Although there are potentially hundreds of reasons why your Roanoke home’s central air conditioner may need to be looked at by a certified contractor, there are a couple of reasons that are quite common. Recognizing what they are may help you to understand what a technician is saying when they outline the routes for resolving the problem. Here are the 5 most common 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
Improper, haphazard or uncertified A/C wiring is dangerous and a potential fire hazard. Bad wiring often prevents the system from getting power or can pop the circuit breaker.
- Your Air Conditioner is Leaking refrigerant
Refrigerant (more commonly referred to as Freon) is the chemical that cools the air in your air conditioning system. depleting levels of refrigerant may imply a leak or problem with the refrigerant system. If your air conditioning system needs to be recharged with refrigerant, typically that insinuates there is a leak. All refrigerant leaks should be found 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 AC fan is not operating
The outside fan is responsible for moving the heat from your Roanoke 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 significant reduction of power, contactor problems or even a bad thermostat.
- Frozen coil
A frozen coil typically indicates an issue with the airflow, such as restrictions caused by dirty 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 Roanoke area homeowner to prevent these common problems is by participating in a preventive maintenance program.
