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.

The Role of Air Filters in Enhancing Indoor Air Quality

Written by Kevin on June 15, 2024. Posted in Indoor Air Quality.

The quality of the air that we breathe in our Hanover, MD, homes is incredibly important. Since many of us spend so much time indoors, it makes sense that we should be prioritizing air filtration. Unfortunately, a house can experience contamination from several types of particulates and pathogens. This often results in headaches, more allergy symptoms, irritated nasal passageways, and inflammation. Luckily, there is room for improvement using air filters and air filtration technology. Let’s discuss your options.

What Contaminants Need to Concern You?

Before we talk about the different types of filters that are available, it’s important that you know what contaminants you may need to deal with. Your specific indoor air situation will determine what kind of filtration you need. These are some common indoor air quality issues you need to be aware of.

Pollen

In the spring and summer months, Hanover can experience high levels of pollen in the air. Even if you’re keeping your windows and doors closed, no home has a tight enough envelope that nothing will make its way inside. As you’re exposed to pollen, you may experience sneezing, itchy eyes, a scratchy throat, or a cough. If you also deal with asthma, seasonal allergens can increase your risk of attacks.

Volatile Organic Compounds

Volatile organic compounds (VOCs) come from a variety of products. These chemicals occur in cleaning products, beauty products, and building materials like countertops, cupboards, and furniture. You can also find them in air fresheners and scented candles. You can make some changes to the products you buy to ensure you’re using more natural items, but some VOCs can’t be completely avoided.

Pet Dander

Pets are a wonderful addition to a household, but they release dander that circulates throughout your home. If you are allergic, pet dander can make you sneeze, itch, and cough.

Dust

Even the cleanest homes have dust particles circulating in the air. If you’re using optimal filtration, it can cut back on dust particles. This not only keeps your home cleaner but also improves your indoor air quality.

The Importance of Air Filters

Air filters can trap and remove particulates from your indoor air as they move through your HVAC system. Filters often last 30 to 90 days, depending on the type of filter you’re using. How often you’ll need to change them will depend on how frequently your HVAC system is running, how often you open your windows and doors, whether you have pets, and other factors. Not only do filters help improve your indoor air quality, but they also protect your HVAC system.

Filters come with a MERV rating, which stands for minimum efficiency reporting value. The higher the MERV rating, the fewer particulates that can pass through that filter. While you may think it’s best to go right out and purchase the filter with the highest MERV rating, this isn’t the case. Filters with a high MERV rating must work with an HVAC system that is capable of passing air through the filter with ease. Otherwise, they will place strain on your system that may result in the need for more repairs.

HEPA Filters

High-efficiency particulate air (HEPA) filters can remove as much as 99.97% of the particles that are in your indoor air. This includes things like pet dander, pollen, dust, mold spores, and more. Typically made from plastic or fiberglass layers, HEPA filters often come in an air purification device that has been installed in your HVAC system. HEPA filtration is optimal because it can also reduce the number of viruses and bacteria that are in your home. It’s ideal in cold and flu season.

Fiberglass Filters

Fiberglass filters are very affordable, and they are the most frequently used filters in HVAC systems. Made from strands of fiberglass, these filters generally have a very low MERV rating. In many cases, they have a MERV rating as low as 2 or 3. They are effective along with some other types of air filtration, especially with regular filter changes.

Pleated Air Filters

With a fan-like design, pleated air filters come in a range of efficiencies. Most will last for 30 to 90 days. They are usually made from paper, fiberglass, or cloth. The MERV rating of a pleated air filter can range from 3 or 4 up to 13. To choose the right filter, you need to take into consideration the type of HVAC system that you have. If you don’t have an HVAC system that can handle a high MERV filter, you may need to consider an upgrade. Adding a whole-home purification unit to your setup can also be beneficial if you’re not able to trap enough contaminants with your filter alone.

Electrostatic Filters

By using electricity to capture particles, electrostatic filters can remove particles that are as small as 0.1 microns in size. The filter is charged, while particulates are charged oppositely. This allows for particle removal before air circulates through the home. This is an affordable filter option, as many units utilize electronically charged plates over a replaceable filter. You simply clean the plates and place them back in the unit.

