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

Installing a UV light in an HVAC system is priced after an on-site evaluation because costs vary by your equipment setup, installation method, and the specific germicidal UV product selected. The biggest swing usually comes from whether your system allows a simple coil treatment or needs a higher-output solution for the supply plenum. We install germicidal UV lights as part of indoor air quality upgrades across the Roanoke area. Members of our Sure Home Advantage plan pay $49 for heating and cooling diagnostics, and available specials or financing may apply after we size the job.

Your final quote typically reflects:

• Access to the coil or plenum and working space at the air handler
• Need for 24V/120V power, transformer, or control interlock
• Single vs. dual-lamp output and lamp life/warranty
• Add-ons like view ports or safety switches if required

Schedule a short assessment so a technician can verify placement, power, and lamp sizing before we quote. <br/> Updated: 2026-03-09 <br/> Need help in Vinton, VA? Call 5406851594 or book online.
