How do you keep ductwork from sweating in a crawl space?
How do you keep ductwork from sweating in a crawl space?
The primary ways to stop ducts from sweating is to raise the surface temperature of the ducts or to lower the dew point of the air surrounding the duct by some form of dehumidification. The dew point of air is the temperature at which the amount of water vapor in the air is the maximum amount the air can hold.
