Air conditioning is essential during hot summers, and homes quickly become uncomfortable if there is a problem with the HVAC. There are multiple reasons why your system might be blowing hot air; some you can fix quickly, while others need the skills of an air conditioning contractor. Below are the most common reasons hot air may be coming from your air conditioning. 

Why Does Your Air Conditioner Blow Hot Air?

1. Low Refrigerant 

Not having enough refrigerant in the air conditioning is one of the most common causes of unwanted hot air. Ice forming on indoor and outdoor units is a sign that the refrigerant is low. If you have a refrigerant leak, you should contact an air conditioning contractor to deal with the problem.

2. Problem With Outdoor Unit

The outdoor unit of your air conditioning is just as significant as the indoor unit, and an issue could lead to hot air blowing into your home. One possible issue with the outdoor unit is that debris is blocking the condenser coils, and you will have to clean it to get everything working well again. There could also be an electrical problem, such as a blown fuse or a tripped circuit breaker. 

3. Requires Maintenance

When certain parts of your air conditioner get clogged with dirt, this will stop the system from cooling as efficiently as it should. A dirty air filter will lead to dirty evaporator coils, and you’ll need an air conditioning contractor to clean the coils and get your unit blowing cold air again. The best way to avoid problems is by asking a contractor to perform annual maintenance. 

4. Accidentally Set to Heat

This one sounds obvious, but it’s possible that you pushed the wrong button on your thermostat or remote and the air conditioning is now set to heat. Even if you’re sure you set it to cool, it may be that someone else in your home knocked the button by mistake. Luckily, this is a straightforward problem to fix.

5. Air Duct Issues

Leaking air ducts are a cause of unwanted hot air coming from air conditioning because it can’t efficiently move fresh air around the home. You will have to reseal the ducts to fix this problem. However, the ducts located in the attic, walls, or basement are challenging to access, so leave resealing to the professionals.
