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 variable and is confirmed after an on-site evaluation. The biggest cost drivers are the UV lamp type (coil- or duct-mounted, single- or dual-lamp) and how accessible your air handler is for safe installation. HVAC UV Lamps require little maintenance; just replace the lamp bulbs annually. We install and service indoor air quality solutions across the St. Louis metro, so quotes reflect typical local home layouts and installation conditions. For added savings, we offer $55 OFF any indoor air quality product installation (limited-time offer, conditions apply). On most systems, placing the lamp to wash the evaporator coil gives the best payoff because that’s where biofilm tends to grow.
