“Old panel, long service run, lights flickering. They found the voltage drop, upgraded the panel, added surge protection. Knew the rural stuff cold and were fair about it.”
Fischer 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 Fischer'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 Comal 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 Fischer summer of constant runtime.
UV handles what is on the coil; it does not lower humidity. In a damp Fischer home we often pair it with a dehumidifier or duct sealing so the whole moisture problem is covered.
Power travels a long way to a Fischer home, and voltage drop plus exposure to weather is hard on wiring and panels. We test the full run, upgrade tired panels, and add surge protection — important anywhere on the ERCOT grid, more so on an exposed ridge.



From the ridgetop homes along the Devil's Backbone to the ranch acreage around Fischer Store, we make the drive out here. A few of the areas:

“Propane furnace quit in a cold snap and we are about as far out as it gets. They came, fixed it, did the CO check, flat price. Grateful somebody reliable covers Fischer.”
