Although there are potentially hundreds of reasons why your Charlotte home’s central air conditioner may need to be repaired, there are a few reasons that are quite common. Identifying them may help you to understand what a technician means when they discuss the routes for resolving the problem. Here are the 5 most common problems that may cause your AC unit to fail. Check out the list below and consider whether your home has any of these issues. If so, schedule an HVAC inspection.
- Bad AC wiring
Incorrect, haphazard or uncertified A/C wiring is dangerous and a possible 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 (typically referred to as Freon) is the chemical that cools the air in your air conditioning system. Low refrigerant may imply a leak or problem with the refrigerant system. If your air conditioning system needs to be recharged with refrigerant, usually that insinuates there is a leak. All refrigerant leaks should be found and repaired. To learn 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 working
The fan on your air conditioner outside is responsible for moving the heat from your Charlotte 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.
- Outside air conditioner unit not functional
This usually indicates a loss of power, contactor problems or even a faulty thermostat.
- Frozen inside coil
A frozen coil mainly indicates a problem with the airflow, such as restrictions caused by old air filters or blocked return air ductwork. Frozen indoor coils could also be derived from low refrigerant.
Experts recommend that the number one way for a Charlotte area homeowner to prevent these expected problems is by participating in a preventive maintenance program. Bad wiring, low refrigerant and airflow problems can be discovered during routine maintenance tune-ups.
