AC Not Working? Here are some Common AC Problems in Houston

January 30, 2015

Although there are potentially hundreds of reasons why your Houston home’s central air conditioner may need to be looked at by a certified contractor, there are a few reasons that are quite common. Knowing what they are may help you to understand what a technician means when they address the options 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. Wrong wiring

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

  2. Depleted refrigerant

    Refrigerant (typically referred to as Freon) is the chemical that cools the air within your air conditioning system. depleting levels of refrigerant could indicate a leak or problem with the refrigerant system. If your air conditioning system needs to be recharged with refrigerant, typically that insinuates there is a leak. All refrigerant leaks should be located and repaired. For news about the phase out of R-22 refrigerant in the United States, we encourage you to visit the U.S. EPA website.

  3. Outside fan is not operating

    The fan on your outside AC unit is responsible for transferring the heat from your Houston home to the outside air. If the fan on the outside unit doesn’t run, 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.

  4. Outside unit not functional

    This typically indicates a lack of power, contactor problems or even a bad thermostat.

  5. The coil is frozen

    A frozen coil mainly indicates a problem with the airflow, such as restrictions caused by dirty air filters or collapsed return air ductwork. Frozen indoor coils could also be caused by low refrigerant.

Best practices suggest that the most effective way for a Houston area homeowner to prevent these expected problems is by participating in a preventive maintenance program. Bad wiring, low refrigerant and airflow problems can be detected during routine maintenance tune-ups. For all these common issues, a professionally qualified, NATE-certified technician can efficiently diagnose the problem area and apply the necessary repairs.
