When your AC is running properly, the compressor is controlled by the thermostat. It signals the compressor to power up and runs until the designated temperature is reached, then it signals the compressor to stop. If you have noticed that the unit is powering on and off very frequently regardless of what the thermostat reads, your HVAC unit is likely experiencing something called short cycling. Oddly enough, short cycling is a symptom of problems and the cause of even more problems. It’s just one of the reasons why you would need Air 24/7 Air Conditioning & Heating repair near me.

What is Short-Cycling?

Short cycling occurs when the compressor shuts off before it has completed a full cooling cycle, but because the thermostat hasn’t detected the correct temperature, it signals the compressor to start up again. The compressor starts up but will shut itself off again too soon. This pattern causes a lot of unnecessary wear and tear on the HVAC unit that will result in other problems and the premature replacement of the system.

Causes of Short-Cycling

Culprits that cause short cycling include:

  • leaks in the ventilation system,
  • low refrigerant levels,
  • an HVAC unit that is too large or too small for the space,
  • thermostats that have been incorrectly calibrated, and
  • clogged air filters.

Replacing the air filter is something that homeowners can do but the other problems require the expertise of a professional HVAC technician.

Results of Short-Cycling

Since the compressor is essentially stuck in the start-up mode, it must be repaired before it causes more serious problems. A unit that is short cycling will use more power resulting in higher energy bills and running the risk of overheating and burning out completely.


The best way to keep your HVAC system running properly when you need it the most is to have it inspected yearly. This gives qualified technicians the chance to diagnose any problems and fix them before they become major issues.
