Why Humidity Matters in HVAC?

When discussing the intricacies of HVAC systems, it’s imperative to stress the importance of maintaining the right humidity levels. Proper humidity balance is not just a matter of comfort, but also one of health and efficiency in both residential and commercial spaces.

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.

A view inside HVAC compressor showing components

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.

Is the thought of having to replace an HVAC system sending shivers down your spine—or worse, leaving you in a cold sweat? Fear not, for taking the leap into updating your heating, ventilation, and air conditioning system doesn’t have to be a daunting endeavor. In fact, with the right guidance, it can be a smooth transition that leaves you with a breath of fresh air, quite literally. Today’s blog post is your golden ticket to understanding when, why, and how to efficiently replace your HVAC system, ensuring your home is the epitome of comfort year-round. So sit back, relax, and let’s dive into the world of HVAC upgrades that will transform the way you live.

How Often Should an HVAC System Be Replaced?

Even the best systems have a finite lifespan. Knowing when it’s time to replace your HVAC is essential to avoid the inconvenience of breakdowns and the costs associated with less efficient, older units.

Typically, HVAC systems have an average lifespan of around 15-25 years, with furnaces lasting about 15-20 years, air conditioners running for approximately 10-15 years, and heat pumps providing service for about 15 years.

If you are experiencing any of the following issues, it may be a sign that your HVAC system needs to be replaced:

  • Increased Repair Frequency: If your system requires repairs more often, it could be a sign that it’s nearing the end of its useful life.
  • Rising Energy Bills: An increase in your energy costs could be a clue that your HVAC system’s efficiency is declining.
  • Inconsistent Temperatures: If your system struggles to maintain the set temperature, it may be losing its effectiveness.
  • Strange Noises or Smells: Odd sounds or smells coming from your HVAC system should be inspected as they can indicate serious problems.

If you aren’t sure of when to replace your HVAC unit or are looking for AC repair in Richmond, contact Mode today for assistance.

Which Is the Best Time of Year to Replace Your HVAC System?

Timing your HVAC replacement strategically can save you money, ensure better service, and guarantee a stress-free installation. Most homeowners find themselves in need of HVAC services during the peak of summer heat or the chilling depths of winter. It stands to reason that HVAC companies might be less busy during the milder months of spring and fall.

During these off-peak times, you can often secure better deals as there is less demand for system replacement services. With technicians being less booked up, you’ll find it easier to schedule your installation at a time that suits you. This also means you may have the opportunity to have a more thorough consultation with HVAC specialists, ensuring that all your questions are answered and you get the best system for your home’s needs.

By planning your replacement in the spring or fall, you set your home up for optimal performance when you need it most—in the scorching heat of summer or the icy grip of winter. This forward-thinking approach ensures you’re not caught off-guard by a system failure when you most depend on it.

What is Involved in Replacing Old HVAC Systems?

When considering the replacement of an aging HVAC system, homeowners and building managers face a series of steps that ensure the new installation is efficient, cost-effective, and suitable for their specific needs. Upgrading your HVAC equipment is not a simple plug-and-play operation; it’s an intricate process that requires professional assessment and careful planning. Here’s what the process typically involves:

Assessment and Consultation:

Before any new HVAC system is installed, a thorough assessment of the current system’s condition is necessary. An experienced HVAC technician will evaluate the performance of the existing system, inspect the ductwork for leaks or damage, and assess the insulation and ventilation of the building. During this initial consultation, the technician will also discuss the client’s comfort preferences, energy efficiency goals, and budget considerations.

Choosing the Right System:

Selecting the appropriate HVAC system is critical. Factors such as the size of your home or building, the local climate, and the system’s energy efficiency ratings must be taken into account. Inadequate sizing can lead to inefficient operation, higher utility bills, and a shortened lifespan for the unit. 

Removal of the Old System:

Once the new system has been selected, safely removing and disposing of the old HVAC system is the next step. This involves disconnecting and disassembling the outdated equipment, which might contain refrigerants that need to be handled with care due to environmental regulations. Mode recycles all old equipment with a local metal recycler so you can be sure your old equipment is handled in the most environment-friendly method possible.

Installation of the New System:

Installing the new HVAC system is a complex task that should be handled by certified professionals. This includes setting up the new unit, making electrical connections, and ensuring that the ductwork is properly sealed and insulated. It’s also a prime opportunity to make any necessary upgrades to the ductwork and to ensure that the thermostat is compatible with the new system. Mode installs a new WiFi touchscreen thermostat with every new system. This also a good time to install any air cleaning, purification, or treatment accessories. The cost is typically less expensive if done as an add-on to a system installation.

