HVAC
U.S. Air Force Airman 1st Class Paris Kimble, 23d Civil Engineer Squadron, repairs a ventilation system during a phase II operational readiness exercise at the field training exercise site Feb. 15, 2012, at Moody Air Force Base, Ga. After an electrical control unit failed, the heating, ventilation, and air conditioning unit was called to repair the ventilation system malfunction. The HVAC team was evaluated on how efficiently they can work while wearing the chemical warfare gear. Airmen are preparing for an operational readiness inspection that will take place this spring.
