Why Is My Home Air Conditioner Blowing Hot Air?
If you’re wondering, “why is my AC blowing hot air?” you’re not alone. When your air conditioner fails to provide the cool, refreshing air you expect—especially in hot climates like Florida—it can be frustrating and uncomfortable. Several common issues could be behind your AC blowing warm or hot air instead of cooling your home.
In this overview, we’ll explain the most frequent causes and offer troubleshooting tips to help you restore your home’s comfort. Whether it’s a minor fix or something that needs professional attention, addressing the problem quickly is essential.
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.
