In 2020, the American Innovation and Manufacturing (AIM) Act was enacted into law, which authorizes a 15-year phasedown of hydrofluorocarbons (HFCs) across of a variety of applications. This will have a massive impact on the HVACR industry, notably because R410a, (the prominent refrigerant of today) is an HCFC or a hydrochlorofluorocarbon.

There will be two refrigerants that will be available for all new HVAC equipment starting in 2025 for residential and light commercial use: R454B and R32. These refrigerants are being mandated because they have a much lower GWP or “Global Warming Potential”. The old favorite, R22, which was phased out in 2020 has a GWP of 1810. R410 which has been prominent for the past 20 years and was used to phase out R22 has a GWP of 2088. The allowable limit of GWP will be 700 by 2025. The new refrigerants are referred to as A2L (non-toxic, flammable, and low burning velocity).

Navigating these quicky approaching changes will be difficult for anyone thinking of replacing their systems in 2025 or after. It will be especially difficult for HVAC contractors since the industry has failed dramatically in informing and educating the contractors about these changes. We (HVAC contractors) have been begging for information since we were made aware of this change in late 2022 but our requests have fallen on deaf ears so far.

Here is what we DO know from gathering information from various manufacturer and government websites:

  • We will be allowed to sell and install all R410a equipment that is manufactured in 2024. That stock should be available until mid-2025 while supplies last.
  • The new refrigerants are mildly flammable. Despite their mildly flammable classification, A2L refrigerants are extremely hard to ignite. Extensive testing with A2Ls and numerous heat sources including cigarettes, lighters, power drills, and various household appliances has been done, and no heat source produced ignition.
  • There will be two distinct variations of the AL2 refrigerants available for residential HVAC use: R32 and R454b. Daikin and all of its subsidiaries including Amana and Goodman have committed to using R32. Also, many dehumidifier brands have committed to R32 such as Honeywell, AprilAire, Dri-Eaz and Quest. Most of the other brands have committed to using R454b such as Carrier, Bryant, Trane, American Standard, Lennox, Ruud, Rheem, Nortek, York and all of the sub-brands of these manufacturers. These two refrigerants are not interchangeable and will add an extra layer of confusion for the homeowner. We do not yet know what damage (if any) will occur if they are cross contaminated.
  • There will be cost increases but we do not know how much as of yet. There have been rumors it could be as much as 40%; we are expecting between 10% and 30%. Fortunately for us, we are a Ruud dealer. Ruud redesigned their equipment in 2023 as a result of the DOE regulations that were put into effect that required a minimum efficiency increase of 8-10%. During this redesign they anticipated the AL2 changes and altered the equipment, with a few minor changes during manufacturing they will easily accommodate R454b refrigerants without a complete redesign.  Many of the other manufacturers did not have this foresight and it may result in some shortages come the second quarter of 2025.

As with all big changes, there will be some glitches and bugs that have to be worked out. We saw this in the late 90s when R410a was introduced into the market. My advice to anyone looking to replace your HVAC equipment anytime soon is to do it now before the new equipment and price increases hit.

Assortment of generic electronic capacitors

Many of our service calls are very simple: a blown capacitor. This is good for our customers because capacitors are comparatively inexpensive and quick to replace. Unfortunately, capacitors are a little bit like light bulbs. It might last 3 days. It might last 3 months. It might last 3 years, but it is very hard to tell how long they will last. Thankfully, our expert technicians at Mode Comfort can assist you with any AC issues. 

What Does a Capacitor Do?

The capacitor is the part of a unit that stores and dispenses electrical energy to make the AC or heat pump run. The electricity from the capacitor runs the motors, such as the compressor, the fan motor, and the blower. The main job of a capacitor is to jump start the AC unit or heat pump. Without the capacitor, your unit will not start consistently or run to its top capacity, leading to less quality AC. 

What is the Difference Between a Start Capacitor and a Run Capacitor?

Start capacitors give a jolt to the system to get the compressor and fan motor going. Run capacitors provide the oomph to keep the system running. They might be little, but without them, your unit is essentially dead.

How long do capacitors last for?

Capacitor lifespans can really vary based on the type of product and the conditions with which the AC or heat pump runs. The common HVAC capacitors that you see in many homes can last between 5 and 20 years. The capacitors that are used in industry-sized units can last for much longer. Thankfully, though, doing upkeep on your AC unit or heat pump can result in not needing replacement for 15 to 20 years. At Mode Comfort, we offer HVAC Inspection programs where our technicians maintain the upkeep of your unit so that your capacitor lasts as long as it can.

