As some of you know, Safety King has begun this year doing Aerosealing of air ducts in residential and commercial buildings. Aerosealing is a process of sealing air ducts FROM THE INSIDE that achieves near-miraculous reductions in air duct leakage. This translates into big energy savings and greater heating and cooling efficiency for the property owner. Just last week we Aerosealed the air ducts in the residence of the Johnson family in Ferndale and achieved a 94% reduction in air duct leakage! The computer generated report we gave to Mrs. Johnson is shown below.
