Although there are potentially hundreds of reasons why your Richmond home’s central air conditioner may need to be serviced, there are several reasons that are fairly common. Knowing what they are may create some personal understanding what a technician means when they discuss the routes for fixing the problem. Here are the top five 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
Improper, haphazard or uncertified A/C wiring is risky and a probable fire hazard. Bad wiring may stop the system from getting power or can short the circuit breaker.
- Leaking refrigerant
Refrigerant (more commonly referred to as Freon) is the chemical that cools the air within your air conditioning system. Reduced levels of refrigerant could suggest 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 detected and repaired. To learn 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 turning
The outside fan is responsible for transferring the heat from your Richmond home to the outside air. If the fan on the outside unit doesn’t run, proper heat transfer cannot take 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 typically indicates a loss of power, contactor problems or even a broken thermostat.
- Frozen coil
A frozen coil often indicates an issue with the airflow, such as restrictions caused by old air filters or obstructed return air ductwork. Frozen indoor coils could also be derived from low refrigerant.
Experts recommend that the most effective way for a Richmond area homeowner to prevent these simple 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 analyze the problem area and apply the necessary repairs. Call or contact us today for an evaluation!
