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

January 30, 2015

While there may be endless reasons why your Birmingham home’s central air conditioner may need to be repaired, there are a few reasons that are most common. Knowing what they are may help you to understand what a technician is saying when they discuss the routes for correcting the problem. Here are the top five problems that may cause your air conditioning system to break down. Please review these considerations and determine whether you need to schedule an HVAC inspection.

  1. Faulty wiring

    Incorrect, haphazard or uncertified A/C wiring is risky and a potential fire hazard. Bad wiring may stop 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. Low refrigerant may imply 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 encourage you to visit the U.S. EPA website.

  3. Outside fan is not functioning

    The fan on your air conditioner outside is responsible for transferring the heat from your Birmingham home to the outside air. If the fan on the outside unit doesn’t operate properly, 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 unit not functional

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

  5. Frozen coil

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

Best practices suggest that the most convenient way for a Birmingham 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 analyze the problem area and implement the necessary repairs.
