AC Not Working? Here are some Common AC Problems in Calgary

January 30, 2015

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. Knowing what they are may clarify what a technician means when they address 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.

  1. Bad 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 trip the circuit breaker.

  2. Leaking 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 suggest 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.

  3. Outside fan is not working

    The fan on your outside AC unit is responsible for conveying the heat from your Calgary 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. The consequence of this action could result in internal damage to the compressor.

  4. Outside unit not functional

    This usually indicates a loss of power, contactor problems or even a broken thermostat.

  5. Frozen coil

    A frozen coil mainly indicates trouble with the airflow, such as restrictions caused by dirty air filters or collapsed return air ductwork. Frozen indoor coils could also be caused by low refrigerant.

Experts recommend that the most convenient way for a Calgary area homeowner to prevent these common problems is by participating in a preventive maintenance program. Bad wiring, low refrigerant and airflow problems can be detected during routine maintenance tune-ups.
