This home in Oakton Virginia had high energy bills from constantly running the heating and cooling system for the home at different times of year. After a free home performance evaluation it was determined to be partially due to the HVAC duct system. Metal duct work ran through the attic. In the summer this attic could get up to 130 degrees and in the winter the temperature could drop to 10 degrees. Pumping hot air through a cold metal duct in the winter resulted in the air cooling as it travelled through the ducts and not being able to heat the rooms of the home as well as needed. Pumping cold air through a hot metal duct system in the summer resulted in air that was not as cold as it needed to be to cool off the rooms in the home.
Spray foam encapsulation of the duct systems creates and sealed and safe environment for the conditioned air to travel through and helps that air maintain its intended temperature.
