Reasons Your AC is Freezing Up and What to Do

Written by Kevin on March 1, 2024. Posted in HVAC.

Are you experiencing issues with your air conditioning system frequently freezing up? A frozen AC can be a serious issue since it has the potential to cause extreme damage, so it’s not a problem you should ever ignore. Luckily, there are only a handful of issues that can cause an AC to start freezing up, and some of them are things you can overcome yourself.

What to Do If You Suspect Your AC Is Frozen

A frozen AC system is an easy issue to spot. When the evaporator coil freezes and gets coated with ice, the system will no longer be able to remove heat from your home. This means that the temperature in your house will quickly start increasing. The air coming out of your vents will also be hot since all the system can do is circulate hot air when it is frozen.

If your AC does freeze up, you should always shut it off immediately. Allowing the system to continue running when frozen puts the compressor motor in the outdoor condenser unit at high risk of seizing or burning out.

When an AC functions normally, the refrigerant captures enough heat that it naturally changes from a liquid into a gas as it moves through the evaporator coil and gets pumped back outside. When the system freezes up, it leads to the refrigerant remaining in a liquid state. If liquid refrigerant enters the compressor, it can quickly boil and cause some of the oil that lubricates the compressor motor to burn off. This can then lead to the motor not being properly lubricated, which can cause it to burn out.

A burnt-out compressor motor is an extremely expensive issue to repair and can potentially cost about as much as installing a whole new condenser unit. That’s why it’s important that you shut the system off immediately if it freezes to prevent damaging it. Depending on what caused the system to freeze, it may be something you can quickly fix on your own. All of the following issues are really the only things that can cause an AC to freeze, so it is worth checking a few things before calling in the help of an AC technician.

Clogged Air Filter

A clogged air filter is by far the most common issue that will lead to an air conditioning system freezing up so it is always the first thing to check for. The issue is that a clogged filter greatly restricts how much warm air can be drawn into the system. The refrigerant in the system is extremely cold when it first enters the evaporator coil and then quickly starts warming up as it captures heat from the air. The problem is that a dirty, clogged air filter will massively reduce the amount of warm air coming into the system and moving across the evaporator coil. If there isn’t enough warm air continually flowing across the coil, the refrigerant will stay cold enough that all of the condensation on the coil starts freezing.

AC manufacturers generally recommend replacing the air filter in your system every three months. However, there are often times when the filter will start clogging up more quickly and need to be replaced sooner. This is why we recommend taking out the filter and inspecting its condition every month. As soon as the filter starts getting darker colored, it is time to replace it.

If your AC freezes up and the filter is quite dirty, replacing it will often solve the problem and prevent it from freezing up again. However, you need to wait at least an hour or two to make sure that the evaporator coil completely thaws before trying to turn the system on again. If the system does end up freezing again after replacing the filter, you’ll want to leave it shut off until you can have a technician inspect it.

Closed or Obstructed Vents

The other thing you should check if your AC freezes up is that all of the supply and return air vents are fully open and not clogged with debris or blocked by furniture or other items. The return vents are where warm air is drawn into the system. Although these vents generally can’t be closed, they will prevent enough warm air from coming into the system if they are clogged or obstructed.

The supply vents are where all of the cool air from the system flows out. To work properly, the majority of the supply vents in a home need to be fully open. Having one or two closed vents typically isn’t a problem, but any more than that can lead to the system freezing up. The issue is that when too many supply vents are closed or obstructed, lots of air gets trapped inside the ducts, which leads to the pressure increasing. When working properly, an AC system is constantly drawing in and blowing out the same volume of air. When the air starts to back up in the supply ducts and the pressure increases, it makes it much more difficult for the blower to bring sufficient air back in and can lead to the evaporator coil freezing.

Dirty Evaporator Coil

A dirty evaporator coil is another common culprit that can cause an AC to freeze up. Some dust and dirt always end up collecting on the evaporator coil over time, which is why the coil always needs to be cleaned every year as part of a preventative AC maintenance service. If the coil isn’t cleaned regularly, so much dust can build up that it effectively insulates or shields the coil. This means that the warm air coming into the system can’t come into direct contact with the coil, which greatly reduces how much heat the refrigerant can absorb. Again, if the refrigerant isn’t capturing sufficient heat, it may stay cold enough that condensation on the coil begins freezing.

