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

Installing a UV light in an HVAC system with Fix-it 24/7 is priced after an in-home inspection, because equipment type and installation complexity drive the total cost. The biggest cost driver is whether the lamp treats the evaporator coil surface or the airstream, since coil access can add labor and materials. Members of our Green Club receive 15% off indoor air quality systems, including UV‑C options. We regularly install these systems across the Lowcountry, including around Goose Creek, where high humidity often makes coil disinfection a smart add‑on.

If you’re comparing options, look for these factors that change price:

• UV‑C style and number of lamps (single vs. dual)
• Installation location and access at the air handler/coil
• Power availability and mounting hardware needs
• Controller features and future bulb replacement requirements

A well‑placed lamp that bathes the wet side of the coil delivers the most benefit with the least power draw, in our experience. An on‑site evaluation will provide an exact quote and confirm the best lamp placement.
