While there may be endless reasons why your Dallas home’s central air conditioner may need to be repaired, there are a few reasons that are quite common. Recognizing what they are may help you to understand what a technician is referring to when they discuss the options for correcting the problem. Here are the top 5 list of problems that may result in a system’s failure. Please review these considerations and determine whether you need to schedule an HVAC inspection.
- Wrong wiring
Improper, haphazard or uncertified A/C wiring is risky and a probable fire hazard. Bad wiring may stop the system from getting power or can trip the circuit breaker.
- Leaking refrigerant
Refrigerant (more commonly referred to as Freon) is the chemical that cools the air within 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 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.
- Outside fan is not functioning
The outside fan is responsible for conveying the heat from your Dallas home to the outside air. If the fan on the outside unit doesn’t operate properly, 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 unit not functional
This usually indicates a lack of power, contactor problems or even a bad thermostat.
- The coil is frozen
A frozen coil typically indicates an issue with the airflow, such as restrictions caused by filthy air filters or collapsed return air ductwork. Frozen indoor coils could also be derived from low refrigerant.
Experts recommend that the most convenient way for a Dallas area homeowner to prevent these expected problems is by participating in a preventive maintenance program. Bad wiring, low refrigerant and airflow problems can be uncovered during routine maintenance tune-ups. For all these common issues, a professionally qualified, NATE-certified technician can efficiently analyze the problem area and make the necessary repairs. Call or contact us today for an evaluation!
