In the summer heat, the last thing you want is for your air conditioner to start short-cycling. Unfortunately, this common problem can leave your home feeling hot and sticky.

So, what is short-cycling? Short-cycling occurs when your air conditioner turns on and off too frequently. This can happen for several reasons as your air conditioner is made up of many different parts all need to work together seamlessly.

  1. One common reason for short-cycling is a dirty air filter. A dirty air filter restricts air flow, causing your air conditioner to work harder than it needs to. This can lead to the unit over-heating and shutting off prematurely. Checking your air filter monthly and changing it when it’s dirty is a simple way to help prevent short-cycling.
  2. Another common cause of short-cycling is a faulty thermostat. If your thermostat isn’t working properly, it may not be sending the correct signal to your air conditioner, causing it to cycle on and off more frequently than necessary.

  4. Another potential cause of short-cycling is a refrigerant leak. Your air conditioner needs the right amount of refrigerant to work properly . If there’s a leak, the refrigerant level can drop, causing your air conditioner to cycle on and off more frequently. This is a job for a professional as it can be dangerous to try to fix a refrigerant leak yourself.
  5. Lastly, your air conditioner may be short-cycling because of a problem with the fan. The fan circulates air over the evaporator coils. If the fan isn’t working correctly, the air conditioner will overheat and shut off. This is another issue that should be diagnosed by a professional.
