Breakthrough duct sealing technology reduces duct leakage by 90% AFTER professional manual sealing was first attempted
After aerosealing the ductwork, leakage measured only 22 CFM (supply) and 20 CFM (return). As a result, cooled air now reaches all intended destinations throughout the house, leaving less than 1 degree difference in temperature from room to room. The need to dust was also reduced from one time per week to one time every three weeks. As an added bonus, the homeowner saw his energy bill go down about $46 a month.
