Common Causes of a Leaking AC Unit


Prevent water damage, mold and mildew growth, and more by learning about these common AC unit leaks.

Clogged Condensate Drain Line If your drain pan is clear, there may be a clog in the drain line, which is made of PVC pipe, causing water to back up. Flushing the condensate pipe can usually resolve the clog. Additionally, a cracked pipe can also leak water, which may be the source of the issue.

A Clogged Drain Pan AC drain pans can become damaged over time, especially if the unit is reaching the end of its lifespan. The pan may have become corroded and rusted all the way through, causing water to pool underneath. Simply replacing the drain pan may solve the problem.

Low Refrigerant An AC unit without enough refrigerant can leave the system unable to cool effectively. This can cause the coils to freeze, which will overflow the pan after it thaws out.

Disconnected Drain Line Improperly installed equipment or a pipe that has become loosened over time may be the cause of a leaking AC unit. This can cause water spots to form on the ceiling, or a larger leak can cause an entire ceiling to collapse.

Condensate Pump Issues The condensate pump collects and stores the water produced by your HVAC system and transfers it to a drain line. If the pump is not functioning properly, water can leak into your home instead of out.
