Why Is My Air Conditioner Running Constantly? 


An air conditioner is your best friend during a long summer day, and it comes in handy on those humid nights when you wake up to a stuffy bedroom. So despite how often the thing may be running, there are some reasons it might constantly be running. Here are 8 of them.

  1. Thermostat Is Not Working

The thermostat is the brain of the AC, so if this part of the system is not working, it could be causing the compressor to run constantly. The thermostat can be programmed to turn on and off at different times, depending on when you like your house cooler and warmer.

  1. Air Filter Is Dirty

A dirty air filter can affect both the operation of your home’s HVAC system and the efficiency of your system. At best, a clogged-up filter could increase energy consumption by more than 10%; at worst, it could make your AC run nonstop due to overheating.

  1. Coils Are Covered in Dirt

After a long winter, coils can get coated in dust, lint, and pet dander. As the AC starts blowing cool air around, some dirt is circulated back into the room. A dirty coil will consume energy and make your AC run constantly.

4.Air Leaks Are Present

A leaky air handler can cause the compressor to run constantly, especially if it is located in a high-traffic area. In some cases, this leaking air handler could use up to 50% of the energy it consumes – even when the house isn’t running.

5.Lack of Regular Maintenance

It’s easy to forget which service intervals you need to perform on your home’s HVAC system; however, this can lead to constant AC running. A cooling system that runs nonstop due to a lack of regular maintenance could consume 1000s of dollars in energy costs.

6.Improper Size 

Another reason could be that your air conditioning system might not work as designed because it is too small or large. This can cause an array of issues of varying degrees, including heat gain and loss. A house with a poorly sized system will also have to run continuously for the compressor to provide enough cooling.

7.Incorrect Programming or Installation

Some homeowners may have programmed or installed their air conditioning units incorrectly, allowing them to work nonstop when they should not be running at all. As long as these settings have not been corrected, an Ac will continue to run constantly and waste energy and money.

8.The AC Might Be Too Old and Need Replacement

If none of the above are the cause, it might be time to replace your Ac. As the home ages, it is more likely that cracks, holes, and other imperfections could develop in the system. Animats can cause the compressor to run constantly and not give your home as much cooling as possible.

In conclusion, there are many reasons your air conditioner may constantly be running, some of which are particularly dangerous. We Elite Air Conditioning got you if you have issues or require an Ac repair at a friendly and affordable price. Contact us today, and we can correct the problems.
