Air Condtions Ducts In Attic Wet

Not enough insulation on the ducts themselves.

Air condtions ducts in attic wet.

Condensation forms when warm humid air comes into contact with a colder surface like your air conditioner s ductwork. If you have central heating and or air conditioning in your home the warm or cool air is delivered to each room through a system of connected ducts and vents. Basically when the cold air from your air conditioner mixes with the warm moist air in your attic condensation happens. If you live in a consistently humid climate a dehumidifier can help keep the air.

Flooded wet or iced air ducts causes cures for wet or corroded air conditioning duct work. Poorly insulated or uninsulated ducts and humid air coming in contact with cool ductwork. And then it drips down onto your ceiling creating nasty water marks. In this case you ll need extensive duct cleaning with mold remediation and you ll want to make sure to seal up the leaks in the ducts to prevent the problem from returning.

If they are located in your attic be sure the area is properly insulated and any cracks or holes are sealed.

The same thing can happen with your ac system and vents. The 1 800 square foot brick ranch in climate zone 4 dates from the 1960s but the previous owner installed both a furnace and ductwork in the attic just four years ago.

If your ductwork isn t well insulated then it will be the temperature of the air passing through it so when your air conditioning is on cool air makes the metal ductwork cold. The difference between the cold air in the ducts and warm air in the walls can cause moisture to condense on the ducts giving mold a perfect environment to grow. If ducts are located in a crawlspace underneath your house cover the soil to reduce moisture. There are essentially two reasons by ductwork sweats.

The photo at page top shows a very rusty air conditioning ductwork register and a careful look into that system of metal duct work found additional heavy rust in the duct system along with lots of debris. I was wondering is there any figures on the expected energy temp lose. 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 unconditioned space also houses his hvac system.

I live in montreal and had a lennox air conditioner and ducts installed in the attic. Keep ducts spaced apart so air can flow between them. The air ducts for a central hvac systems are typically located above a home in the attic or upper crawl space or underneath a home in the space between the foundation and the floor so. Ted has more than a few cobwebs in his attic.
