When Marion families ask who we'd call for air quality testing, 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.

Fill this out and we'll call you back shortly to confirm your appointment.

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.
Marion sits where Hill Country pollen meets South Texas heat and humidity. That combination loads ductwork with allergens, feeds mold in damp sections, and makes your system push harder for the same comfort — which is exactly why local homeowners stay on a regular service rhythm.
Simple, honest, and done in one visit.
Call or use the form — we'll schedule a visit that fits your day.
We assess the air and inspect the system that moves it — ducts, coil, and filtration.
You get the findings, the photos, and what they mean for your family — no jargon, no scare tactics.
Any recommended work comes with a written quote. There's never pressure to act on the spot.
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 assessments take about an hour, including the system inspection and the walkthrough of your results.
Yes — and it's the smartest order: test and inspect first, then clean with the full picture in hand. Many Marion homeowners book both in a single visit.
We assess the overall picture: airborne dust load, indoor humidity (a big factor in Marion's climate), visible microbial growth in the system, and the condition of the ducts and filtration that your air passes through every day.
Your Marion assessment starts with our free system inspection — call (210) 790-3600 and we'll explain exactly what's included and give you a firm price for anything beyond it, in writing, before we begin.
