HVAC UV Lights in San Marcos

Here is what a coil UV light does and why Hays County humidity makes it worth it.

Mold at the Source

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.

A Cleaner, More Efficient Coil

Biofilm on the coil insulates it and drops efficiency. Keeping it clean with UV helps the system cool better and last longer through a San Marcos summer of constant runtime.

Best Paired With Humidity Control

UV handles what is on the coil; it does not lower humidity. In a damp San Marcos home we often pair it with a dehumidifier or duct sealing so the whole moisture problem is covered.

Why San Marcos Homes in Particular

The older neighborhoods around Belvin Street and downtown have homes that predate central air entirely. That means undersized panels, two-prong outlets, ungrounded circuits, and sometimes knob-and-tube still in service. We modernize it safely and pull the City of San Marcos permit so it is documented for resale.
