While there may be endless reasons why your Denver home’s central air conditioner may need to be looked at by a certified contractor, there are a couple of reasons that are fairly common. Knowing what they are may create some personal understanding what a technician means when they address the options for fixing the problem. Here are the top five problems that may cause your air conditioning system to break down. Please review these considerations and determine whether you need to schedule an HVAC inspection.
- Wrong AC wiring
Bad, 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.
- Your Air Conditioner is Low on refrigerant
Refrigerant (more commonly referred to as Freon) is the chemical that cools the air in your air conditioning system. Low refrigerant usually will indicate 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 located and repaired. To learn about the phase out of R-22 refrigerant in the United States, we suggest that you to visit the U.S. EPA website.
- Outside AC fan is not working
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 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.
- Outside air conditioner unit not functional
This often indicates a lack of power, contactor problems or even a broken thermostat.
- Frozen coil
A frozen coil often indicates a problem with the airflow, such as restrictions caused by dirty air filters or obstructed 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 analyze the problem area and make the necessary repairs. Call or contact us today for an evaluation!
