Although there are potentially hundreds of 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. Identifying them may help you to understand 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.
- Faulty AC wiring
Improper, haphazard or uncertified A/C wiring is dangerous and a potential fire hazard. Bad wiring may stop the system from getting power or can trip the circuit breaker.
- Your Air Conditioner is Low on refrigerant
Refrigerant (more commonly referred to as Freon) is the chemical that cools the air inside your air conditioning system. depleting levels of refrigerant could 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 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. The consequence of this action could result in internal damage to the compressor.
- Outside air conditioner unit not functional
This usually indicates a loss of power, contactor problems or even a faulty thermostat.
- Frozen coil
A frozen coil often indicates trouble with the airflow, such as restrictions caused by dirty air filters or obstructed return air ductwork. Frozen indoor coils could also be caused by low refrigerant.