Why Do So Many Capacitors Fail?

1. Overheating

Capacitors fail if they are in direct sun for too long or if they run for too long, contributing to failure in the air conditioner fan capacitor. 

2. Open capacitors

Sometimes there can be breaks in the circuit of the capacitor, which stops the flow and renders the machine inoperable. 

3. Dielectric Breakdown

Sometimes AC units require high voltage capacitors, which can cause the dielectric materials within the capacitor to break down and fail.  

4. Environmental Factors

Areas that experience intense humidity or extreme weather environments may have earlier AC capacitor failure. Hermetically sealed capacitors are recommended if you live in these conditions. If your AC unit is near any sort of corrosive chemicals, this could damage your unit as well.

5. Service life

As with any appliance, AC units and heat pumps have prospective lifespans. If an AC unit or heat pump is nearing the end of its lifespan, the capacitor may begin to fail. 

6. Insulation resistance

The insulation in the machine is what keeps it from having any sort of electric shock. If the insulation begins to decrease, there can be more frequent short circuits that cause the capacitor to fail. 

7. Capacitance

The capacitance of a device describes its ability to store electric charges. Unfortunately, sometimes the capacitance can exceed the limit for a device, causing it to burn out. 

8. Vibration, acceleration & shock

Any sort of mechanical movement that is not routine for a device can disrupt the function of the mechanisms inside and cause issues with the circuit’s function. 

9. Dissipation factor

The dissipation factor (DF) for a capacitor is the measure of how much energy is lost and dispelled as heat when the AC functions. A low DF is preferred for efficient usage, but a high DF can burn a machine out quickly. 

10. Barometric pressure

Large changes in air pressure can put a lot of strain on an AC or heat pump, and can result in a faulty capacitor. 

11. Radiation

Radiation can be one of the most harmful things to impact a capacitor. If a unit is exposed to radiation, it can degrade the materials and lead to complete breakdown of the unit permanently. 

If you think your capacitor may be failing, it is imperative it is caught and replaced early. Running your unit with a failing capacitor can cause major (and expensive) damage. A dead capacitor can take out a motor or compressor with it, and possibly even cause the unit to fail entirely.

But How Do I Know If My Capacitor is Failing?

You probably won’t know the common air conditioner capacitor failure symptoms, but we will! Preventative maintenance is the key to getting ahead of potential issues. Mode’s Fan Club is only $19.95 per month (for one unit) and that includes two preventative maintenance visits per year. One inspection can cost $150-$200…you can do the math. During these check-ups, we will inspect all aspects of your comfort system, including your capacitors.

There are a few signs of possible capacitor failure modes that homeowners can look for in between check-ups to (although there can certainly be other causes to the below):

  • The compressor struggles to start and then shuts off quickly
  • The unit starts and stops over and over
  • The AC or heat pump is not blowing cold air
  • A humming noise
  • A clicking noise
  • Your system is performing differently than it previously had been

Has your AC or heat pump ever mysteriously stopped working over the summer? Believe it or not, a cause of the slow trickle of cold air could be that your unit has frozen. As the sweltering heat outside battles the bracing cold within your home’s walls, the clash often leads to an icy buildup in your air conditioning unit. In this blog, we’ll defrost the secrets behind this dilemma and arm you with the knowledge to keep your cool all summer long. Need help with your cooling this summer? Call Mode Comfort to make an appointment!

What happens when your AC freezes up?

When your AC system freezes up, it’s crucial to understand the potential reasons behind this common problem. Typically, a frozen air conditioner or heat pump can indicate an airflow issue, such as dirty air filters or blocked vents, which prevent your system from functioning efficiently. Another possible cause is low refrigerant levels, which can occur due to leaks or insufficient charge, causing the evaporator coils to get too cold and ice over. A frozen AC not only reduces cooling performance but can also lead to more severe damage if not addressed promptly. By taking quick action and performing routine maintenance, you can extend the life of your air conditioning unit or heat pump and ensure it operates at peak efficiency during those sweltering summer months. Find out about our HVAC repair services!

