NIGP 74055: Refrigerant Gases (Except Ammonia)

NIGP 74055 Refrigerant Gases (Except Ammonia), an Item code, encompasses the procurement of refrigerants for HVAC and automotive air-conditioning systems serving municipal, county, and school district operations. State and local governments buy refrigerants in bulk inventory form—measured in pound quantities and cylinder sizes—and procure refrigerant-handling services bundled with preventive maintenance and repair of chillers, boilers, rooftop package units, air handlers, and school bus air-conditioning systems. The issuing bodies span school districts, cities, counties, and state agencies. Hillsborough County Public Schools and the City of Tampa have both posted active opportunities under this code in recent months; San Luis Obispo County issued a preventive maintenance RFP covering refrigerant-dependent HVAC equipment. Work specifications call for technician certification in refrigerant handling per EPA and MACS standards, with R-134a and R-1234yf systems explicitly named in school bus maintenance contracts and R-22, R-410A, and 4-134A inventory procurements appearing in municipal purchasing activity.

Recent opportunities show activity concentrated in Florida and California, with Texas and Washington also represented through cooperative purchasing vehicles. The City of Tampa's IFB for refrigerant inventory (Solicitation 25P00395, due October 20, 2025, estimated value approximately $35,000) specified 600 pounds of FREON 4-134A in 30 LB automotive cylinders, 300 pounds of R-22 in 30 LB cylinders, and 20 R-410A 25 LB cylinders, with a one-year initial term and two one-year renewal options. Hillsborough County Public Schools' RFP for school bus A/C maintenance and repair (Solicitation 26286RFQDST, due August 7, 2026) requires contractors to service multiple refrigerant types on diesel, electric, propane, and gasoline-powered buses, with a Small Business Encouragement Program participation requirement mandating 20 percent subcontractor reinvestment to SBEP-certified vendors. San Luis Obispo County restricted its HVAC maintenance RFP (Solicitation 05A3037, due October 2, 2026) to certified SB/DVBE vendors only, covering two chillers, one boiler, and multiple air handlers. The Texas Department of Criminal Justice issued Solicitation IW245599 through ESC Region 4 as a cooperative procurement vehicle for school districts statewide.
