An Air Conditioner Water Leak Can Turn Into a Bigger Issue — How This Can Happen

air conditioner leakIf you see a puddle of water on the floor underneath your furnace or air conditioner, you’ve most likely got an air conditioner water leak

Air conditioners cool the air and remove humidity during hot, humid summer days. It’s the A/C evaporator coil that does the job of dehumidifying the air, with the cooled air moving through the coil to condense into little drops of water on the surface. The evaporator coil looks a little like a car radiator and is located inside a metal box above your furnace.

When using a full air conditioning system, this beaded water condensation can produce a large volume of water that needs to be drained. Condensed water on the coil drips into a drain pan, which is located just underneath the coil. A drain hose travels from the pan’s drain fitting and down to a floor drain. If something in this process is off, an A/C water leak can develop.

An air conditioner water leak can be coming from a number of places, including:

  • Blockage in the hose or drain pan – If the water’s traveling down the side of your furnace and the inside of the cabinet box is damp, turn the furnace off and check the pan and drain hose.
  • Squashed hose – Search for anything that might be sitting on the drain hose — from storage boxes to laundry. You don’t want to have a technician come all the way out to find that your hose is squashed by those bags of items you’ve been meaning to get rid of.
  • Air lock in drain hose – The discharge end of the hose could be submerged in water with an air bubble causing an air lock.

These are just a few issues that could be causing an air conditioner water leak. For help diagnosing the problem, contact the pros at Rytech.
