Although there may be hundreds of factors why your Concord home’s central air conditioner may need to be serviced, there are several reasons that are fairly common. Identifying them may help you to understand what a technician means 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 wiring
Incorrect, haphazard or uncertified A/C wiring is dangerous and a potential fire hazard. Bad wiring can prevent the system from getting power or can trip the circuit breaker.
- Low refrigerant
Refrigerant (more commonly referred to as Freon) is the chemical that cools the air in your air conditioning system. Reduced levels of 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 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 fan is not functioning
The fan on your outside AC unit is responsible for transferring the heat from your Concord home to the outside air. If the fan on the outside unit doesn’t perform correctly, 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 unit not functional
This often indicates a significant reduction of power, contactor problems or even a broken thermostat.
- The coil is frozen
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.
Experts recommend that the most convenient way for a Concord area homeowner to prevent these common 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 efficiently analyze the problem area and apply the necessary repairs. Call or contact us today for an evaluation!
