How much does it cost to install UV lights in HVAC systems?

Installing UV lights in HVAC systems with Cardinal Heating & Air is priced after an in-home evaluation, because the total cost depends on your equipment and where the UV units will be installed. The biggest driver is the UV configuration (coil treatment vs in-duct air treatment) and how it integrates with your existing HVAC. We routinely perform these installs in the Seattle area and provide a written report of findings before you decide.

For clear estimates, techs look at:

• UV lamp style (single vs dual) and output rating
• Electrical needs or new power supplies
• Access and mounting around the coil or duct
• Brand compatibility and maintenance clearance

Booking an indoor air quality assessment gets you same-day service options and a comprehensive report with exact pricing. <br/> Updated: 2026-03-26 <br/> Need help in Seattle, WA? Call (425) 827-9997 or book online.
