The Five Most Common Air Conditioning Problems Toronto Homeowners Face

January 30, 2015

While there may be endless reasons why your Toronto home’s central air conditioner may need to be repaired, there are a couple of reasons that are most common. Knowing what they are may clarify what a technician is saying when they outline the routes for fixing the problem. Here are the 5 most common problems that may cause your AC unit to fail. Check out the list below and consider whether your home has any of these issues. If so, schedule an HVAC inspection.

  1. Faulty AC wiring

    Incorrect, haphazard or uncertified A/C wiring is unsafe and a potential fire hazard. Bad wiring often prevents the system from getting power or can pop the circuit breaker.

  2. Your Air Conditioner is Depleting refrigerant

    Refrigerant (typically referred to as Freon) is the chemical that cools the air inside your air conditioning system. Reduced levels of refrigerant usually will indicate a leak or problem with the refrigerant system. If your air conditioning system needs to be recharged with refrigerant, usually that insinuates there is a leak. All refrigerant leaks should be found and repaired.

  3. Outside AC fan is not functioning

    The fan on your outside AC unit is responsible for conveying the heat from your Toronto home to the outside air. If the fan on the outside unit doesn’t operate properly, proper heat transfer cannot take place and the air conditioning compressor may overheat and trip the safety overload. This action can lead to internal damage to the compressor.

  4. Outside air conditioner unit not functional

    This usually indicates a significant reduction of power, contactor problems or even a bad thermostat.

  5. Frozen inside coil

    A frozen coil typically indicates an issue with the airflow, such as restrictions caused by filthy air filters or blocked return air ductwork. Frozen indoor coils could also be caused by low refrigerant.

Experts recommend that the most effective way for a Toronto area homeowner to prevent these common problems is by participating in a preventive maintenance program. Bad wiring, low refrigerant and airflow problems can be uncovered during routine maintenance tune-ups. For all these common issues, a professionally qualified, NATE-certified technician can promptly diagnose the problem area and make the necessary repairs. Call or contact us today for an evaluation!
