Castle Hills' mid-century ranch homes sit under some of San Antonio's oldest oak canopy, and their ducts collect decades of pollen and dust.
South Texas heat means Castle Hills systems run 2,500+ hours a year, and Hill Country cedar and oak pollen ride every cycle straight into the ducts. Add construction dust from the metro's nonstop growth and indoor humidity that feeds musty buildup, and Castle Hills ductwork collects more — faster — than most homeowners realize.
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 Castle Hills homeowners ask us most.
Most Castle Hills 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 Castle Hills 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 Castle Hills home running AC most of the year, sealing those leaks is often the fastest payback in the whole system.
Every Castle Hills 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.
