While there may be endless reasons why your Oakville home’s central air conditioner may need to be repaired, there are a couple of reasons that are most common. Recognizing what they are may create some personal understanding what a technician is referring to when they discuss the choices for correcting the problem. Here are the top 5 list of problems that may result in a system’s failure. Check out the list below and consider whether your home has any of these issues. If so, schedule an HVAC inspection.
- Bad 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 short the circuit breaker.
- Leaking refrigerant
Refrigerant (more commonly referred to as Freon) is the chemical that cools the air in your air conditioning system. Reduced levels of 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 found 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 fan is not functioning
The outside fan is responsible for moving the heat from your Oakville 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.
- Outside unit not functional
This usually indicates a significant reduction of power, contactor problems or even a faulty thermostat.
- Frozen coil
A frozen coil often indicates a problem with the airflow, such as restrictions caused by filthy air filters or blocked return air ductwork. Frozen indoor coils could also be derived from low refrigerant.
Experts recommend that the most effective way for a Oakville area homeowner to prevent these expected problems is by participating in a preventive maintenance program. Bad wiring, low refrigerant and airflow problems can be discovered 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.
