Why do AC vents drip?
Question:
Answers:
The humidity level in your home or office is too high. When warm, moist air contacts the metal vent or the duct on the reverse of the vent, it cools and excess moisture condenses.
The only thing you can do to fix this is to lower the humidity level with a dehumidifier. Increasing the temperature does not help, as the air coming from the vents will be the same temperature, just running less often.
condensation
the cold air from the a/c actually causes condensation, which then drips
AC vents drip due to condensation of warm air that was quickly cooled down by the high level of AC being generated. This is not the case for DC vents.
Because of the condensation of the moisture that is in the air.
It's the same process that happens when you set a glass of ice water on a kitchen counter...in a few minutes, the outside of the glass has small water droplets on it. It's also the same process that forms dew on the morning grass.
It's moisture that the A/C removes from the air
From condensation. It is like a cold drink. The drink is colder than the air around it therefore it causes the condesaton. Same with the a/c The air blowing is usually cooler than the air which causes the same situation.
It's the condensate. To explain:
To cool down the house, refrigerant is pumped through a device which sorta resembles a car's radiator or an electronic air filter. When the warm air hits the cool fins, the same thing happens to the fins as it would a glass filled with ice, water droplets form. In the A/C's case, there is much more volume of air being forced through the fins which will cause, in some areas, a dripping; in other areas, what's kin to a torrent, coming from the A/C. The condensate also explains why the instructions in a window unit tells you to have the unit level and to unplug the holes on the bottom, and in the whole house units the funny plastic line that runs from the unit to either a sump, or outside the house.
Hope this helps.
