AEDC awards contract to Cookeville firm for HVAC system Published Dec. 29, 2008 By 208152 Arnold Air Force Base, Tenn. -- The U.S. Air Force's Arnold Engineering Development Center (AEDC) has awarded a contract worth $821,410 to Mack Mechanical, Inc., of Cookeville, Tenn., to repair and replace the heating, ventilation and air conditioning system in the Power Control Building at the Arnold Air Force Base in Coffee County, Tenn. "This HVAC system has exceeded its service life and has degraded to the point that replacement is required to properly heat and cool the area," explained Tony Pennington, the Air Force project manager for the job. "The Power Control Building is the central area where the base's power distribution system in monitored and controlled." AEDC is the world's most diverse complex of aerospace test facilities. Since it opened in 1951, its engineers, technicians, craftsmen and support personnel have been involved in the development of nearly all U.S. military and NASA high-performance jets, missiles and space systems. The center's propulsion test cells, aerodynamic and propulsion wind tunnels, space chambers and ballistic missile ranges can simulate virtually every aspect of flight from ground level to deep space. Ground testing reduces risks and saves lives, equipment and money in operational testing. For more information on AEDC, visit the Web site at www.arnold.af.mil.
