AC INFO.xlsx

This is an Air Conditioning (AC) inventory and assessment spreadsheet documenting the status of split-unit HVAC systems across multiple buildings at Joint Base Lewis-McChord. The spreadsheet tracks 16 nonfunctional ductless heat pump A/C units requiring replacement, organized by building location (Buildings 9160/9162, 9190, 9934, and 9983), with detailed technical specifications including evaporator and condenser models (predominantly Mitsubishi MSZA17NA, Daikin FTX/FHQ/FCQ series, and other manufacturers), refrigerant types (primarily 410A), thermostat settings (ranging from 59-101 degrees), and current operational status (RED for faulty, GREEN for functional). Each unit entry captures the make/model, room number, fault descriptions, condenser location, and access requirements (roof access, ladder access, or no roof access needed).

The inventory reveals widespread system failures requiring remediation, including error codes (E4, 1102, 5-blink codes), condensation issues, battery-depleted remotes, power failures, and fan inoperability. Additional maintenance issues documented include full condensation pipes, water damage, filter cleaning needs, and lightning protection removal concerns. This technical assessment directly supports the replacement contract H9242126QE047, which requires contractors to remove all 16 nonfunctional units and install new cooling-only split A/C systems with external condensation pumps, purge and test drain lines, and perform full testing. The performance period runs September 28, 2026 through November 12, 2026, with a mandatory site visit on September 18, 2026 at 1:30 p.m. (PDT) at 9190 Cramer Ave and a written questions deadline of September 21, 2026 at 5:00 p.m. (EDT).
