DIY Guide To Unclogging Your Drain Line?

Several modern HVAC systems feature sensors that will notify you if your AC drain line gets clogged, allowing you to address the issue before water damage is caused. If your unit doesn’t have this feature, the drain pan will be full of water, indicating that the AC drain line is clogged. Before calling an AC company in Wilmington, DE, to help you unclog the drain, you can also try to unclog it by yourself. Continue reading to know-how!

Why Is My Air Conditioner Drain Line Clogged?

The AC condensate drain line eliminates the water produced when the evaporator in your air conditioner transforms the refrigerant from a liquid to a gas. As a result, algae and other dirt may add up over time. If you don’t clean your AC regularly, this might result in an AC drain line being clogged up. Need air conditioner repair Wilmington, DE. Contact D&T Heating and Cooling for best services.

Fortunately, unclogging the AC drain line is simple and can be done using items you most likely already have in your cleaning supplies. Here’s how to unclog your AC drain lines in an hour:

Materials Required

  1. Rubber gloves
  2. A thin and stiff wire brush
  3. Duct tape
  4. A wet or dry vacuum
  5. Bleach


  1. Before cleaning your Air conditioner, ensure it is turned off.
  2. Locate the drain line of your air conditioner. The majority of AC drain pipes are found outdoors, close to the condenser unit.
  3. Insert the stiff, thin brush in the drain line’s bottom. This may help to eliminate any clogs towards the drain line’s bottom. The AC drain line blockage will most probably appear further down, and you’ll have to take a bit more effort.
  4. Connect the other end of your wet or dry vacuum to the AC drain line. Duct tape is used to fasten it. Turn on the vacuum to eliminate any debris and, possibly, remove the clog.
  5. Retrieve the wet/dry vac and return indoors after roughly a minute of vacuuming. If the drain pan is clogged, vacuum this out and scrub it clean with soap.
  6. Find the vent tee. This is a pipe fitting that links the drain line from your air conditioner to the drainage tray. Disconnect the vent tee’s PVC cap.
  7. Use the stiff, thin wire brush to clear up any clogs in the AC drain pipe that are easy to reach.
  8. Wear your gloves and pour a one-cup bleach-to-one-cup-water solution down the drain pipe’s top. (When dealing with bleach, observe all safety precautions.) Wait thirty minutes before proceeding.
  9. Get a helper to stand out and keep an eye on the AC drain line to check if any water is draining. Working on your own? To test whether the AC drain line clog has been removed, position a bucket at the end of the drain line.
  10. Fill the vent tee with water and check to see whether it went all the way through the AC drain line. And you’re done!
