as static electricity. Because of this, touching metal items or other people might cause unintended shocks. It can be annoying since it messes with gadgets and makes managing things like clinging clothing or frizzy hair a real pain. The presence of static electricity is a key sign that the humidity level in your home might be too low.

Difficulty Sleeping

Humidity levels, whether too high or too low, can impact how comfortable and pleasant sleep is. Because perspiration takes longer to evaporate in damp air, being in a humid environment hinders the body’s ability to cool down. As a result, the air may feel warmer than it actually is, which can cause discomfort, restlessness, and trouble falling asleep. Low humidity can cause dry airways and nasal passages, which in turn can also make it uncomfortable and difficult to breathe easily when sleeping.

Increased Perspiration

You might perspire more than normal if the relative humidity in your home is high. Sweat is the body’s natural way of cooling itself, but when the air is too humid, it can’t evaporate as quickly. In addition to adding to the risk of overheating, this can cause an unpleasant, sticky sensation. When combined with physical exertion, it can lead to heat stroke or heat exhaustion in the worst-case scenario.

Dry Eyes

When relative humidity is low, it can irritate and dry out the eyes, which is bad for eye health. This is because the tear film, which typically covers and protects the eyes, can evaporate more quickly in dry air, leaving them vulnerable and uncomfortable. A gritty sensation, redness, and itching are signs of dry eyes, which can make it feel like something is in the eye. Low humidity can also make wearing contact lenses uncomfortable and can potentially raise the risk of eye infections for some people.

Damage to Wood Furniture and Floors

Wood has a natural tendency to absorb and release moisture, depending on the humidity of the air around it. Cracks, splits, and warping can occur when wood dries out due to low humidity. This can cause major problems with wooden furniture, flooring and other home furnishings. Wood, particularly flooring, can swell and buckle in extremely humid environments.

Increased Energy Bills

Because humidity determines how pleasant a particular temperature is, it can have an impact on your energy bills. You may need to turn on the air conditioner more often to stay comfortable indoors when the humidity is high because it makes it seem hotter than it actually is. The opposite is true during the winter months when low humidity could make the air feel chillier and cause you to crank up the heat. In both cases, energy use and associated expenses rise. Keeping the relative humidity in your home at a steady level will help you save money on your energy bills and make your house more energy efficient.

Whole-Home Humidifier

Adding moisture to the air that circulates through your home’s HVAC system is how a whole-house humidifier works. The standard installation method entails integrating it into your HVAC system and linking it to the ductwork. Humidifiers work by evaporating or dispersing water before distributing the resulting humidified air throughout a home. All whole-house humidifiers, whether steam, bypass, or fan-powered, work toward the same goal: a constant relative humidity within the house.

Whole-Home Dehumidifier

When installed in a home’s HVAC system, a whole-house dehumidifier can remove up to 80% of the moisture from the air. Once installed in the ductwork, it takes in humid air, cools it down to make it condensation, and then releases the collected water through a drain. The system then reheats the dried air and distributes it back to the living areas. By regulating the relative humidity within a space, this system not only improves air quality and decreases allergens, but also helps keep mold, musty smells and structural damage to wood at bay.

Humidity Control for Ductless Homes

The lack of central ducting makes humidity management more difficult for ductless dwellings. On the other hand, there are workable answers. Some ductless HVAC systems, including heat pumps and mini-split air conditioners, include dehumidification capabilities that allow them to control the relative humidity in a room. Another option for managing high humidity is to install independent dehumidifiers in strategic locations. You can even get whole-house humidifiers in the form of freestanding units that you can put in any room you like.

Pros and Cons of Ductless Mini-Splits

Written by Kevin on September 5, 2024. Posted in HVAC.

One type of HVAC system that’s gained a lot of popularity over the past 20 years is the ductless mini-split unit. This type of system allows you to enjoy all year-round comfort without the need for any traditional ductwork. If you’re in the market for a new HVAC system, it can be helpful to understand both the benefits and drawbacks of this type of system.

Heating and Cooling

Probably one of the most significant benefits of a ductless mini-split system is that it offers both heating and cooling capabilities. You no longer have to invest in two different types of HVAC systems to keep your family comfortable throughout the year. Now, you can purchase one system to handle all your comfort needs.

No Ductwork Needed

One of the biggest problems with older homes is that they don’t always have ductwork. It can be extremely expensive to have ductwork put in your home after it is finished. This is because flooring and walls will need to be removed in order to gain access to the appropriate areas to install your new ductwork. When you opt for a ductless mini-split system, you won’t need to worry about any of that invasive installation.