This is an issue that you will need to have a technician check for and fix. Trying to clean the coil yourself is always a bad idea since you could easily damage it and cause a refrigerant leak or make the system far less effective.

Dirty or Malfunctioning Blower

The blower or fan also needs to be cleaned regularly since it also collects lots of dust. When the blower gets too dirty, it can make it impossible for it to circulate sufficient air to prevent the system from freezing up. The same issue can also occur if the blower is malfunctioning or starting to wear out. In this situation, a technician will always fully clean the blower and then test it to see if it needs to be repaired or possibly replaced.

Low Refrigerant Charge

Your AC system needs to have the correct refrigerant charge or level to work properly. When the refrigerant charge is low, it leads to the pressure in the system decreasing. As the pressure decreases, the temperature of the refrigerant also decreases. If the charge is too low and the pressure is below a certain point, the refrigerant can get so cold that the evaporator coil constantly freezes up.

The refrigerant in an AC system flows in a closed loop, which means that the charge should always stay the same. If the charge is low, it often indicates that there is a leak somewhere in the system. However, low refrigerant charge can also occur due to improper maintenance or installation.

13 Reasons Why Your Air Conditioner Is Leaking Water

Written by Kevin on February 18, 2024. Posted in HVAC.

AC leaks cause water damage, mold growth, poor indoor air quality, and many other issues. These leaks are very common in Maryland where the notoriously high humidity can worsen AC condensation and exacerbate leaks. To prevent water damage and humidity-related problems, homeowners should fix AC leaks as soon as possible. Since repairing leaks can be tedious and dangerous, it’s best to let a professional handle the problem.

1. Disconnected Drain Line

A disconnected drain line will cause water to seep out of the air conditioner. This happens because the condensation that forms during the cooling process doesn’t empty correctly. To fix this, the technician will check the drain line and then reconnect it, making sure that it has a secure seal. The technician may use special fittings and supports to ensure the drain line stays connected.

2. Frozen Evaporator Coil

When frozen evaporator coils thaw, leaks may occur. This is usually due to low refrigerant levels, limited airflow, or unclean coils. The accumulation of ice puts pressure on the system and can easily overflow the drain pan. Repairmen fix this problem by checking the airflow, cleaning the coils, and refilling the refrigerant among other things. To prevent further leaks and frozen coils, it is essential to perform preventative maintenance such as replacing the air filter.

3. Clogged Drain Line

Water will back up in the system and create leaks if the drain line becomes blocked, which is usually due to debris or algae development. When this happens, technicians will remove the blockage by vacuuming or flushing the line among other options. Additionally, if the drain line twists or bends, it will not allow water to flow freely and may seem obstructed. When this happens, technicians fix it by moving or straightening the pipe. This restores appropriate drainage and stops the leak.

4. Damaged Condensate Pump

If the condensate pump in your air conditioner wears out or becomes damaged, it won’t be able to drain the water condensate as effectively. If not addressed promptly, this can lead to a leaky AC. To fix this, technicians check the pump and either fix it or replace it so that it works properly again. The best way to keep the pump in good working order and free of leaks is to maintain it regularly.

5. Clogged Air Filter

Some of the most common types of air conditioner filters include washable, pleated, fiberglass and HEPA. You should replace a fiberglass filter once a month, a pleated filter every three months, and a washable filter every three to six months. Keeping the filter clean on a regular basis improves airflow, which in turn reduces system strain and the likelihood of leaks. A clean filter also increases the unit’s lifetime and reduces the likelihood of system breakdowns.

6. Refrigerant Issues

Leaks, low levels or incorrect charging are the most common reasons for refrigerant problems in air conditioners. Corrosion or damage to the lines carrying the refrigerant can lead to major water leaks. Repairing leaks, refilling refrigerant, and checking system pressure are all ways that technicians handle these problems.

7. Blocked Vents or Registers

The limited airflow and temperature imbalances caused by clogged air vents and registers in an AC system can result in AC leaks. To prevent his issues, make sure that there are no objects, such as curtains or furniture, blocking the vents and registers. Always keep the vents completely open to allow the most air to circulate, and dust and clean them regularly. Proper ventilation eases the load on the system. This, in turn, reduces the likelihood of leaks and maximizes the effectiveness of your space’s cooling.

