FAQs

Frequently asked questions

Still have questions?

Where should HVAC UV light be installed near the evaporator coil?

HVAC UV light should be mounted in the supply plenum just downstream of the evaporator coil, aimed at the coil and drain pan for steady, direct line-of-sight exposure. Most microbial growth starts on the cold, damp coil, so shining UVC there helps keep the surface clean. Technicians in the Boise area often pair this placement with whole-home filtration when better indoor air quality is the goal, and Diamond installs whole-home UV systems that can be combined with filtration as noted on our site.

Look for these placement details during installation:

  • Aim at the wet side of the coil and pan; avoid shadows from sheet metal or wiring.
  • Respect the lamp’s clearance rules and keep plastics and wire insulation out of the beam.
  • Leave clear access for lamp changes and prevent UV spill into the filter area.
  • Seal the access panel to stop light leaks.

Always shut off HVAC power and never look at an operating UVC lamp without proper shielding.

How much does it cost to install UV light in an HVAC system?

Installing a UV light in an HVAC system with Diamond Heating and Cooling is priced after an in-home assessment because equipment options and installation conditions vary. The biggest driver is the UV model and lamp configuration you choose, followed by how accessible your duct or plenum is for mounting. We install Series3 whole-house UVC systems that disinfect airflow at the source, and placement near the evaporator coil often delivers the best biofilm control. We routinely install these across the Treasure Valley, bringing consistent results in both older duct layouts and newer homes. Current savings include 10% off IAQ purchases through 2026-03-31, and the Silver Membership Plan at $19.50/month includes IAQ discounts and scheduled maintenance.

Expect a technician to confirm these before quoting:

  • Single vs dual-lamp or UVC/UVV combo based on airflow and goals
  • Mounting location and any sheet-metal or electrical work
  • Power availability and control options with the blower
  • Lamp replacement interval and access clearance

An on-site evaluation ensures safe placement and the right output for your system.

Can an air purifier be repaired if the UV bulb stops working?

Yes, most UV air purifiers can be repaired when the UV bulb stops working, usually by replacing the lamp. The most common resolution is a simple lamp swap because the bulb is a serviceable part in many whole‑home systems that mount in your ductwork. If a new bulb doesn’t restore operation, a power component (such as the ballast or wiring) may need diagnosis. Whole‑home UVC systems like Series3 units use high‑output lamps designed for in‑duct disinfection, and those lamps are replaceable. We regularly assist Garden City homeowners with UV lamp replacement and system checks to keep air treatment effective. A technician will also verify safety interlocks and airflow so the purifier actually treats passing air. Turn off power before any inspection, and never look at a UVC lamp while it’s energized.