Testing and Fine-Tuning:

After installation, the system must be thoroughly tested to confirm that it’s operating efficiently and safely. This may involve adjusting the refrigerant levels, calibrating the thermostat, and ensuring that air is flowing correctly through the vents. Any issues that arise during testing must be rectified before the installation is considered complete.

Education and Maintenance Plans:

Finally, the HVAC professionals will provide the homeowner or building manager with detailed instructions on how to best use and maintain the new system. Did you know that Mode Comfort offers preventative maintenance through their Fan Club? Find out more!

Are There Ways to Save on a HVAC System Replacement?

Replacing your HVAC system can be a significant investment, but there are numerous ways to mitigate the costs. Whether you’re looking to upgrade for efficiency, reliability, or comfort, you can employ various strategies to save money without sacrificing quality.

  1. Research and Compare: Begin your journey by researching different HVAC brands and models. Comparing the features versus the cost of each system can help you find the best value for your money. Look for units that strike an appropriate balance between initial cost and long-term savings through energy efficiency.
  2. Energy Efficiency Incentives: Many localities and utility companies offer rebates for installing energy-efficient systems. These incentives can significantly reduce the upfront costs. Make sure to check for programs like ENERGY STAR rebates or local incentives that might apply to your new HVAC system. Be sure to talk to your tax advisor or accountant about these incentives. 
  3. Contractor Deals: Sometimes, HVAC contractors have special deals or discounts, especially during off-peak seasons. Hiring a contractor during the fall or spring might lead to lower prices as demand for HVAC installations decreases.
  4. Proper Sizing: Ensuring your new HVAC system is correctly sized for your home can prevent overpaying for a system larger than you need. A system that is too large or too small won’t run efficiently, leading to higher utility bills and potential maintenance issues down the line. A professional HVAC assessment can help determine the correct size for your home.
  5. Maintenance Plans: Once your system is installed, consider a maintenance plan with your contractor. Regular maintenance can prevent costly repairs and extend the life of your system. Some companies offer discounts on services and parts when you have a maintenance agreement.
  6. Tax Credits: Depending on your location, there may be federal or state tax credits available for installing high-efficiency systems. These can provide significant savings when you file your taxes. Again, talk to your tax advisor or accountant about this topic.
  7. Warranties: Lastly, understand the warranties offered with different systems as repairs may be covered in the future with longer warranty offers.

How Long Does It Take to Replace a HVAC System?

When it comes to replacing your home’s heating, ventilation, and air conditioning (HVAC) system, homeowners often wonder about the time commitment required for such a project. The installation time can vary quite a bit depending on several factors. On average, you can expect the replacement process to take anywhere from several hours for a simple system change-out to a week for a full duct system. Factors like the system complexity, ductwork condition, and permits can affect the overall length. Give us a call today to get an estimate on your project!

Why Won’t My Heat Turn On?

There could be several reasons why your heater does not turn on. It’s important to consider simple reasons before calling a professional for help. By knowing common issues, you will be better equipped to handle heater problems in the future.

Reasons for central heat not turning on

One of the possible reasons could be an issue related to power. Your heating system needs an adequate power supply to function properly. If your home’s circuit breaker may have tripped or if there’s a blown fuse, this could be preventing your heating system from turning on. Always remember to check your power supply before delving into other potential issues.

Another common reason you might face difficulties in turning the heating system on could be due to the thermostat settings. Certifying that the thermostat is set to heat mode and adjusting the temperature above the current room temperature can sometimes resolve the issue.

Problems related to the pilot light are also a common reason why heating systems may not switch on. If you are using a gas heating system and it doesn’t work, there could be an issue with the pilot light. In such cases, it could be a potential gas leak and it’s important to get professional assistance.

Then there’s the possibility of a dirty or clogged filter which could hinder the performance of your heating system. If the air filters are not clean, they could block airflow and strain your system. Regular maintenance and replacement of filters can prevent such issues and improve the efficiency of your heating system. Find out more about Mode’s Maintenance Plans with our Fan Club.

Remember, it’s always important to seek professional assistance should you not be able to diagnose or solve the issue yourself. Always prioritize safety with any home heating concerns! This will not only ensure the longevity of your equipment but also potentially save on costly repairs in the future.

What To Do When My Heater Won’t Stay On?

