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

The cost to install a UV light in an HVAC system is confirmed after an on-site evaluation because equipment type, mounting location, and electrical access determine the price. Most cost differences come from whether the UV treats the evaporator coil or the air stream and how easy it is to mount and power the unit. We provide final pricing after inspecting your system and clarifying goals like odor reduction or limiting bio-growth. Our technicians regularly assess IAQ upgrades in homes around Anthem to match solutions to existing ductwork and air handlers. Maintenance plan members receive 15% off Indoor Air Quality Products.

Expect your estimate to reflect:

• Single vs dual-lamp or high-output UV configuration
• Access near the coil or supply plenum for safe placement
• Need for a new 120V outlet or transformer tie-in
• Add-ons like a sight glass, status indicator, or app-connected monitor

For an accurate quote, book an in-home assessment so a technician can size and locate the UV safely away from UV-sensitive components. <br/> Updated: 2026-03-14 <br/> Need help in Anthem, AZ?
