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 in-home evaluation because equipment type, lamp technology, and installation access determine the total. Costs rise with advanced oxidizing UV add-ons or when electrical power or coil access is limited. UV-C air sanitizers inactivate viruses, bacteria, and mold spores 24/7, and techs usually place the lamp to shine on the evaporator coil where biofilm forms. We routinely install these systems across the Denver metro and serve Westminster homes every day. Green Club members receive 15% off indoor air quality systems.

Key price drivers your technician will check:

• Lamp style: standard UV-C vs advanced oxidizing UV
• Single-lamp vs multi-lamp or coil + airstream placement
• Access at the coil or duct and panel space for mounting
• Electrical: existing outlet vs adding new wiring or switch
