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

January 30, 2015

Although there may be hundreds of factors why your Charleston 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 help you to understand what a technician is referring to when they address the choices for correcting the problem. Here are the 5 most common problems that may result in a system’s failure. Review the Top 5 list below and if any of these scenarios exist in your home, please schedule an HVAC inspection.

  1. Bad wiring

    Bad, 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. Leaking refrigerant

    Refrigerant (more commonly referred to as Freon) is the chemical that cools the air within your air conditioning system. Reduced levels of refrigerant may suggest a leak or problem with the refrigerant system. If your air conditioning system needs to be recharged with refrigerant, typically that insinuates 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 functioning

    The fan on your air conditioner outside is responsible for conveying the heat from your Charleston 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 typically indicates a loss of power, contactor problems or even a bad thermostat.

  5. The coil is frozen

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

Best practices suggest that the number one way for a Charleston area homeowner to prevent these expected problems is by participating in a preventive maintenance program. Bad wiring, low refrigerant and airflow problems can be detected during routine maintenance tune-ups. For all these common issues, a professionally qualified, NATE-certified technician can promptly review the problem area and make the necessary repairs. Call or contact us today for an evaluation!
