What to Do About Moisture Around A/C Vents

Have you noticed water dripping from an air conditioning vent or any water stains and yellowing on the ceiling material surrounding an air vent? Don’t panic just yet. Read on to learn more about the common causes of vent moisture and how to deal with them.

Air Leaks around the A/C Vent

If there’s moisture around an A/C vent, start by sticking your hand below it to feel if air is escaping from elsewhere other than the grates. If there’s air coming out of the sides of the vent, you’ll have to seal the leak with caulk.

Clogged Air Filter

An air filter that’s clogged with dust and debris can cause the evaporator coils to freeze over. Once the ice melts, the water can drip out via the A/C vents. If there’s minimal frost, the problem can be resolved by replacing the clogged filter and letting the unit resume normal functioning. You can prevent the problem by changing your filter regularly.

Clogged Condensate Drain Line

Your A/C drain line can become clogged with dirt, dust, and debris. That can make water accumulate within the air vent. It’s easy to troubleshoot the drain line for a clog. Simply go to your condenser unit outside and check whether the drain pan is overflowing or too full. If so, you’ll need to have it cleaned thoroughly.

Low Refrigerant Levels

An A/C unit that’s low on refrigerant can cause vent moisture in nearly the same way as a clogged filter does. If you’re experiencing low airflow or air that isn’t as cool as desired in addition to the water leaking from the air vents, a refrigerant leak is a likely culprit. Refrigerant can harm your health, so the problem should be fixed by an HVAC expert.

Vent moisture and the problems that can follow it like property damage can be prevented by scheduling professional A/C maintenance.
