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 few 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 resolving the problem. Here are the top five 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
Bad, haphazard or uncertified A/C wiring is dangerous and a probable fire hazard. Bad wiring can prevent the system from getting power or can pop the circuit breaker.
- Your Air Conditioner is Low on refrigerant
Refrigerant (also known as Freon) is the chemical that cools the air inside your air conditioning system. depleting levels of refrigerant usually will 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 detected 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 AC fan is not operating
The fan on your outside AC unit is responsible for moving the heat from your Roanoke 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 usually indicates a significant reduction of power, contactor problems or even a bad thermostat.
- Frozen coil
A frozen coil typically indicates a problem with the airflow, such as restrictions caused by filthy air filters or obstructed return air ductwork. Frozen indoor coils could also be caused by low refrigerant.
Best practices suggest that the number one way for a Roanoke 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.
