Common Causes

Equipment that is oversized for the home
A dirty air filter or coil
A thermostat placed somewhere that does not reflect the whole home's temperature, like near a vent or in direct sun
Low refrigerant
Electrical or capacitor issues causing the compressor to stop and restart
A frozen coil beginning to thaw and refreeze

What You Can Safely Check

Check and replace the air filter if it is dirty
Note how many minutes the system runs before stopping and how long it stays off between cycles
Check where the thermostat is located and whether it is exposed to a vent, sunlight, or a drafty area

FAQ

AC Short Cycling Questions

What is short cycling?

Short cycling is when the AC turns on and off more frequently than normal, often running for just a few minutes at a time instead of completing a full cooling cycle.

Why is short cycling bad?

It wastes energy, adds wear to the compressor and other components, and often leaves humidity behind because the system never runs long enough to dehumidify properly.

Can an oversized AC really cause this?

Yes. An AC that is too large for the home cools the air quickly and shuts off, then starts again shortly after — a sizing problem rather than a broken part.
