There better be a good reason when your AC is blowing hot air in your Northwest Florida home. After all, walking into your home on a hotter day to cool off only to realize that warm air is coming from your vents can be one of the worst feelings. But what causes your cooling system to blow hot air, and what can you do about it?

Please continue reading to unveil the common causes of why your AC is throwing hot air and how to fix this issue.

Reasons Why Your AC is Blowing Hot Air

The following problems can make your cooling blow warm air instead of dispersing the cold air that you’ve been craving:

Clogged Air Filters

Your system’s air filters are responsible for trapping all kinds of particles and pathogens in the air. Though air filters help improve indoor air quality, they can become saturated over time. Dirty and clogged air filters restrict cool air from circulating correctly throughout your home. Also, it can cause your system to overwork, leading to other AC repairs.

In order to keep your system working efficiently, make sure to change your air filters every 30 to 90 days. However, this frequency may vary depending on the following factors:

  • The type of air filters
  • Workload of air conditioner
  • Number of smokers in your home
  • Number of pets
  • Number of allergy sufferers
  • Square footage of your home

Malfunction Compressor or Thermostat

The thermostat and compressor play a significant role in maintaining a comfortable temperature in your space. If any of these components are not adequately maintained, it can cause your air conditioner to blow hot air. Also, you should set your thermostat accurately. If it is set to “Heat,” change that setting to “Cool” if you want your cooling system to blow cool air.

Dirt Evaporator Coils

Evaporator coils play a critical role in determining how your air conditioning system cools the air. Located in the air handler unit, these coils are where the hot air is absorbed and cooled by refrigeration.

If evaporator coils become dusty or clogged, they can restrict your system’s ability to cool air properly. While it is best to let professional HVAC technicians handle this issue, you can clean these coils by yourself by gently wiping the debris with a soft cloth.

Refrigerant Leak

A refrigerant leak can be a significant cause of why your AC is blowing hot air. The low refrigerant levels of your air conditioning system will expand the chemical liquid, allowing it to escape the refrigerant line through a leak. If your AC coils are frozen, the system can’t extract the hot air from your home, sending it back unconditioned.

Setting your thermostat accurately, preventing refrigerant leaks, and cleaning air filters can help you prevent your cooling system from blowing warm air.