All these systems require is a small hole on the exterior wall of each room that gets a mini-split unit. This makes them the perfect heating and cooling solution for home additions where you can’t connect onto existing ductwork.

Energy-Efficient Operation

Ductless mini-split systems offer energy-efficient operation. In the summertime, they tend to operate more efficiently than traditional central air conditioning systems. This is mainly because they don’t lose any of their cold air through gaps in ductwork since they don’t use it.

In the wintertime, these units can be extremely energy-efficient when they operate in mild climates. Unlike traditional heating systems, the ductless mini-split unit does not create heat. It simply transports heat from one location to another. This can allow it to reach efficiency levels of up to 300 to 400%.

Federal Tax Rebates

Because ductless mini-split systems are so energy efficient, they qualify for a federal tax incentive. Under the Inflation Reduction Act, homeowners can receive 30% of the total cost of their mini-split system back in the form of a tax rebate. They can claim amounts up to $2,000. Even some local municipalities and state governments are offering their own tax incentives for homeowners who invest in these energy-efficient products.

Zone Temperature Control

If you have a mini-split system installed in your home, you will have individual units in each main room. Each unit will come with its own remote that will allow you to set individual temperature settings. This gives you the ability to enjoy zone temperature control throughout your entire home.

Instead of relying on just one thermostat for your entire home, you can enjoy setting a specific temperature for each room. This not only will go a long way in enhancing your overall comfort, but it can provide other benefits as well. You can enjoy fixing hot and cold spots throughout the year. This also gives you the capability to be more efficient with your energy usage.

Quiet Operation

One of the more annoying parts of forced air heating systems is the movement of air through your ductwork can be quite loud. When you get a ductless mini-split system, you don’t have to worry about the noise. These units operate at a noise level similar to a whisper.

Better Quality Air

Another area where ductless mini-split units outperform traditional forced-air HVAC systems is when it comes to air quality. Systems that rely on ductwork tend to experience more buildup of airborne debris that can reduce the quality of air inside your home. On the other hand, ductless models don’t have to deal with that excess buildup. Rather, each unit has its own filter that removes contaminants from the air as air circulates through the unit. This leads to better overall indoor air quality than with a traditional forced air heating or cooling system.

Dry Mode for Humidity Control

One feature that many new ductless mini-split units come with is dry mode. This works to remove excess humidity from the air without exerting the normal amount of energy to cool your air. It does this by pulling air over the evaporator coils at a much slower operating speed. By removing excess humidity without running your system at full speed, this system can allow you to be more comfortable in your home. Traditional central air conditioning systems must be running in cool mode to offer any sort of humidity control.

Not Efficient in Cold Climates

One major drawback of ductless mini-split units is that they don’t function efficiently at below-freezing temperatures. When temperatures get too cold, they’re unable to extract heat from the air outside. Instead, these units switch to their auxiliary heating mode, which works very similarly to a heating element inside an electric furnace.

Unfortunately, when in auxiliary heating mode, these units are going to be quite expensive to operate. One alternative that a lot of people use in colder climates is a backup heating system. This system will allow you to enjoy all the energy efficiency that comes with your ductless mini-split system when temperatures are above freezing. However, when temperatures dip down below freezing, you can switch to using your backup furnace to enjoy more affordable operating costs than if you were to rely solely on auxiliary mode.

Wall Units Can Be Ugly

Traditionally, ductless mini-split units were only available in wall-mounted models. These are a decent size box that is about one to two feet long by around eight inches high. Unfortunately, they’re not the nicest thing to look at as they stick out from your walls. This can be a big drawback for some people. It’s important to note that modern-day mini-split units are also available with floor-mounted and ceiling-mounted units, with the latter being the more discreet of the two.

More Maintenance

Another drawback of mini-split systems is they do require a little bit more maintenance than your traditional forced-air heating and cooling systems. The main difference in maintenance has to do with the filter. Each mini-split unit will have its own built-in washable filter. This will need to be washed every few weeks to ensure optimal efficiency. With traditional HVAC systems, you only need to change out one filter every two to three months.

Bigger Rooms May Need Multiple Units

Another known disadvantage of mini-split units is they can only handle so much square footage per unit. Your HVAC technician will have to determine the square footage of each room and pick a unit that matches that. Unfortunately, there may not be units big enough to cover the entire square footage of your bigger rooms. In this case, you may have to purchase more than one unit to handle your larger rooms.

Reliable Ductless Mini-Split Service

13 Factors That Affect HVAC Efficiency

Written by Kevin on August 20, 2024. Posted in HVAC.

