what causes a leaky furnace? | |
The furnace is in the attic above the bathroom. Apparently it was leaking last night because the bathroom floor is wet and the rug drenched. Only knowing that the leak came from some where in the attic, I climbed up there a few minutes ago and found the pan under the furnance had a little water. The pvc pipe right above the pan had condensation. I couldn't find any more water. Any ideas?
Answers:
1Your air conditioner air handler is in the attic and should have a primary condensate (water) drain as well as an emergency overflow pan drain. You apparently noticed that the emergency overflow pan under the air handler unit had some condensate water in it. This indicates that your primary condensate water drain is clogged up. There should be a U shaped trap in the primary drain line attached to the air handler. The U shaped trap needs to be taken apart and cleaned out so that the water can drain freely out through the trap to your household plumbing drain line connection. The emergency drain pan under the air handler is usually connected to another drain line that may go across your attic floor to drain directly outside your house somewhere. You may have to turn your A/C off until the primary condensate water drain line is unclogged if that's where your water leak came from.
