How Does an AC Compressor Work?

Your compressor unit is the heart of your air conditioning system. It’s responsible for pumping refrigerant through your AC and maintaining adequate pressure levels. When something goes wrong with your compressor, it could cause your entire system to stop working.

Common AC Compressor Problems

Because your compressor is such a central part of your AC, there are a lot of different things can go wrong with it. Here’s a look at some of the most common compressor related issues and how to troubleshoot for them.

1. Overuse of your AC system

It’s very important that your compressor maintains adequate pressure levels. When your system has to strain itself to keep up, pressure level may be thrown off. Most air conditioning systems have switches that will shut the system off automatically if the pressure gets too high or too low. When your compressor stops working, these switches are a good place to start. If they’ve been switched off, you know the problem is a result of inadequate pressure. Your system might start working fine again when you turn it back on, but you’ll want to call a professional AC technician if the problem persists.

2. AC Refrigerant Leaks

Refrigerant enters your compressor as a cool, low-pressure gas, which keeps the motor running at the right temperature. If your system has a refrigerant leak and there is not enough refrigerant cycling into the compressor, the motor may overheat. This can cause your system to stop working. Refrigerant leaks are serious issues so if you suspect this issue, contact a professional AC technician for a repair right away.

3. Electrical or Power Problems

If your compressor is frequently switching on and off, it may the result of a faulty electrical connection or a frayed wire. Electrical issues can also cause your compressor motor to overheat. If you think your AC is experiencing an electrical issue, it’s best to leave things to the professionals, as electrical work can be dangerous!

4. Improper AC System Size

Whether your system is too big or too small, an improperly sized AC will wear down your compressor, putting it at greater risk of breaking down.

An oversized AC system will short cycle, causing your system to constantly shut on and off.

An undersized AC system will have to run longer to cool your home.

Both issues put great strain on your compressor and can lead to damage and overheating.
