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

The cost to install a UV light in an HVAC system varies by home and is confirmed after an on-site assessment. The biggest driver is the UV style (in-duct air-sanitizing vs coil-sanitizing) and how your air handler or furnace is set up. We install both options and often see pricing change with cabinet access and electrical needs; on older tight coil cabinets, we sometimes add a UV-safe mounting point to prevent light leaks. We regularly perform these installs for homeowners in the Westfield area.

What typically drives price:

• UV type and coverage (single lamp vs multi-lamp or multiple zones)
• Access and retrofit complexity at the duct or coil location
• Electrical needs (dedicated outlet or service switch additions)
• Add-ons like pairing with HEPA/electrostatic filtration or a maintenance plan

Ask for a tech to evaluate placement and electrical before quoting so your price reflects the actual install time and parts. <br/> Updated: 2026-03-12 <br/> Need help in Westfield, IN? Call (317) 795-1651 or book online.