Washable Filters

For homeowners who are looking to reduce their carbon footprint and save some money, there are reusable filters to consider. They look like a disposable filter option, but you remove the filter, rinse it off, and replace it once it has dried. You’ll likely want to have a couple of these filters on hand so that you can still run your HVAC system while one filter is drying. Placing a filter back into your system before it is completely dry and ready can result in mold growth. Some people question if a washable filter ever really gets completely clean. While they can be quite effective, you might prefer a disposable option if you suffer from severe allergies.

Filter-Free Options

In addition to utilizing a filter in your HVAC system, there are other options that work in tandem with your filter setup. This will enhance filtration, so you will experience even better indoor air quality. UV-light technology is available. As things like mold spores, bacteria, and pathogens pass over the light, which is on the UV-C spectrum, they will be broken down. Cleaner and healthier air will pass back into your home through your HVAC system. Another option is using a dehumidifier. When you remove excessive moisture from your indoor air, fewer particles will be present. This also inhibits the growth of mold spores and increases overall comfort in your home.

If you would like to learn more about the different filters that are available for your Hanover home, reach out to the team at Beltway Air Conditioning and Heating. We are ready to help you achieve and maintain a healthy indoor air quality level. We can also help with the installation, repair, and maintenance of your heating and cooling equipment. We offer whole-home dehumidifiers and humidifiers, plumbing services, and thermostat installation, too.

The Meaning Behind HVAC Efficiency Ratings

Written by Kevin on June 10, 2024. Posted in HVAC.

HVAC efficiency ratings are an invaluable tool for homeowners purchasing a new system. This information informs you how environmentally friendly a system is and how much it will cost to run over its lifespan. Use that information to compare any system to another and make a better buying decision. With this in mind, let’s explore the different rating systems you may encounter.

BTU

The British thermal unit (BTU) is a measure of energy and heat in particular. While it isn’t a measure of energy efficiency, it’s an important concept in the HVAC space. Many of the energy efficiency ratings we’ll discuss here use BTUs in their equations or as a criterion.

One BTU represents the amount of energy required to raise the temperature of one pound of water by one degree Fahrenheit. A BTU is equal to about 1,055 joules. As a general rule when sizing an air conditioner, you need 20 BTUs per square foot. Most central ACs and mini-split systems in the U.S. are 45,000 BTU units. Most furnaces are within the 80,000 to 100,000 BTU range.

SEER

The seasonal energy efficiency ratio (SEER) measures cooling efficiency over an entire theoretical cooling season. Manufacturers test their ACs and heat pumps in a laboratory setting. They then divide the BTUs of heat removed from the air by the total energy in watt-hours required.

What the consumer should know is that the higher the SEER, the cheaper the AC or heat pump is to run. It’s also important to know that the Department of Energy (DOE) sets minimums on a regional basis. There are three regions in the U.S. for the purposes of energy efficiency ratings: North, South and Southeast. As of 2023, the minimum SEER is 14 in the North, and 15 in the South and Southeast.

There are systems with SEER ratings well above the minimums. When the new minimums went into effect in 2023, there were central ACs with SEER ratings in the 20s. There were also mini-splits with SEER ratings in the 30s. Whether a higher SEER is worthwhile is a matter of comparing the added initial cost to the long-term savings.

SEER 10 was the minimum when the DOE introduced the concept of energy efficiency minimums in 1992. If you currently have a SEER 10 AC and upgrade to a SEER 14 AC, you would reduce your electricity consumption by 28%.

HSPF

Heating seasonal performance factor (HSPF) is similar conceptually to SEER. The fundamental difference is that it measures heating efficiency rather than cooling efficiency. HSPF is relevant specifically to heat pumps. Heat pumps are similar to ACs but have a reversing valve that lets them provide heating too. Furnaces generate heat directly. Heat pumps transfer heat energy.

