Although there are potentially hundreds of reasons why your Wheeling home’s central air conditioner may need to be looked at by a certified contractor, there are a few reasons that are fairly common. Knowing what they are may help you to understand what a technician is saying when they discuss the options 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.
- Faulty wiring
Improper, haphazard or uncertified A/C wiring is risky and a possible fire hazard. Bad wiring can prevent the system from getting power or can short the circuit breaker.
- Depleted refrigerant
Refrigerant (typically referred to as Freon) is the chemical that cools the air in your air conditioning system. Reduced levels of refrigerant may indicate a leak or problem with the refrigerant system. If your air conditioning system needs to be recharged with refrigerant, typically that suggests 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 suggest that you to visit the U.S. EPA website.
- Outside fan is not functioning
The outside fan is responsible for transferring the heat from your Wheeling home to the outside air. If the fan on the outside unit doesn’t run, 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 unit not functional
This usually indicates a loss of power, contactor problems or even a faulty thermostat.
- Frozen coil
A frozen coil often indicates a problem with the airflow, such as restrictions caused by dirty air filters or obstructed return air ductwork. Frozen indoor coils could also be derived from low refrigerant.
Best practices suggest that the most convenient way for a Wheeling 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 quickly review the problem area and make the necessary repairs. Call or contact us today for an evaluation!