Heating systems are intricate units, and they can sometimes malfunction especially when you least expect it. If you’ve noticed that your heater won’t stay on, it’s an indication that there could be an underlying issue that needs your immediate attention.

If you’ve already checked your thermostat settings and filter, you could have one of the following issues:

  1. A malfunctioning gas valve or ignition control. It often gets faulty with time or due to a dirty flame sensor. Seek the help of a professional technician to diagnose and fix these components.
  2. Ventilation problems. Blocked vents or flues can make your system switch off frequently due to overheating. Regular maintenance can help to identify potential blockages and prevent heater problems.
  3. Age of system. If your heating system is old, it might be experiencing wear and tear, causing it to keep turning off. In such cases, considering a complete system replacement might be the best option. An investment in a new, more efficient model not only provides peace of mind but also saves on energy costs in the long run.

Regular checks by a certified professional can help detect issues early before they escalate, saving you time and money. Mode Comfort and Air Quality, the best HVAC in Richmond, VA, is just a call away!

Types of Home Heating Systems

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.

Guide on When to Upgrade Your HVAC

We all know that our HVAC systems are crucial for maintaining our homes’ comfort levels year-round. But have you ever wondered just how long HVAC systems last? In today’s blog post, we’re diving into this hot topic, demystifying the average life of HVAC systems and giving you all the cool details. Buckle up for an enlightening journey into the world of heating, ventilation, and air conditioning!

How long does an HVAC system last?

The lifespan of an HVAC system can considerably depend on various factors such as the type of system, its quality, usage, maintenance, and the environment in which it operates. It is critical to understand these aspects to estimate the longevity of an HVAC system accurately. Typically, an HVAC system can last anywhere between 15 to 25 years. However, this range is not absolute. Individual components of the system, such as air conditioners, usually last between 10-15 years, while furnaces can last up to 20 years or more. Heat pumps often need replacement every 10–15 years. For components like boilers, the lifespan extends even further, often between 15 to 30 years. There is no one answer to “how often to replace HVAC systems?” due to all of the variables that must be considered.

When should you replace your HVAC system?

Here are 5 common signs that your HVAC system needs to be replaced:

  1. Increasing Energy Bills: If you’ve noticed a significant increase in your energy bills, it may be time to consider replacing your HVAC system. Older units tend to operate less efficiently, requiring more energy to maintain the desired temperature. Investing in a new, energy-efficient model could save you a significant amount on your monthly bills in the long run.
  2. Frequent Repairs: Do you have the HVAC technician on speed dial? This could be a definite sign that your system is nearing its end. Frequent and costly repairs can add up over time and could indicate that the system is no longer able to function properly.
  3. The Age of the System: The average lifespan of an HVAC system is around 15 to 20 years. If your system is over this age and starting to show signs of wear and tear, it might be more economical to replace it with a newer, more efficient model.
  4. Uneven Temperature Distribution: If some rooms in your home are colder or hotter than others, this could be a sign that your HVAC system is not functioning properly. Age, damage, or design flaws in the system may result in uneven temperature distribution.
  5. Excessive Noise: An HVAC system that’s operating correctly should be relatively quiet. If you’re noticing strange noises when the system operates this may be an indication of potential system faults, and it could be time for a replacement.

How long is a typical HVAC warranty?

The length of a standard HVAC warranty can vary depending on the brand, the model, and the type of system you are purchasing. On average, these warranties range from 5 to 10 years. However, some higher-end models may offer extended warranties that last up to 12-15 years. It’s important to check with the manufacturer or your HVAC installer to get accurate information about the warranty you’re offered.

An HVAC warranty usually covers the functioning parts of the system such as the compressor, motors, and coils. It is designed to protect consumers from potential defects in manufacturing and workmanship that may lead to system breakdowns. However, regular wear and tear, improper installation, and lack of maintenance might not be covered under a standard warranty. For such situations, an extended warranty or service contract might be useful. Mode Comfort proudly offers a 2-year labor warranty on all of our installations. We also offer maintenance plans that will ensure that your system is running properly. Find out more!

How long does it take to install an HVAC system?

Installation time of an HVAC system can vary depending on several factors, including the type of HVAC system being installed, the size and complexity of your property, and whether or not existing infrastructure needs to be removed or repaired. In cases where existing infrastructure isn’t adequate or needs repair, the process may be prolonged. For instance, if there’s a need to repair or add new ductwork, the process will typically take longer. Furthermore, unexpected repair or modification needs such as electrical upgrades or removal of old equipment can extend the installation time. If you only need an air conditioner or heat pump replacement, the project may move faster. Mode Comfort has trustworthy HVAC repair near you. Call Mode Comfort today for an estimate!

