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 confirmed after an on-site evaluation because equipment type, mounting location, and electrical access vary by home. Most of the price usually comes from the UV kit you choose (coil-surface or in-duct airstream; single or dual lamp) and the labor needed to access the air handler or plenum. A technician will match lamp output to your system, verify safe placement away from plastics and wiring, and plan power through a nearby outlet or transformer. We also perform IAQ testing in line with EPA guidelines and only recommend UV when it addresses the contaminants actually present. In work across the Portland area, totals shift most when older duct systems need a new service opening or when tight closets limit access around heat pumps.

Expect these factors to influence final price:

• UV configuration: coil vs airstream; single vs dual; standard vs high-output
• Installation complexity: access, cutting panels, mounting method
• Electrical needs: outlet/transformer, interlock, service switch
• Ongoing costs: lamp life and replacement bulb pricing

For safe, effective results, have a licensed HVAC pro confirm placement and shielding to protect wiring and plastics.
