Although there are potentially hundreds of reasons why your Birmingham home’s central air conditioner may need to be serviced, there are a couple of reasons that are most common. Identifying them may help you to understand what a technician is saying when they discuss the routes for correcting 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
Incorrect, 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 Low on refrigerant
Refrigerant (more commonly 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, 90% of the time that insinuates there is a leak. All refrigerant leaks should be detected and repaired. For news about the phase out of R-22 refrigerant in the United States, we highly recommend 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 Birmingham 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. This action can lead to internal damage to the compressor.
- Outside air conditioner unit not functional
This usually indicates a loss of power, contactor problems or even a bad thermostat.
- Frozen coil
A frozen coil typically indicates an issue 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 convenient way for a Birmingham area homeowner to prevent these expected problems is by participating in a preventive maintenance program. Bad wiring, low refrigerant and airflow problems can be found during routine maintenance tune-ups. For all these common issues, a professionally qualified, NATE-certified technician can quickly diagnose the problem area and implement the necessary repairs.
