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

January 30, 2015

While there may be endless reasons why your Nashville home’s central air conditioner may need to be looked at by a certified contractor, there are a couple of reasons that are quite common. Recognizing what they are may help you to understand what a technician means when they discuss the options for resolving the problem. Here are the top five problems that may result in a system’s failure. Check out the list below and consider whether your home has any of these issues. If so, schedule an HVAC inspection.

  1. Faulty wiring

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

  2. Leaking refrigerant

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

  3. Outside fan is not operating

    The fan on your outside AC unit is responsible for transferring the heat from your Nashville home to the outside air. If the fan on the outside unit doesn’t run, proper heat transfer is not taking place and the air conditioning compressor may overheat and trip the safety overload. The consequence of this action could result in internal damage to the compressor.

  4. Outside unit not functional

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

  5. Frozen inside coil

    A frozen coil typically indicates trouble 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.

Best practices suggest that the most effective way for a Nashville area homeowner to prevent these simple 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 review the problem area and apply the necessary repairs. Call or contact us today for an evaluation!
