What is Condensate Line?
The condensate line is the drain that carries away the water your AC pulls out of the air at the evaporator coil. When it clogs — typically with algae and dust sludge — the drain pan overflows, either tripping a float switch that shuts the system down or sending water into ceilings and closets.
Why it matters in Arizona
Arizona's twist: the line sits nearly dry all spring (desert air yields little condensate), then monsoon humidity suddenly demands it move real water — and the winter's accumulated dust chokes it on the year's hottest week. A pre-monsoon flow check is the two-minute fix.
