Causes of a Leaking Air Conditioning System

If you listen to your air conditioner operate, you may hear the occasional drip of liquid inside the cabinet. This is a normal part of the AC’s cooling cycle, and you shouldn’t see any water actually drip out of the cabinet…

…most of the time.

Air conditioner leaking does sometimes occur, and should you spot liquid coming from your AC, or stains around the cabinet or anything near it, call for professional repair technicians right away. A number of causes could lay behind this problem, and the experts will be able to determine what’s wrong and how to fix it.

For the necessary skilled technicians to repair your air conditioning in Pomona, NY when leaks happen, call on Design Air Inc. We won’t leave your AC until you are 100% satisfied with our repair work.

Reasons for a leaking AC

First, you should know that liquid leaking from your AC could be either water or the refrigerant that runs through the system. You don’t want either to leak, although they have different effects.

  • Clogged condensate drain: This is the most common cause for leaking. The water that condenses along the evaporator coil of the inside unit drips down into a shallow condensate pan, and then out a drain line. The drain can develop clogs during the summer from mold growth, and when this happens the pan will quickly overflow and leak water. This can damage your walls, carpets, and furnishings. If the AC sits over your furnace, the water will can cause the furnace to start to rust. A repair technician can remove the condensate pan and clear or replace the drain to stop the overflow.
  • Broken condensate pump: This is the pump that removes water from the condensate pan. If it breaks, the water will not drain properly, and as in the example above, the pan will overflow.
  • Air leaks: Air can get inside the cabinet if the seals around the cabinet are loose. This will cause excess moisture inside the AC as the warmer outside air collides with the cooled air. Repair technicians will need to seal the unit.
  • Formicary corrosion: You may think of the refrigerant line in your AC as corrosion-proof, but it isn’t. A specific type of corrosion, formicary corrosion, that develops from household chemicals and building material can weaken the refrigerant line and cause it to leak. Leaking refrigerant will harm the cooling ability of the AC and damage the compressor.

Whatever the cause of the leak, it will likely grow worse if you do not take steps to remedy it. The first step is the easiest: call Design Air Inc and talk to one of our AC repair specialists. We have 24-hour emergency service, so don’t wait when you discover that leak… call us now.
