AC Not Working? Here are some Common AC Problems in Phoenix

January 30, 2015

Although there may be hundreds of factors why your Phoenix home’s central air conditioner may need to be repaired, there are a few reasons that are most common. Recognizing what they are may help you to understand what a technician is saying when they address the options for correcting the problem. Here are the top five problems that may result in a system’s failure. Please review these considerations and determine whether you need to schedule an HVAC inspection.

  1. Wrong wiring

    Shotty, haphazard or uncertified A/C wiring is unsafe and a possible fire hazard. Bad wiring may stop the system from getting power or can trip the circuit breaker.

  2. Low refrigerant

    Refrigerant (also known as Freon) is the chemical that cools the air inside your air conditioning system. Low refrigerant could indicate a leak or problem with the refrigerant system. If your air conditioning system needs to be recharged with refrigerant, usually that suggests there is a leak. All refrigerant leaks should be found and repaired. To learn about the phase out of R-22 refrigerant in the United States, we suggest that you to visit the U.S. EPA website.

  3. Outside fan is not turning

    The fan on your air conditioner outside is responsible for moving the heat from your Phoenix home to the outside air. If the fan on the outside unit doesn’t perform correctly, proper heat transfer is not taking place and the air conditioning compressor may overheat and trip the safety overload. Worse yet, it may cause internal damage to the compressor.

  4. Outside unit not functional

    This usually indicates a lack of power, contactor problems or even a broken thermostat.

  5. Frozen coil

    A frozen coil typically indicates a problem with the airflow, such as restrictions caused by filthy air filters or collapsed return air ductwork. Frozen indoor coils could also be caused by low refrigerant.

Best practices suggest that the most effective way for a Phoenix area homeowner to prevent these simple problems is by participating in a preventive maintenance program. Bad wiring, low refrigerant and airflow problems can be detected during routine maintenance tune-ups. For all these common issues, a professionally qualified, NATE-certified technician can promptly analyze the problem area and implement the necessary repairs.
