Although there may be hundreds of factors why your Tempe home’s central air conditioner may need to be serviced, there are a few reasons that are most common. Recognizing what they are may create some personal understanding what a technician is saying when they address the routes for correcting the problem. Here are the top five problems that may cause your air conditioning system to break down. Review the Top 5 list below and if any of these scenarios exist in your home, please schedule an HVAC inspection.
- Wrong AC wiring
Shotty, haphazard or uncertified A/C wiring is unsafe and a possible fire hazard. Bad wiring may stop the system from getting power or can short the circuit breaker.
- Your Air Conditioner is Leaking refrigerant
Refrigerant (also known as Freon) is the chemical that cools the air in your air conditioning system. Reduced levels of refrigerant could indicate a leak or problem with the refrigerant system. If your air conditioning system needs to be recharged with refrigerant, usually that suggests there is a leak. All refrigerant leaks should be found and repaired. For news about the phase out of R-22 refrigerant in the United States, we suggest that you to visit the U.S. EPA website.
- Outside AC fan is not turning
The fan on your air conditioner outside is responsible for moving the heat from your Tempe 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. Worse yet, it may cause internal damage to the compressor.
- Outside air conditioner unit not functional
This typically indicates a lack of power, contactor problems or even a faulty 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 number one way for a Tempe 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 promptly diagnose the problem area and implement the necessary repairs.
