An air conditioner that’s leaking water can cause a substantial amount of damage in a home before the problem is discovered. It can damage floors, walls and carpets, as well as fixtures, furniture and home belongings.

The good news is that in most cases, proper maintenance and operation of a central A/C system not only will prevent water leaks but extend air conditioner life span, too.

Why Is the A/C Producing Water?

A properly functioning central A/C system both cools and dehumidifies. As a fan blows air across the evaporator coil, refrigerant that’s converting from a liquid into a gas removes both heat energy and moisture from the air.

When the system is operating as intended, the condensed moisture drips from the coil into a condensate collection pan underneath, then flows through a drain line into the household sewage drain. Problems arise when something blocks that process, forcing the water to back up and flood.

Common Causes of an A/C Water Leak

Poor installation. If the system hasn’t been installed in a level position, or connections in the drain system aren’t tight, the A/C might leak water. You can avoid this by scheduling professional installation from a trusted HVAC contractor in the first place.

Drain line is blocked. Because of the moisture inherent in the drainage system, algae can form and eventually block the drain line, allowing water to back up and flood. Routine preventative maintenance on your A/C should keep this from happening.
