The Five Most Common Air Conditioning Problems Louisville Homeowners Face

January 30, 2015

Although there are potentially hundreds of reasons why your Louisville home’s central air conditioner may need to be repaired, there are a couple of reasons that are quite common. Recognizing what they are may clarify what a technician means when they address the options for resolving the problem. Here are the top five problems that may cause your AC unit to fail. Review the Top 5 list below and if any of these scenarios exist in your home, please schedule an HVAC inspection.

  1. Faulty AC wiring

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

  2. Your Air Conditioner is Leaking refrigerant

    Refrigerant (typically referred to as Freon) is the chemical that cools the air in your air conditioning system. Low refrigerant may imply a leak or problem with the refrigerant system. If your air conditioning system needs to be recharged with refrigerant, 90% of the time that suggests there is a leak. All refrigerant leaks should be located and repaired. To learn 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 AC fan is not turning

    The fan on your outside AC unit is responsible for transferring the heat from your Louisville home to the outside air. If the fan on the outside unit doesn’t perform correctly, 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 lack of power, contactor problems or even a faulty thermostat.

  5. Frozen inside coil

    A frozen coil mainly indicates trouble with the airflow, such as restrictions caused by dirty air filters or collapsed return air ductwork. Frozen indoor coils could also be the result of low refrigerant.

Best practices suggest that the most convenient way for a Louisville area homeowner to prevent these expected problems is by participating in a preventive maintenance program. Bad wiring, low refrigerant and airflow problems can be uncovered 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!
