AC Leaking Water

Professional AC Leaking Water in Asheville & Western NC

An air conditioner leaking water inside your home needs prompt attention. Mold growth can begin in as little as 24-48 hours, and prolonged moisture will damage drywall, flooring, and ceiling materials.

What Causes an AC to Leak Water

During normal operation, your AC pulls moisture out of the air as a byproduct of the cooling process. That condensation collects in a drain pan beneath the evaporator coil and exits through a condensate line to the exterior. When something interrupts this drainage path, water backs up and overflows indoors. The leading culprit is algae and biofilm clogging the condensate drain line. Other causes include a corroded or cracked drain pan, a frozen evaporator coil producing excess water as it thaws, a disconnected or misaligned drain line, or a condensate pump that has stopped working.

Quick Things You Can Check

Find the condensate drain line — typically a PVC pipe that runs from your air handler to an exterior wall. If water isn't dripping from the outlet while the system runs, the line is likely blocked. Shut the system off immediately to stop water accumulation. Inspect the air filter — a heavily restricted filter can cause coil icing, which produces a surge of water during thaw cycles. Use towels or a wet-vac to contain standing water.

When This Becomes a Serious Problem

Drywall and flooring repairs from water damage add up fast, and professional mold remediation is even more costly. When a frozen coil is behind the leak rather than a simple drain clog, the root cause — whether low refrigerant or airflow restriction — will keep producing leaks until it is addressed. If cooling performance has also dropped or your AC is not cooling at all, the issues are likely connected.
