La Coste's small-town homes southwest of San Antonio sit in open, dusty country where vent buildup happens fast.
South Texas heat means La Coste 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 La Coste ductwork collects more — faster — than most homeowners realize.
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 La Coste homeowners ask us most.
Most La Coste 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 La Coste homeowners book both in a single visit.
We assess the overall picture: airborne dust load, indoor humidity (a big factor in La Coste's climate), visible microbial growth in the system, and the condition of the ducts and filtration that your air passes through every day.
Your La Coste 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.
