Why Is My Air Conditioner Running All the Time? - Rick's Heating and Cooling

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:

Reasons Why Your AC Runs All the Time

Open Windows & Doors

A simple solution to stopping your air conditioner from constantly running is to shut all open windows and/or doors. Be sure to check all extra bedroom windows, patio or screen doors, bathroom windows, etc. If you have children, you should double check that their windows are closed when your air conditioner is running. Kids are well-known for opening windows because they are hot, then leaving the room and leaving them open and causing your air conditioner to run constantly.

Similarly, your thermostat might simply be set too low at a temperature your AC unit does not have capacity to meet.

Insufficient Capacity

When you hired an HVAC contractor to install your air conditioner, they should have performed a series of various tests to determine what sized air conditioner you need to effectively cool your home. If your air conditioning system is too small and does not have the cooling capacity to meet your demands, it simply won’t be able to keep up. 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

The air conditioner in your home should cycle off once it reaches your desired temperatures. But, if there are small holes in your home’s ductwork, the cool air traveling through your air ducts may not even reach its destination. So, how do you fix leaky air ducts? Call an HVAC professional!

The air filters in your heating and cooling system should be changed whenever they become dirty, which is typically around 90 days.
