“Old home in town with a tired panel. They upgraded it, kept the character, pulled the permit. Fair flat price and a real window.”
Yorktown 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 Yorktown'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 DeWitt 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 Yorktown summer of constant runtime.
UV handles what is on the coil; it does not lower humidity. In a damp Yorktown home we often pair it with a dehumidifier or duct sealing so the whole moisture problem is covered.
Ranch homes around Yorktown run on electric well pumps, so a rural outage cuts the AC and the water together. We are a Generac dealer and size standby units to carry both, so a storm is not a crisis.



From the older homes in town to the ranch acreage all around, we reach Yorktown on the extended run. A few of the areas:
