Alexandria VA Sweating Ducts fixed with Spray Foam Insulation

This Alexandria VA home had comfort issues due to a lack of efficient air seal in the attic and inefficient insulation.  In addition to that, the HVAC ducts were sweating causing water to accumulate and damage the ceiling/drywall above several rooms.  When an HVAC system is pushing cold air through a metal duct that passes through a hot attic space, it will create condensation (sweat) which can accumulate and cause damage or even promote the growth of mold.  We used spray foam to insulate sections of the duct work.  This will help keep the ducts from heating up and let the cold air pass through without issue,
