AC Leaking Water Inside in Gresham

Where the water starts

• Clogged drain line. Algae and dust form a slime that blocks the drain tube.
• Cracked drain pan. Old metal pans rust through, and plastic ones crack with age.
• Failed condensate pump. Systems in basements and crawlspaces often pump water out, and the pump can quit.
• Frozen coil thawing. A big rush of water usually means the coil was iced over.
• Mini-split drain. A kinked or poorly sloped line on a ductless head sends water down the wall.

What to do right now

Turn the system off at the thermostat. Mop up and set a pan or towels under the drip. If water is coming through a ceiling below an attic unit, move furniture out of the way and put a bucket under the wet spot.

Some systems have a safety switch in the drain that shuts the AC off when water backs up. If your AC stopped and you find a full pan, that switch did its job.

Questions about AC Leaking Water in Gresham

Can I clear the drain line myself?

Often. A wet-dry vacuum on the outside end of the drain line can pull out the clog. If the water keeps coming back, have a contractor look at it.

Why does my mini-split drip only on hot days?

It pulls more water out of the air when it runs hard. A drain that barely keeps up on mild days can overflow in a heat wave.