The minimum HSPF set by the DOE as of 2023 is 8.8, which is quite a bit less than the minimum SEER. Current air-source heat pump technologies are less efficient heating than they are cooling. This is because they use heat energy in the ambient air. In the summer, heat energy is abundant. In the winter, it’s not. Ground-source or geothermal heat pumps offer HSPF ratings comparable to their SEER ratings. This is because the earth is abundant with heat energy even in the winter.

SEER2 and HSPF2

In 2023, the DOE introduced SEER2 and HSPF2 as new versions of the SEER and HSPF rating systems. The main difference is that they now factor in the static air pressure of the air handler. This provides consumers a more accurate energy efficiency rating for ducted systems, such as central ACs. The minimum SEER2 is 13.4 in the North and 14.3 elsewhere. The minimum HSPF2 is 7.5.

Starting in 2023, all new ACs and heat pumps must have a SEER2 and HSPF2 rating available to consumers. This is in addition to the required SEER and HSPF ratings. Note that you cannot compare SEER to SEER2 and HSPF to HSPF2. At a currently undetermined time in the future, the DOE will deprecate the old rating system.

AFUE

Annual fuel utilization efficiency (AFUE) measures the energy consumption efficiency of furnaces and boilers. An 80 AFUE furnace converts 80% of the fuel it burns into heat. It wastes the other 20% as a byproduct. The minimum AFUE as of 2023 for all three regions is 81. You also have the option of a high-efficiency furnace or boiler. These are also known as condensing furnaces and boilers. They reclaim heat energy from their exhaust. This allows for an AFUE of at least 90% and as high as 98.5%.

Electric furnaces have an AFUE of 100%, but this is a bit misleading. It’s true that they’re more efficient in that they lose no energy in the production of heat. That said, it’s an apples to oranges comparison. Electric furnaces are much more expensive to run.

EER and CEER

Energy efficiency ratio (EER) measures cooling efficiency. The difference between EER and SEER is that EER measures peak efficiency at 95 degrees Fahrenheit. SEER is much more informative to the average consumer choosing a central AC or heat pump. It just doesn’t stay hot enough long enough in the U.S. for EER to be relevant to consumers. That isn’t the case when it comes to window ACs and other room-based ACs. In those cases, EER is a good measure of your long-term costs.

The DOE introduced combined energy efficiency ratio (CEER) in 2014. It measures the cooling efficiency of window and other room-based ACs. The difference between CEER and EER is that CEER also accounts for the efficiency of the unit in standby mode. That means that CEER is more valuable to the average consumer than EER.

COP and SCOP

Coefficient of performance (COP) is measure of cooling and heating performance. It applies to ACs and heat pumps. The higher the COP, the better the efficiency and the lower the cooling costs. COP is similar to EER. Seasonal coefficient of performance (SCOP) is similar to SEER and HSPF. It accounts for efficiency over a season rather than at a peak. These ratings are not commonly used in the U.S. The DOE does maintain COP and SCOP data because many other countries do use them.

ENERGY STAR

ENERGY STAR is a program run by the DOE and Environmental Protection Agency (EPA). The EPA awards ENERGY STAR certification to appliances that meet certain energy consumption criteria. If a heating or cooling system has the ENERGY STAR label, you know that it’s a high performer in this regard. It can also make you eligible for federal tax credits and rebates and local and private rebates.

Bright Solutions: 10 Benefits of UV Lights in Air Purification

Written by Kevin on June 1, 2024. Posted in Indoor Air Quality.

As homeowners and business owners look for better ways to clean and purify indoor air, the role of ultraviolet light (UV light) has come into play. These powerful lights are not only wonderful for illuminating spaces, but they can also help eliminate harmful pollutants and bacteria from the air we breathe. At Beltway Air Conditioning and Heating in Hanover, MD, we are committed to helping our clients improve their IAQ with unique, custom solutions, and we love incorporating UV lights because of their myriad benefits. Let us look at the top 10 benefits of UV light in air purification to improve indoor air quality.

1. Bacteria and Virus Elimination

UV lights eliminate bacteria and viruses by disrupting their DNA, making it impossible for them to replicate or cause infection. When the air contains bacteria or viruses and passes through a UV purification system, the ultraviolet rays deactivate the ability of the cells to reproduce, meaning that all the air circulating indoors is sanitized. UV systems can limit the risk of illnesses moving through the air and keep everyone in your home healthier.