What is included in an HVAC system replacement?

With the temperature fluctuation in the Richmond area, it may feel like there is never a best time to replace HVAC systems. Mode Comfort is dedicated to making your HVAC replacement as quick and comfortable as possible. In an HVAC system replacement, various components may be included that are crucial for maintaining the efficiency and functionality of the system.Your replacement may include:

  1. Furnace: This is the powerhouse of your HVAC unit, responsible for heating your home by warming up air and distributing it throughout different rooms. In an HVAC system replacement, your old, worn-out furnace may be switched out for a new, energy-efficient model, improving both heating performance and cost efficiency.
  2. Air Conditioning Unit: Replacements include switching out your old air conditioning unit for a new one. This is responsible for cooling your home during hot seasons, providing comfort and balanced air temperatures. Need AC repair, Richmond? Call Mode Comfort today!
  3. Heat Pump: Instead of a furnace and air conditioner, you may have a heat pump, which does both heating and cooling.
  4. Ductwork: Over time, ductwork can get damaged and/or clogged, rendering it less effective. During HVAC system replacement, new ductwork could be installed to ensure efficient airflow and improved air quality.
  5. Thermostat: Your old, manual thermostat could be upgraded to a programmable or smart thermostat. A new thermostat can provide more accurate temperature control and enhance energy efficiency.
  6. Vents and Grilles: These components that help direct airflow might also be part of a comprehensive replacement. If your existing vents and grilles are damaged or improperly sized, they could hinder the efficiency of your HVAC system.
  7. Filters: Regular maintenance should include frequent filter replacements. However, when getting a new HVAC system, new, perhaps higher-quality filters will also be included.
  8. HVAC Controls System: Your new HVAC system will likely come with a new controls system. These controls will allow you to adjust temperature, airflow, and humidity levels for better comfort.

So, when you plan for an HVAC system replacement, not just the core units but all the peripheral components as well are commonly included in the replacement process. These contribute to overall system performance, enhancing your quality of life by ensuring a comfortable, energy-efficient home environment.

Why is my AC blowing hot air in my house?

It is hot out there, and it is getting hotter. Air conditioning used to be a luxury, but it is now essential to our comfort and health, especially in central Virginia. What happens when your air conditioner stops cooling your home and starts blowing hot air instead? Read on to learn more about the causes of your AC blowing warm air, tips to troubleshoot any issues, and ways to maintain your AC for many years of comfortable cooling.

AC Blowing Warm Air

Why is my AC blowing hot air in my house?

 No one wants to get home and open the door to a hot and humid house. You check the thermostat to see if you set it at the right temperature. You put your hand over the vents to see if the air blowing is cool or warm. You conclude that something is definitely wrong, and you wonder why it is happening. You thought the AC unit still had lots of life left in it. Before assuming the worst, let’s look at the specific reasons why your central air is blowing warm air. Your AC unit blowing hot air outside also might be a concern. Your air conditioner components outside and inside must work together to properly keep your home cool.

Is it the unit itself or some other reason my AC is blowing warm air?

 Reasons an AC might blow warm air:

Refrigerant issues. Low refrigerant levels or a refrigerant leak can lead to your AC blowing warm air. If this is the case, Mode Comfort & Air Quality can professionally inspect the system, locate any leaks and repair them when possible, and recharge the refrigerant if needed.

Faulty compressor. The compressor is responsible for circulating refrigerant through the AC system. When your compressor malfunctions or stops working completely, it cannot provide the cool air you need. This is a complex issue that requires professional assistance, so rely on Mode Comfort & Air Quality to diagnose a compressor issue.

Dirty evaporator coils. These coils are located in the indoor air handler unit and play a vital role in the cooling process. This is where hot air is absorbed and cooled through refrigeration. If these coils become clogged or dirty, it restricts their ability to cool air efficiently. Frozen evaporator coils are often the culprit, as well. 

-Dirty or damaged condenser coils. The condenser coils are located in the outdoor unit. These coils enable the system to remove heat from the refrigerant that was absorbed by the evaporator coils. If these coils are dirty, obstructed (such as by a fence around the outdoor unit), or damaged, this can cause major issues. 

 -Capacitor failure. If your capacitor has died, your unit may blow warm air. Luckily, this is an easy fix.