HVAC efficiency refers to how efficiently your system converts energy into the cooling, heating, and ventilation you require. The more efficient your system is, the cheaper it is to run. There’s also the matter of environmental impact. HVAC is the number one contributor to the average American household’s carbon footprint. Let’s explore 13 factors that shape your system’s efficiency.

1. Efficiency Ratings

There are three core energy efficiency ratings that the Department of Energy (DOE) uses to set standards for the American consumer. In all cases, the higher the number, the more efficient the system.

Annual fuel utilization efficiency (AFUE) indicates how much fuel a furnace or boiler wastes in the conversion process. An AFUE 81 furnace wastes 19% of the fuel it converts into heat energy.

Seasonal energy efficiency ratio (SEER) measures cooling efficiency over an entire cooling season. You can use SEER not only to compare air conditioners but also heat pumps in cooling mode.

Heating seasonal performance (HSPF) is like SEER but measures heating efficiency. This is necessary for heat pumps, which transfer heat energy rather than generating heat as a furnace does.

2. Climate

In general, extreme temperatures will negatively impact HVAC efficiency. This is why the DOE sets the minimums for energy efficiency by region rather than nationwide. It’s also why northern homeowners have been slower to adopt air-source heat pumps, which run less efficiently in very cold temperatures.

3. Building Envelope

The building envelope of your home refers to its seal. A home with a tight seal will be very efficient. Homes with loose seals will waste more heating and air conditioning. Aspects that make up a building envelope include the roof, doors, windows, insulation, foundation, and so forth. One way to assess your building envelope is to schedule a home energy audit. You can then use this information to target the aspects of your home that are undermining HVAC efficiency.

4. Sizing

Size in the HVAC world refers to the overall capacity of the system. You neither want an undersized nor oversized HVAC system. The goal is to get it just right. An incorrectly sized system will cycle too frequently or for too long a period. That will drive up your operating costs. It will also increase wear and tear, which will make repairs more common and decrease the equipment life span. This is one reason why it is so important to hire a professional installer who will perform a load calculation for your home.

5. Thermostat

A thermostat is integral to efficiency because it reads the temperature in the home and dictates the heating and cooling cycles. It’s important to have a thermostat that’s centrally located and that has an accurate temperature sensor.

Programmable and smart thermostats can make your system even more efficient. Both types allow for scheduling that lets you save while you’re sleeping or away from home. Smart models add energy-saving features like energy monitoring, geofencing, and smart setback.

6. Humidity Control

Relative humidity (RH) reflects the amount of water vapor in the air within the context of temperature. In high humidity, your AC will be less efficient, and you’ll need a lower temperature to feel comfortable. You can improve cooling efficiency with a dehumidifier that lowers RH during summer. You can also improve heating efficiency with a humidifier that raises RH during winter.

7. Installation

Proper sizing is just one aspect of HVAC efficiency and why it’s so important to hire an experienced HVAC installer. Others include equipment placement, static air pressure, and adhering to the manufacturer’s specifications for the installation.

8. Maintenance

HVAC warranties typically require seasonal maintenance as a condition for coverage. Schedule in spring for your cooling system. Schedule again in fall for your heating system. This is good advice even if you have a heat pump that both cools and heats. Equipment gets dirty over time and becomes less efficient. It’s also necessary to tighten electrical connections, lubricate moving parts, and so on.

9. Static Air Pressure

Static air pressure is an important concept in HVAC performance. It refers to the resistance to airflow in the ducts. The blower is on the other end of the system moving the air. If air pressure is too high or too low, it will affect comfort throughout the entire home. It will also make the system work harder, which will decrease energy efficiency and increase your operating and long-term costs.

The main cause of static air pressure issues is a clogged HVAC filter. This is why you should check your filter at least every month and replace it as needed. During a seasonal tune-up, your technician will service your blower or air handler and check the static air pressure.

10. System Age

HVAC systems become less efficient with age. Routine maintenance and preventative repairs will slow the decline, but some deterioration is inevitable. There’s also the fact that new models are becoming more efficient each year. This is why it’s rarely economical to wait for an HVAC system to fail before replacing it. In fact, the DOE estimates that homes with older systems can save 20% or more annually with an upgrade.

11. Air Leakage

Air leakage refers to heating and cooling that seeps out of the seals in your ducts. The DOE estimates that air leakage causes heating and cooling losses of between 20% and 40%. To avoid this, schedule a yearly video camera inspection of your ducts. When the seals wear out, you can have the ducts resealed, which can lower your losses to 5% or less.

