Although there are potentially hundreds of reasons why your Winnipeg home’s central air conditioner may need to be repaired, there are a few reasons that are fairly common. Identifying them may help you to understand what a technician is saying when they discuss the choices for resolving the problem. Here are the 5 most common problems that may result in a system’s failure. Please review these considerations and determine whether you need to schedule an HVAC inspection.
- Faulty AC wiring
Incorrect, haphazard or uncertified A/C wiring is unsafe and a probable fire hazard. Bad wiring may stop the system from getting power or can short the circuit breaker.
- Your Air Conditioner is Low on refrigerant
Refrigerant (also known as Freon) is the chemical that cools the air in 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 means there is a leak. All refrigerant leaks should be located and repaired. To learn 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 functioning
The fan on your air conditioner outside is responsible for transferring the heat from your Winnipeg 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. This action can lead to internal damage to the compressor.
- Outside air conditioner unit not functional
This usually indicates a lack of power, contactor problems or even a bad thermostat.
- The coil is frozen
A frozen coil mainly indicates a problem with the airflow, such as restrictions caused by old air filters or collapsed return air ductwork. Frozen indoor coils could also be the result of low refrigerant.
Best practices suggest that the most convenient way for a Winnipeg area homeowner to prevent these expected 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 efficiently diagnose the problem area and apply the necessary repairs.