Signs of AC Freeze Up

  • Ice on the evaporator coils: When your air conditioner or heat pump begins to freeze up, you might notice a buildup of frost or ice on the evaporator coils, which are located inside the air handler.
  • Visible frost on the refrigerant lines: The lines that carry refrigerant may also show signs of frost or ice, indicating that the AC unit is operating below its normal temperature range. This could be a sign of the AC lines freezing.
  • Reduced airflow from vents: If there’s a blockage caused by ice, you may experience a significant decrease in air flowing out of your home’s vents, making the AC less effective at cooling your space.
  • Water leaks around the AC unit: Melting ice can lead to water pooling around the air conditioner or heat pump, which is not only a sign of a freeze-up but can also cause water damage to your home. Please note that high humidity may also cause your unit to sweat.
  • Unusually high utility bills: A frozen AC unit has to work harder to cool your home, which can lead to an unexpected increase in your energy costs.
  • Blower fan running continuously: The blower fan might continue to run as it tries to push air through the blocked system, and this constant operation can be a sign that the system is frozen.
  • System cycling on and off frequently: Short cycling, or the system turning on and off repeatedly over a short period, can indicate that the AC or heat pump is having trouble maintaining the desired temperature due to a freeze-up.

Common Causes of an AC Freeze Up

Close-up of HVAC internal wiring

  • Low refrigerant levels: When the refrigerant in your AC unit is low, it can cause the pressure in the system to drop, leading to the evaporator coil freezing over.
  • Insufficient air flow: If the air flow across the evaporator coil is restricted due to a dirty air filter or blocked air ducts, the coil may not be able to transfer heat effectively, causing it to freeze.
  • Dirty evaporator coils: Over time, coils can become coated with dust and debris, insulating the coil and preventing it from absorbing heat from the air, leading to a freeze-up.
  • Faulty blower fan: The blower fan helps circulate air over the evaporator coil. If it is malfunctioning, air won’t move as it should, potentially causing the coil to freeze.
  • Collapsed ductwork: Crushed or collapsed air ducts can significantly restrict airflow, increasing the likelihood of the evaporator coil freezing.
  • Closed supply registers: If too many supply registers are closed, it can reduce the airflow to the evaporator coil, contributing to the freezing problem.
  • Running AC when it’s too cold outside: Using the AC when outdoor temperatures are too low can cause the refrigerant to run cooler than designed, potentially leading to frozen coils.
  • Thermostat issues: If the thermostat is malfunctioning, it might cause the AC unit to run longer than necessary and cool to the point where the coils freeze.
  • Drainage problems: If the drain pan or drain line is blocked, water can back up and freeze on the coil, especially when it’s combined with other factors like low airflow or dirty coils.

How to Fix a Frozen Unit

  1. Turn Off Your HVAC System: This may seem obvious, but it’s a vital first step. Continuing to run a frozen system can cause more harm. Switch the unit off at the thermostat and at the breaker if necessary.
  2. Allow the Unit to Thaw: Depending on the extent of the AC freeze up, this might take a few hours or even a full day. Place towels around the unit to absorb any meltwater. If your unit is indoors, consider using buckets and make sure to monitor the situation to prevent any water damage.
  3. Inspect Air Filters: While you wait for the unit to thaw, check your air filters. Dirty filters restrict airflow and can cause the system to freeze. If they’re dirty, replace them.

Further Diagnostic and Fixes

  1. Check Vents: Ensure all supply and return vents are open and free of obstructions. Blocked vents can lead to a buildup of cold air and moisture in the system. 
  2. Inspect the Blower Fan: After thawing, but before turning the unit back on, check if the blower fan is working correctly. A broken or malfunctioning fan can’t circulate air, leading to freezing.
  3. Look at the Evaporator Coils: If your filters are clean and vents unblocked, the problem might lie with the coils. If there’s dirt on these coils, clean them carefully. Be gentle to avoid damaging the fins.
  4. Examine the Refrigerant Levels: Low refrigerant levels can reduce pressure in the system, leading to an air conditioning unit freezing up. This fix usually requires a certified technician, as it involves handling potentially hazardous materials and checking for leaks.

How Do I Keep My Air Conditioner From Freezing Up?

A family enjoying time together in a living room.

