Regular maintenance is required for even the best air conditioners. There are a lot of components to consider, and today we’ll show you how to unclog an air conditioner drain pipe. For a quick rundown: Turn off the AC to be safe. Take off the cap or plug from the opening. Look inside for anything blocking the line. You can use a vacuum or a small brush to remove the clog. If it’s tough, mix vinegar and water or use a special cleaning solution made for AC drains. Pour it in and wait for 30 minutes. Then, flush it with water.

When AC air is not filtered correctly, algae, mold, and bacteria build up in the drainage pipe. Because of this, a clogged AC drain line (also known as an AC condensate drain line) can lead to water stains on the ceiling or even flooding. This excess water can lead to mold growth or, worse yet, a full drain pan that can lead to more problems. Fortunately, a reliable repair service can help prevent water backup and musty odors from developing in the first place. They can inspect and clean your AC condensate drain line to ensure no further issues arise.
Such issues are why catching a clog early on can be the difference between a quick, painless fix and thousands of dollars worth of repairs.

Going through this process won’t always result in an unclogged line. If this is the case, call an HVAC service.
How can I tell if my AC drain line is clogged?
The most noticeable signs of a clogged pipe are lower cooling power, water stains on the ceiling, and an AC unit that drips water or has a moldy smell.
Is bleach or vinegar better for your AC drain line?
Vinegar is a better option because it’s as effective as bleach and has lower health risks.
How often should you put vinegar in your air conditioner?
Putting a cup of vinegar in your drainpipe should be done every month for best results.
STAT: Experts say that, if your lights only lose about 5% of their brightness, this isn’t a sign that someone is wrong with your AC unit. (source)
