Condensate Drain & Overflow Repair in Houston

An AC removes moisture that drains through a small PVC line. Algae and scale clog it, and water backs up into the pan and through the ceiling. A tech clears the line, checks the secondary pan and float switch, and repairs or adds a condensate pump.

Houston

Condensate Drain & Overflow Repair in Houston: what's different

Few cities test condensate drains like Houston. An air handler in a hot attic can produce several gallons of water on a humid afternoon, and algae grows quickly in the PVC line and trap. When the line clogs, the secondary pan fills, the float switch shuts the system down, or water comes through the ceiling of the room below.

Techs in the Houston area often recommend flushing the drain line every spring, adding a cleanout tee if there isn't one, and testing the float switch at each tune-up. Homes with garage or closet air handlers need the same attention, just with less risk to ceilings.

Houston climate

Summers are long, hot and muggy, with high dew points from May through October. Winters are short and mild, though occasional hard freezes stress heat pumps. Hurricanes and tropical storms bring flooding and power outages.