Potential causes of your Air Conditioner blowing warm air other than the unit itself include:

cooling mode

Thermostat settings or malfunctions. It would be great for homeowners if the only reason the AC is blowing hot air is because the thermostat is set to heat instead of cooling mode. It could also be that the temperature itself is set to higher than the outside temperature so that the thermostat won’t turn on your HVAC system. Your thermostat could be broken or simply need batteries if not hard-wired. Your expert technicians at Mode Comfort & Air Quality perform thorough testing and inspection of all components. You won’t be charged for any unnecessary repairs. 

Airflow restrictions. Check if any obstructions are blocking the airflow from the AC vents, such as furniture, curtains, or other objects. Restricted airflow can prevent the cool air from circulating effectively. If your AC is blowing cold air but the house is still hot, even something as simple as opening closed vents can help get your home cool. You also need to make sure the airflow around the outside AC unit is not obstructed. Debris and overgrown landscaping can cause your AC unit to work harder and overheat. Your outside AC unit needs breathing room to operate efficiently.

Duct leaks. If there is a large leak in your home’s ductwork, cool air may not make it out of the vents into your living areas. Ducts within your home are responsible for delivering the cooled air from the HVAC to the rooms of your dwelling. When there is a leak, warm air mixes with the cold and warmer than normal air is what you feel coming from the vents. Leave any ductwork inspection to the professionals at Mode Comfort & Air Quality.

Dirty air filters. Replacing your air filter as recommended should be the first lesson in Homeownership 101. A dirty or clogged air filter can restrict airflow and reduce the cooling capacity of your AC system. Check the air filters and clean or replace them if necessary. Depending on the type of filter you have in your home, clean or replace filters every 3 months unless you have a lot of dust and pet dander, which requires more frequent attention. 

Electrical problems. Electrical issues, such as a tripped circuit breaker or a blown fuse, can disrupt the AC’s cooling process. Check the electrical panel and reset any tripped breakers or replace blown fuses. 

How can I troubleshoot the problem of my AC blowing hot air?

  1. Check the thermostat. It should be in cooling mode with a temperature set lower than the current room temperature. Change the batteries if necessary.
  2. Check the air filter and change or clean if required.
  3. Make sure your air vents and registers are open and unobstructed.
  4. Verify your electrical power to the AC is on and operable. A tripped breaker is an easy fix to an AC that blows hot air.
  5. Clean the outdoor unit. Hose it down after removing any obstructions that can impact the cooling efficiency.
  6. Call the professionals at Mode Comfort & Air Quality. If you’ve performed the basic troubleshooting steps and the AC problem persists, one call to Mode Comfort & Air Quality will give you peace of mind that we have the expertise and tools to diagnose and repair complex AC issues safely. We can also quickly replace your AC if necessary.

What steps can I take to prevent my AC from blowing warm air in the future?

 The simplest and most cost-efficient way to prevent your air conditioner from blowing hot air is preventative maintenance. This goes beyond changing the air filter. Consider professional AC tune-ups from Mode Comfort & Air Quality, especially if your unit is older. Our quality techs inspect your AC system thoroughly, clean the coil to prevent freezing, clean the condensate line, and test coolant pressure and levels. Schedule your AC tune-up in the spring before it needs to work overtime. You don’t want to regret not calling us sooner when you find your air conditioner blowing hot air on a 90-degree day. Consider joining our Fan Club preventative maintenance program for regular check-ups.

Common FAQs for AC Blowing Warm Air

Why is my AC running all the time but not cooling?

You may find that your home is not cooling down, but the AC blowing warm air is not the problem. Start with looking at simple causes. Are your windows open? Close them so hot air cannot get in and cool air cannot escape. Is your oven on? If you’ve been baking all day, the air in your kitchen area will be warmer than normal. Are children running in and out the door all day, perhaps leaving the door open? Do you have construction happening in your home? Other issues can include insufficient insulation. Inadequate insulation in your home can cause cool air to escape and hot air to infiltrate, leading to prolonged AC operation without proper cooling. Insulating your home adequately, especially in attics, walls, and windows, can help improve cooling efficiency.

Consider the size of your current AC unit. If your air conditioner is too large or too small for the space it’s cooling, it can result in inefficient operation. An oversized unit cools the space quickly but may not run long enough to dehumidify, while an undersized unit may struggle to cool the area adequately. Many homeowners don’t consider the size of their AC unit as the reason why their AC is blowing hot air. Mode Comfort & Air Quality will recommend just the right sized unit to operate to peak efficiency in your home.

Can I fix my AC blowing out hot air on my own?

