Why Is My AC Blowing Hot Air?

My AC Is Blowing Hot Air
|

There is nothing worse than suffering through the heat when your AC breaks down in the middle of summer. While there are many reasons why your air conditioner might be blowing hot air, below are a few of the main causes.

Your Thermostat Is Set Incorrectly

As silly as this sounds, one of the most common reasons an air conditioner blows hot air is that the thermostat is actually set to the “heat” mode. We are all guilty of making this mistake every once in a while. The good news is, it’s an easy fix! Just switch it back to “cool” and the problem is solved.

Your Air Filter Needs to Be Changed

Your air filter works to remove dust and dirt from the air in your home to keep it clean. Without changing it often enough, it can become severely clogged and full of debris.

Air filters trap:

  • Dust
  • Pollen
  • Dust mites
  • Dirt
  • Pet dander
  • Mold spores

When an air filter is full enough, it can block air from reaching your indoor AC unit, effectively preventing it from cooling your home adequately. You should check on your air filter once a month and change it whenever it is visibly dirty.

Your Outside AC Unit Could Use Some TLC

Your outside AC unit, also known as the condenser unit, needs to be regularly maintained. If there are leaves, dirt, or other materials blocking it, it cannot function properly. In order to prevent the breakdown of your condenser unit, check it regularly and remove any blockages.

Your AC Is Low on Refrigerant

Refrigerant is the liquid that absorbs heat from your air in order to cool it down. When your refrigerant is low, it is not able to effectively remove heat from your air and cool your home. Unfortunately, refrigerant doesn’t get used up, so if it is low, that means you have a leak. If you suspect your refrigerant is low, you need to call in a professional who can locate the leak, repair it, and refill your refrigerant.

Your Breaker Switch Is Blown

When your AC is blowing hot air, it could be due to a trip in the breaker. Your air conditioner has one breaker for the indoor unit and one for the outdoor unit. Sometimes, if the outside unit’s breaker trips, the indoor unit is still able to bring in air, but it cannot be cooled while the outdoor unit is down. This means that your indoor unit might just be circulating warm air from outside into your home. Try flipping the breaker back to the “on” position, and if that doesn’t solve the problem, you will need to call an electrician.
