AC Drain Line Clog in Rochester, NH
An AC drain line clog in Rochester, NH shows up as water where it should not be: a stain on the ceiling under an attic air handler, a puddle beside the furnace, or an AC that shuts itself off for no clear reason. Central air pulls gallons of water out of the air on a humid day, and all of it has to leave through a 3/4 inch PVC condensate line.
That line clogs with algae and slime that grows in the dark, damp pipe. Our crew clears it with a wet vac at the outdoor end or with nitrogen pressure from the inside, then flushes it and checks the trap. We also test the float switch or pan sensor that should shut the system down before water overflows. If yours never tripped, we'll find out why.
Attic units need a secondary drain pan under the air handler, and many older installs have a pan that is rusted through. We check it while we're up there.
A clogged drain that tripped the safety switch is a common reason for an AC not turning on. Call (866) 703-1217 when you see water.
