Studies estimate that the average American home loses 20 to 30 percent of conditioned air through leaks in the duct system before it ever reaches living spaces — and in Austin's extreme summer heat, that means your AC is working significantly harder than it needs to while your energy bills climb unnecessarily. Smith Family Austin Fresh Air Duct provides professional air duct sealing that locates and closes every leaking joint, connection, and penetration in your accessible ductwork.
Our technicians perform a visual inspection of all accessible duct runs in attics, crawlspaces, and mechanical rooms, identifying separations at joints, loose flex duct connections at boots and plenum collars, and degraded mastic or tape seals. We apply UL-listed foil tape and water-based mastic sealant — not standard cloth duct tape, which deteriorates rapidly in Austin's attic heat — to create durable, long-lasting seals at every identified leak point.
Sealing your ductwork delivers a measurable return on investment through lower utility bills, more even room-to-room temperatures, reduced runtime on your HVAC equipment, and better indoor humidity control. It also prevents unconditioned attic air — which in Austin summer can reach 130°F — from being pulled into your living spaces through return duct leaks, improving both comfort and indoor air quality significantly.

Common Questions
How do you find leaks in my ductwork without expensive equipment?
We perform a hands-on visual and tactile inspection of all accessible duct runs, checking joint connections, flex duct terminations, and boot connections while the system runs. We can feel and hear airflow escaping from leaking joints. For systems with suspected major leakage, we may recommend a blower-door style pressure test performed by a third party.
What is the difference between mastic sealant and duct tape for sealing ducts?
Mastic is a water-based paste that hardens into a flexible, durable seal that holds up in extreme heat — essential in Austin attics. Standard cloth duct tape adhesive fails within a few years at high temperatures. We use UL-listed foil tape and mastic, never cloth duct tape, for all sealing work.
