Although there may be hundreds of factors why your Charleston home’s central air conditioner may need to be repaired, there are a couple of reasons that are most common. Recognizing what they are may create some personal understanding what a technician is referring to when they address the choices for fixing the problem. Here are the 5 most common 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.
- 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 short the circuit breaker.
- Your Air Conditioner is Low on refrigerant
Refrigerant (more commonly referred to as Freon) is the chemical that cools the air within 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, usually that means there is a leak. All refrigerant leaks should be located 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.
- Outside AC fan is not functioning
The fan on your air conditioner outside is responsible for transferring the heat from your Charleston home to the outside air. If the fan on the outside unit doesn’t perform correctly, proper heat transfer cannot take 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 lack of power, contactor problems or even a bad thermostat.
- Frozen inside coil
A frozen coil typically 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 the result of low refrigerant.
Best practices suggest that the most effective way for a Charleston 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 quickly review the problem area and apply the necessary repairs. Call or contact us today for an evaluation!
