Why Is My Air Conditioner’s Drain Pan Full of Water?

Picture this: you come home from a long day at work. You’re ready to sit back and relax when you notice that your air conditioner’s drain pan is full of water. Not only is this extremely frustrating, but a hassle to handle. While a drain pan full of water is a sign that there is an issue with your AC, you might be able to do a quick do-it-yourself (DIY) repair.

The Drainpipe is Clogged

When an air conditioner’s drain pan is full of water, the most common culprit is a clogged drainpipe. Inside the refrigerant coils and pipes is a breeding ground for algae, mold, and the like. Overtime, algae and mold can clog the drainpipe and cause water to build up and leak into the drain pan. Although a clogged drainpipe can be an easy fix, it’s important to address the issue right away or else it could cause a mechanical problem.

How to Unclog the Drainpipe

Unclogging the drainpipe is relatively simple. Start by turning off the power supply to your air conditioner. Once the AC is off, inspect the tubing on the unit, making sure there aren’t any leaks, cracks, or other problems with the drain line. If you do find any issue, replace the drain line or faulty pieces. After the pieces have been replaced, remove any water that’s collected in the drain pan (hint: it’s easiest to remove any standing water with a wet-dry vacuum).

Once the water and any residue have been removed, it’s time to unclog. Remove the PVC cap from the drainpipe and clear the clog using a wire brush. It’s also a good idea to add a little bleach into the pipe once the clog is cleared—this will remove any algae or mold that may be contributing to the problem. Replace the PVC cap and proceed to test your air conditioner.
