Air Conditioner Condensation Drain Line Cleaning

Learn how to clean your air conditioner condensation drain line.


Hi, I’m Lance with Invitation Homes. And today we’re going to talk about monitoring and cleaning your air conditioner condensation drain line.

A clogged condensation drain line can cause a huge costly mess in your home, but this can be easily avoided by following a few simple steps. First, locate the air conditioning air handler unit inside your home. There are many brands, but it might look something like this. You might find it in a closet, garage, your basement, or even your attic. You’ll notice a drain line, usually a white PVC pipe exiting the unit similar to this one. This line carries the water created by condensation from the AC unit to the outside of your home. If this line becomes clogged, the overflow water will end up draining into your home which could potentially cause damage to your possessions.

Most condensation drain lines have an opening that allows access to the line. Over time this line can become clogged, but you can usually clear the line with a straightened clothes hanger or by vacuuming the line with a wet/dry vacuum. Once the line is clear, you can maintain the open line by pouring a half to a full cup of vinegar in the access opening of the line every six months. If your drain line is clogged and you can’t get it to clear, turn off your air conditioner to prevent water damage. Then call the Invitation Homes maintenance number for your region or enter a maintenance request at
