4 Common Reasons Why Your AC Will Blow Hot Air This Summer

Phoenix summers are known for their intensity, with daily temperatures in the triple digits and air conditioning bills skyrocketing. If your A/C is blowing hot air during the summer, then you are already too late. Avoid this issue and have your unit inspected ahead of time. ACE’s expert staff can help you beat the heat!

4 Common Reason Your Unit is Blowing Hot Air

If you air conditioner is blowing hot air, it’s more than likely due to one of these four reasons. If not, be sure to contact your local HVAC company for professional assistance.

ACE Home Services: HVAC Blowing Hot Air Not Cold - Freon

1. Low Refrigerant/Freon Levels

One of the most common reasons your unit isn’t cooling is because it is low on refrigerant, usually Freon. Freon helps cool the air in the unit as it is pushed through vents and circulates in your home. Refrigerant leaks can cause your unit to only blow hot air. You can visibly see if your A/C needs more Freon if ice begins to form on the outside, and inside, of the unit. Call ACE today to have a professional come recharge your unit with Freon.

2. Dirty Coils and Dirty Air Filters

If you haven’t changed your air filter within the last six months, it may be time for a replacement! Over time, air filters can become clogged and soiled with dirt and pollutants. A dirty filter promotes a dirty evaporator coil, which prevents your A/C system from properly cooling. Be sure to change air filters as needed. If your filter has already affected your evaporator coil, there’s no need to worry! Call ACE today and we will send on of our certified technicians to come to your home, clean your coil, and restore your unit’s functionality.

3. Blocked Unit

Debris and dirt can accumulate by your A/C unit outsides. If you walk outside and examine your unit, is there anything blocking it? Make sure that there is proper air flow to the condenser coils and your unit’s ability to cool is not blocked by outside waste. With Phoenix’s random haboobs and dust storms, you may also need to schedule regular cleaning of your condenser coils, removing any unwanted dirt.
