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

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 most common. Knowing what they are may help you to understand what a technician means when they outline the choices for correcting the problem. Here are the 5 most common 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 wiring

    Improper, haphazard or uncertified A/C wiring is risky and a possible fire hazard. Bad wiring can prevent 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 may indicate 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 detected 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 fan is not operating

    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 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 typically indicates a loss of power, contactor problems or even a broken thermostat.

  5. Frozen inside coil

    A frozen coil often indicates a problem 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 quickly diagnose the problem area and implement the necessary repairs.
