Duct Leakage effects everyone across the United States. Nationally ducts leak an average of 30% of conditioned air into attics and crawlspaces. This means that you are wasting 30 cents of every dollar that you pay to condition either hot or cold air in your home through ducting. This means that you are paying to heat your attic or crawlspaces.
John Owens Services has an internal duct repair system, Aeroseal, that can bring your duct leakage down as low as 2%