12. Zoning

Traditional central HVAC systems have a single zone, which is the entire home. A multi-zone system is a modern option through which we organize the home into multiple discrete zones. This requires additional equipment, such as a variable-speed blower and active duct dampers. Zoning makes an HVAC system more efficient because it allows you to adjust the temperature in each zone. You can, for instance, increase the AC in the zones you’re using and turn it down in those you’re not.

13. Air Balancing

In a balanced HVAC system, each vent or vent group is providing the right airflow for that particular room or area. With a traditional single-zone system, you generally only need air balancing performed during an installation or replacement. Zoned systems are more complex and sensitive. Experts recommend balancing every several years or so. An imbalanced zoned system will be less comfortable and cost more.

5 Health Risks Associated With Poor Indoor Air Quality

Written by Kevin on August 13, 2024. Posted in Indoor Air Quality.

Poor indoor air quality in a home is one of the most common triggers for a wide range of health problems. Even if there doesn’t seem to be direct visual evidence of a specific problem, such as dust or mold, you need to consider the possibility that particular health issues are tied to your home’s air quality. Here is a look at five common health risks linked to poor indoor air quality, the signs that they’re present, and how our HVAC technicians at Beltway Air Conditioning and Heating help customers address them.

1. Mold Growth

Mold naturally occurs in the air almost everywhere, but the high humidity levels in Maryland’s Prince George’s and Montgomery counties make it a notable regional problem. This is especially true during hot and humid summers that produce an ideal environment for mold growth. Mold can cause multiple respiratory health issues, including coughing, wheezing and congestion. Some folks also have skin reactions to mold.

Visible mold growth is the most obvious sign of a problem. It can appear as discoloration of walls and ceilings, particularly on white surfaces. You may also notice a musty odor, what people sometimes think of as a “basement smell.” Extreme mold issues can even lead to surfaces that feel mushy and have some give when you press on them, such as a soft spot in your home’s flooring.

Fortunately, HVAC upgrades are well-suited to addressing mold issues. A good dehumidification system can get the humidity level into the 30% to 50% range that’s best for your health. Likewise, installing an HVAC system that supports high-efficiency air filters can clean the breathable mold from the air that the dehumidifier might miss. Also, an efficient HVAC system should have a high-quality air intake that will ensure a supply of fresh and properly conditioned air in your house. The combination of those three solutions ensures clean, dry and filtered air.

2. Dust

Many people react to dust problems in their homes by sneezing. Other people experience a runny or itchy nose. Your eyes could be red and itchy, and they may also water. As with mold, people often have skin reactions. If anyone in your household has an existing respiratory issue, such as asthma or COPD, they may have worse symptoms when they’re in the house.

Dust often accumulates in a home. If you see it settling or a lot or have to clean it constantly, then there’s probably a dust problem. The issue is often most noticeable in the low-traffic parts of a house. Similarly, dust will usually be more present near air registers.

High-efficiency air filters are the main line of defense against dust. Also, a good duct cleaning can make a major difference. Make sure to schedule duct cleaning as needed to deal with the problem. Sealing the ductwork is also a good idea since dust often sneaks into the ducts through a home’s basement.

3. Volatile Organic Compounds

Chemicals are everywhere in modern life, and many pose indoor air quality issues. Volatile organic compounds (VOCs) can come from an almost endless list of everyday items, including cleaning products, paints, solvents, hairsprays and perfume. They can even come from things like new carpets, printers, cookware and glues. Some dry cleaning chemicals can even track into the home.

Most of the signs are VOCs in your home are health-related. Your household may experience headaches, nausea, dizziness and fatigue. Some people may also experience red and itchy eyes. Existing respiratory concerns are likely to worsen in the presence of VOCs.

The one non-health-related sign is a strong chemical smell. VOCs often smell industrial and gassy.

An HVAC system with a good air intake is critical to dealing with VOCs because fresh air is the best solution. Very high-efficiency filters are also optimal. HEPA filters rated MERV 13 or higher can catch most of the bigger particles released from VOC-generating products. In April 2024, Maryland passed legislation requiring a minimum of MERV 13 for residences in the state. You may also want to consider an activated carbon filter because the carbon can react with the chemicals. Notably, keeping humidity in that 30%-to-50% range can reduce some chemical reactivity.

You may also want to consider using a programmable thermostat to run the HVAC for longer cycles. This works best when you know what the source of the VOCs is, such as a recently installed carpet, a piece of furniture or a dried paint or stain.

