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

January 30, 2015

Although there may be hundreds of factors why your Belleville home’s central air conditioner may need to be looked at by a certified contractor, there are several reasons that are fairly common. Knowing what they are may help you to understand what a technician is referring to when they outline the routes for resolving the problem. Here are the top 5 list of 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 wiring

    Shotty, haphazard or uncertified A/C wiring is unsafe and a possible fire hazard. Bad wiring may stop the system from getting power or can trip the circuit breaker.

  2. Depleted refrigerant

    Refrigerant (typically referred to as Freon) is the chemical that cools the air within your air conditioning system. depleting levels of refrigerant could 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 insinuates there is a leak. All refrigerant leaks should be found and repaired.

  3. Outside fan is not functioning

    The fan on your outside AC unit is responsible for moving the heat from your Belleville 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. This action can lead to 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 often indicates trouble 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.

Experts recommend that the number one way for a Belleville area homeowner to prevent these simple problems is by participating in a preventive maintenance program. Bad wiring, low refrigerant and airflow problems can be detected during routine maintenance tune-ups.
