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

HVAC UV light installation cost depends on your system and setup, and SALT Plumbing Air & Electric confirms final pricing after an on-site inspection. The biggest cost swing is the type of UV system (coil-irradiation vs in-duct air treatment) and how accessible your air handler and ductwork are. Our techs regularly install purification add-ons in homes around Jarrell and greater Austin, and we size and place UV lights to protect coils and treat moving air without restricting airflow. SALT+ members receive Plus Member Pricing on new installations.

What most affects price:

• UV configuration: single-lamp coil light vs dual-lamp or in-duct units
• Electrical needs: new outlet or disconnect vs existing power nearby
• Access: tight attics, sheet-metal modifications, or service panels
• Features: ozone-free designs, lamp life, monitors, or safeties
• Maintenance: bulb replacement intervals and warranty terms
