While there may be endless reasons why your San Antonio 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. Recognizing what they are may clarify what a technician is referring to when they discuss the choices for resolving the problem. Here are the top 5 list of problems that may cause your air conditioning system to break down. Review the Top 5 list below and if any of these scenarios exist in your home, please schedule an HVAC inspection.
- Faulty wiring
Bad, haphazard or uncertified A/C wiring is risky and a possible fire hazard. Bad wiring may stop 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. Low refrigerant may suggest a leak or problem with the refrigerant system. If your air conditioning system needs to be recharged with refrigerant, usually that insinuates there is a leak. All refrigerant leaks should be detected 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.
- Outside fan is not working
The outside fan is responsible for moving the heat from your San Antonio 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. The consequence of this action could result in internal damage to the compressor.
- Outside unit not functional
This usually indicates a lack of power, contactor problems or even a broken thermostat.
- Frozen coil
A frozen coil often indicates an issue with the airflow, such as restrictions caused by old air filters or collapsed return air ductwork. Frozen indoor coils could also be derived from low refrigerant.
Experts recommend that the most effective way for a San Antonio area homeowner to prevent these common problems is by participating in a preventive maintenance program. Bad wiring, low refrigerant and airflow problems can be discovered during routine maintenance tune-ups.
