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

Installing a UV air sanitizer in an HVAC system is a customized job, and the final price is confirmed after an in‑home assessment. Most of the cost depends on the specific UV model and where it will be placed in your air handler or over the coil. Our technicians first evaluate your system to pick the best location and work cleanly with drop cloths and shoe covers. These systems can reduce up to 99.9% of certain bacteria, viruses, and mold and may reduce HVAC strain. We install these systems throughout the Madison area and recommend annual maintenance to keep performance consistent. First‑time customers can take $25 off UV air sanitizer installation.

Typical price drivers include:

• Single‑lamp vs advanced multi‑lamp designs
• Access to the coil or return plenum and any needed electrical work
• Number of HVAC systems or zones to treat
