Although there may be hundreds of factors why your North America home’s central air conditioner may need to be looked at by a certified contractor, there are a few reasons that are fairly common. Recognizing what they are may clarify what a technician is referring to when they discuss the routes for resolving the problem. Here are the top 5 list of 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.
- Faulty wiring
Shotty, 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.
- Low refrigerant
Refrigerant (also known as Freon) is the chemical that cools the air within your air conditioning system. Reduced levels of refrigerant could imply a leak or problem with the refrigerant system. If your air conditioning system needs to be recharged with refrigerant, 90% of the time that suggests there is a leak. All refrigerant leaks should be located and repaired. To read about the phase out of R-22 refrigerant in the United States, we highly recommend you to visit the U.S. EPA website.
- Outside fan is not working
The outside fan is responsible for conveying the heat from your North America home to the outside air. If the fan on the outside unit doesn’t perform correctly, 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.
- Outside unit not functional
This usually indicates a lack of power, contactor problems or even a faulty thermostat.
- The coil is frozen
A frozen coil often indicates an issue with the airflow, such as restrictions caused by filthy air filters or obstructed return air ductwork. Frozen indoor coils could also be the result of low refrigerant.
Best practices suggest that the most effective way for a North America area homeowner to prevent these expected 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 promptly analyze the problem area and implement the necessary repairs.
