Condensate drain and overflow repair
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.
- Same-day appointments when available
- Licensed HVAC contractors
- Written price before any repair

In many homes, especially in the South and Southwest, air handlers sit in the attic over living space, so a clogged drain can mean a stained or collapsed ceiling.
A float switch shuts the AC off when water backs up. Many 'AC won't turn on' calls are a tripped float switch.
