After a long winter, spring is finally here. You may be working in your yard and getting the rest of your Philadelphia home ready for spring. After working hard outside, you want to be able to escape the heat in your nice, air-conditioned home. Unfortunately, if there is an issue with your HVAC system, it may start blowing warm air into your home. This isn’t what you wanted.

There are a variety of reasons why your system may start blowing warm air. Below are just some of the most common. To properly diagnose the problem, however, you should call on a professional HVAC contractor like Modern Air Solutions in Bensalem, Pennsylvania.

Thermostat Issues

If your air conditioner is blowing warm air, the cause can be something as simple as your thermostat. If you have kids, they may have been curious and started pressing random buttons on your thermostat. Someone in your family can also bump the thermostat and accidentally changed the setting.

Make sure your system isn’t set to heat. Then check to see if your thermostat is on “auto” or “on”. When the system is “on”, it will still run the fan even if your outdoor unit isn’t actually cooling the air. In this case, you will likely feel warm air or air that is just not cool blowing out of your air vents.

Compressor or Refrigerant Issues

The compressor (on your outdoor unit) is responsible for circulating the refrigerant (which absorbs heat) through the coils of your indoor and outdoor unit. If the compressor isn’t working, your entire system will fail to operate properly.

There are many reasons why a compressor can fail. Some reasons include dirty coils, contaminants in your system, restricted air flow, refrigerant leaks, and electrical problems. This is why it is important to schedule annual maintenance from professionals like Modern Air Solutions. Annual maintenance allows you to keep your HVAC system running efficiently, helps prevent problems, and allows you to catch small issues before they turn into more expensive repairs.

Airflow Issues

An HVAC system needs to be able to breathe to function properly. If the airflow in your system is restricted, it may not cause warm air to blow, but it can reduce the amount of cool air blowing into your home. This is why it is so important to change your air filter regularly.

Also, if your air ducts are dirty, broken, disconnected or set up poorly, the amount of conditioned air making it into your home is reduced. Then your HVAC system has to work harder to cool your home and your utility bills will rise.

Electrical Issues

There are also a variety of electrical issues that can occur. Your HVAC system has plenty of wiring that can get frayed, cut, chewed, or disconnected. If something like this occurs, your system can stop working properly or all together.

Some other electrical issues include a blown fuse or tripped breaker switch. HVAC systems require a lot of electrical power to start up. If the demand is too high the circuit breaker may shut off to ensure safety. If the breaker was tripped you can switch it back on, but if a fuse has been blown it will need to be replaced. Make sure to always be safe. If you are not absolutely sure you know what you are doing, hire a professional.
