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

Wisler Plumbing, Heating, Cooling & Electric does not publish a price for HVAC UV light installation because this specific service is not listed on our site. In general, when UV air treatment is quoted, cost varies by lamp design, how it integrates with your air handler, and the labor required for mounting and power. We do provide indoor air quality solutions tied to system maintenance and air duct sealing, and our inspection-first process delivers a clear estimate if UV or another option is the better fit. We routinely serve homeowners around Salem and Roanoke, so an on-site assessment can confirm the right path for your air quality.

Expect an estimate to consider:

• Access and space at the coil or supply plenum
• Number of lamps or coverage points
• Electrical availability and wiring needs
• Replacement-bulb life and maintenance plan

If you’re exploring UV, start with a maintenance check or inspection to compare it against duct sealing and other IAQ steps.
