Although there may be hundreds of factors why your Rochester home’s central air conditioner may need to be looked at by a certified contractor, there are several reasons that are quite common. Recognizing what they are may create some personal understanding what a technician is saying when they outline the options for fixing the problem. Here are the top 5 list of problems that may cause your AC unit to fail. Review the Top 5 list below and if any of these scenarios exist in your home, please schedule an HVAC inspection.
- Faulty AC wiring
Shotty, haphazard or uncertified A/C wiring is unsafe and a potential fire hazard. Bad wiring can prevent the system from getting power or can short the circuit breaker.
- Your Air Conditioner is Leaking refrigerant
Refrigerant (typically referred to as Freon) is the chemical that cools the air within your air conditioning system. depleting levels of refrigerant could 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 located 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 Rochester home to the outside air. If the fan on the outside unit doesn’t run, 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 broken thermostat.
- Frozen coil
A frozen coil typically 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 caused by low refrigerant.
Best practices suggest that the most effective way for a Rochester area homeowner to prevent these simple problems is by participating in a preventive maintenance program. Bad wiring, low refrigerant and airflow problems can be discovered during routine maintenance tune-ups.
