Cooling - Condensate Leak

Cooling

Re: Condensate Leakage

The air conditioning condensate is leaking from the a/c coil instead of running out the drain.

CHECKOUT:

1. Identify the Source of Water

• Try to identify where the water is coming from.
  • Is the water coming from the coil, from sweating ductwork or lines, or from leaking pipe joints, etc.

2. Check the Indoor Coil

• Check the indoor coil to make sure that it is not frozen.
  • Even without ice on the lines, the coil can be partially frozen.
    • Frozen Coil --> Turn the A/C "Off" and allow the indoor fan to stay running until coil completely thaws.
      • Be prepared for large amounts of water as the coil thaws.

3. Inspect the Drain Line

• Inspect the drain line and make sure that it is properly installed & properly sloped.
  • On a heat pump system with the drain on the "return-side" of the blower, make sure that the drain is trapped before any open air vents.

4. Check the Drain Pan

• Remove access panel to indoor coil.
• Inspect drain pan for standing water.
  • Standing water in the drain pan above the drain outlet = Clogged Drain or Double-Trapped Drain
  • Empty Drain Pan --> Pour water into the drain pan and make sure that it exits through the drain line.
    • Water leaks from drain pan (doesn't overflow) = Hole in the Drain Pan

5. Examine the Coil in Operation

• If possible, observe the coil and drain while the system is operating.
• Look for water that is blowing off of the coil and missing the drain pan.
