The Five Most Common Air Conditioning Problems Nashville Homeowners Face

January 30, 2015

Although there are potentially hundreds of reasons why your Nashville home’s central air conditioner may need to be looked at by a certified contractor, there are a few reasons that are most common. Recognizing what they are may help you to understand what a technician is referring to when they discuss the options for resolving the problem. Here are the 5 most common problems that may cause your air conditioning system to break down. Check out the list below and consider whether your home has any of these issues. If so, schedule an HVAC inspection.

  1. Bad AC wiring

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

  2. Your Air Conditioner is Low on refrigerant

    Refrigerant (typically referred to as Freon) is the chemical that cools the air in 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 AC fan is not operating

    The outside fan is responsible for conveying the heat from your Nashville home to the outside air. If the fan on the outside unit doesn’t run, proper heat transfer cannot take 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 air conditioner unit not functional

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

  5. The coil is frozen

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

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