4. Carbon Monoxide

Carbon monoxide is one of the rare cases where the HVAC system itself could be the culprit. CO can come from a furnace or other heating system that’s malfunctioning. This may happen if the system was poorly installed or has aged to the point of inefficiency. Other sources of CO in the home include gas ovens, water heaters, improperly installed generators and clothes dryers. Homes with fireplaces and chimneys are especially vulnerable to CO build-up.

The presence of carbon monoxide can trigger headaches, dizziness and nausea. However, the most extreme scenario could lead to someone passing out or even dying. Making CO even scarier is that there’s no way to see, smell or otherwise perceive its presence. Without installing a carbon monoxide detector, you won’t be sure if there’s a problem.

Even if the HVAC system in your house is brand new, have one of our technicians check it. Manufacturing and installation issues are rare, but they happen. If the HVAC system is old, that’s another reason to check it. You can ask our technicians to install a CO detector because it’s a cheap way to avoid a tragedy.

If your HVAC equipment isn’t the source of the problem, there are still some solutions. A high-efficiency HVAC system with a good air intake can provide more fresh air and dilute the CO level. Also, test the air pressure in your home’s registers, ducts and vents. If the air pressure isn’t balanced, you can get back pressure. For example, the air from the kitchen might flow into other rooms, raising the CO levels in them.

5. Air Pollution

Outdoor air pollution can become an indoor air quality issue. You may notice chemical or smoky smells, especially if the pollution originates from vehicle exhausts or a nearby factory. It is rare to see old-school sooty pollution, but it can occur in high-traffic areas, especially near intersections and highways.

The health signs tend to be coughing and wheezing. Throat irritation is very common. Eye and nose irritation can also happen. As with other chemically induced issues on this list, headaches and dizziness can occur.

High-efficiency air filtration is essential for treating pollution. Also, regular duct cleaning and HVAC maintenance will make a major difference. You want the ducts to be sealed tight, too, to prevent pollution uptake.

Understanding The Different Parts of Your HVAC System

Written by Kevin on August 6, 2024. Posted in HVAC.

Even though you rely heavily on your HVAC system to keep you comfortable throughout the year, you might not know all that much about how it works. That’s not unusual. Most homeowners’ knowledge of HVAC systems doesn’t go much beyond operating a thermostat. However, if a component of your Hanover, MD home’s HVAC fails, a bit more knowledge can go a long way toward getting you back on track. To help, here is a guide to the major components of your home’s HVAC system. We’ll identify each component and let you know exactly what it does. That way, you can approach future necessary HVAC repairs with confidence that you know what you’re talking about.

Thermostat

We’ll begin with the part of your HVAC that you’re most familiar with. Your thermostat is the device that keeps track of the temperature in your home. It also signals your HVAC system to turn on and off based on your comfort preferences. Your thermostat connects to your HVAC system via control wires. A basic thermostat will have at least four wires connecting it to your HVAC. More advanced thermostats, including smart thermostats, can have up to six wires.

You can think of your thermostat as the brain of your HVAC. The more advanced your thermostat, the more you can do with your HVAC system. Basic thermostats have little more than simple temperature sensing and on/off capabilities. Programmable thermostats make it possible to set automated temperature schedules by the day or hour. Smart thermostats feature advanced connectivity and learning capabilities to maximize HVAC efficiency and improve your comfort.

HVAC Indoor Unit

The parts contained inside your HVAC’s indoor unit vary depending on the type of system you have. For these purposes, we’ll assume you have a combination of a gas furnace and a central AC system. These are the parts you’ll find in the indoor unit of such a system.

Control Board

The control board inside your HVAC indoor unit receives signals from your thermostat and activates components as necessary. If you request heat, it will activate your furnace’s burners and blower motor to provide it. If you need cooling, your outdoor condenser unit and indoor unit blower motor will activate.

Blower Motor

The blower motor in your HVAC indoor unit draws in air through your home’s return air ducts. It pushes that air past the system’s heat exchanger or evaporator coil to heat or cool it as needed. Then, it pushes the conditioned air back through your home’s supply vents.

Combustion Chamber and Burners

The combustion chambers and burners inside your HVAC indoor unit are the main components of your furnace. Inside the combustion chamber, there’s a valve that controls the flow of natural gas into the burners. It ensures that there’s a proper mixture of gas and oxygen to support complete combustion inside the chamber. To ignite the combustion process, the burners typically rely either on a pilot light or a glow stick. The pilot light continuously burns a tiny amount of natural gas to serve as an ignition point. A glow stick uses electrical resistance to create enough heat to cause combustion of the gas and air mixture.

