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

Monkey Wrench Plumbing, Heating, Air & Electric prices UV HVAC light installations after an on-site assessment to match your equipment and airflow needs. Pricing varies with your system’s design and the installation path inside the air handler. We service homes in and around San Marino with tailored indoor air quality recommendations. For comparison, current IAQ specials include an Air Scrubber installed for $1,800 and an Ultimate Indoor Air Quality Package at $3,500.

Key factors that set the final price:

• Coil vs airstream placement and the required mounting hardware
• Single vs dual-lamp kits and UV-C output rating
• Electrical access, switching, and any new wiring needed
• Access constraints or panel resealing if the air handler is tight or corroded
• Lamp quality, replacement interval, and warranty terms

Schedule a quick IAQ assessment so a technician can confirm coil access, power, and lamp sizing before you decide. <br/> Updated: 2026-03-11 <br/> Need help in San Marino, CA?
