Although there are potentially hundreds of reasons why your Toronto home’s central air conditioner may need to be repaired, there are a couple of reasons that are quite common. Identifying them may clarify what a technician is saying when they outline the options for correcting the problem. Here are the top five 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.
- Bad 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.
- Your Air Conditioner is Depleting refrigerant
Refrigerant (typically referred to as Freon) is the chemical that cools the air inside your air conditioning system. Low refrigerant may suggest a leak or problem with the refrigerant system. If your air conditioning system needs to be recharged with refrigerant, typically that means there is a leak. All refrigerant leaks should be detected and repaired. To read about the phase out of R-22 refrigerant in the United States, we highly recommend you to visit the U.S. EPA website.
- Outside AC fan is not functioning
The outside fan is responsible for transferring the heat from your Toronto home to the outside air. If the fan on the outside unit doesn’t operate properly, proper heat transfer is not taking place and the air conditioning compressor may overheat and trip the safety overload. This action can lead to internal damage to the compressor.
- Outside air conditioner unit not functional
This typically indicates a significant reduction of power, contactor problems or even a bad thermostat.
- Frozen inside coil
A frozen coil typically indicates a problem with the airflow, such as restrictions caused by dirty air filters or obstructed return air ductwork. Frozen indoor coils could also be the result of low refrigerant.
Experts recommend that the most effective way for a Toronto area homeowner to prevent these simple 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 apply the necessary repairs. Call or contact us today for an evaluation!
