How To Unclog Your AC Drain Line?

AC Drain Line Maintenance

Clogged condensate drain lines can cause expensive repair that can be avoided. There are ways to prevent water leaks from a clogged AC drain line. Here are the steps to thoroughly clean your AC drain lines.

Step 1: Turn Your AC System Off

Some air conditioning systems will shut off if the condensate line becomes clogged. However, if you notice that the drain line is clogged, turn off your system. If your HVAC system continues to work, it will continue to drain water which can cause your drain pan to overflow causing water damage.

Step 2: Locate Your AC Condensate Drain Line and Runoff

Every HVAC system has a condensate drain line that runs from the indoor air handler to a location outside your home. This drain line removes the water from your AC system as it dehumidifies your home.

In order to unclog your AC drain line, you will need to locate your condensate drain line runoff and have access to it in order to clear them.

You will need to know the location of both your condensate drain line runoff and access to clear the clog.

Step #3: Removing the AC Drain Line Clog

At your drain runoff, attach a wet/dry vac hose to the end of the drain line. You can use a towel or duct tape to make the connection to the drain line more airtight. Run the vacuum a few minutes to blow out any debris or build-up.

You may need to blow air out the drain line, or you may need to use the vacuum as a vacuum to remove the clog. You may need to repeat these steps a few times to completely remove the clog.

For difficult clogs, you may try a mix of bleach/distilled vinegar and hot water to remove build-up. This will help break down the clog and make it easier to remove.

How to Prevent Future AC Drain Line Clogs?

We recommend that you take preventative measures to reduce AC drain line clogs. Pouring a cup of bleach down your condensate line will kill mildew and algae and prevent future growth inside the drain line.
