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

January 30, 2015

Although there may be hundreds of factors why your Dublin home’s central air conditioner may need to be looked at by a certified contractor, there are a few reasons that are quite common. Knowing what they are may create some personal understanding what a technician means when they discuss the options for resolving the problem. Here are the top five problems that may cause your AC unit to fail. Please review these considerations and determine whether you need to schedule an HVAC inspection.

  1. Faulty wiring

    Shotty, haphazard or uncertified A/C wiring is risky and a probable fire hazard. Bad wiring often prevents the system from getting power or can pop the circuit breaker.

  2. Low refrigerant

    Refrigerant (more commonly referred to as Freon) is the chemical that cools the air inside your air conditioning system. Reduced levels of refrigerant could imply a leak or problem with the refrigerant system. If your air conditioning system needs to be recharged with refrigerant, usually that means there is a leak. All refrigerant leaks should be detected and repaired. For news about the phase out of R-22 refrigerant in the United States, we highly recommend you to visit the U.S. EPA website.

  3. Outside fan is not working

    The outside fan is responsible for moving the heat from your Dublin home to the outside air. If the fan on the outside unit doesn’t operate properly, proper heat transfer cannot take 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 typically indicates a loss of power, contactor problems or even a bad thermostat.

  5. Frozen inside coil

    A frozen coil typically indicates an issue with the airflow, such as restrictions caused by old air filters or obstructed return air ductwork. Frozen indoor coils could also be caused by low refrigerant.

Experts recommend that the number one way for a Dublin area homeowner to prevent these expected problems is by participating in a preventive maintenance program. Bad wiring, low refrigerant and airflow problems can be discovered during routine maintenance tune-ups. For all these common issues, a professionally qualified, NATE-certified technician can quickly analyze the problem area and apply the necessary repairs. Call or contact us today for an evaluation!