To prevent future freeze-ups, regularly change your air filters, schedule annual maintenance checks with a certified HVAC technician, and ensure proper insulation and sealing of your home to keep the air temperature around the unit as stable as possible. Blocked or restricted airflow can cause the unit to work harder, leading to an overworked system and potential AC freeze up. So, keep your vents open and unobstructed to promote efficient operation. Furthermore, pay attention to the coolant levels—low refrigerant could be a culprit in reducing your AC’s efficiency and causing it to freeze. Also, during hot summer months, avoid setting your thermostat too low, as overcooling can also cause freezing issues. Stick to recommended temperature settings and consider using a programmable thermostat to optimize your home’s cooling schedule. Remember, preventing AC freeze-ups not only extends the life of your unit but also keeps your energy costs in check, making it an eco-friendly and cost-effective practice. Keep these tips in mind, and enjoy a cool, comfortable home without the dreaded freeze-up.

FAQs

How long should I leave my AC off if frozen?

As a general rule of thumb, it is safe to leave your frozen AC unit switched off for at least 24 hours. This time frame should be sufficient for the ice to fully melt in most conditions. Please note that larger units suffering from AC freeze up with a significant amount of ice may require more time, potentially up to 48 hours.

Why is my brand new AC unit freezing up?

One of the most common causes for an AC unit or heat pump to start freezing is insufficient airflow. Your AC unit’s evaporator coils need a steady stream of air to absorb heat effectively. If the airflow is restricted, the temperature of the coils can drop too low, leading to the condensation on them freezing over. If you are having problems with your new AC or heat pump, learn more about Mode’s AC installation and repair services.

When should I call a professional for an AC freeze up?

If you’ve completed these steps and your unit continues to freeze, or you’re not comfortable performing any of these tasks, it’s time to call a professional. Mode Comfort’s technicians have the tools and expertise to diagnose complex issues and perform safe repairs.

The Impact of Home Humidity Levels on Comfort

From a comfort standpoint, the humidity level in the air can play as much of a role as temperature. Air that is too dry can cause irritation to our skin, eyes, and respiratory system. This is particularly noticeable in the colder months when HVAC systems are used to heat indoor spaces, which can reduce indoor humidity. Conversely, air that is too moist can make a space feel stuffy and warmer than it actually is. This often happens in summer months, causing HVAC systems to work harder to maintain a comfortable temperature.

HVAC Efficiency and Humidity

Efficiency is yet another facet of the HVAC system’s functionality that’s affected by humidity. An HVAC system in a highly humid environment will consume more energy because it has to work harder to remove the excess moisture from the air to reach the desired comfort level. Therefore, managing humidity is not just about maintaining a comfortable indoor climate, it’s also about optimizing the efficiency of the HVAC unit, leading to potential energy savings and prolonged system life.

Problems Caused by High Humidity Level  in Home

  • Health Issues: High humidity levels inside your home can be much more than a mere discomfort; they can have significant effects on your health. Breathing in overly moist air could potentially result in respiratory problems due to the growth of mold and mildew, which thrive in damp conditions. Not only do these fungi produce an unpleasant musty odor, but they can also release spores into the air that may cause allergic reactions, asthma attacks, and other respiratory issues, especially in those with weakened immune systems.

  • Structural Damage: The integrity of your home’s structure can also be compromised by high humidity. When the air is laden with moisture, it can find its way into walls and wooden supports, leading to warping, cracking, and the breakdown of structural strength. This weakening may go unnoticed for a long time, quietly progressing until it becomes a serious issue requiring expensive repairs.
  • Pest Infestations: Pests like dust mites, cockroaches, and termites are all attracted to moist environments. These unwanted critters can set up shop in your home if humidity is left unchecked, creating infestations that can damage your property and exacerbate health concerns. Moreover, the presence of these pests can bring about additional costs in pest control and add to the overall unhealthiness of your indoor environment.

