Why do air conditioning units freeze?
September, 28th, 2012
There is nothing worse than sitting inside your home on a hot summer day and your air conditioner quits working. The two most common reasons for an air conditioning unit to freeze up is lack of air due to dirty air filters or coils and low refrigerant, most commonly known as Freon.
Dirty air filters or coils will obstruct the air flow of the unit causing it to overwork its self until the unit freezes up and quits working. If your air filter or coils are dirty sometimes all it takes to get your air conditioner working again is to get them clean. You can do this yourself or hire a certified HVAC technician do it for you.
Low Freon or refrigerant can cause your air conditioning unit to get stuck in the on position. If this happens, the ac unit will not shut off until it freezes up. If you have low Freon, it is most often caused by a leak. Freon leaks can be difficult to detect, especially if it is a small leak. If you determine that your Freon is low, you should contact a certified HVAC professional to identify, fix the problem and recharge your unit.
The best way to prevent your air conditioning unit from freezing up on you is to have it serviced annually by a professional air conditioning contractor. Annual service is the most cost effective way to keep your air conditioning unit running at peak proficiency.
