Your HVAC system may be working hard, but if your ducts are leaking, you could be paying to heat and cool your attic, basement, or wall cavities instead of your living space. Studies show that the average home loses 20–30% of its conditioned air through leaky ducts. AI Greenhome's duct sealing service stops those losses and restores full efficiency to your heating and cooling system.
Ductwork degrades over time. Connections loosen, seams separate, and materials deteriorate — especially in unconditioned spaces like attics, crawl spaces, and basements where temperature extremes are severe. Common causes of duct leakage include:
Poorly sealed joints and connections during original installation
When ducts leak into unconditioned spaces, your HVAC system must run longer and work harder to maintain temperature — driving up energy bills and wearing out equipment faster.
Disproportionately high heating/cooling costs despite a functioning HVAC system
Some rooms are consistently too hot or too cold throughout the day
Excess dust, especially accumulating near supply and return vents
Odors, allergens, or humidity problems that seem to come directly from the vents
The system runs for long periods but struggles to reach set temperatures
Obvious structural disconnections, tears, or deteriorated tape on accessible lines
We use a duct blaster test to measure total duct leakage before we start work. This baseline measurement allows us to target the worst areas and document the improvement after sealing.
Our technicians inspect all accessible ductwork in the attic, basement, and crawl space for visible disconnections, damage, and deteriorated seals.
We seal all duct joints, connections, and seams with UL-listed mastic sealant — the industry-standard material that remains flexible and effective for life. We use metal-backed tape for larger gaps.
We re-test with the duct blaster to document the improvement, providing you with before-and-after numbers for rebate applications.
