How Can I Seal a Leaking Air Duct to Improve HVAC Efficiency?
Aeroseal is the most effective way to seal a leaking air duct, sealing up to 95% of leaks from inside the duct. Proper duct sealing can lower utility bills by about 20–30%. The process is non-toxic and non-destructive. Service includes a pre-seal air loss test, minor duct cleaning for adhesion, Aeroseal application through the duct system, and a post-seal test to confirm results. Optional same-day preventative HVAC maintenance is available. We serve Weston and nearby Greater Boston communities.
