Your AC coil is the perfect mold incubator - it sits dark, cold, and wet from June through September. A coil-mounted UV-C lamp shines germicidal light directly on the coil and drain pan, killing mold and biofilm as fast as it tries to grow. The result: no more musty-AC smell, a cleaner-draining condensate line, and far fewer airborne mold spores in your conditioned air.

UV-C vs. whole-home air purifiers - what's the difference?
UV-C kills living things on the coil - mold, bacteria, biofilm, viruses. Whole-home air purifiers capture non-living particles - dust, dander, pollen, smoke. They solve different problems and most Plainfield homes we service end up with both. Start with an IAQ assessment and we'll tell you which one (or both) you actually need.

UV air purifier installation for Plainfield homes
Indiana's humidity swings - 90% outdoor in July, 60%+ in older crawlspaces year-round - make Hendricks County a mold hotspot. UV-C at the coil is the most reliable way to keep mold off the wettest, darkest surface in your HVAC system. We install on every common air handler brand: Daikin, Carrier, Trane, Lennox, Goodman, Bryant, Rheem, and more. Pairs naturally with annual AC service and a whole-home dehumidifier for stubborn basement humidity.
