Getting home from spending a day in the sun to an unexpectedly warm house is not an ideal situation. In fact, having your AC suddenly not working at any time is inconvenient at the very least. The good thing is that your air AC unit can usually be repaired. Waiting for a professional to come to fix it may leave you overheating and questioning why your AC’s not working. Having an idea of why your AC might not be working properly may help you avoid problems in the future.

Here are some of the most common reasons your AC is likely not working properly: 

Be sure it’s receiving power at the electrical panel

This one is pretty self-explanatory. If your AC unit isn’t working, you may want to check if it has been disconnected from the power source; or that there isn’t an issue with your power source.

The indoor disconnect switch is off

 If this is located in a more obscure place in your home, such as your attic or basement, it is possible that your indoor disconnect switch has been accidentally turned off. Ensure the disconnect switch is set to “on” before doing any troubleshooting- and hope that this is your answer!

Check your thermostat settings

Before you try to get to the possible reasons behind your AC isn’t working sufficiently, check your thermostat settings. If your unit isn’t working at all, it’s possible your thermostat batteries are dead. If your AC isn’t working sufficiently, switch it to heat or the fan setting, then switch it back to cooling. Wait a few minutes after the system kicks in, and hope that cool air comes rushing back.

You could have blown a fuse

If the fuse is blown you’ll need to replace the fuse between your AC and thermostat before you can get your air back up and running. This will require a professional to come to diagnose and fix the problem for you.

Check your return-air filter

This is especially important if you haven’t thought about your AC since last summer. It is possible that your return-air filters may be clogged and dirty. Therefore they are not allowing the cold air to blow through. Simply remove your return-air filter, and check if it is filled with debris. If it is filled too much to not see through the air filter – it is time for a replacement.
