Condensation On Air Conditioner Duct

Occasionally the secondary condensation pan will also clog and not drain.

Condensation on air conditioner duct.

Condensation on ductwork is a major problem here in the southeast. The colder the air is inside the duct the greater the chance of ductwork sweating. Condensation from the ac ducts can drip onto your home s insulating materials. The more the insulation compresses the less it can insulate your home.

The weight and dampness can compress the insulation reducing the insulation s r value. Air conditioner condensation drain pans the condensation drain line is plugged. If air is able to escape around the ac vents rather than flow through the grates as it should it can cause condensation to build up and drip from the ac vents. Condensation on the ductwork usually means that the area around the air conditioning ductwork is too hot and when it comes into contact with the cold air inside the ducts moisture forms upon it.

Instead of metal choose fiberglass or other insulating materials for your ductwork. Condensation forms when warm humid air comes into contact with a colder surface like your air conditioner s ductwork. Look for air escaping from anywhere besides the grates. 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 problem is particularly prevalent in basements because they often have higher humidity levels. As the humidity level rises outdoors condensation will gradually begin to form on the surface of your air conditioning ducts. 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. It happens because the warm humid air outside the ducts leaks inside where it comes into contact with the cold duct walls.

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. The moisture develops in areas of the home that are typically not cooled but that have ducts in them such as attics and basements. Condensation that forms on the outside of air conditioning ductwork is a common problem in many homes. You can go for a dehumidifier if that helps to reduce.

Keep in mind that your insulation helps you save up to 10 on your yearly energy bills. Here are some tricks to stop condensation on air ducts. In case you have metal ducts make. With the ever increasing popularity of putting the air conditioning ducts outside the conditioned space.

Try to reduce the humidity level in the air near the air ducts. Many contractors and homeowners in humid climates are now experiencing ac vents and duct sweating.
