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

An HVAC UV light should be mounted inside the air handler near the evaporator so the lamp shines directly on the coil and drain pan. This spot focuses on the damp surfaces where microbial growth starts and helps keep the coil cleaner between routine service. Installers usually fasten the fixture to the cabinet wall or a bracket so light reaches the coil face without spilling into supply ducts. Our team often integrates IAQ add‑ons around the Clifton area after checking system layout and compatibility.

Use these placement cues for a proper install:

• Ensure clear line‑of‑sight to the coil surface and the drain pan.
• Mount on the coil side that stays wet after cooling cycles.
• Keep wires and plastics out of UV exposure; use shields provided.
• Leave access to see the lamp indicator and to replace bulbs safely.

Always shut off power before opening panels and have a licensed tech handle wiring and UV safety controls.