Heat Exchanger

Your heat exchanger is the part of your furnace that warms the air coming from the blower motor. It is like a radiator. The hot gasses resulting from the combustion process pass through sealed tubes within the heat exchanger. Those tubes have large sets of fins attached to them, which transmit the heat into the passing air. Then, the combustion gasses leave the heat exchanger to exit your home through the furnace’s flue.

Flue

Your furnace’s flue is a pipe that allows the furnace’s combustion gasses to leave your home safely. These gasses include substances like carbon monoxide, so proper ventilation is critical. Those combustion gasses also leave the heat exchanger at a high temperature. Furnace flues are typically made of aluminum, which can handle high heat without warping or suffering damage.

Evaporator Coil

When you’re running your HVAC in cooling mode, all the previously mentioned furnace parts stand idle. The only shared component that doesn’t is the blower motor, which runs in heating and cooling mode. However, in cooling mode, another type of heat exchanger called an evaporator coil goes to work. The evaporator coil receives cold refrigerant from your HVAC’s outdoor unit. As air passes over the coil, the cold refrigerant absorbs heat from the air to cool down your home. That causes the refrigerant to warm up and boil off into a gas before it leaves to return to the outdoor unit. The process of cooling the air also allows your evaporator to dehumidify the air through condensation. The collected water then drains from your indoor unit via a condensate drain line.

HVAC Outdoor Unit

Your HVAC outdoor unit is only active when you’re running your system in cooling mode. As a result, it has fewer parts than the indoor unit. Here’s what they are.

Compressor

As its name suggests, the compressor in your HVAC outdoor unit manipulates the pressure on the system’s refrigerant. Specifically, it increases the pressure on the warm gaseous refrigerant coming from the system’s evaporator coil. This raises the temperature of the refrigerant until it’s hotter than the outside air. That’s how your HVAC system can exhaust heat from your home even when it’s hot outside.

Condenser Coil

The majority of the space in your HVAC outdoor unit is occupied by a heat exchanger called a condenser coil. It’s where the hot, high-pressure refrigerant goes to release its heat into the outside air. To facilitate that, the condenser coil has a series of large fins to maximize contact with the outside air. The condenser coil gets its name from the process that happens inside it. As the hot gaseous refrigerant releases its heat, it condenses back into a liquid to begin the cooling process again.

Condenser Fan

A large fan called a condenser fan is typically situated at the top of your outdoor HVAC unit. Its job is to pull outdoor air through the fins of the condenser coil to cool the refrigerant inside it. The fan vents air straight up from the top of the unit.

Expansion Valve

After the cooled refrigerant condenses back into a liquid, it’s still too hot to help cool your home. That’s where your outdoor HVAC unit’s expansion valve comes into play. It reduces the pressure on the warm liquid refrigerant. This lowers the refrigerant’s temperature and its boiling point. At that point, it can travel back to your indoor unit to begin the cooling process again.

The Environmental Impact of Older HVAC Systems

Written by Kevin on July 19, 2024. Posted in HVAC.

If your Arbutus, MD, HVAC system uses inefficient technology, it could have a negative impact on the environment. Old age, an extensive maintenance history, low energy efficiency ratings, and outdated refrigerant types are key markers of an out-of-date HVAC system.

Energy Consumption: A Key Environmental Concern

Older systems often use more power since they aren’t as efficient at turning energy into warm or cold air. This raises emissions and exacerbates the greenhouse effect. Modern systems can save a lot of energy and reduce your household’s carbon footprint since they are up to 30% to 50% more efficient than older versions.

Older systems often fail to effectively keep interior temperatures steady, especially during extreme hot or cold weather periods. Consequently, this increases electricity consumption and strains power systems during peak hours since they need more energy to attain their targeted comfort levels.

Utility companies are often forced to expand their infrastructure to handle surges in demand. The expansion of infrastructure, particularly power plants that rely on fossil fuels, exacerbates the problem of environmental deterioration and greenhouse gas emissions.

Refrigerant Issues: Harmful Emissions

The environmental effect of refrigerants varies greatly among different types, even though they are essential for HVAC systems to maintain cool temperatures. R-22 (chlorodifluoromethane) and other refrigerants used in older HVAC systems have a high ozone-depleting potential and a considerable global warming potential.

Improper refrigerant disposal or leakage directly contributes to ozone depletion and greenhouse gas emissions. In recent years, R-22 has been banned. Newer and safer products are used in new air conditioning models. One of our HVAC experts can educate you on which kind of refrigerant your system uses and whether there are any safe alternatives. Upgrading to a more modern system will ensure the use of safer refrigerants.

