Although there may be hundreds of factors why your Calgary home’s central air conditioner may need to be looked at by a certified contractor, there are several reasons that are fairly common. Identifying them may clarify what a technician is referring to when they outline the routes for resolving the problem. Here are the 5 most common problems that may cause your AC unit to fail. Please review these considerations and determine whether you need to schedule an HVAC inspection.
- Bad AC wiring
Shotty, haphazard or uncertified A/C wiring is unsafe and a possible fire hazard. Bad wiring often prevents the system from getting power or can short the circuit breaker.
- Your Air Conditioner is Low on refrigerant
Refrigerant (more commonly 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 found 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 working
The outside fan is responsible for conveying the heat from your Calgary 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. Worse yet, it may cause internal damage to the compressor.
- Outside air conditioner unit not functional
This usually indicates a lack of power, contactor problems or even a broken thermostat.
- Frozen coil
A frozen coil mainly indicates trouble with the airflow, such as restrictions caused by filthy air filters or collapsed return air ductwork. Frozen indoor coils could also be the result of low refrigerant.
