Lead HVAC Technician

The City of Roanoke is seeking a Lead HVAC Technician to join the Facilities Division of the Public Works Department. In this role, you'll play a key part in helping Facilities sustain equipment to ASHRAE standards, drive greater ROI, and strengthen our sustainability efforts across heating and cooling systems by balancing air and water throughout our buildings.

You'll monitor direct digital control (DDC) software, giving you the ability to remotely adjust systems for precise comfort and cooling and heating performance. You'll also upgrade control systems, giving you better command over system performance and deeper access to performance data, so you can track efficiencies and manage HVAC equipment more effectively.

Using Short Ridge equipment, you'll bring existing systems back into design specifications, cutting costs and reducing energy loss along the way. You'll rely on specialized, calibrated instruments to test, adjust, and balance air and hydronic systems, measuring temperatures, pressures, flow rates, rotational speeds, velocities, and air/water quantities to confirm systems are performing as they should.

You'll also work hands‑on with balancing devices like dampers and valves, adjust fan speeds and pump impeller sizes, and fine‑tune automatic controls such as thermostats and pressure controllers, all to keep systems running at peak efficiency during normal operation.
