How much does it cost to install UV light in an HVAC system?

HVAC UV light installation cost varies by UV unit type, lamp count, and your system’s layout, so final pricing is confirmed after an in‑home assessment. Most of the price is driven by the UV device (coil-sterilizing vs in-duct), parts, and the labor needed to access and wire your air handler. We install integrated IAQ accessories for homes across the Phoenix Valley, including work near Queen Creek. In our experience, placing the lamp to bathe the evaporator coil while shielding nearby plastics prevents damage and improves results. For persistent coil slime or odors, a coil UV is usually the practical choice; if you want broader airstream exposure, an in-duct unit may make sense.

Key factors that change price:

• UV brand and lamp power or number of lamps
• Required power supply, safety switch, or control integration
• Access limits around the air handler or coil cabinet
• Warranty length and replacement lamp costs
