The Five Most Common Air Conditioning Problems Gaithersburg Homeowners Face

January 30, 2015

Although there may be hundreds of factors why your Gaithersburg home’s central air conditioner may need to be repaired, there are a couple of reasons that are quite common. Identifying them may create some personal understanding what a technician is referring to when they address the choices for fixing the problem. Here are the top five 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. Wrong AC wiring

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

  2. Your Air Conditioner is Low on refrigerant

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

  3. Outside AC fan is not working

    The fan on your air conditioner outside is responsible for moving the heat from your Gaithersburg 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 air conditioner unit not functional

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

  5. The coil is frozen

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

Experts recommend that the number one way for a Gaithersburg 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 diagnose the problem area and implement the necessary repairs.