2. Mold Prevention

UV lights play an important role in preventing mold by inhibiting the growth of mold spores. When UV lights are installed in HVAC systems or air purifiers, the UV light can target tiny airborne mold particulates and neutralize them. Neutralizing these tiny particles keeps them from landing on surfaces and multiplying. UV radiation prevents mold spores from reproducing and sanitizes the air, which helps people who suffer from allergies, respiratory problems, fungal infections, and general colds.

3. Allergen Reduction

UV lights can help reduce allergens by targeting common allergens such as dust mites, pet dander, pollen, and other contaminants. When we install UV lights in air purification systems, the UV lights can break down the DNA of these allergens and make them inactive so they cannot trigger homeowner’s allergic reactions. Eliminating air allergens means you will have a cleaner and healthier indoor environment. This is particularly important for allergy sufferers more prone to sneezing, congestion, coughing, and skin irritation. Improving your indoor air quality will improve the well-being of everyone living in your household, with or without allergies.

4. Odor Control

Say goodbye to gross odors and hello to fresh, clean air with UV lights. When added to your HVAC system, UV lights can help control funky smells that linger throughout your house. Whether it is a musty smell from the basement or leftover cooking smells in the kitchen, UV lights can neutralize those odors and keep your space fresh and clean. UV lights are particularly effective at neutralizing odors because they tackle the problem at the source — the air. Freshly cleaned air will give your home a clean, comfortable feeling that you will enjoy.

5. Improved Respiratory Health

UV lights protect your respiratory health by removing harmful viruses, bacteria, and allergens. UV lights will create a cleaner and healthier environment for you and your loved ones to breathe in. You can forget about sneezing fits, itchy eyes, stuffy noses, itchy skin, and other breathing problems when you add UV lights to your home’s HVAC system. We will walk you through how UV lights can protect your respiratory health and the custom installation options available.

6. HVAC Efficiency Improved

HVAC systems see a marked improvement in efficiency when UV lights are added.

At Beltway Air Conditioning and Heating, we offer custom HVAC solutions that maximize the impact of UV lights for your home.

7. Cost Savings

UV light systems keep your air clean and help you save some cash along the way. UV lights reduce the need for expensive filters and frequent maintenance by zapping away airborne germs and allergens. Plus, they are energy-efficient, so you will see your electricity bills fall. With UV lights in your house, you can breathe easier knowing that you are not only getting cleaner, fresher air but also protecting your wallet.

8. Eco-Friendly

UV lights are like little environmental warriors that battle airborne bacteria and pollutants without releasing any harmful chemicals or byproducts. That means you can breathe easy, knowing you are not harming the planet while you clean your indoor air. The lower carbon footprint leads to decreased greenhouse gas emissions. Plus, UV lights have a long lifespan, so you will not need to worry about replacing them and adding to landfills constantly. They are a sustainable choice for keeping your home healthy and green. You will also find that you need to use fewer chemicals in your house to clean because you will have fewer harmful microorganisms present. This makes it possible to focus on a greener cleaning approach using more natural cleaners without harsh chemicals.

9. Long-Term Health Benefits

UV lights in air purification systems are like superheroes for your health. They work tirelessly to zap away all the nasty bacteria, viruses, mold, and allergens floating around in your indoor air. By doing this, they help keep you and your loved ones safe from respiratory infections, asthma flare-ups, and allergies. Over time, having UV lights in your air purifier can make a big difference in your overall health and well-being. It is like having an extra layer of protection against everything that can make you sick. Investing in UV air purification is not just about cleaning your air; it is also about investing in a healthier future for yourself and your family.

10. Peace of Mind and Stress Reduction

Knowing that everyone you love is safe when they visit your home provides peace of mind and reduces stress. UV lights in air purification systems add an extra layer of protection against indoor air pollutants and harmful bacteria. You will feel an added sense of security, especially during flu season, when UV lights work to zap allergens and harmful pollutants from your home. Minimizing your risk of exposure to harmful microorganisms, UV lights will help you to feel more comfortable and relaxed in your surroundings, which will also lead to a healthier and happier living or working environment.

