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

January 30, 2015

Although there are potentially hundreds of reasons why your Hillsborough 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 help you to understand what a technician means when they outline the routes for correcting the problem. Here are the top 5 list of 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.

  1. Faulty 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. Leaking refrigerant

    Refrigerant (also known as Freon) is the chemical that cools the air inside your air conditioning system. Reduced levels of refrigerant could suggest a leak or problem with the refrigerant system. If your air conditioning system needs to be recharged with refrigerant, typically that insinuates there is a leak. All refrigerant leaks should be found 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.

  3. Outside fan is not working

    The outside fan is responsible for conveying the heat from your Hillsborough home to the outside air. If the fan on the outside unit doesn’t run, proper heat transfer does not occur and the air conditioning compressor may overheat and trip the safety overload. This action can lead to internal damage to the compressor.

  4. Outside unit not functional

    This typically indicates a significant reduction of power, contactor problems or even a bad thermostat.

  5. Frozen inside coil

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

Best practices suggest that the number one way for a Hillsborough area homeowner to prevent these expected 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 quickly analyze the problem area and apply the necessary repairs. Call or contact us today for an evaluation!
