Air Conditioner Repair Tip: Common Cause of Short-Cycling
Air conditioning can make even the hottest summer bearable. If you live in Toronto or the surrounding area, you know how important it is to keep your air conditioning system functioning effectively. If your air conditioning is turning on and off frequently, otherwise known as short-cycling, it is not only working inefficiently, but it is also wearing down its components quickly.
There are a few main causes of AC short-cycling, many of which are quick and easy fixes:
Refrigerant Leaks: Short-cycling can be caused by a leak in one of the refrigerant lines. While adding more refrigerant will temporarily fix the problem, you will need a professional to find and repair the leak. Only a certified professional should handle refrigerant, and they will be able to charge your unit with the correct amount after they fix the leak.
Ice on the Coils: If your cooling coil has ice or frost build-up, it can cause the unit to turn on and off rapidly. Turning off your AC and letting the ice melt can fix the problem, but you will want a professional to examine the system to find the underlying cause of the icing.
Oversize Air Conditioner: If your air conditioner has always short-cycled, it might be a result of your air conditioner being too large for your home. Bigger is not always better, and an air conditioner that is too large will cause uneven cooling and improper dehumidification as well as short-cycling. An air conditioning contractor can do a load calculation on your home to make sure you get the right unit for your home’s needs.
Control Board Problems: If your AC’s control board or a control switch has been damaged, it can cause erratic starting and stopping cooling cycles. An AC technician will be able to replace a broken board or switch.
While an air conditioner that is short-cycling is still functioning, it is both inefficient and ineffective.