10 Signs Your Air Ducts Need Immediate Attention

Written by Kevin on May 20, 2024. Posted in Indoor Air Quality.

Your home’s air ducts play a critical role in circulating air throughout your home and are an important part of your home’s indoor air quality as well as the efficiency of your HVAC system. From visible mold growth and unpleasant odors to uneven heating and cooling, understanding the top signs that your air ducts need immediate attention will help you take care of both your HVAC unit and your health.

If you notice any of the following top 10 signs, we recommend addressing the problem quickly with a professional HVAC team. Restoring your HVAC unit and fixing any problems will improve indoor air quality and the efficiency of your HVAC system and benefit everyone who lives in your home.

Sign #1: Visible Mold Growth

If you see visible mold growth in your air ducts, it’s a sign that your HVAC unit requires immediate attention. Mold spores can circulate throughout your home via the HVAC system, potentially causing respiratory issues and other health problems. Addressing mold growth quickly is critical to prevent the spread and potential health risks for you and your family. A professional HVAC inspection and remediation are necessary to remove the mold from your air ducts.

Sign #2: Musty or Moldy Smells Coming From The Vents

If you notice musty or moldy smells coming from your vents, you may have a mold or mildew growth problem. Even if you cannot see any mold, the musty smell is a telltale sign of moisture buildup and condensation. Where there is moisture accumulation, there is the potential for mold. Ignoring these odors can lead to poor indoor air quality and create potential health risks for everyone who lives in your home. These health risks can be particularly damaging if you suffer from respiratory issues or allergies.

Sign #3: Dust Everywhere

Excessive dust accumulation throughout your home can be a sign of issues with your HVAC system or with your air ducts. Dust particles can circulate through the ductwork and settle on surfaces, requiring extra cleaning in order to keep spaces dust-free. Too much dust can also decrease indoor air quality. To fix the excess dust issue, it’s important to have an HVAC technician address the root cause of the problem. Too much dust could be a result of dirty air filters, poor ventilation and filtration, leaky ducts, or various other reasons. A thorough cleaning of the air ducts, as well as looking for the underlying issue to repair, is the recommended next step for homeowners who notice too much dust in their homes.

Sign #4: Rising Energy Bills

Higher energy bills could mean that there are issues with your HVAC system or your air ducts. If your system has leaks in the ductwork or a malfunctioning thermostat then the system might have to work harder in order to reach your desired temperature. Working harder can lead to higher energy costs and can put a strain on your finances. The best way to resolve both your higher energy bills and your malfunctioning HVAC unit is to repair the unit.

Sign #5: Pests, Pests, and More Pests

Are you seeing signs of a possible pest infestation around your home? If you see signs of pests around your home or around your HVAC unit, then you may have a pest infestation in your unit. Pests like rodents, insects, or even small animals sometimes use ductwork as a pathway to move around homes. As these pests move through your ductwork, they tend to create tears and leave droppings, as well as dander, behind. Pests can damage your HVAC system and negatively affect your indoor air quality. It is important to bring out pest control professionals to eradicate the infestation and HVAC technicians to fix any damaged ductwork.

Sign #6: Bad Allergy Symptoms and Respiratory Problems

Experiencing ongoing allergy symptoms and respiratory issues might mean that you have poor indoor air quality, which could be due to your ductwork. Dust, pet dander, bacteria, mold, mildew, and other airborne allergens can move through ductwork and exacerbate allergies and respiratory conditions. If you’re experiencing symptoms such as sneezing, coughing, congestion, and wheezing, and these symptoms are increasing, your indoor air quality might be poor. Bringing HVAC technicians to your home can fix your indoor air quality by cleaning and repairing the air ducts.

Sign #7: Strange Noises Coming From the Ducts

Do you hear strange noises such as banging, rattling, whistling, or popping sounds coming from your HVAC system? If so, then you may have damage to your system. Investigating and addressing the source of the noises in your HVAC system can prevent additional damage and repair the existing damage. Contacting an HVAC professional to diagnose and repair the issue will restore peace and quiet to your home as well.

