Indoor Air Quality
UV Air Purifiers
What UV can and cannot do in PNW HVAC systems — coil hygiene versus miracle marketing.
UV air purifiers in HVAC are best understood as coil and drain hygiene tools in damp Kitsap winters — not magic lamps that replace filters, ventilation, or moisture repair.
Where UV earns its keep
Lamps aimed at the evaporator coil discourage microbial films that thrive when coils stay wet through long heating seasons and shoulder-season cooling. Cleaner coils transfer heat better and smell less musty.
Marketing vs physics
Claims that UV sterilizes the whole house often overreach. Air moves quickly past a lamp; dose matters. Pair UV with filtration and humidity control for real Mechanical Home results.
Install and maintenance realities
Bulbs lose output over time, need annual checks, and must be placed for service access without damaging wiring or plastics. Salt-air corrosion outdoor is separate — UV does not rinse outdoor coils.
When Eagle Pipe recommends UV
Recurring coil slime, musty supply air after moisture is addressed, or as part of a documented IAQ package — not as the first response to a wet crawlspace.
What goes wrong when homeowners wait
Installing UV on a dirty coil without cleaning locks in odor. Ignoring bulb replacement calendars wastes the investment. Using UV to postpone duct or crawl repairs delays the real fix.
Local proof and how Eagle Pipe approaches it
Eagle Pipe scopes UV beside media filtration and moisture work under Lori Tschohl’s Mechanical Home standard — written options, no medical miracle language.

Frequently asked questions
Is UV safe around plastics and eyes?
Installed per manufacturer shielding it is designed for enclosed plenums; techs follow lockout and exposure rules during service.
Does UV reduce energy bills?
Indirectly if coils stay cleaner; it is not a rebate-driven efficiency upgrade by itself.
UV or bipolar ionization?
Different tools with different evidence bases — we explain tradeoffs rather than trendy buzzwords.
