What to Do When Your A/C Condensation Line is Clogged

by | Dec 30, 2021

Thank goodness for air conditioners! Not only do they keep us comfortable all summer long, they also remove humidity from your home. This moisture flows into a drain tube that leads outside your home. Sometimes this tube (aka the condensation line) can become clogged and lead to water damage. So, what now?

What Causes a Clogged Condensation Line?

The drain line is a prime location for mold, mildew, and sludge. Dirt, debris, and even bugs can find their way into the line! All of these things could cause a clog and if not removed immediately, water will begin to back up.

Signs of a Clogged Condensation Line

Many modern air handlers can detect when the drip pan is too full and will shut off. More sophisticated models can even send a text message or email when this happens. If your system does not have this feature, there are several signs of a clogged condensation line. Here are a few of the most common signs …

  • Air conditioner is dripping water
  • Air conditioner is not cooling your house
  • Higher energy bills
  • Air conditioner won’t turn on

How to Clear Up a Drain Line Clog

Cleaning out a drain line isn’t a DIY job for every homeowner, but here are some tips if you want to give it a try.

  1. Turn off your air conditioner.
  2. Find the drain pipe. It is located outside if you live in a single family home, inside with the furnace if you live in a shared building. 
  3. The drain line is a PVC pipe with a plastic cap. Remove the cap.
  4. Visually inspect the drain line with a flashlight to check for debris.
  5. Remove any visible debris.
  6. Pour one cup of distilled white vinegar into the pipe.
  7. Replace the drain cap. 
  8. Wait one hour and then turn your air conditioner back on.
