“Big custom home with three zones and another company just kept resetting the thermostat. Moorhead found the bad damper and fixed it. Finally comfortable throughout.”
Boerne 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 Boerne'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 Kendall 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 Boerne summer of constant runtime.
UV handles what is on the coil; it does not lower humidity. In a damp Boerne home we often pair it with a dehumidifier or duct sealing so the whole moisture problem is covered.
The large custom builds spreading into the Kendall County hills run multiple HVAC zones and big panels. When a zone fails or a damper sticks, half the house suffers. We diagnose the whole zoned system properly — controls, dampers, airflow — not just the thermostat.



From the historic Hauptstrasse district to the custom builds in the hills, we reach Boerne on the extended run. A few of the areas:

“On a well in the hills and the power drops a lot. They sized a generator for the pump and AC and explained everything. Worth it, and honest about the drive.”
