How To Clear A Backed Up Air Conditioner Drain Line.

If you live in the Brevard County, Florida area, including Melbourne, Palm Bay, and Viera, and you are experiencing issues with your air conditioning system, it may be due to a clogged or backed-up condensate drain line. A clogged drain line can cause your air conditioner to stop working properly and can even lead to water damage in your home if left unaddressed.

Fortunately, cleaning and flushing out the condensate drain line is a relatively easy task that you can do yourself, but if you are not comfortable tackling the job, you can always contact a professional HVAC company like Quality Comfort Air Conditioning and Heating Inc. to take care of it for you.

Here are the steps you can take to flush and clean your condensate drain line:

  1. Locate the drain line: The condensate drain line is typically located near the outdoor condenser unit of your air conditioning system. It will be a small white PVC pipe.
  2. Turn off the power: Before you begin working on your air conditioning system, make sure to turn off the power to the unit to avoid any accidents.
  3. Vacuum the drain line from the outside: Using a wet/dry vacuum, suck out any debris or clogs from the end of the drain line that is located outside usually near the condenser unit. This will help to remove any large blockages that may be causing the backup.
  4. Locate the clean-out: Once you have vacuumed the drain line from the outside, locate the clean-out. This is usually a PVC t-fitting that has a cap on the top that is located usually within a few inches of the air handler.
  5. Remove the clean-out cap:
  6. Flush the drain line: Once the clean-out cap is removed, you can use a gallon of water and about a cup of bleach. Pour the water slowly into the drain line for a few minutes to flush out any remaining debris or clogs that may be causing the backup then pour in the bleach very slowly to avoid splashing on you then chase the cup of bleach with the remaining water.
  7. Replace the clean-out cap: Once the drain line has been thoroughly flushed, replace the clean-out cap securely.
  8. Test the drain line: Turn the power back on to your air conditioning system and let it run for a few minutes to ensure that the drain line is functioning properly. If water is flowing freely through the drain line, the job is complete. If the drain line is still clogged or backed up, you may need to use a more heavy-duty method to clear the blockage.
