What to Do When Your Air Conditioning Won’t Turn On?

September 5, 2019

It can be extremely frustrating when your air conditioning unit won’t turn on. Here are some troubleshooting tips to help you get it working again.

1. Check the Thermostat

It is important to determine if there is power to the thermostat and that the thermostat is set to COOL mode. Note that the temperature setting on the thermostat should also be lower than the actual room temperature, or the AC will not turn on even if everything else is functioning properly.

2. Check Your Air Filter

The air filter in your AC needs to be changed out every three months. If the air filter gets clogged, it could cause the AC to turn off or freeze up.

3. Check the Main Power Panel

The AC circuit breaker may have been switched off due to a power surge. Without power from the main source, your AC will not turn on.

4. Check Your AC Drain Pan

Your AC has a float switch in the drain pan that can be triggered off if the pan becomes too full or gets clogged. The pan is located at the bottom of the AC.

5. Check Your AC Shut-Off Switch

Your AC usually has an ON/OFF switch like most other appliances in your home. If this switch is off, the AC will not be able to run.

What to Do If the Above Steps Fail

You may not be able to get your AC to turn on even after you have followed all the steps above. Some issues that cause your AC not to run are more complicated and require the help of a professional technician.
