The Five Most Common Air Conditioning Problems Concord Homeowners Face

January 30, 2015

Although there may be hundreds of factors why your Concord home’s central air conditioner may need to be repaired, there are several reasons that are fairly common. Knowing what they are may create some personal understanding what a technician is referring to when they discuss the choices for resolving the problem. Here are the top five 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. Faulty AC wiring

    Incorrect, haphazard or uncertified A/C wiring is risky and a probable fire hazard. Bad wiring often prevents the system from getting power or can trip the circuit breaker.

  2. Your Air Conditioner is Low on refrigerant

    Refrigerant (more commonly referred to as Freon) is the chemical that cools the air in your air conditioning system. Reduced levels of refrigerant usually will imply a leak or problem with the refrigerant system. If your air conditioning system needs to be recharged with refrigerant, usually 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 functioning

    The fan on your outside AC unit is responsible for transferring the heat from your Concord 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. This action can lead to internal damage to the compressor.

  4. Outside air conditioner unit not functional

    This often indicates a significant reduction of power, contactor problems or even a faulty 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.

Experts recommend that the most convenient way for a Concord area homeowner to prevent these simple 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 analyze the problem area and make the necessary repairs. Call or contact us today for an evaluation!
