Electrical Faults Short cycling can also be caused by electrical problems. Sometimes the capacitor or electric supply cable may have faults, or the AC may have electrical faults such can come from the circuits board or even the thermostat; any of these problems can cause the AC unit to turn on and off repeatedly.

Does air conditioning heat as well as cool? This depends on the particular unit you have installed in your home. If your AC is also designed to work as a heat pump, then you can use your existing unit to heat your space too. If you've got an HVAC system, this also indicates that your aircon has a heating ability.
