Dumfries VA Duct Spray Foam Duct Insulation

This Dumfries VA home had condensation along the HVAC ducts (duct sweating) due to external heat making its way into the home via uninsulated rim joists on the side of the house.  Hot air from outside was working against the cold air moving through the HVAC ducts and causing the duct sweating which was showing itself as water spots on the basement ceiling drywall and mold.  Our production team encapsulated the duct with spray foam and then administered Aero Seal to the inside of the system to eliminate the opportunity for conditioned air to escape.  This process will stop the duct sweating and keep the conditioned air inside of the HVAC duct from experiencing any external temperature influence.  The air will reach the rooms it is intended to cool or heat and reduce the need for the HVAC system to work as hard as it had been. Improved comfort and reduced energy cost for the homeowner.
