NIGP 03155: Hand Tools, Air Conditioning and Heating Service Type (Including Leak Detectors)

NIGP 03155 Hand Tools, Air Conditioning and Heating Service Type (Including Leak Detectors), an Item code, covers HVAC component supplies, preventive and corrective maintenance services, filter replacement, system diagnostics and balancing, emergency repair response, and specialized equipment such as compressors, refrigerants, control boards, registers, tubing, and related refrigeration parts that state and local governments procure to maintain heating and cooling infrastructure across facilities. Issuing bodies span city departments, county governments, school districts, housing authorities, and water utilities; recent activity shows school districts (Cobb County, DeKalb County, Sarasota County, Northside Independent School District in Texas, Goose Creek Consolidated ISD) and municipal facilities departments (City of Waco, City of Lubbock, City of Atlanta, Alameda County Water District) as repeat solicitors. Scope includes both commodity purchases—filters, capacitors, thermostats, chemicals, tubing, and components ordered through standing supply agreements and blanket purchase orders—and service contracts for maintenance, repair, emergency response, and system restoration performed under annual, multi-year, or on-demand arrangements.

Geographic activity concentrates in Texas (multiple cities and school districts), Georgia (county governments and school districts), Florida (school boards and utilities), and California (water districts and public entities), with additional procurement in Michigan, Colorado, and the Mid-Atlantic. Representative recent solicitations include the City of Milpitas IFB 26-229 for five-year blanket purchase orders across five MRO supply categories including HVAC components and maintenance supplies, due August 4, 2026; Northside Independent School District IFB2026105 for maintenance supplies and services in San Antonio, due August 6, 2026; Peach County Schools PE72210 for complete HVAC system and electrical upgrades at Heritage High School, due August 6, 2026; the City of Lubbock ITB for heating and cooling units services and repair under CEAP with bids due July 2, 2026; and Texas Tech University RFP 2026-1182 for comprehensive HVAC maintenance, repair, replacement, and emergency response across 150+ buildings with proposals due July 8, 2026.

Contract structures vary from unit-price or percentage-discount supply arrangements to fixed-fee or time-and-materials service models; prevailing wage, insurance, bonding, and background-check requirements are routine across the code.
