When Marion families ask who we'd call for duct sealing, the answer is simple — us. Green Air Duct Club has served the San Antonio area since 2009 with one rule: show the customer photos, quote one honest price, and don't get paid until they're happy.

Marion's small-town homes between San Antonio and Seguin sit in farm country — dust is a way of life, but it doesn't have to live in your vents.
Between the cedar pollen blowing off the Hill Country, summer humidity that never quite leaves, and dust from the construction that seems to be happening on every Marion street, the air inside a Marion home works hard for its living. Your ducts collect all of it, quietly, until the vents start telling the story.
Simple, honest, and done in one visit.
We inspect your duct system and show you photos of the leaks and disconnected joints we find.
You get a clear, itemized quote. Nothing is sealed — or charged — until you approve it.
We seal joints, seams, and connections with mastic systems built to last in Texas attic heat.
We re-check airflow room by room so you can feel the difference where you actually live.
Every home is different, so we inspect first — free — show you photos of what we find, and give you one firm written quote. The price we quote is the price you pay.

What Marion homeowners ask us most.
Most Marion homes take half a day to a full day, depending on how much ductwork is accessible and how many leaks we find.
It can — and booking sealing together with your $99 duct cleaning in Marion is the most efficient route, since the system is already open and inspected.
The U.S. Department of Energy estimates typical duct systems lose 25–30% of the air they carry through leaks and poor connections. In a Marion home running AC most of the year, sealing those leaks is often the fastest payback in the whole system.
Every Marion home is different, so we inspect first and give you an honest written quote before any work. The inspection itself is free, with photos and zero pressure.
