Overview
Your ductwork is the circulatory system of your home, and when it leaks, you’re throwing away as much as a third of every dollar you spend on heating and cooling. But because most ducts are hidden behind walls, above ceilings, and under floors, you’d never know. At Green Seal Energy, we fix hidden duct leaks with Aeroseal — a patented, computer-controlled aerosol technology that seals your ducts from the inside out. Developed at Lawrence Berkeley National Laboratory with funding from the U.S. Department of Energy, Aeroseal has been used to seal over 300,000 homes worldwide. As a certified Aeroseal Authorized Dealer, we bring over 20 years of home performance expertise to every Kansas City home. The process is fast, non-invasive, and proven to reduce duct leakage by up to 95%. No cutting open walls, no messy mastic, no guesswork — just a measurable, verifiable result.
Education
Aeroseal is an advanced duct sealing technology that seals leaks from inside your HVAC ductwork using a patented non-toxic aerosol mist. Rather than trying to find every tiny crack and gap by hand — which is impossible for ducts buried behind drywall — our technicians seal the system and pressurize it. The Aeroseal computer injects the sealant mist, which flows through the ducts exactly like air does. The mist’s sticky particles are naturally drawn to each leak, building up particle by particle until the hole is completely sealed. The computer tracks the leakage rate in real time, showing the reduction until your ducts meet a precise airtightness target. Once sealed, the flexible sealant forms a durable, long-lasting barrier that moves with your duct system as your home shifts and settles. For homeowners, that means energy waste stops, uncomfortable rooms disappear, and your HVAC system finally performs the way it was designed to. All with zero demolition, zero toxins, and zero disruption to your daily life.
We provide a Duct Leakage Test Report and Certificate showing duct leakage before and after sealing (see sample attached).