Maintenance Challenges and Energy Efficiency Loss

Maintenance is essential to keep HVAC systems running at peak efficiency and performance. Problems, including clogged filters, worn-out parts, refrigerant leaks, and inappropriate airflow, are common in older systems because of poor maintenance practices. Because these problems result in HVAC systems working harder to reach desired temperatures, they directly affect energy efficiency. For instance, inefficient cooling or heating due to clogged filters increases energy costs. For example, when refrigerant escapes, it releases harmful compounds into the air, reducing the system’s cooling capability. This is why it’s crucial to schedule routine inspections, change filters regularly, and have interior coils, fan blades, and interior components cleaned on a regular basis. All these maintenance tasks help maintain energy efficiency, increase the system’s longevity, and decrease operating expenses.

Noise Pollution Effects on Indoor Environment

Older air conditioning systems, particularly ones with insufficient noise-reduction measures or older compressors, tend to make a lot of noise while they’re running. Noise pollution has several environmental repercussions, including disruptions to ecosystems and animal habitats.

Noise pollution also reduces people’s quality of life by interfering with their daily activities, increasing their risk of stress, insomnia, and other health problems. Using more modern HVAC equipment and incorporating sound insulation into your home’s design are two ways to lessen the impact of HVAC systems on your indoor environment.

Air Quality Concerns

Dust, mold, allergens, and volatile organic compounds are common indoor contaminants that can accumulate in your indoor air when older systems don’t have proper ventilation and filtering. These pollutants can circulate throughout the home, endangering the health and comfort of those who live or work there. Several health conditions, such as shortness of breath, allergies, headaches, and fatigue, are common side effects of poor indoor air quality.

Technology Solutions: Innovations in HVAC Systems

Homeowners now have exciting new options to improve indoor comfort, lower energy usage, and reduce the environmental effects of their HVAC systems. Variable refrigerant flow (VRF) systems are a notable invention. These systems differ from conventional HVAC systems in that they change the refrigerant flow rate in response to the unique cooling and heating demands of individual rooms or zones within a house. This tailored method increases comfort by keeping temperatures consistent throughout the home and increases energy efficiency by decreasing wasteful energy usage.

The incorporation of smart HVAC controls is another innovation. These systems use occupancy sensors and intelligent algorithms to automatically adjust the temperature according to the day, weather, and other factors. This allows homeowners to optimize energy consumption and comfort even when not at home by remotely controlling their HVAC systems using smartphones or tablets.

Compressor technology has also progressed to the point where high-efficiency compressors are available, which use less power without sacrificing performance. The dependable and silent operation of these compressors helps save energy and lessens their effect on the environment.

Another commonality among modern HVAC systems is the use of environmentally friendly refrigerants such as R-410A and R-32. Compared to R-22 and other older refrigerants, these refrigerants have a lower GWP, making them compliant with sustainability targets and environmental legislation.

Steps to Upgrade and Improve Environmental Impact

The first step in updating an older HVAC system to reduce environmental effects is getting a professional opinion. It’s best to hire HVAC experts to check your home’s energy efficiency and provide recommendations for modifications that fit your requirements and budget.

An HVAC expert can help with all the involved processes of updating your system. This includes performing an assessment and an energy audit. These tests make it possible to assess how well your present system works and help find ways to make it better, such as sealing leaks in ductwork.

Experts will also help with the selection of an energy-efficient system. Geothermal heat pumps and ductless mini-split systems are two forms of air conditioning that use the least amount of energy. Both types also provide heating.

Hiring our experts is also helpful when it comes time to remove the old system. Avoiding environmental damage and ensuring compliance with local legislation requires proper disposal of the old HVAC unit. We will conduct a thorough sizing test to determine your home’s specific heating and cooling requirements before installing a new unit. This will help the unit last longer and achieve maximum efficiency.

Once installed, our experts will update you on the latest maintenance requirements for the system. General maintenance for most newer systems typically includes changing air filters on a regular basis and scheduling professional maintenance at least once a year. Many experts also recommend checking the thermostat periodically to ensure its accuracy. If you don’t have one yet, you should consider upgrading to a programmable thermostat.

Why Air Ducts Should be Cleaned by a Professional

Written by Kevin on July 12, 2024. Posted in HVAC, Indoor Air Quality.