DIY air conditioning repair is not recommended. HVAC is a big investment for homeowners, and the comfort of your family is very important. You can follow the troubleshooting guidelines above if the AC is blowing hot air on cool, but skip the “how to fix AC blowing hot air” videos on YouTube and go straight to the telephone and call Mode Comfort & Air Quality when you want to answer the question of why is my AC blowing warm air.

When my AC is blowing hot air, who can I call to fix it right the first time?

 You must hire the right contractor to repair your AC unit blowing warm air or replace it when your AC unit is blowing hot air. In Virginia, Mode Comfort & Air Quality is the right choice.

FIXED !BEST TEMPERATURE FOR HEATER IN WINTER AT NIGHT

Winter is a season you either love or hate. Whether you smile or roll your eyes when the forecast includes snow, we all appreciate opening the door to our warm and cozy homes. What temperature on your thermostat is warm and cozy? That answer is influenced by several elements. Outside temperature, inside humidity, your comfort level, and your desire to save money all factor into the best temperature for your heater in winter. The experts at Mode Comfort & Air Quality offers great advice to determine your ideal home temperature in winter.

Energy Star, a program sponsored by the U.S. Department of Energy to promote energy efficiency, recommends a setting of 68 degrees Fahrenheit as the best temperature to set your heater in winter. That may sound a bit chilly to some, but there is reasoning behind the number. Forcing your furnace to keep a high interior temperature with freezing temperatures outside makes your furnace work overtime. A furnace that keeps running means your bills keep going up, too. A more modest temperature of 68 degrees provides just thefh right combination of warmth and savings while increasing the life of your HVAC system. If money savings is a big priority, consider layering your clothing while leaving your thermostat on 68. If you prefer your surroundings a bit toastier, consider a setting of 72 degrees while you are awake and active at home. It will result in a slightly higher energy bill, but it will keep you comfortable when you forgo the hoodie inside

When it comes to the best temperature for your furnace in the winter at night, it is time to turn that thermostat down. As a general rule, the recommended heater temperature at night is between 60 and 67 degrees Fahrenheit. A thermostat setting of around 65 degrees is actually better for your health. When you sleep, your body’s temperature setpoint is lowered, and that makes it easier to adjust to a lower temperature setting on your thermostat. If it is too hot or too cold at night, it can throw off your internal temperature and result in poor sleep quality. Everyone has a different body temperature, so you may have to experiment with your nighttime thermostat temperature to find the right balance.

If you vacation during the winter months, you will also want to lower the temperature on your thermostat. While you are away, the best setting for a furnace in winter is around 60 degrees. You may think that turning off your HVAC system entirely will save money, but it will cost more to get your house back up to the right temperature when you return. You will also increase the chance of freezing pipes if you shut down your furnace or heat pump. If you will be leaving plants and/or pets at home, keep your furnace thermostat set to a minimum of 64 to keep your green leaves and furry friends comfortable and safe.

Even if you are staying put for the winter and can’t wait for the first freeze, the lowest temperature you should set your furnace at is 50 to 55 degrees. This minimum temperature will keep your appliances and pipes in operable condition. Consider this for any vacation properties or unoccupied structures you own. Keep the heat flowing through the house to protect it from potential property damage.

You might have a heat pump instead of a traditional furnace. There are other items to consider when determining the best temperature for a heat pump in winter. Traditional natural gas-powered furnaces generate heat and push it through the ducts of your home via the blower. A heat pump uses ducts, also, but constantly moves air rather than periodically blasting air. Heat pumps take heat from the outside and direct it to your home. When outdoor temperatures fall below freezing, the heat pump utilizes its backup element. Therefore, the best temperature for heat pumps in winter is 68 degrees Fahrenheit. Your heat pump will run efficiently when your home is occupied, and you will be comfortable.

If you have a furnace humidifier, it should be adjusted according to outside temperatures. When temperatures fall between 20 and 40 degrees Fahrenheit, keep the humidity level at 40 percent or below. If temperatures drop below 20 degrees, indoor humidity can be lowered to 25 to 30 percent. Just remember this rule of thumb- the lower the outside temperature, the lower the humidity level inside should be.

Where you place the thermostat in your home is a critical element in energy efficiency. The ideal thermostat placement is on an interior wall in the center of your home. Avoid locating your thermostat in direct sunlight, above air vents, next to a heating source such as your oven or fireplace, or by doors or windows. Consider placing your thermostat in a room you use frequently. Free flow of air around the sensors of your thermostat means it can read temperatures accurately and engage your heating or cooling system as necessary.
