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

Installing a UV light in an HVAC system is priced after a professional assessment because system layout, access, and electrical needs differ by home. The biggest cost driver is the UV-C equipment choice—single-lamp coil treatment versus whole-duct coverage—followed by how and where it can be mounted. WireNut Home Services provides transparent, written pricing before work begins. Our team serves this region and tunes solutions for Colorado’s dry, high-altitude homes. A tech will also check whether your air quality goals point to pairing UV with filtration or duct sanitization for better results. If your system is newer and space is tight, expect more install planning rather than replacement.

What most affects your final price:

• UV-C grade and number of lamps needed for coverage
• Mounting location, cabinet access, and sheet-metal modifications
• Electrical supply needs (new outlet or wiring at the air handler)
• Add-ons like odor control or duct sanitization during the same visit
