Yes.
As homeowners and renters prepare for the scorching Florida summer, pouring hot water down the AC drain line can help alleviate minor clogs. The drain line is a white PVC pipe on the AC handler, usually found in a closet or garage.
If the drain line is clogged, the AC may shut down or leak. First, turn off the AC unit. Locate the drain line and take off the cap. Slowly pour about a half a gallon of hot water (not boiling) down it and replace the cap. The water will dissolve buildup in the line.
Some experts recommend pouring a small amount of vinegar before the hot water, but others say it isn’t good for the system’s long-term health. Consult a professional before using this method.
You can also use a shop vacuum to clear clogs if you locate where your drain line leads to outside.
