A Florida Plumber Explains How to Clean Your AC Drain Line With Vinegar

How to Clean Your AC Drain Line With Vinegar

Have you ever used vinegar to clean your AC’s condensate drain line? Your air conditioner cools your home, but it also dehumidifies the air. You might wonder, where does all that extra moisture go?

Your air conditioning system and parts of your plumbing systems have condensate drain lines that remove excess moisture. When it’s working properly, the condensate drain will channel fluid from the air inside your home to the outside where it belongs. Sometimes, the condensate drain gets dirty and needs cleaning.

Luckily, cleaning the condensate drain is easy and all you need is something you probably already have: vinegar.

How to Tell If Your AC Drain Line is Clogged

Whenever your air conditioning system runs, water should drip from the condensate drain. To check for any issues with your condensate drain, you first need to find it. The condensate drain is the white, plastic PVC pipe located outside your home near the compressor. Once you find the condensate drain, if no water is dripping from it, the drain might be clogged.

If you see that your condensate line is clogged, you must immediately clean away the blockage. A backed-up condensate drain is a perfect spot for bacteria and algae to grow, which can result in the drain pan spilling over and causing water damage inside your home. It’s important to regularly check and clean the condensate pan and drain line before a more serious issue happens.

How to Clean an AC Drain Line Using Vinegar in 5 Steps

Even if your condensate line is blocked, fixing the problem is easy. All you need are a few extra minutes, a little elbow grease and some distilled vinegar.


  • ¼ Cup Distilled Vinegar


Step 1. Locate the drain line (look for a PVC pipe).

Step 2. Remove the drain line plug (the cover of the drain line).

Step 3. Pour in a ¼ cup of distilled vinegar. The acidity in vinegar kills algae and bacteria, but keep in mind that it may take a few hours to remove the clog if it is severe.

Step 4. Repeat the process until the drain is clear.

Step 5. Check and clean your drain lines once a month to keep your condensate line free of algae buildup.
