Why Is My Air Conditioner Running All the Time?

May 7, 2015

When your air conditioner is functioning properly it should cycle on-and-off occasionally to keep your home cool and comfortable. Your AC system will cycle on when temperatures inside your home are hotter than you set your thermostat to. Once the desired temperature is reached your air conditioner should cycle off, but, that’s not always the case.

If you find your air conditioner is running all the time without cycling on or off, chances are the unit is malfunctioning and probably needs to be repaired by an HVAC professional. Below, we’ve outlined a few reasons why your air conditioner runs all the time:

To make up for the lack of cooling capacity you may find your air conditioner running all the time without cycling off.

Air or Duct Leaks
