most common ac problems

When you just can’t seem to get out of the heat, there’s nothing worse than discovering that the air conditioner in your Edwardsville, IL, home isn’t working properly. Fortunately, we’ve got a list of the most common AC problems to help you diagnose your cooling system and get it back up and running.

Poor Maintenance

One of the most common air conditioner problems is simply poor maintenance. Keeping up with AC maintenance is crucial because it involves things like keeping the coils clean and the filter fresh. If you neglect this maintenance, it can be the direct cause of a lot of problems.

Refrigerant Leaks

In order for your AC to create cold air from seemingly nothing, it has to use a refrigerant. If this refrigerant begins to leak, your air conditioner won’t cool as well. An AC repair expert can identify and fix the leak and charge your system so it’s working at full capacity again. It’s important to have these leaks fixed by a professional because dealing with refrigerant without taking the proper precautions can pose mild dangers to you.

Sensor Problems

Air conditioners use sensors (or a thermostat if it’s a whole-house system) to measure air temperature. When these sensors aren’t working properly, your air conditioner won’t know when to kick on and will essentially not work. Fortunately, sensor problems can often be fixed without too much trouble.

Drainage Problem

Your air conditioner needs to drain itself of condensate to keep running, but the condensate drain pan and drain line can become clogged over time. If your air conditioner isn’t draining properly, you’ll notice a pool of water in the condensate drain pan. For room air conditioners, they should be installed level to ensure proper drainage.

Electric Problems

While a lot of air conditioner problems seem to result from poor maintenance or something preventable, there are some things that just tend to happen over time. Electrical problems are one of these things. If your AC has a seemingly unidentifiable problem and isn’t working, it may be something to do with the electrical system.

The last thing you want is to be stranded on a hot day with no air conditioning. As long as you keep up with AC maintenance, that shouldn’t be a problem. If you do have an issue, call an HVAC technician for AC repair to get it fixed as soon as possible.

  • Thomas Peterson You made a good point that refrigerant is needed for your ac to work well. I have noticed that my ac has been leaking refrigerant and it hasn't been working very well. Maybe an ac repair would be helpful to get it working well again. Reply
