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

January 30, 2015

Although there are potentially hundreds of reasons why your Louisville home’s central air conditioner may need to be serviced, there are a couple of reasons that are most common. Recognizing what they are may clarify what a technician means when they address the routes 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. Bad wiring

    Improper, 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. Leaking refrigerant

    Refrigerant (typically referred to as Freon) is the chemical that cools the air inside your air conditioning system. Reduced levels of refrigerant usually will 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 encourage you to visit the U.S. EPA website.

  3. Outside fan is not turning

    The outside fan is responsible for conveying the heat from your Louisville 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. Worse yet, it may cause 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. The coil is frozen

    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 caused by 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 promptly review the problem area and apply the necessary repairs. Call or contact us today for an evaluation!
