Inside the 908th: HVAC/R technicians
Staff Sgt. Tyler Phillips (center) explains how a supply and return water line works to Senior Airman Trevor Lynnwood (left) and Airman 1st Class Clayton Turner, all 908th Civil Engineer Squadron heating, ventilation, air condition and refrigeration technicians, July 9, 2022, at Maxwell Air Force Base, Alabama. Water flows through the supply lines from the building to the chiller, which cools it, then sends the water to the air handler system in order to cool the air that will then be flowed into the building.
