Flush your AC to Prevent Leaks!

Posted on

Every summer, thousands of homeowners find themselves stuck with air conditioner leaks that seemed to come out of nowhere. It’s only natural – air conditioners have condensers, condensers produce warm water and warm water inevitably leads to mold growth which can clog your condensate pipes, causing leaks. Fortunately, cleaning your AC drain is easy enough to do on your own and only takes a few minutes!

How to Flush your AC

It’s generally a good idea to flush your AC once a year in early spring so you can knock out clogs before they cause big problems. Fortunately, flushing your AC is extremely easy!

To flush your AC , you’ll need:

  • Duct tape or cloth
  • A wet-dry vac
  • Household bleach

The first (and arguably most important) thing to do before you start to flush your AC is shut off your air conditioner before you start working. Flip the air conditioner disconnect switch before you set to work – just to make sure it won’t turn on while you’re working!

Next, find your condensate drain pipe on the outside of your house. This is the pipe that carries water from the condenser coil to the outside so it doesn’t back up into your home. Sometimes, the condensate drain pipe just goes into a sump pump area in your basement. Unfortunately, mold and mildew can build up in the pipes, causing them to back up! If you already have a clog forming (or if you think you do), connect the tube of your wet-dry vac to the pipe and seal it up with duct tape or a piece of tightly wound cloth – or even plastic wrap from your kitchen.  Run the vacuum for a few seconds (shouldn’t take much longer than that). This will dislodge any big clogs that formed over the past year.

Once the clog has been removed, find the access hole of your drain pipe and pour in a cup of regular household bleach. This will kill any mold or mildew stuck in the pipe and prevent it from building up.

That’s all you’ll need! Flushing your AC once a year to clean the condensate drain will help prevent leaks in your air conditioner all summer long. For more air conditioner maintenance tips or to schedule a routine AC tune up in MD or DC, call Michael Bonsby Heating & Air Conditioning today!
