Also, all Aeroseal air duct certified technicians are qualified to run a program made by the Environmental Protection Agency (EPA) called “Duct Investor”. Duct Investor takes a comprehensive list of variables and provides a homeowner with the best available estimate of what they should realize in cost savings.
We block off the registers with foam or plastic.
We Inject a UL tested and approved aerosol into the duct system.
Since the air has no place to go except out through the leaks (the registers are blocked), the sealant material is deposited precisely at the air duct holes or cracks where leakage occurs. The make-up of the particles is such that they stick to each other when under pressure (like being forced through a hole). Layers build up until the entire hole is sealed.
A computer and sensors are used to measure and control the progress. The technology is patented from the University of California and the process is endorsed by the Environmental Protection Agency.
We perform a postseal test to measure improvements.
A complete report and certificate is printed on the spot to provide a record of improvements.
