Water is pooling around your inside unit and you’re a bit worried.
Water leaking out of and pooling around your inside air conditioning unit isn’t normal. There’s a problem that you or a professional need to fix.
Before explaining why this is happening, turn off your AC to protect its electrical components from harm.
OK, now that we’ve gotten that out of the way, let’s explain:
Before we get to how the AC leaks out, we need to explain how it gets there in the first place.
The inside AC unit has a frigidly cold evaporator coil that cools the air flowing over it. When air hits the coil, the air’s moisture condenses on the coil.
It’s just like how water droplets condense on an ice cold glass of sweet tea during a scorching Atlanta summer.
As water forms, it falls into a drain pan and out a condensate drain line. You should see the drain line exit point as a PVC pipe near your outside AC unit.
OK, so now you know how the water got there. Now let’s talk about why it’s leaking into your home.
There are many possible issues that can cause water to leak into your home.
Here are the usual suspects:
The drain line can get clogged with dirt, insects, mold and other sludge. The clog causes the water to back up and into your home.
While this may unclog the drain, dirt from the evaporator coil may clog the drain again soon.
You’ll know this is the problem if your AC has a hard time cooling your home.
The evaporator coil may be freezing up (literally). So when the ice melts, water flows over the drain pan and leaks on to your floor.
Regardless of the cause, fix this problem ASAP to prevent serious damage to your AC.
Simple as it sounds: over time the drain line can get disconnected, allowing water to spill into your home.
To move the water from the pan to a drain, some air conditioners need a condensate pump. If the pump is busted, the water won’t drain out and can overflow into your home.
An old drain pan can rust through and crack, so water leaks onto the floor instead of down the drain.
