“AC quit on a July Saturday with a house full of family. They were here within the hour and had it cold again before the brisket came off the smoker. Cannot beat having them four miles away.”
McQueeney 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 McQueeney'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 Guadalupe 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 McQueeney summer of constant runtime.
UV handles what is on the coil; it does not lower humidity. In a damp McQueeney home we often pair it with a dehumidifier or duct sealing so the whole moisture problem is covered.
The lake floods, and construction along the shoreline has to sit above the base flood elevation. That affects where the condenser, the air handler, and the panel can go. We place and mount equipment so a high-water event does not take out your whole system, instead of bolting it wherever was easy.



From the waterfront on the chain of lakes to the homes just off FM 725, McQueeney is practically our backyard. A few of the areas we cover:

“Old lake house with wiring from every decade since the sixties. They sorted the whole thing out, resized the panel, and explained it in plain terms. Honest and reasonably priced.”
