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

January 30, 2015

Although there are potentially hundreds of reasons why your London home’s central air conditioner may need to be repaired, there are a couple of reasons that are quite common. Recognizing what they are may clarify what a technician means when they address the routes for fixing the problem. Here are the 5 most common problems that may result in a system’s failure. Check out the list below and consider whether your home has any of these issues. If so, schedule an HVAC inspection.

  1. Wrong wiring

    Improper, haphazard or uncertified A/C wiring is risky and a possible fire hazard. Bad wiring can prevent the system from getting power or can pop the circuit breaker.

  2. Low refrigerant

    Refrigerant (typically referred to as Freon) is the chemical that cools the air inside your air conditioning system. depleting levels of refrigerant usually will suggest a leak or problem with the refrigerant system. If your air conditioning system needs to be recharged with refrigerant, typically that means there is a leak. All refrigerant leaks should be found 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 turning

    The fan on your air conditioner outside is responsible for moving the heat from your London 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. Worse yet, it may cause internal damage to the compressor.

  4. Outside unit not functional

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

  5. The coil is frozen

    A frozen coil mainly indicates trouble 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.

Best practices suggest that the most effective way for a London 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.
