Why Is My Home Air Conditioner Blowing Hot Air?

Posted on: April 30, 2019

The last thing you want your Florida air conditioner to do is to blow hot or warm air. There’s plenty of that to be had outdoors, and you need your system to be providing cool, crisp air in addition to a measure of dehumidification.

Are you searching for an answer to “why is my AC blowing hot air?” If so, the experts at Iceberg Cooling can help. The following is our brief list of the most common causes, and how to troubleshoot them.

The AC Needs a Filter Change

Leaving the air filter in your HVAC system unchanged for too long can lead to severely restricted air flow. This often leads to the AC shutting off due to overheating, blowing small amounts of dirty air, or blowing hot or warm air.

For the best results we recommend changing your air filter at a minimum of once every two months; once a month may be better during extremely hot weather.

The Thermostat Is Set Incorrectly

The thermostat may still be set to “heat” mode, or maybe someone in your home accidentally (or on purpose) has changed the settings. No matter the cause, be sure to check for the possibility of this being your issue before calling your local HVAC company—it wouldn’t do to have to pay a diagnostics fee for an issue that is so easily overlooked!

Dirty Components

Components like the outdoor-located compressor and condenser, and especially the indoor evaporator coil, need to keep clean to perform their functions properly. Dirty evaporator coils restrict your system’s ability to cool air and remove heat, which often leads to the system blowing very warm air right back into your home.

Should the evaporator coils be the issue, do not attempt to clean them on your own! This is the job for a trained professional, and evaporator coil cleaning is a common service offered during your annual AC maintenance service.

A Refrigerant Leak

Refrigerant leaks are not at all common, but they aren’t unheard of, either. Refrigerant leaks completely rob your cooling system of the ability to perform the refrigeration cycle, which is the technology that most cooling systems operate on. Should your system develop a leak, you’ll need to call a professional for AC repair. If you do spot a possible refrigerant leak, it’s best to call for service right away. While most toxic refrigerants are being phased out (such as R-22), many refrigerants that are still found in Florida homes can be harmful if you come into contact with them unprotected.
