HVAC UV Lights in Castroville

Here is what a coil UV light does and why Medina 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 Castroville summer of constant runtime.

Best Paired With Humidity Control

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

Why Castroville Homes in Particular

Old Alsatian homes with thick walls and steep roofs rarely have ductwork that reaches everywhere. A ductless mini-split adds real, zoned cooling without tearing into a historic structure — the right answer for a house that was never built for central air.