The air ducts in your Hanover, MD, home play an important role in keeping you and your loved ones comfortable. By circulating air from your heating and cooling system to the various rooms in your house, air ducts help ensure that the desired temperature of your living space remains consistent throughout. If neglected, air ducts can accumulate dust particles, mold, pollen, and various other types of debris. These pollutants building up in your air ducts can lead to a number of issues, making having your air ducts professionally cleaned highly beneficial.

Let’s look at the benefits of having your air ducts professionally cleaned.

Improving Air Quality

The air that circulates through your ducts is the air you and your family breathe daily. This indoor air contains potential contaminants, such as pet dander and dust, which get pulled into your HVAC system. Over time, there can be an accumulation of these pollutants in your ductwork that can re-enter the living areas of your home.

When you breathe in these contaminants, there is a greater likelihood of respiratory illness. You also run a greater risk of triggering allergies. Even if you or the other members of your household do not suffer from these issues, taking in lower-quality air can make breathing more difficult. It can also diminish the ability to focus and affect mood. Having your air ducts professionally cleaned helps to eliminate these harmful contaminants, improving your IAQ and health.

Boosting HVAC System Efficiency

If dust particles and other contaminants build up beyond a certain point in your ductwork, there is a likelihood that your airflow could be compromised. This leads to airflow inefficiency, causing hot and cold spots throughout your home. Your HVAC system winds up having to work harder to do its job of circulating enough warm or cool air for your household. This can be seen in your energy bill, which will get progressively higher. Keeping your air ducts clean allows for the free flow of air, maintains system efficiency, and prevents utility bills from needlessly increasing.

Eliminating Odors

Paint fumes, food, tobacco smoke, and various other smells can permeate a home. These odors can get trapped in your ductwork and be recycled through your home repeatedly. Awful smells can also occur from a buildup of mildew, mold, and bacteria in your ducts. There is also the potential for rodents or other vermin to either leave droppings in your air ducts or to get trapped and die. These types of smells do not go away by simply cracking a window or using an air freshener. Having your air ducts professionally cleaned helps to minimize the chance of bad odors in your household.

Keeping Your Home Safe

When dirt, lint, and other materials accumulate in your air ducts, a fire from them is possible to ignite. Not only can this cause immense damage to your property, but it also puts the lives of your family at risk. The risk of such an occurrence increases exponentially if you have an older HVAC system or if you utilize propane to power your stove, furnace, or fireplace. Having a professional regularly clean your air ducts helps to keep your home and family safe by minimizing the chance of a fire.

Extending the Lifespan of Your Unit

When your ductwork is dirty, your unit has to work harder. The strain on your system can cause wear and tear, potentially leaving you with a broken-down system that requires repair during an inconvenient time of the year. Continual use of a system that is overburdened can eventually tax the motor and compressor to the point that your HVAC system may need to be replaced altogether. By regularly having your air ducts cleaned, you can prolong the life of your system by years.

Making Air Filters Last Longer

The air filters in your HVAC system trap dirt and other contaminants. Should there be excessive amounts of these pollutants built up in your air ducts, your filters will get clogged faster than is typical. This means that you will have to have them replaced more often. This can become tedious, but by having your air ducts professionally cleaned, you can avoid having to switch out your air filters at such a rapid rate.

Why You Should Not DIY Cleaning Your Air Ducts

Doing DIY projects around the house can be fun, rewarding, and save you money. Cleaning your air ducts, however, is not the type of task that should be done on your own. First off, there is the issue of safety. A professional has been properly trained and certified to handle the task of cleaning your air ducts. They will also have the appropriate tools for the job. If you take on cleaning your air ducts, you run the risk of injury or worse by trying to do the job without the appropriate experience or tools.

There is also the matter of warranties. Some HVAC manufacturers do provide warranties that cover ductwork. You may also have coverage for ductwork in your home warranty. Warranties may cover things like normal wear and tear, replacement, or repairs. However, warranties are typically voided when there is clear neglect, or the maintenance that is performed is not professionally done. If you opt to do your air duct cleaning on your own, there is no guarantee that you will be covered should anything go wrong. That means you could be financially on the hook for any necessary repairs or replacements.

Another reason not to go the DIY route when it comes to cleaning your air ducts is that a trained technician may spot other important issues in your ducts. When a professional cleans your air ducts, they will also typically inspect the ducts for any loose connections, gaps, rust, or leaks. A technician will also insulate your air ducts, should it be necessary.

A professional who cleans your air ducts may identify problems that trace back to your HVAC system that you would not notice. Once these HVAC system issues are identified, a technician has the expertise to fix them. Trusting a professional to possess the knowledge and skill to spot and fix related issues while they are minor is a major reason not to DIY a project like this.
