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

The cost to install a UV light in an HVAC system is confirmed after an in‑home evaluation because equipment choice and installation complexity determine final pricing. Most of the variation comes from the UV technology you choose (for example, a whole‑home purifier like the Reme Halo versus a basic coil UV), how accessible your ductwork and air handler are, and whether any electrical or sheet‑metal changes are needed. We regularly perform these installs in Evanston and nearby North Shore homes, including older systems where the Reme Halo is compatible with SpacePak and Unico. A common field finding is that tight mechanical rooms add labor time, while an existing service opening and nearby power simplify the job. Free quotes are available for Reme Halo installation and indoor air quality consultations.

Your technician will finalize pricing based on:

• Specific unit type and size matched to your airflow
• Mounting location (supply/return) and need for a new access panel
• Electrical availability and required switch or outlet additions
• Any add‑on IAQ upgrades requested at the same visit

Do not open ductwork or look at a powered UV lamp, as UV‑C can harm eyes and skin.
