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

Installing a UV light in an HVAC system at Berkeys is offered at $1,975 per system when bundled with Professional Duct Cleaning. Most price variation comes from your air handler’s design and the UV unit style that best fits it, and final pricing is confirmed after an on‑site inspection. We also bring North Texas climate experience to right-size IAQ solutions for local homes. Financing is available with approved credit; this limited-time offer is subject to change.

Expect the price to change based on:

• UV configuration (coil-sanitizing vs in-duct, single vs dual lamp)
• Access to the coil or plenum and any needed metal work
• Whether a nearby power supply or service switch must be added
• Optional add-ons like duct sanitizing or upgraded filtration

For safe, effective operation, have a licensed HVAC pro position the lamp to treat the coil without exposing wiring or plastics. <br/> Updated: 2026-03-13 <br/> Need help in Prosper, TX?
