AC Not Working? Here are some Common AC Problems in San Antonio

January 30, 2015

Although there are potentially hundreds of reasons why your San Antonio home’s central air conditioner may need to be serviced, there are several reasons that are fairly common. Recognizing what they are may help you to understand what a technician means when they discuss the routes for resolving the problem. Here are the 5 most common 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.

  1. Bad wiring

    Shotty, haphazard or uncertified A/C wiring is risky and a probable fire hazard. Bad wiring often prevents the system from getting power or can trip the circuit breaker.

  2. Low refrigerant

    Refrigerant (also known as Freon) is the chemical that cools the air within your air conditioning system. Reduced levels of refrigerant may imply 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 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.

  3. Outside fan is not functioning

    The fan on your outside AC unit is responsible for transferring the heat from your San Antonio home to the outside air. If the fan on the outside unit doesn’t operate properly, proper heat transfer cannot take place 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.

  4. Outside unit not functional

    This typically indicates a significant reduction of power, contactor problems or even a faulty thermostat.

  5. Frozen coil

    A frozen coil often indicates an issue with the airflow, such as restrictions caused by filthy air filters or blocked 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 simple 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 efficiently analyze the problem area and implement the necessary repairs.
