AC Not Working? Here are some Common AC Problems in West Chester

January 30, 2015

Although there may be hundreds of factors why your West Chester home’s central air conditioner may need to be looked at by a certified contractor, there are a few reasons that are quite common. Knowing what they are may help you to understand what a technician is referring to when they discuss the options for correcting the problem. Here are the 5 most common problems that may cause your air conditioning system to break down. Review the Top 5 list below and if any of these scenarios exist in your home, please schedule an HVAC inspection.

  1. Bad wiring

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

  2. Depleted refrigerant

    Refrigerant (also known as Freon) is the chemical that cools the air in 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. 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 turning

    The fan on your air conditioner outside is responsible for moving the heat from your West Chester home to the outside air. If the fan on the outside unit doesn’t perform correctly, proper heat transfer does not occur and the air conditioning compressor may overheat and trip the safety overload. Worse yet, it may cause internal damage to the compressor.

  4. Outside unit not functional

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

  5. Frozen inside coil

    A frozen coil mainly 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 derived from low refrigerant.

Best practices suggest that the number one way for a West Chester area homeowner to prevent these common problems is by participating in a preventive maintenance program. Bad wiring, low refrigerant and airflow problems can be uncovered during routine maintenance tune-ups.
