Step 1. Turn off your air conditioner. Turn the system off at the thermostat as well as at the breaker. Step 2. Locate your condensate drain line. Your drain line is a PVC pipe located near your outdoor unit and is attached to the wall of your house. Step 3. Identify the access point on the drain line. Most drain lines will have a T-shaped vent tee with a cover or cap. Remove the cap at the top of the drain and inspect for blockage. Step 4. Flush with distilled vinegar. Add ¼ cup of distilled vinegar to the drain line through the opening where the cap was removed. It’s recommended you use regular distilled white vinegar, as the increased acidity boosts its cleaning properties. If you find the smell of vinegar foul, you can also use peroxide or hot water and a dash of dish soap. Step 5. Let the solution sit for 30 minutes. Flush the pipe out with water to ensure everything is flowing freely and operating as it should. Step 6. Repeat each month. Kill any harmful bacteria or buildup and make sure your system continues to operate at peak performance by cleaning your drain line every 30 days (probably way to often - DRW). LIQUID DISHWASHER SOAP ALSO WORKS FINE. NOTE - IN MY CASE, I add a little liquid dishwasher soap to the drip pan IN MY HOUSE - It sits under the drip pan where the air is blown by cooling tubes/radiator to cool off the air . This causes moisture to collect in the drip pan - the water flows out UNLESS the drain tube is blocked by mold/algae/mildew, in which cause the water will overflow the pan and make things nearby wet (which happened to me, once).
