Should Water Ever Leak from an AC System?

There are a few reasons you might be worried when you notice that water is leaking from your AC system. Many homeowners become alarmed, wondering if water should be in the air conditioning system in the first place and whether it will damage the unit. Many worry about water damage and mold growth, and rightfully so.

Water often drips from the backside of a window AC unit, those loud clunky units propped in windows that only cool down a single room (and tend to do a poor job of it). Shoddy manufacturing and poor drainage allow water to move to the outside of your home. However, with a whole-home air conditioning system—designed to drain water to an appropriate drainage system—there should never be leakage in your living space.

About the Condensate Drain System

The condensate drainage system is what is supposed to stop condensate from moving into your home. Condensate forms on the outside of the evaporator coil—located at the indoor air handler of your AC system—as warm, humid air from your home blows past it. The condensation collects beneath the coil in a tray, positioned at an angle so that water flows through a hole at the bottom and into a drainpipe.

How Water Leaks Pop Up

Water leaks into your home when something goes wrong with this system. Common reasons for water leakage include:

  • The condensate drain is clogged with debris, so water backs up.
  • The tray is not in the correct position.
  • The tray is cracked.

When you suspect your AC is leaking, call an expert right away. In addition, we recommend annual AC maintenance visits to stop such problems from happening in the first place.