8. Improper Installation

A proper air conditioning installation includes many steps. Technicians must measure the area, choose a suitable unit, run ducts, connect refrigerant lines, fasten the unit, and check its efficiency. The wrong refrigerant charge, sloppy connections or poorly sealed ducts are all examples of how a poorly installed air conditioner can spring a leak. To avoid water damage and keep the AC running efficiently for its entire lifetime, it is crucial to have a professional install the unit correctly.

9. Cracked Drain Pan

The AC drain pan might develop cracks that are causecd by physical damage, corrosion, or normal wear and tear, which can cause leaks. To fix this, technicians check the pan, fix minor cracks, or replace the pan if it’s severely damaged. By keeping up with routine maintenance, you can spot drain pan problems before they cause a major disaster.

10. Leaky Ductwork

An air conditioning system’s ductwork is vital to its efficiency. The top causes of duct issues include poor installation, aging, physical damage, or deterioration that are caused by factors like high humidity. All of these issues compromise seals and joints in the duct system.

Leaky ducts can result in ineffective cooling, higher energy usage, and even water leakage. The technicians take care of this by checking for and fixing any leaks they find as well as making sure that there is enough insulation. Repairing ductwork that is leaking allows specialists to increase system efficiency, stop water damage, and keep cooling constant.

11. Dirty or Blocked Coils

The air conditioner’s coils can become dusty and blocked in a variety of ways. Dust and other airborne particles might eventually settle on the coils. Mold and mildew can form on the coils if the environment is too humid. The buildup of pet hair and dander may cause coil blockage in homes with pets. It’s also possible for the coils to clog if don’t keep a clean air filter. Furthermore, a buildup of outside debris, such as pollen or grass, may jam coils. Dirty and clogged coils can lead to a leaky AC. To address this problem, technicians will clean the coils and recommend regular maintenance.

12. Worn Out Insulation

Insulation in air conditioners helps keep the unit cool and efficient, but it can wear out and eventually cause a leak. It may also deteriorate when exposed to excessive humidity regularly. Incorrect installation, chemical exposure, and insect infestations are other possible culprits. Experts fix this problem by checking the insulation and replacing it if it’s deteriorated. If an insect or pest infestation is the cause, the technician may recommend extermination services.

13. Air Handler Issues

Air handlers are responsible for circulating conditioned air and controlling humidity levels. However, many things can go wrong with an air handler. Some of the most common issues are electrical problems, motor malfunctions, and clogged filters. All of these problems can cause AC leaks.

Service technicians fix this by checking the air handler for damage, fixing or replacing broken parts, and making sure that the air flows properly. Resolving problems with the air handler keeps the system running smoothly, optimizes the unit, and reduces the likelihood of leaks.

Why Your Thermostat Isn’t Reaching The Set Temperature

Written by Kevin on February 13, 2024. Posted in HVAC.

One of the smartest ways to save money on energy bills is to invest in programmable and smart thermostats. Smart thermostats provide remote control and adaptive learning. Both technologies let you schedule energy-efficient temperature changes. These devices lead to enhanced personalized comfort and significant energy-saving capabilities. Maintaining the thermostats regularly enables precise temperature readings and optimal performance. Battery replacement, cleaning, and calibration are of the utmost importance. If you ignore thermostat maintenance and care, you may end up with a device that can’t reach the set temperature. When this happens, expert help is almost always necessary.

1. Incorrect Thermostat Settings

When it comes to home comfort and efficiency, nothing is more important than having the thermostat set correctly. Homeowners sometimes make the mistake of setting their thermostats too hot in the winter or too low in the summer. This makes it difficult for the system to achieve the proper temperature. For example, leaving the fan on the “On” setting is an example of an incorrect setting that might make it difficult to reach the set temperature.

2. Dead Batteries

The average life span of a thermostat battery is six to 12 months; however, this might vary with use. The thermostat’s inability to maintain the desired temperature due to dead or low batteries will cause problems with the HVAC system like ineffective heating and cooling. In order to keep the thermostat running smoothly, it is important to check and replace the batteries on a regular basis.

3. Dirty or Malfunctioning Sensors

The system will not be able to attain the set temperature if the thermostat’s sensors are dirty or not working properly. Erroneous readings caused by dust, dirt or malfunctioning sensors might result in improper heating or cooling cycles. For accurate temperature regulation and peak efficiency from your HVAC system, have a professional clean and maintain the sensors regularly.

