The Five Most Common Air Conditioning Problems Livermore Homeowners Face

January 30, 2015

Although there may be hundreds of factors why your Livermore home’s central air conditioner may need to be looked at by a certified contractor, there are a few reasons that are most common. Identifying them may create some personal understanding what a technician means when they discuss 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 AC wiring

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

  2. Your Air Conditioner is Low on refrigerant

    Refrigerant (also known as Freon) is the chemical that cools the air in your air conditioning system. Low refrigerant could imply a leak or problem with the refrigerant system. If your air conditioning system needs to be recharged with refrigerant, typically that means there is a leak. All refrigerant leaks should be detected 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 AC fan is not operating

    The fan on your outside AC unit is responsible for moving the heat from your Livermore home to the outside air. If the fan on the outside unit doesn’t operate properly, proper heat transfer is not taking 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 air conditioner unit not functional

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

  5. Frozen inside coil

    A frozen coil typically indicates a problem with the airflow, such as restrictions caused by old air filters or obstructed return air ductwork. Frozen indoor coils could also be caused by low refrigerant.

Experts recommend that the most effective way for a Livermore area homeowner to prevent these expected problems is by participating in a preventive maintenance program. Bad wiring, low refrigerant and airflow problems can be discovered during routine maintenance tune-ups. For all these common issues, a professionally qualified, NATE-certified technician can promptly diagnose the problem area and apply the necessary repairs. Call or contact us today for an evaluation!
