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

Installing a UV light in an HVAC system with Plumbing and Heating by Craig, Inc. is priced after an in-home inspection, not at a flat menu rate. The biggest driver is the equipment type and placement within your ductwork or at the coil. We offer an $89 Indoor Air Quality Assessment with same-day service that includes an inspection and a comprehensive report; detailed UV install pricing is provided after that visit. Financing is available for larger installations. We install UV air purifiers for homeowners throughout the Stewart area.

When we price your project, we look at:

• Coil-irradiation vs in-duct UV units and number of lamps
• Access to the air handler and any sheet metal modifications
• Need for a 24V power tap or dedicated service switch
• Ongoing lamp replacement interval and maintenance plan options

Having a licensed tech confirm placement, power, and safety interlocks prevents UV exposure and protects your system. <br/> Updated: 2026-03-10 <br/> Need help in Stewart, MN? Call (320) 204-0428 or book online.
