3 Reasons the AC could Overheat this Summer

An overheated, non-running air conditioner is the last thing any homeowner wants to come home to on a hot afternoon. When the AC overheats, it often trips the circuit breaker continually until the problem is solved. Instead of coming home to a hot, stuffy house, learn how to deal with the three most common reasons the AC overheats.

  1. Dirty Filter

When the air filter gets too dirty, it will clog and begin to restrict airflow. This means the air conditioner has to work even harder to try and cool the home. This overexertion can cause to air conditioner to overheat and trip the breaker.

  1. Dirty Coils

When the hot liquid refrigerant flows to the outside world to discharge the heat, it needs to be able to release the heat easily. Dirt-covered condenser coils make that much more difficult because dirt acts as an insulator. The AC then has a more difficult time reaching the desired temperature set by the thermostat and will continuously run until it overheats.

  1. Low Refrigerant

If the refrigerant is low, the air conditioner will once again have troubles cooling the house down and may start to overheat. Keep an eye out for signs of low refrigerant such as:

  • Home isn’t being cooled as quickly
  • On very hot days, the house isn’t getting as cool
  • Outside unit is covered in ice

The problems above can be prevented easily with regular maintenance. The air filter should be changed a minimum of every three months. During the summer, homeowners should check the filter once a month to see if it is dirty because it is getting more use.
