Where should HVAC UV light be installed near the evaporator coil?

HVAC UV lights should be installed inside the air handler, mounted adjacent to the evaporator coil. This placement exposes the coil to germicidal UV‑C light (254 nanometers) that disrupts biological contaminants at their source. Our technicians regularly install and service these systems for West Valley homes and verify performance after installation.

For best results, a pro will typically:

• Aim the lamp for unobstructed line‑of‑sight to the coil surface.
• Position it to minimize shadowing from the housing or filter rack.
• Leave clear access for annual bulb replacement during maintenance.

Turn off power before opening the air handler and have a technician confirm placement and wiring.
