This document is a comprehensive HVAC equipment inventory list for Gwinnett County, Georgia, covering multiple county departments, facilities, and jurisdictions including airports, animal welfare facilities, community resource centers, libraries, police precincts, fire stations, corrections facilities, and administrative buildings. The inventory catalogs detailed specifications for heating, ventilation, and air conditioning equipment across approximately 60+ locations throughout the county, including makes, models, serial numbers, filter types, belt specifications, and refrigerant types for thousands of individual units such as rooftop units, air handlers, heat pumps, chillers, fan coil units, mini-split systems, exhaust fans, and various auxiliary equipment. The equipment spans multiple vintages from 2002 to 2025, with the majority of installations concentrated in the 2015-2025 timeframe, indicating ongoing facility modernization and expansion across the county's infrastructure.

The inventory reveals significant diversity in HVAC system types and manufacturers, with predominant brands including Trane, Carrier, Lennox, Daikin, York, and Mitsubishi across various facility classes and sizes. Notable patterns include widespread use of 410A refrigerant in newer installations alongside older R-22 systems still in operation, particularly in the animal welfare and corrections facilities. The document serves as a baseline asset registry for the county's mechanical systems, with potential applications for maintenance planning, equipment lifecycle management, compliance tracking with environmental refrigerant regulations, and strategic replacement scheduling. The detailed serial number documentation and equipment specifications suggest this inventory was compiled to support capital planning, warranty administration, or potential HVAC service procurements, though no specific contracting timeline, funding amounts, or service requirements are indicated within the document itself.
