NIGP 03113 Chillers, Heat Exchangers And Receivers is an Item code under which state and local governments solicit maintenance, repair, replacement, and retrofit services for commercial water-cooled and air-cooled chillers ranging from 90-ton to 2,000-ton capacity units serving municipal buildings, courthouses, schools, universities, utilities, and correctional facilities. Recent solicitations reveal a strong focus on chiller plant modernization projects involving complete equipment replacement, system upgrades with variable frequency drives and building automation integration, preventative maintenance contracts, and emergency repair services, with work typically performed by licensed HVAC contractors holding EPA refrigerant certifications and demonstrating experience with major manufacturers including Trane, Carrier, Daikin, and McQuay. Issuing bodies span school districts (Pinellas County Schools in Florida, Houston Independent School District in Texas, Marion County Schools in Florida, Pearl River Community College in Mississippi, Georgia State University), cities (St. Petersburg, Orlando, College Park, Frisco), counties (Williamson County Texas, Orange County Florida, Monroe County Florida, DeSoto County Mississippi, Glynn County Georgia, Volusia County Florida), state departments (Texas Health and Human Services Commission, Oregon Department of Transportation, California Department of General Services, Florida Department of Children and Families), utilities (Gainesville Regional Utilities, Long Beach Public Utilities), and specialized authorities (Harrisburg Housing Authority, Events DC). Solicitation activity concentrates in Texas, Florida, Georgia, and California, with recent opportunities posted across the South and West Coast through July 2026.
