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 on-site evaluation because total cost depends on the lamp type, placement, and any add-on purification equipment. Most homes use a germicidal UV lamp at the coil or in the supply plenum, with bulbs that typically get replaced about every two years. For homes wanting odor and gas reduction, a multi-stage purifier such as Lennox Pure Air adds charcoal filtration, UV, and a photocatalyst, with filter, lamp, and catalyst commonly changed annually. We install these systems throughout Southeastern Idaho and frequently service homes near Chubbuck.

Cost depends on:

• Standalone germicidal lamp versus a multi-stage purifier (e.g., Lennox Pure Air)
• Single versus dual lamp and placement (coil, supply, or return)
• Electrical access and service clearance at the air handler
• Duct material and size, which affect installation time

Schedule an in-home inspection to receive a firm quote and confirm the right UV or purification setup for your system.