Problems Caused by Low Humidity Level in Home

  • Flu and Cold Protection: When the humidity levels in your home drop significantly, it can lead to a host of health-related problems. Low humidity dries out the mucous membranes in your nose and throat, which can diminish your body’s ability to fend off cold and flu viruses. This is why many people find they are more prone to illnesses during the colder months when indoor humidity levels tend to be lower. Moreover, people suffering from asthma may experience more frequent and severe episodes as dry air can irritate the respiratory system.
  • Skin Irritation: The lack of moisture in the air can cause your skin to become dry, flaky, and itchy. In extreme cases, your skin may even crack, which can be painful and opens the door to potential infections. Additionally, those with sensitive skin conditions, such as eczema or psoriasis, may notice a worsening of their symptoms when the indoor air is too dry.
  • Structural Damage to Your Home: Your home can also suffer from low humidity levels. Wood floors, furniture, and musical instruments like pianos are particularly susceptible to damage when the air in your home is too dry. Wood can warp, crack, or split because it contracts when it dries out. This not only affects the appearance and integrity of your expensive household items but can also lead to costly repairs or replacements.
  • Electrical Hazards: Another less obvious problem caused by low humidity is the increase in static electricity. This can be a mere nuisance, giving you small shocks when you touch metal objects, fabric, or even other people. However, it can pose a serious threat to sensitive electronics, possibly damaging them or wiping out important data.

What’s the Best Home Humidity Level?

Most experts agree that the normal humidity level for comfort and for avoiding health issues typically ranges from 30% to 50%. In this range, you strike a balance between eliminating problems that come with air that is too dry or too moist.

Ideal indoor humidity in winter

When the outdoor temperatures drop, the air becomes drier, and heating systems working overtime can strip what little moisture remains, potentially leading to a host of undesirable effects.

To maintain ideal humidity levels of 30-50% in winter, you might need to employ some strategies:

  • Use a Humidifier: A humidifier is an effective way to add moisture back into your home’s air. They come in various sizes, from units suited for a single room to whole-house systems that work with your heating system.
  • Keep an Eye on the Hygrometer: This tool measures the moisture in the air. Some digital thermostats have built-in hygrometers, but you can also buy standalone units.
  • Indoor Plants: Adding houseplants can help to naturally increase the humidity inside your home as they release moisture vapor into the air as part of their natural breathing and transpiration process.
  • Ventilation: Proper ventilation is key to maintaining humidity at healthy levels. For instance, using exhaust fans in the kitchen and bathroom can help remove excess moisture that could contribute to mold growth.
  • Seal Leaks: Make sure that your home is well-sealed to prevent the loss of warm, humidified air and the influx of dry, cold air. This includes sealing gaps around windows, doors, and other potential air leaks.

By managing the proper humidity for your house during winter, you can improve your comfort, protect your health, and extend the life of your home’s interior features. Regularly monitoring and adjusting humidity levels will help you maintain a cozy and healthy living space all winter long. Read more about heater temperatures in winter!

Ideal home humidity in summer

When we talk about the ideal humidity in your house in summer, we consider the same home humidity recommendations as you would in winter. The perfect balance ensures not only our personal comfort but also the well-being of our homes and the longevity of our belongings. Once you’re aware of your home’s humidity levels, there are several methods to control it:

  • Air Conditioning: An AC doesn’t only cool your home but also reduces humidity by pulling moisture from the air.
  • Dehumidifiers: These can be particularly beneficial in high-humidity areas or during exceptionally humid periods.
  • Use Fans: Good air circulation can help keep humidity levels down by drying out damp air.

Have you ever wondered what could bring your air conditioner to a sudden halt in the midst of summer? One likely culprit is a capacitor failure, a common but often overlooked cause of AC and heat pump woes. This seemingly small component really impacts the overall functionality of your cooling system, as it stores the electrical energy that starts your unit’s motors. In this post, we’ll dive into the nitty-gritty of air conditioner and heat pump capacitor failure causes, helping you understand the warning signs and how to prevent this from putting a damper on your comfort.

What Is an AC Capacitor?

An AC capacitor, also known as a run capacitor, is a small but essential component designed to store and release electrical energy in an alternating current (A/C) electrical circuit. It’s often compared to a temporary battery. One of the primary roles of an AC capacitor is to assist in starting up the air conditioner or heat pump’s motors. These motors can be quite large and require a significant amount of energy to overcome initial inertia and begin rotating. The start capacitor releases its stored energy to create a high-torque start-up boost. Normally, this component operates for just a few seconds each time the motor starts.

In addition to helping the motor start, capacitors are crucial for the continuous running of the AC or heat pump unit. They are responsible for maintaining a consistent and steady flow of electricity to the motor, which helps the motor run more efficiently, reduces energy consumption, and can prolong the overall lifespan of the AC or heat pump unit. 

There are some signs of AC capacitor failure to keep an eye out for. If your AC or heat pump unit is not turning on, or taking longer to start, or you hear a humming noise, there could be issues with your system. If you notice the AC or heat pump unit shuts off while it should be running or has trouble maintaining temperature, or your energy bills are higher than usual, the AC Capacitor could be your issue.

