Air Conditioning Vents Condensation

Condensation forms when warm humid air comes into contact with a colder surface like your air conditioner s ductwork.

Air conditioning vents condensation.

Routine hvac maintenance will keep all of the parts of your air conditioner working efficiently. The dew point temperature. Basically as your system s evaporator coil cools warm air that passes over it it absorbs heat and moisture from the air. Condensation or sweating is a common problem with air conditioner ducts.

From there the water is flushed out of your home through a drain pipe line. When the air is pulled in condensation drips from the ac coils to what s called a drip pan. It s a natural process and similar to the way a chilled soda begins to sweat once you take it out of the refrigerator on a hot day. The colder the air is inside the duct the greater the chance of ductwork sweating.

This causes condensation to form. That is when the air conditioner vents sweatingand condensation will form. If condensation accumulates within the air vent it can cause water to drip from the ac vents. Since there is lots of humidity near the air conditioner vent the chance of condensation forming is likely to happen.

It happens because the warm humid air outside the ducts leaks inside where it comes into contact with the cold duct walls. Water vapor that drops out will come in contact with cold surface. As the humidity level rises outdoors condensation will gradually begin to form on the surface of your air conditioning ducts. Long term condensation leads to various issues with your ac system.

If you have hvac ducts made of sheet metal with no insulation or ducts with damaged insulation you re much more likely to develop condensation inside the ducts and also condensation on the ac vents. This colder surface then chills the surrounding air to a temperature below it s dew point which causes the water vapor to condense into a liquid just like on the outside of a glass of iced teas sitting outside on a hot day. It can also form small water pools on the floor in severe cases. This same process is what causes condensation on your ac vents.