Sign #8: Dents, Holes, or Disconnected Ductwork

Dents, holes, and disconnected sections in your ductwork can significantly impact the efficiency of your HVAC system. These issues can lead to a whole host of problems, including air leaks, causing heated or cooled air to escape into unused spaces and leading to energy wastage. They can also allow contaminants such as dust, pests, debris, and allergens to enter the ductwork and ruin your indoor air quality. Regular inspection and maintenance of ductwork can help prevent these issues from occurring and maintain a healthy indoor environment.

Sign #9: Insulation Damage

Insulation damage within your HVAC system should be rectified immediately. Damage leads to energy loss and will allow heated and cooled air to escape. Compromised insulation can also lead to condensation buildup, which promotes mold and mildew growth. HVAC technicians can address insulation damage by repairing and replacing the affected sections of your system.

Sign #10: Limited Airflow From Your HVAC System

Limited airflow from your HVAC system can be a result of several issues, all of which require prompt attention. Limited airflow places a greater strain on your system and can burn out mechanical parts if not fixed quickly. The limited airflow can typically be fixed with regular maintenance, including filter changes and duct cleaning. HVAC technicians will search your unit for the root causes of the limited airflow and fix those issues during their inspection.

The Science Behind Indoor Air Quality

Written by Kevin on May 17, 2024. Posted in HVAC.

The Science Advisory Board of the EPA ranks indoor air pollution as a top-five environmental risk to public health. Americans spend about 90% of their time indoors, and indoor pollutant and contaminant levels are rising. Let’s explore what you should know about indoor pollution and how you can achieve healthier indoor air quality (IAQ).

Ventilation

Ventilation in homes is a key reason poor IAQ is becoming a bigger problem. Modern construction techniques allow for houses that are significantly more energy efficient. The downside to that approach is little to no natural ventilation. Most homes rely entirely on passive ventilation. Pollutants get in, but the system doesn’t vent them out at the same rate, which causes concentration levels to rise.

Large Particulate Matter

Large particulate matter (PM) consists of particles that are bigger than 2.5 microns in size and smaller than 10 microns. Often abbreviated PM10, these are the particles you associate with allergies and asthma. This includes pollen, pet dander, dust, mold spores, dust mites, and so forth. PM10 may not have direct long-term health risks, but high levels will make you feel worse in the short term.

Fine Particulate Matter

Fine particulate matter or PM2.5 is a long-term health concern. This is the aspect of air pollution that modern science links to many cardiovascular and respiratory diseases and possibly certain cancers. Most PM2.5 in your home gets there due to outdoor air pollution sources. Monitor the air quality index (AQI) for your area. On days when the AQI is at an unhealthy level, avoid natural ventilation such as open windows.

Gases and Chemicals

There are potentially many gases and airborne chemicals in your home that can affect your health. If you have fuel-burning appliances, then carbon monoxide (CO) is the most notable. Radon is the second leading cause of cancer in the U.S. only behind smoking. It can seep into your home over time. The EPA recommends testing for it every two years or after any major home renovation. Other top concerns include formaldehyde and volatile organic compounds (VOCs).

Bacteria and Viruses

The presence of some pathogens in your home is unavoidable. That said, poor IAQ can foster an environment in which the levels of bacteria and viruses are higher. In addition, poor IAQ can make you more prone to the development of infection from those viruses and bacteria.

Humidity

Humidity is the amount of water vapor in the air. Relative humidity (RH) is a measure of humidity within the context of temperature. RH plays a role in IAQ in a number of ways. If RH is too high or too low, it’s more difficult to breath, and you’re more prone to irritation. Additionally, when the RH is higher, there are more pollutants in the air due to the higher level of water molecules.

How to Maintain Healthy IAQ

The good news is that there are many solutions available to help you improve IAQ and maintain it. Here are some of the strategies that our IAQ experts recommend as the most important.

Source Control

Dust is by far the top issue when it comes to poor IAQ. It’s more than just PM10. Dust is effectively a sponge that absorbs gases and chemicals, extends their effective life spans, and emits them over time. For this reason, the EPA recommends a deep dusting of your home at least once a week.

