While there may be endless reasons why your Raleigh 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 create some personal understanding what a technician is referring to when they discuss the choices for resolving the problem. Here are the 5 most common 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.
- Bad AC wiring
Bad, haphazard or uncertified A/C wiring is risky and a potential fire hazard. Bad wiring may stop the system from getting power or can short the circuit breaker.
- Your Air Conditioner is Leaking refrigerant
Refrigerant (also known as Freon) is the chemical that cools the air in your air conditioning system. depleting levels of refrigerant could indicate 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 located and repaired.

- Outside AC fan is not functioning
The outside fan is responsible for moving the heat from your Raleigh 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. Worse yet, it may cause internal damage to the compressor.
- Outside air conditioner unit not functional
This usually indicates a lack of power, contactor problems or even a broken thermostat.
- Frozen coil
A frozen coil typically indicates trouble with the airflow, such as restrictions caused by dirty air filters or obstructed return air ductwork. Frozen indoor coils could also be the result of low refrigerant.
