Sources Sought DEPT OF DEFENSE DEPT OF THE AIR FORCE is seeking feedback for a proposed brand-name Class Justification and Approval (J&A) for standardization of HVAC chiller brands at Tyndall AFB, FL, USA. The purpose is to allow each USAF installation to select a standard brand of chiller based on its existing inventory when new/replacement chillers are required. The USAF intends to renew the J&A for another five years to support standardization of its HVAC chiller inventory through natural attrition. Interested parties are requested to respond to this RFI to understand the potential impact on the industry.