You should also be careful not to introduce pollutants and contaminants into the home. Avoid household cleaners that contain toxic substances. Store potentially harmful substances outside the home. Avoid furniture and other items that off-gas VOCs.

Air Quality Testing

The first step we recommend is scheduling an IAQ test with us. We’ll perform comprehensive IAQ testing, including for radon, and provide you with a breakdown. Armed with this information, you’ll understand your IAQ challenges and how best to use your home improvement budget.

Seasonal HVAC Maintenance

Schedule us for a cooling tune-up in spring and a heating tune-up in fall. Doing so will save you money over the long term. It will also help you maintain good IAQ because we’ll clean all of your equipment. An HVAC system coupled with high dust levels is a main contributor to poor IAQ.

Air Filtration

Air filtration is a powerful tool in the battle against PM. If you have a central HVAC system, you have integrated filtration via your HVAC filter. The minimum efficiency reporting value (MERV) rating measures filter efficiency. The EPA recommends choosing an HVAC filter rated MERV 13. Most modern HVAC systems can support this value, and it will help trap most PM10 and PM2.5.

You can also add more mechanical filtration via a high-efficiency particulate air (HEPA) filter. HEPA filters restrict airflow too much to be on the supply side of your HVAC system. You can benefit from them through portable and room air purifiers and a duct-installed HEPA filtration system.

Duct Cleaning

At least every several years, you should schedule us for duct cleaning alongside a seasonal tune-up. No matter how much you dust, some of it will accumulate in your ducts where it’s impossible for the homeowner to reach. Our team has the equipment to extract all that dust and remove it from your home.

Air Purification

Our IAQ team also installs indoor air purifications systems. Supply-side air purifiers have activated carbon that neutralizes odors, VOCs, and many other gases and chemicals. You can also opt for an air purifier with a UV stage or UV lamps in your ducts. UV neutralizes bacteria, viruses, and more.

Humidifiers and Dehumidifiers

Whole-home humidification and dehumidification systems let you control your residence’s RH. A humidifier is most helpful in winter when the air is drier. A dehumidifier is most helpful in summer when the air is moist. This is also when your home is most prone to mold and dust mites. Both humidifiers and dehumidifiers can help to improve energy efficiency of your HVAC system as well.

Carbon Monoxide Monitors

If you have any fuel-burning appliances, it’s imperative to protect your family with one or more CO detectors. The coverage you need depends on the number and scope of appliances.

Whole-House Fans

If your home does not have enough ventilation, a whole-house fan is the solution. Such fans can introduce fresh air. Heat and energy recovery ventilators (HRV, ERV) are an option as well. These are more advanced whole-house fans that can improve energy efficiency. An ERV may also offset the need for a humidifier.

The Importance of Seasonal HVAC Maintenance

Written by Kevin on May 10, 2024. Posted in Uncategorized.

Your HVAC system is a vital part of your home. It provides comfort and protection from extreme outdoor temperatures, especially in the summer and winter. Unfortunately, too many people neglect regular maintenance of their heating and air conditioning systems until something goes wrong. This piece will explore the importance of seasonal HVAC maintenance and the benefits that come with it.

Improved Home Comfort

If an HVAC system isn’t maintained regularly, it can decrease its ability to warm or cool your home, especially in the months with the most extreme weather. If your refrigerant level is low, this can significantly reduce your AC’s ability to keep you cool in the summer. If your ducts or blower vents are clogged up, it will affect airflow, which can result in unwanted warm or cold spots in parts of your home.

HVAC Life Span Extension

With seasonal maintenance, a technician will be able to find minor problems before they get worse and become major issues. Because minor problems are caught and remedied early, less strain is put on components, and it greatly increases the life span of your HVAC system. Lubrication can be added to moving parts to reduce the wear and tear of friction. Electrical wiring can be checked to ensure there aren’t any issues.

