Water around the furnace or AC?

Water near the furnace almost always comes from the air conditioner or a high-efficiency furnace’s condensate line. Both are fixable, and both get expensive if they reach the drywall.

Questions

Water Leaking From Furnace or AC, answered.

Can a leaking AC damage my furnace?

Yes. The AC coil sits on top of the furnace, so overflow drips into the furnace cabinet and rusts the parts that matter. Fix it early.