4. Poor Thermostat Placement

Misplaced thermostats make it difficult to get reliable temperature readings. As a result, this makes it impossible for the system to attain the set temperature. Do not put thermostats in drafty places or close to heat sources. Placement on inside walls, away from light, windows, and appliances, is ideal.

5. Malfunctioning Heat Anticipator

A premature system shutdown may occur if the thermostat’s heat anticipator isn’t working properly, which throws off the timing of the heating cycle. This can cause the thermostat to fall short of its target temperature, leading to insufficient heating. If you want your thermostat to reliably predict when to turn off the heat for maximum comfort, an expert needs to check and modify the heat anticipator regularly. This mainly applies to older thermostats. Digital thermostats don’t have heat anticipators.

6. Software Glitches

Smart and programmable thermostats rely on complex software for tasks like learning, scheduling, and remote control. These operations are susceptible to disruption by software bugs, which may lead to faulty temperature settings or system failures. To avoid software-related problems, it is vital to update firmware regularly and troubleshoot as needed.

7. Power Supply Problems

If the power goes out or there are variations in the electrical current, the thermostat won’t be able to achieve the temperature you’ve programmed it to. This can lead to false temperature measurements and even a full system shutdown. For the thermostat to consistently work and keep the temperature under control, it is essential to have a steady power supply and to use surge protection. A whole-house surge protector is the best option for protecting your HVAC system against power surges. These devices protect thermostats and other HVAC appliances against sudden spikes in electricity. To further fortify your home’s HVAC system, you can install surge-protected power strips and point-of-use surge protectors for certain equipment.

8. Loose or Damaged Wires

Thermostats malfunction and provide erroneous temperature readings if their wires break or become loose. Experts will double-check the electrical connections during regular HVAC maintenance. The transmission of signals between the HVAC system and the thermostat relies on the correct wiring. It’s very important that you don’t attempt to perform any electrical work yourself. Trained and licensed HVAC workers have the expertise and skill that it takes to perform electrical work safely.

9. Faulty Relay Switches

Thermostats and HVAC systems lose connection if the thermostat’s relay switches are faulty. This can cause the system to malfunction, fail to attain the desired temperature and provide erroneous temperature control. To make sure the relays work properly, have a professional check them often, test them, and replace broken ones.

10. Dirty Air Filter

A dirty air filter limits airflow in an HVAC system. This makes it impossible for the thermostat to achieve the desired temperature. Plus, the system has to work harder due to the reduced airflow, which might cause overheating or overcooling. The easiest way to avoid this problem is by changing the air filter every one to three months, or any time that it is dirty.

11. Corroded Contacts

Thermostats have contact sensors that regulate the temperature, turn the fan on or off and perform other functions. When contacts get corroded, they interfere with these operations and make it harder for the thermostat to attain the set temperature. Humidity, condensation, and contamination are common reasons for corrosion. To keep the contacts from corroding, homeowners should keep the thermostat dry and schedule timely repairs whenever they notice rust.

12. Sensor Calibration Errors

Thermostats use a variety of other sensors. Some sensors gauge the ambient temperature. Humidity sensors measure moisture levels. Occupancy and proximity sensors detect resident activity and user interactions. Flaws in the calibration of these sensors can give rise to inaccurate temperature readings. Because of this, the thermostat may fail to heat or cool the home according to the desired setting because it misreads the ambient temperature. The best way to avoid this issue is by having a professional calibrate the thermostat sensors during every HVAC maintenance visit.

13. HVAC Compatibility Issues

Problems with HVAC compatibility can make it difficult for a thermostat to regulate the temperature. Problems like these occur when the thermostat isn’t designed to work with the specific wiring or technology of the HVAC system. Because of this, homeowners should check to see whether a thermostat is compatible with their HVAC system before buying it. It also helps to talk to experts in the field or read the manufacturer’s compatibility specifications.

14. Display Problems

Electrical problems, broken parts and software errors can all cause thermostat displays to fail, leading to flickering or blank screens. This can make it impossible to know what the set temperature is. Experts take precautions during installation, tie wires securely, and update the thermostat’s software to prevent these issues. To avoid display problems in the future, it’s important to protect the device from power surges and to schedule expert checkups.