Operational Safety

When HVAC maintenance is neglected, there are safety hazards that can occur. When a technician is performing maintenance on your HVAC system, they can identify and fix electrical issues that are a fire hazard. Water leaks can cause structural damage to your home, especially if they aren’t noticed for some time. If you have a split HVAC system that burns natural gas in the heating process, a technician can check for natural gas or carbon monoxide leaks.

Lower Energy Bills

One of the best reasons that it’s good to invest in seasonal maintenance of your HVAC system is that it can actually save you money. When your HVAC gets regular cleaning and maintenance, your system runs much more efficiently. This can dramatically lower your energy bills when compared to an HVAC system where homeowners have neglected the required maintenance. During a particularly hot summer or cold winter when your HVAC system is working harder, the savings due to improved efficiency can be even more noticeable.

Air Quality Improvement

You should be regularly replacing or cleaning your air filters. However, when a technician comes for seasonal maintenance, they can do that for you and a lot more. Over time, your system begins to accumulate contaminants like:

Pollen
Dust
Mold spores

When blown into the home, these pollutants can be irritating to breathe, especially to people who regularly have respiratory issues like asthma or seasonal allergies. Professional cleaning can remove all these contaminants from your ductwork, vents, blowers, and other areas of your HVAC system if it is a serious issue.

Noise Reduction

An HVAC system can get noisy when it isn’t maintained properly. This can be for several reasons. The system may have to work harder to make up for the lack of efficiency. It can also be due to damaged components or debris making its way into the system. Depending on how noisy your HVAC gets when it isn’t maintained regularly, it can prevent your home from feeling like a peaceful environment. Additionally, occupants in bedrooms near a clunky outdoor unit may have trouble sleeping. When a technician performs seasonal maintenance, they can tighten components that have come loose or properly lubricate moving parts to fix the noise issue.

Humidity Level Management

Excess moisture in the air during the summer months can make the temperature feel hotter than it actually is. The humidity can also cause your skin to get uncomfortably clammy. To make up for the humidity, most homeowners turn their cool air up even higher, increasing their energy bill and putting stress on the HVAC system. Seasonal maintenance can result in reduced humidity in your home. Technicians can ensure your HVAC system is working optimally to remove excess moisture from the interior of your home.

Costly Repair Prevention

Getting seasonal maintenance keeps your system running smoothly and reduces the amount of stress that is put on components. By reducing this system stress, you are ensuring repairs aren’t needed as frequently. Additionally, if an issue is found on a system that gets seasonal maintenance, it is more likely to be minor, reducing the cost to fix it.

Protect Property Value

Whether you are looking to put your house up for sale on the market or you want to refinance the mortgage on your home, protecting the value of your home is essential. Since your HVAC system is such a vital part of your home, taking care of it with regular maintenance helps preserve your home’s property value. If potential buyers see that the HVAC is poorly maintained, they may decide that they need to replace it, and that expected cost will be reflected in a lower offer. Some potential buyers might choose to purchase another house altogether simply because they don’t want to deal with the issue.

Good for the Environment

Due to the better energy efficiency that comes with a well-maintained HVAC system, you’re also lowering your home’s carbon footprint and helping the environment. Additionally, many old HVAC units use Freon as a refrigerant. Freon is slowly being phased out and replaced by other refrigerants because it is harmful. If your HVAC system starts to leak Freon due to neglected maintenance, this harmful gas is directly polluting your local environment.

Comply With Warranty Conditions

If your HVAC system is still under warranty, there are likely terms and conditions that state the required maintenance of your system for the warranty to remain valid. If you ignore regular maintenance, your warranty claim may be denied. The same can be said about your homeowner’s insurance. If something happens to your HVAC system that causes damage to your home, an insurance company can decide that they won’t cover the damages because it was due to negligence of your HVAC system maintenance.

Peace of Mind

Lastly, taking care of regular HVAC maintenance gives you peace of mind. You don’t have to worry about the stress that comes with your unit breaking down or the anxiety that you may feel from higher energy bills.

Clearly, scheduling seasonal HVAC maintenance is essential for a variety of reasons. Efficiency, safety, comfort, and more are all affected by the state of your HVAC system. Schedule your next seasonal maintenance soon so you can enjoy all of the benefits that come with it.
