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

HVAC UV light installation pricing is confirmed after an on-site visit because cost varies by lamp type, mounting location, and access to your system. The most common driver is whether you choose a coil-irradiation UV or a whole-duct UV purifier, followed by any electrical or duct access work needed. We install UV Purifiers as part of our Indoor Air Quality services alongside filters, humidifiers, and duct cleaning, and we can integrate with major HVAC setups. Our team regularly serves homeowners in the Renton area with prompt, priority scheduling when appropriate.

Key factors that change the price:

• Single vs dual-lamp UV and brand feature set
• Coil-facing install vs in-duct placement and unit accessibility
• Electrical needs, controls, and safe service access
• Bundling with air filters, humidification, or duct cleaning
