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

January 30, 2015

While there may be endless reasons why your Charlotte home’s central air conditioner may need to be repaired, there are several reasons that are most common. Recognizing what they are may help you to understand what a technician means when they discuss the choices for resolving the problem. Here are the top 5 list of 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 can prevent the system from getting power or can trip the circuit breaker.

  2. Low refrigerant

    Refrigerant (also known as Freon) is the chemical that cools the air inside 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, 90% of the time that means there is a leak. All refrigerant leaks should be detected and repaired. For news 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 fan is not working

    The fan on your outside AC unit is responsible for moving the heat from your Charlotte 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 unit not functional

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

  5. Frozen inside coil

    A frozen coil often indicates an issue with the airflow, such as restrictions caused by filthy 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 Charlotte area homeowner to prevent these common problems is by participating in a preventive maintenance program. Bad wiring, low refrigerant and airflow problems can be found during routine maintenance tune-ups. For all these common issues, a professionally qualified, NATE-certified technician can efficiently diagnose the problem area and implement the necessary repairs.
