Why Is My AC Blowing Warm Air?

Once the temperatures start to rise, you want to stay cool and refreshed. If your AC system starts blowing out warm air in the middle of a hot day, you’ll instantly be worried and confused. What could be the cause of this malfunction? Here are a few reasons why your AC may start blowing warm air, so you can get an expert technician on the case and fast!

Clogged Air Filters

One of the most common reasons why your AC system may start blowing warm air throughout the house is a clogged air filter. A clogged air filter can interfere with a variety of parts in your air conditioning, even your thermostat! When an air filter is clogged or dirty, this can prevent the passage of cold and warm air, which causes the evaporator coils inside the unit to freeze. When this happens, your AC system starts to blow warm air. Make sure to regularly replace your air filters to prevent an issue like this from happening.

Thermostat Issues

A very simple reason why your AC system may be blowing warm air may just have to do with the thermostat setting. Make sure your thermostat is set to cool, and if not just switch the dial over to the cool setting. If your thermostat needs batteries or the temperature is set too high, this can be another component that causes warm air to be expelled from your AC unit.

Needs Refrigerant

An air conditioning unit that is blowing hot or warm air may also be running low on refrigerant. Refrigerant (also known as coolant) should only be refilled by an experienced technician! Call your trusted HVAC company to have a professional take a look at your air conditioning unit, because there may be a leak that caused the amount of refrigerant in your system to lower.

Unit Needs Replacement

The average lifespan of a regular air conditioning unit can range from 15 to 20 years, depending on further maintenance and repairs as needed. If you find your air conditioning unit is blowing warm air and struggling to cool your home, it may just be time for a replacement of the air conditioning system. Contact a trusted HVAC company to learn more about replacement and get your home prepared for hot temperatures with a brand-new working unit!
