“Older home near the courthouse with a tired panel. They upgraded it, pulled the permit, kept the character. Straight, clean work.”
Karnes 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 Karnes 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 Karnes 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 Karnes City summer of constant runtime.
UV handles what is on the coil; it does not lower humidity. In a damp Karnes City home we often pair it with a dehumidifier or duct sealing so the whole moisture problem is covered.
The established homes near the courthouse often run undersized panels and dated wiring. We modernize the electrical safely, keep the character, and bring it to NEC 2023 code with a permit.
