La Coste's small-town homes southwest of San Antonio sit in open, dusty country where vent buildup happens fast.
La Coste 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.
We inspect your coil and air handler and show you photos — UV helps most where growth and odor are starting.
One installed price, in writing, before we touch anything.
We mount and wire the UV unit at the coil or in the supply duct for maximum exposure.
We show you the installed light, explain bulb replacement, and answer every question.
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 UV bulbs are rated for about a year of continuous use (some models up to two). We'll tell you exactly which bulb your La Coste installation uses and when to change it — it's a simple swap.
The light is fully enclosed inside your HVAC system — nobody looks at it or is exposed to it. It produces no chemicals and leaves nothing in the air but cleaner-feeling air.
The UV-C light is mounted inside your system, shining on the coil and the air passing over it. It works continuously against mold growth on the coil and airborne microorganisms — a quiet, always-on layer of protection for your La Coste home's air.
We inspect your system first — free — and quote one installed price in writing. The right unit depends on your system's size and layout, and we'll explain the options without pressure.
