“We run a tasting room and the AC could not keep up on busy weekends. They sorted it out and set up a remote thermostat. They understand visitor business.”
Johnson City humidity turns a dark, damp AC coil into a mold factory. A UV light in the air handler kills it at the source, keeps the coil clean, and keeps that smell out of your air.

Stops coil mold
The evaporator coil is dark, wet, and cool — ideal for mold and bacteria, especially in Johnson City's humidity. A UV light mounted at the coil sterilizes it continuously.
Cleaner coil, healthier air, and a system that runs more efficiently because the coil stays clear.
Call (830) 587-5790Here is what a coil UV light does and why Blanco County humidity makes it worth it.
Mold and biofilm grow on the wet evaporator coil and then blow into the house. A UV light kills them right there, so you are not just masking a musty smell — you are stopping its cause.
Biofilm on the coil insulates it and drops efficiency. Keeping it clean with UV helps the system cool better and last longer through a Johnson City summer of constant runtime.
UV handles what is on the coil; it does not lower humidity. In a damp Johnson City home we often pair it with a dehumidifier or duct sealing so the whole moisture problem is covered.
Johnson City runs on visitors — wine-trail tasting rooms, rentals, and the Christmas-lights crowd — and a hot space costs business. We keep visitor-facing spaces comfortable with reliable systems, remote thermostats, and light-commercial service scheduled around the season.



From the historic courthouse downtown to the wineries and ranch acreage along US-290, we reach Johnson City on the extended run. A few of the areas:

“On a well out on the ranch and the power drops in storms. They sized a generator for the pump and AC. Worth it, and they were upfront on price.”
