In South Florida, your evaporator coil is wet nearly year-round — the AC runs almost every day, and condensation is how it dehumidifies your air. A cool, damp, dark cabinet is exactly where mold and bacteria like to grow, and everything that grows there sits directly in your home's airstream.
A UV-C lamp mounted inside the air handler shines continuously on the coil and the air passing over it, limiting that growth at the surface where it starts. It works around the clock alongside your system, so a coil that's been cleaned stays cleaner between visits.
Floriduct mounts and wires the lamp inside the cabinet, positions it where it does the most good, and labels the installation for the next technician. Many customers add a UV lamp during a duct or coil cleaning, and we also repair or relocate existing lamps that were installed poorly.

What's included
What our UV light installation covers
Mounting & wiring
We mount the UV-C lamp securely inside the air handler cabinet and wire it properly — no lamps dangling from the coil or powered by loose cords.
Placement at the coil
The lamp is positioned to shine on the coil surface and the air passing it, where the wet, dark conditions that invite growth actually exist.
Labeled installation
We label the lamp and its power connection inside the cabinet, so the next technician who services the system knows exactly what's installed.
Repair & relocation
Already have a UV lamp that's wired badly, mounted loose, or pointed at nothing useful? We repair or relocate existing units too.