A Homeowner’s Guide to HVAC Ductwork

Written by Kevin on February 12, 2024. Posted in HVAC.

The ductwork in your Hanover home is a vital part of the HVAC system. All homeowners should know about the common issues, the various components that make up their system, and the maintenance needs of ductwork. This will all help you to quickly recognize problems and keep your home’s ductwork in the best condition possible.

Ductwork Components

Several parts make up your home’s ductwork system. The supply ducts are usually on ceilings, walls, or floors. They are responsible for transporting the air to the rooms in your home from the HVAC system. You will find the return ducts in a central location, such as ceiling cavities or hallways. These will take air from your rooms and return it to your HVAC unit.

The grilles and air registers function as intake points for return air. They also control the level of airflow in rooms. There are plenums at the ductwork and HVAC unit junction that connect your duct system to your HVAC unit.

HVAC Ductwork Types

You can choose from different types of HVAC ductwork. Flexible ducts have a metal inner cord or flexible plastic, an outer layer, and insulation. This type is versatile, easy to install, and ideal for areas that have limited access. Sheet metal ducts are usually galvanized steel. They are long-lasting, durable, and less vulnerable to damage.

Fiberglass duct board has an outer coating over fiberglass insulation. It is resistant to moisture, lightweight, and good for thermal insulation. There are also rigid fiberglass ducts made from rigid fiberglass boards that are particularly durable with strong insulative properties.

Installing Ductwork

It is imperative to have a professional install your ductwork. With proper installation, you will have reduced energy waste, efficient airflow, and enhanced system performance. A professional will come and inspect your home to ensure that the ductwork is the right size and matches the capacity of your HVAC system.

Professionals will properly seal all of the connections and joints to minimize the leakage of air. They do this via the use of metal or mastic tape. In unconditioned spaces, they will insulate the ducts to prevent heat gain or loss. They will also ensure the proper location of your ductwork so that it works as efficiently as possible.

Ductwork Maintenance and Cleaning

The general recommendation is to have ductwork cleaning and maintenance every three to five years. They will start by doing a visual inspection to look for loose connections, damage, or disconnected sections. This part of the process also includes looking for possible obstructions and ensuring that airflow is consistent.

You should have a professional thoroughly clean your ducts on a regular schedule. This will remove dirt, debris, and other impurities. Without proper cleaning, these impurities get pushed out through the vents and can harm your home’s indoor air quality.

They will check the insulation and sealing of your ductwork. To prevent air leaks, they will reseal any joints or connections that need it. A professional will replace any sections of insulation that have damage. They will pay particular attention to unconditioned areas of your home, such as crawl spaces or your attic. These may require additional insulation to reduce the risk of the air passing through the ducts to experience temperature changes.

Talk to a professional about changing your HVAC filters if you don’t already know how to change them on your own. You should use the manufacturer’s guidelines and the professional’s advice to ensure that you change them regularly to help ensure efficient and clean airflow.

Optimizing Ductwork Efficiency

Regular cleaning and maintenance are vital for optimal ductwork efficiency, but there are some other things you can do too. Throughout your home, you can balance the airflow. A professional can help you to properly adjust your ductwork dampers for this purpose.

Use a high-efficiency air filter for your HVAC system. This helps reduce debris and dust to keep your ductwork cleaner for longer. A professional can help you to choose the best and most efficient filter for your HVAC system.

Consider installing air dampers in your ducts. These allow you to adjust and control the flow of air to different spaces in your home. You can determine the individual needs of the different rooms in your home and optimize the airflow for each one.

Common Ductwork Problems

Homeowners should be aware of the most common ductwork problems. Recognizing these issues and understanding why they occur can help you to know when to call in a professional.

Leaky ductwork can cause conditioned air to leak out, wasting energy. This could also cause uneven cooling or heating throughout your home. If you notice that your home’s airflow is uneven or certain rooms feel drafty, your ductwork may be poorly balanced. A professional can come in and adjust your dampers. With properly balanced airflow, every room in your home will receive sufficient and even airflow and maintain a steadier temperature.

In some cases, something could be restricting the airflow. Check the air vents and make sure that there are no obvious obstructions, such as boxes, debris, or furniture. If this does not solve the issue, you should call a professional to come in and inspect your ductwork. Your ducts may have too many turns, bends, or sharp angles, which could reduce efficiency and make it harder for air to flow smoothly through your duct system.

