Common AC problems in Kitchener Published on January 30, 2015 Although there are potentially hundreds of reasons why your Kitchener home’s central air conditioner may need to be repaired, there are a few reasons that are fairly common. Knowing what they are may clarify what a technician means when they discuss the options for correcting the problem. Here are the top five problems that may result in a system’s failure. Please review these considerations and determine whether you need to schedule an HVAC inspection. Bad wiring Shotty, haphazard or uncertified A/C wiring is dangerous and a possible fire hazard. Bad wiring can prevent the system from getting power or can short the circuit breaker. Low refrigerant Refrigerant (also known as Freon) is the chemical that cools the air within your air conditioning system. Reduced levels of refrigerant could indicate a leak or problem with the refrigerant system. If your air conditioning system needs to be recharged with refrigerant, typically that suggests there is a leak. All refrigerant leaks should be located and repaired. To read about the phase out of R-22 refrigerant in the United States, we suggest that you to visit the U.S. EPA website. Outside fan is not working The outside fan is responsible for conveying the heat from your Kitchener 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. This action can lead to internal damage to the compressor. Outside unit not functional This typically indicates a lack of power, contactor problems or even a faulty thermostat. Frozen coil A frozen coil mainly indicates trouble with the airflow, such as restrictions caused by old air filters or obstructed return air ductwork. Frozen indoor coils could also be caused by low refrigerant. Best practices suggest that the most effective way for a Kitchener 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. For all these common issues, a professionally qualified, NATE-certified technician can efficiently diagnose the problem area and apply the necessary repairs.