Since the AC Capacitor is such an important part of the structure of the unit, it is recommended that you schedule regular maintenance with an HVAC company. Mode Comfort services HVAC needs in the greater Richmond area and can assist with Air Conditioning Installation and Repair . Having our experts check out your system regularly can ensure that you avoid any costly issues associated with a failing capacitor.

What Causes a Bad Capacitor?

You may be asking yourself: Why do AC capacitors fail? It is essential to familiarize yourself with signs of a failing capacitor and take quick action before the issue escalates into a costly repair—or worse, a complete system breakdown where your home AC or heat pump is not working. Remember, preventive measures and early detection can save you time and money in the long run. Let’s look into some of the leading causes of capacitor issues.

1. Overheating

When an air conditioner or heat pump’s capacitor starts to overheat, it can be due to a variety of reasons, including extreme temperature conditions, overuse during hot weather, or lack of proper ventilation around the unit. Proper insulation of the electrical components, including the capacitor, can also avoid overheating. Ensuring your AC or heat pump system is correctly sized for your space can prevent undue strain on the capacitor.

2. Power Surge or Overload

These unexpected spikes in electrical current can cause severe damage on the delicate electronics within your AC or heat pump unit, including the capacitor. Electrical surges might stem from a variety of sources, such as power outages, lightning strikes, or even the irregularities from your power supply company. A capacitor acts as a buffer to protect the motor, but a strong enough surge can overwhelm it, leading to capacitor burnout. To mitigate this risk, it’s recommended you install surge protectors for your HVAC system. These protectors can help shield your air conditioner or heat pump from the brunt of electrical spikes, thereby extending the life of your capacitors and ensuring the continued effectiveness of your cooling system. 

3. Worn Out or Damaged Parts in an AC Capacitor:

There are a few parts to keep an eye on to ensure they are working properly. Make sure the metal terminals of an AC capacitor aren’t rusting due to environmental moisture, leading to poor electrical conductivity and the need for part replacement. Some capacitors are filled with oil, and a leak can signal the breaking down of the capacitor’s seals, resulting in diminished performance or failure. When tested with a multimeter, a capacitor showing a significantly lower capacitance than its rated is likely worn out and needs replacing. A swollen end on a capacitor is a visual cue that internal AC capacitor failure has occurred, typically requiring the part to be changed out. Having regular maintenance scheduled with an HVAC company like Mode Comfort can allow you to avoid any AC or heat pump parts getting to the point of no return.

How Do You Determine Capacitor Failure?

By recognizing the common signs of capacitor issues, such as a humming noise from the AC or heat pump unit, the air conditioner struggling to start, a swollen capacitor case, or a completely non-functional cooling system, you can address potential problems before they lead to more significant damage. Regular maintenance checks that include inspecting for dust and debris, examining the electrical connections, and ensuring the correct voltage is supplied can help mitigate risks. Notably, capacitor failures are often due to overheating, so making sure the condenser coils are clean and the unit is not exposed to overbearing temperatures can make a difference.

If you are having trouble with your heating system, it’s important to know what type of system you have so you can convey this information to your HVAC professional. Most likely, you have one of the following systems.

  1. Furnace Heating Systems: The most popular type of home heating in the USA, furnaces work by blowing heated air via ducts, delivering warm air to different rooms through vents. The heated air comes from burning either oil or gas. If you have a heating system that is located inside your home and is connected to ducts, it most likely is a furnace.
  2. Boiler Heating Systems: Boilers heat water and distribute heat through radiators or pipes. This hot water can also be used in a radiant floor heating system, which is known for providing even heating throughout the residence. If you have radiators or a heating system that is connected to pipes, it is most likely a boiler.
  3. Heat Pump Systems: These systems use electricity to move heat from a cool space into a warm one to keep your home warm in the winter. They can also be reversed to cool a home in the summer. If your system runs on electricity only, it is most likely a heat pump.
  4. Direct Heating Systems: These include gas-fired space heaters, fireplaces and wood-burning and pellet stoves. These systems typically heat only the room in which they’re located. Is your heater not turning on? If you only have direct heating systems in your home, you should consider upgrading to a central air system for maximum comfort in the winter. Heater problems shouldn’t leave you out in the cold.
