It is just too hot outside. You are trying to get some much needed relief from the heat, but your ac can’t turn on. What do you do? There are many reasons why an AC might not start up in this situation, and we have compiled a list of the most common ones in detail below!
Refrigerant leak
A refrigerant leak happens when the system has lost some of its gases. If this is the case, you need to call in a professional repairman who can repair it for you.
Tripped breaker or blown fuse
The AC unit may have been working hard and tripped the breaker or blown the fuse. Check your breaker box and/or fuse box to see if this is the problem.
Dirty air filter
The air filter may be dirty, clogged, or blocked. This will prevent the AC unit from working properly. Be sure to clean or replace the air filter as needed.
Thermostat issues
If the thermostat isn’t working properly, the AC unit will not turn on. Make sure that the thermostat is set to “cool” and is in the right mode. Also, check to make sure that it is not in “off” mode.
Weak compressor
A weak compressor might be causing your AC unit not to work and turn on. If this is the case there isn’t much that you can do, you will just need to wait for your compressor to start working again before using your air conditioner.
Lack of refrigerant
There might not be enough refrigerant in the system causing it to stop working. You can check with a professional about getting some more added if needed.
Outdoor unit issues
The outdoor AC unit might have run into some trouble. This could be anything from a power outage to a bad capacitor or motor. For any other possible problems visit our article on finding out why an AC won’t turn off.
