Most Common Arizona Air Conditioning Repairs

With summer right around the corner, home owners are preparing for the high temperatures of the desert heat. Home owners should test their Arizona air conditioning units to ensure they are working properly and ready to provide a safe haven for families. After months of nonuse several things may have happened to make your AC unit ineffective for the summertime, causing you to call for an Arizona air conditioning repair person. Some of the most common reasons for repair are included below.

Wiring Issues

Wiring issues are one of the most common reasons for an AC unit to need repairs. This is especially dangerous in the Arizona heat and could be a fire hazard for homes. Improperly installed wiring may prevent the unit from receiving power and cooling your home or in some cases, it can trip the circuit breaker, according to the Home Improvement blog on


Since the 1980’s, the refrigerant used in residential and light commercial air conditioning units was R-22 (commonly known as Freon) until the federal government banned its use due to concerns about depletion of the ozone layer. This ban prohibited the manufacturing of air conditioning units that used R-22 refrigerant effective January 2010. Since January 2010, the refrigerant used is R-410A.

Refrigerant is an odorless, colorless chemical that can leak and may be difficult to detect without proper training. Although the chemical is nonflammable, leaks can still be dangerous. The most obvious issue is that a lack of refrigerant will cause your unit to work harder to produce cold air and raise your energy bill.


Another common occurrence that will need repair is when the outside fan is not working properly. The fan works to remove hot air from the home and the unit. In the heat of summer an Arizona air conditioning unit without a properly working fan can overheat in a short amount of time. This can turn on the safety overload or potentially cause internal damage to the unit’s compressor.

Inside Coil

Finally, inside each AC unit is a coil. The coil contains the Freon which cools the air that is pumped throughout your home. Units in need of repair may develop a frozen coil. This can be caused by a number of things from an improper amount of Freon, to a blocked air duct. Traditionally AC repair professionals view a frozen coil as an indication of another problem.
