Although there may be hundreds of factors why your Champaign home’s central air conditioner may need to be serviced, there are a couple of reasons that are quite common. Recognizing what they are may clarify what a technician is referring to when they discuss the choices for resolving the problem. Here are the top five problems that may result in a system’s failure. Check out the list below and consider whether your home has any of these issues. If so, schedule an HVAC inspection.
- Bad AC wiring
Bad, haphazard or uncertified A/C wiring is risky 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 within your air conditioning system. depleting levels of refrigerant usually will indicate a leak or problem with the refrigerant system. If your air conditioning system needs to be recharged with refrigerant, 90% of the time that suggests 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 encourage you to visit the U.S. EPA website.
- Outside AC fan is not operating
The fan on your air conditioner outside is responsible for conveying the heat from your Champaign home to the outside air. If the fan on the outside unit doesn’t perform correctly, proper heat transfer cannot take 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 often indicates a significant reduction of power, contactor problems or even a faulty thermostat.
- Frozen coil
A frozen coil mainly indicates trouble with the airflow, such as restrictions caused by old air filters or blocked return air ductwork. Frozen indoor coils could also be the result of low refrigerant.
Best practices suggest that the most effective way for a Champaign area homeowner to prevent these common problems is by participating in a preventive maintenance program. Bad wiring, low refrigerant and airflow problems can be found during routine maintenance tune-ups.
