While there may be endless reasons why your Edmonton home’s central air conditioner may need to be looked at by a certified contractor, there are a few reasons that are fairly common. Knowing what they are may create some personal understanding what a technician means when they discuss the choices 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
Bad, haphazard or uncertified A/C wiring is risky and a potential fire hazard. Bad wiring often prevents the system from getting power or can short the circuit breaker.
- Leaking refrigerant
Refrigerant (also known as Freon) is the chemical that cools the air in your air conditioning system. Low refrigerant could imply 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 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 fan is not functioning
The fan on your air conditioner outside is responsible for conveying the heat from your Edmonton 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. The consequence of this action could result in internal damage to the compressor.
- Outside unit not functional
This typically indicates a lack of power, contactor problems or even a bad thermostat.
- Frozen inside coil
A frozen coil typically indicates trouble with the airflow, such as restrictions caused by old air filters or blocked return air ductwork. Frozen indoor coils could also be derived from low refrigerant.
Best practices suggest that the most effective way for a Edmonton area homeowner to prevent these expected 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!
