Air conditioning can be a real lifesaver when it’s working, and a sweaty headache when it’s not. Central air conditioning is a staple of most homes in the United States, but the more advanced the system gets, the harder it is to repair on your own. If you’re thinking about trying to fix your home air conditioning system on your own, it helps to understand how it all works.
If you’re dead set on trying it yourself, however, here’s a quick look at some common problems with central AC units, and how you might be able to fix them.

My Air Conditioner Repair

If the air conditioning system won’t fire up at all, it might be an issue with a faulty fuse or a circuit breaker, but it could also be one of the internal safety features, like a thermostat that’s giving the wrong readings or one of the internal switches that’s stuck in the “off” position.

How to Fix Air Conditioner Repair:First of all, check to make sure that the thermostat is on. It sounds silly, but you would be surprised how many people don’t think to check this. If the thermostat is set to heating, or off completely, the air conditioner definitely won’t be pumping out cool air.

You should also make sure that the thermostat’s target temperature is below the current room temperature, because anything at or above room temperature won’t trigger the central air conditioning system to start.

If none of these are the cause of the problem, it could be a problem with the double breaker that regulates the condensing/compressor unit. If the breaker overloads it will pop into the off position, but it could also be a blown fuse. In these cases, you can try resetting the breaker or replacing the fuse. If you do this, but the same thing happens again, you should contact an air conditioning repair service because the problem could be more serious.

There’s No Cool Air Coming Out Of My Vents!

If your home air conditioning system is definitely on, but isn’t sending cool air through the vents in your house, it’s most likely a problem with either the air filter or the cooling ducts.

First, check the air filter to make sure it’s not clogged. You should replace this regularly, because it’s trapping all the tiny specks of dust that normally float through the air so that they don’t circulate through your house. A clogged air filter puts extra strain on the system and can lower the operating lifespan of your home air conditioner.

If cleaning or replacing the filter doesn’t fix the problem, inspect all the cooling ducts for anything that might have become disconnected. Common places to find cooling ducts are in the basement, attic, and any crawl spaces. This information about air conditioner repair will get you started in the right direction.
