One of the most common air conditioner complaints is that moisture is dripping out of the AC vents. This can be messy and inconvenient during hot weather, but it is not usually an indication of catastrophic problems with your air conditioning system. Below are some of the reasons your AC vents could be leaking and what to do about it.

Condensation on Ducts

When warm, moist air touches a cool surface, the damp air quickly cools and gives up its moisture. If your uninsulated ducts travel through a warm space in the home such as an attic or garage, the warm, damp air could be condensing on the cool metal of the duct, and this water could be dripping through the vents. Ask your HVAC contractor about insulating your ducts to solve this issue.

Clogged Condensate Line

Condensation also forms within the AC unit when warm air touches the cold metal of the evaporator coils. This moisture is normally channeled away by a narrow tube called the condensate line. However, if this line is clogged by dust, debris, or mildew growth, moisture will accumulate and could drip through the vents. You can often clean the condensate line with a solution of bleach or vinegar, so it will drain the excess liquid.

Refrigerant Leak

Air conditioners use refrigerant to transfer heat outside from indoors. A hole in the refrigerant line can result in dripping moisture and a system failure. If you notice drips just as the air conditioner stops blowing cold air, it is likely a refrigerant leak. You'll need air conditioner repair to mend the hole and a fresh charge of refrigerant for the AC to start blowing cold air again.
