AC Not Working? Here are some Common AC Problems in Mint Hill

January 30, 2015

While there may be endless reasons why your Mint Hill home’s central air conditioner may need to be repaired, there are a few reasons that are most common. Knowing what they are may help you to understand what a technician means when they discuss the routes for resolving the problem. Here are the 5 most common problems that may cause your AC unit to fail. Check out the list below and consider whether your home has any of these issues. If so, schedule an HVAC inspection.

  1. Bad wiring

    Incorrect, haphazard or uncertified A/C wiring is dangerous and a possible 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 in your air conditioning system. Reduced levels of refrigerant may 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 found and repaired. For news 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 air conditioner outside is responsible for moving the heat from your Mint Hill home to the outside air. If the fan on the outside unit doesn’t run, proper heat transfer does not occur 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 broken thermostat.

  5. Frozen inside coil

    A frozen coil mainly indicates a problem with the airflow, such as restrictions caused by old air filters or obstructed return air ductwork. Frozen indoor coils could also be derived from low refrigerant.

Experts recommend that the number one way for a Mint Hill 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 promptly diagnose the problem area and make the necessary repairs. Call or contact us today for an evaluation!
