AC Not Working? Here are some Common AC Problems in Kitchener

January 30, 2015

While there may be endless reasons why your Kitchener home’s central air conditioner may need to be looked at by a certified contractor, there are a couple of reasons that are most common. Identifying them may create some personal understanding what a technician is saying when they outline the options for correcting the problem. Here are the top 5 list of problems that may cause your air conditioning system to break down. Check out the list below and consider whether your home has any of these issues. If so, schedule an HVAC inspection.

  1. Bad wiring

    Incorrect, haphazard or uncertified A/C wiring is risky and a possible fire hazard. Bad wiring can prevent the system from getting power or can trip the circuit breaker.

  2. Depleted refrigerant

    Refrigerant (also known as Freon) is the chemical that cools the air in 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, usually that suggests there is a leak. All refrigerant leaks should be detected and repaired. For news about the phase out of R-22 refrigerant in the United States, we highly recommend you to visit the U.S. EPA website.

  3. Outside fan is not operating

    The outside fan is responsible for transferring the heat from your Kitchener 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. Worse yet, it may cause internal damage to the compressor.

  4. Outside unit not functional

    This typically indicates a lack of power, contactor problems or even a faulty thermostat.

  5. Frozen coil

    A frozen coil often indicates an issue with the airflow, such as restrictions caused by old air filters or obstructed return air ductwork. Frozen indoor coils could also be derived from low refrigerant.

Best practices suggest that the most convenient way for a Kitchener area homeowner to prevent these simple 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 quickly diagnose the problem area and implement the necessary repairs.
