Revised DOSS Managed HVAC Equipment List.xlsx

This document is a comprehensive HVAC equipment inventory list maintained by the Department of Operations and Support Services (DOSS) for Gwinnett County, Georgia. The inventory catalogs heating, ventilation, and air conditioning equipment across multiple county facilities including administrative buildings, libraries, fire stations, police precincts, correctional facilities, animal welfare centers, and various support facilities throughout the county. The equipment list details over 2,000 individual HVAC units ranging from rooftop units and air handlers to mini-split systems, exhaust fans, and specialized equipment such as chillers and energy recovery units. The inventory includes installation year, manufacturer, model number, serial number, filter specifications, belt types, and refrigerant information for each unit, with equipment spanning from 1985 to 2025. Facilities documented include administrative centers, judicial buildings, libraries in Buford, Centerville, Collins Hill, Dacula, Duluth, Grayson, Hamilton Mill, Lilburn, Mountain Park, Norcross, Peachtree Corners, and Suwanee, along with fire stations numbered 1 through 31 and numerous support buildings.

The inventory serves as an operational and maintenance management tool for tracking equipment performance, refrigerant compliance (including transition from R-22 and R-134A to 410A and R-454B), and maintenance scheduling across the county's diverse real estate portfolio. Equipment manufacturers represented include major HVAC brands such as Trane, Carrier, Lennox, York, Daikin, and Mitsubishi, with significant variation in equipment age and condition. The document indicates ongoing capital replacement and renovation efforts, with numerous facilities receiving new equipment between 2020 and 2025. No specific pricing, contract terms, or procurement details are present in this technical inventory document; rather, it functions as a baseline asset register that would inform future maintenance contracts, replacement planning, and energy efficiency initiatives across Gwinnett County's facilities.
