FAQ
Where does the UV light actually go?
Typically mounted to shine directly on the evaporator coil — the part of your system that's wet for hours after every cooling cycle, and the most common spot for mold and biofilm to establish inside the equipment itself.
Does UV replace the need for filtration?
No — UV and filtration solve different problems. UV limits growth on the coil surface; filtration captures particles moving through the airstream. Most mold-sensitive households benefit from both.
UV-C placed where the physics works — not where it's easiest to mount
UV-C genuinely neutralizes mold spores, bacteria, and viruses — when it's positioned correctly. Effectiveness depends on intensity and exposure time, which means placement at the evaporator coil (where moisture makes biological growth most likely) and sizing matched to your air handler, not a bulb zip-tied wherever access was convenient. We install UV-C as a targeted layer: keeping the coil itself clean is the primary job, treating passing air the secondary one, and we'll tell you plainly that UV complements filtration rather than replacing it. If a system's real problem is duct contamination or humidity, we'll say that first — a lamp can't sanitize its way past a moisture problem.
