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 quoted case-by-case with Boulden Brothers’ up-front, no-surprise pricing after an in-home assessment. The biggest drivers are the UV product type and how accessible the install location is on your air handler or ductwork. We install these systems throughout the Townsend area with options that target the coil or treat the moving air, depending on your needs. A technician will typically place a coil UV near the evaporator where biofilm forms, while whole-air UV sits in the supply plenum for broader coverage. Members of our maintenance program receive discounts on indoor air quality products, which can lower the final number.

You’ll see the clearest price after we confirm:

• UV style: coil sterilization vs whole-air purifier
• Lamp count and intensity, plus brand features
• Access, electrical availability, and any panel or duct modifications
• Add-ons like ozone-free tech or a service plan
