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

The cost to install UV lights in an HVAC system is confirmed after an on-site assessment of your equipment and air quality needs. Price varies most with lamp type and where it’s installed in the system. If your evaporator coil shows biological growth, a coil-mounted UV targets the source more directly than an in-duct lamp. We install and service these IAQ solutions across Greater Boston, including the Belmont area. A $50 off indoor air quality services coupon is available through Mar 31, 2026.

Key factors that set the price:

• Coil-irradiating vs in-duct units, and the number of lamps required
• Electrical access, mounting location, and system accessibility
• System size and materials that affect hardware and brackets
• Bundling with duct cleaning or upgraded filters to reach your IAQ goals
