Clogged condensate drain lines in older homes
Why it happens here
Heritage summers are humid, so your AC pulls gallons of water out of the air every day. Older drain lines are narrow and often have buildup. Algae and sludge grow fast in the warm condensate. When the line clogs, water backs up into the pan and overflows.
Our approach
We clear the line with a pump and flush it thoroughly. Then we add drain pan tablets to slow future growth. If the line is brittle or collapsed, we replace that section. We also check the pan for cracks and install a float switch if needed.
