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

January 30, 2015

Although there are potentially hundreds of reasons why your Denver home’s central air conditioner may need to be looked at by a certified contractor, there are a few reasons that are fairly common. Identifying them may help you to understand what a technician means when they address the options for fixing the problem. Here are the top five problems that may result in a system’s failure. Review the Top 5 list below and if any of these scenarios exist in your home, please schedule an HVAC inspection.

  1. Wrong wiring

    Improper, haphazard or uncertified A/C wiring is unsafe and a possible fire hazard. Bad wiring often prevents the system from getting power or can short the circuit breaker.

  2. Leaking refrigerant

    Refrigerant (more commonly referred to 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, typically that suggests there is a leak. All refrigerant leaks should be located and repaired. For news about the phase out of R-22 refrigerant in the United States, we suggest that you to visit the U.S. EPA website.

  3. Outside fan is not operating

    The fan on your air conditioner outside is responsible for moving the heat from your Denver home to the outside air. If the fan on the outside unit doesn’t perform correctly, 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 often indicates a lack of power, contactor problems or even a faulty thermostat.

  5. 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 the result of low refrigerant.

Best practices suggest that the most convenient way for a Denver area homeowner to prevent these expected problems is by participating in a preventive maintenance program. Bad wiring, low refrigerant and airflow problems can be found during routine maintenance tune-ups. For all these common issues, a professionally qualified, NATE-certified technician can quickly diagnose the problem area and apply the necessary repairs. Call or contact us today for an evaluation!
