Why is My AC Blowing Hot Air?

Summer is time to enjoy cooling off by the pool or lake, but remember that while you are relaxing your AC is running all day. What happens when suddenly your air conditioning unit starts blowing hot air?

Here are a few things that you should check:

Your Thermostat

Sometimes the simplest explanations are the hardest to see. It is a common mistake that the thermostat is set incorrectly. Similarly, check the ‘auto’ setting or if the fan is set to ‘on’. This means the fan will run even if the AC is not set to cool.

Airflow Restriction/Clogged Air Filter

When was the last time you changed your air filter? The air filter protects your unit by filtering out dirt and debris from the air. If the filter is doing its job the way it is supposed to, it will collect dirt and debris and need to be replaced regularly. Neglecting to change these according to your manufacturer’s recommendation can result in decreased cooling power.

Inside and Outside Units Turned On and In Good Repair

Your AC unit needs both an inside and an outside unit to operate. The inside unit has a fan that blows air through the house and needs the outside unit to provide cool air for it to push around. Check if both your inside and outside units are turned on and functioning properly. Check the outside unit for ice which can cause a malfunction in the compression coil, hence the warm air. Also double check that your coils aren’t dirty as this can be another cause for warm air.

Other more troublesome problems include refrigerant leaks, bad compressors and/or electrical problems and failures. These problems require a professional to diagnose and fix. Refrigerant leaks can be dangerous, and compressors are complicated and can often be misdiagnosed if inspected by someone unqualified to do so.
