Common Causes of Air Conditioning Failure

Many factors can lead an air conditioning system to malfunction. Some of these include:

  • Accumulated grime and dirt on the AC coil – Over time, grime, dirt and dust can cover your air conditioner’s condenser coil. This can dramatically reduce the system’s ability to cool your home and can lead the system to consume far more energy.
  • Insufficient refrigerant within the system – If the refrigerant level in your air conditioning system is low, it is either the result of a leak, or it having been insufficiently filled at the time of installation. In the case of a leak, our technicians will find the source, repair it, and refill your air conditioning system so that it will once again perform as it should.
  • Clogged AC drain – As the evaporator coils cool warm air, condensation occurs. The accumulated water gets collected in a drip pan and is drained out of the house through a drain line. If that line gets clogged, the water can back up into the system and make your air conditioning system work harder to lower your home’s temperature.
  • Electric control or sensor failures – The air-conditioner’s compressor and fan rely on the proper flow of electrical current. When that flow is disrupted, the AC ceases to function properly. Similarly, your air conditioning system depends on the sensors in your thermostat to tell it went to turn on and off. A malfunctioning thermostat is often the root cause of air conditioning breakdown.