Over time, aging or poor insulation could lead to disconnected ducts. Air will escape before it can reach your vents and throughout your home. You might notice that the temperature in your home does not match the thermostat. Age-related damage in your ducts, such as tears or punctures, could be to blame. A professional can assess the damage and determine if they can fix it or if they need to replace the damaged ductwork.

Inadequate return air is a relatively common issue. If this occurs, it could result in reduced system efficiency and pressure imbalances. Make sure that there are no obstructions by your return air vents. A professional can also look at them to ensure that they are the right size since improper sizing could also cause this problem.

Ducts in cool spaces without insulation could be susceptible to condensation if there is excessive humidity. This is a potential issue for ductwork in crawl spaces or basements. Over time, this moisture could cause duct material deterioration, mold growth, and reduced efficiency. A professional will come out and inspect all of your ductwork to see if they can make improvements to the insulation to prevent condensation problems.

What is Auxiliary Heat?

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

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

Is Auxiliary Heat The Same as Emergency Heat?

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

Factors that Cause Auxiliary Heat to Come on

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

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

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

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

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

Signs That Your Auxiliary Heat is Always On

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

A Sudden Spike in Your Energy Bill

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

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

No Response to Thermostat Changes

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

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

Defrosting in the Heat Pump

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

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

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

If Your Emergency Heat Setting is On

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

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

Preventive Measures

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

Call the Pros

If something goes wrong with your heat pump, call a professional immediately. It could be bad wiring or poor installation. If your pump is old or worn, you may need a new one. At Beltway Air Conditioning and Heating, we’ll install a new heat pump for your MD home. We serve Colombia, Hanover, and other surrounding areas. Visit our website to learn more.

7 Common Problems That Cause Musty ACs

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

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

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

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

1. Dirty Evaporator Coils

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

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

2. Dirty or Leaky Air Ducts

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

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

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

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

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

3. Excess Moisture in Vents or Ducts

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

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

4. Clogged Drain Pipe

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

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

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

5. Leaky Condensate Pan

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

6. Overfull Drip Pan

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

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

7. Oversized AC

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

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

How to Measure Your Home’s Indoor Air Pollution

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

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

Benefits of Good Indoor Air Quality

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

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

Common Indoor Air Pollutants

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

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

Signs of Poor Indoor Air Quality

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

Unpleasant Odors

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

Respiratory Issues

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

Visible Mold or Mildew

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

Excessive Dust Accumulation

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

Feeling Fatigued or Unwell

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

What Happens During Indoor Air Quality Testing?

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

Types of Air Quality Monitors

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

Benefits of Whole-Home Humidifiers and Dehumidifiers

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

Are you ready to make your home a healthier place to live? If so, Beltway Air Conditioning and Heating is here to help with our wide variety of indoor air quality services. We can also make your home more comfortable thanks to our heating and cooling services, including duct cleaning.

How to Prevent Your Heat Pump From Freezing in Winter

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

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

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

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

What Is a Heat Pump?

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

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

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

What Are the Main Types of Heat Pumps?

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

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

What Causes Ice Buildup in a Heat Pump?

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

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

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

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

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

Ways to Prevent Ice Buildup

Have Your Heat Pump Installed by a Professional

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

Schedule Regular Maintenance

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

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

Use the Defrost Cycle

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

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

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

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

Use a Garden Hose

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

7 Helpful Furnace Troubleshooting Tips

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

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

1. Check Your Furnace Filter

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

2. Check Electrical Panel

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

3. Check The Igniter

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

4. Set Thermostat Correctly

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

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

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

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

5. Clean Out Your Condensate Drain

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

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

6. Check Your Vents

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

7. Remove Clutter From Around Your Furnace

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

Leave All Major Issues Up to the Professionals

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

6 Common Thermostat Issues and How To Solve Them

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

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

1. Your Home Never Reaches Your Desired Temperature

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

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

2. Your Thermostat’s Temperature Reading Is Wrong

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

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

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

3. Temperature Readings Fluctuate

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

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

4. Thermostat Display Not Working

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

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

5. Your Thermostat Lacks Modern Features

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

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

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

6. Your HVAC Keeps Running

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

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