Out US-90 in Medina County, D'Hanis homes face mesquite dust and long cooling seasons that load up ductwork fast.
South Texas heat means D'Hanis 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 D'Hanis ductwork collects more — faster — than most homeowners realize.
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 D'Hanis homeowners ask us most.
No — they work together. Cleaning removes the buildup already in your D'Hanis ducts; the UV light helps keep the coil and air stream from growing it back between cleanings.
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 D'Hanis 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 D'Hanis home's air.
