UNSPSC 40101818: Process air heaters

UNSPSC 40101818 Process air heaters, a Commodity code, covers the procurement and installation of heating equipment for HVAC system replacement and upgrades across state and local facilities. Recent state and local solicitations reflect actual demand for split heat pump systems, packaged heat pump units, and wall-mounted unit heaters serving municipal fire departments, county facilities, housing authorities, and educational institutions. The code appears in requests for equipment replacement at aging facilities seeking energy-efficient refrigerant systems (primarily R-454B compatible units) and modernized HVAC training equipment at technical colleges. State and local buyers under this code include county governments (Talbot County, Georgia; Dublin Housing Authority in Lee County, Georgia), municipal fire departments, technical college systems, and independent school districts seeking single or multi-unit replacements with associated installation labor and materials.

Geographic activity centers on Georgia and Michigan, with recent solicitations posted by Talbot County and Dublin Housing Authority in Georgia, the Technical College System of Georgia (covering Atlanta Technical College and West Georgia Technical College), and Unionsville Sebewaing Area Schools in Michigan. Representative recent opportunities include Talbot County's March 2026 invitation to bid for two 7.5-ton split heat pump systems with R-454B refrigerant and four ductless 24,000 BTU units (due March 26, 2026); the Technical College System of Georgia's April 2026 eRFQ for six Arcoaire 2.0-ton package heat pumps rated 14 SEER with A2L-compatible R-454B refrigerant trainers (due April 29, 2026, after addendum extension); Dublin Housing Authority's February 2026 invitation to bid for complete HVAC system replacement at a 50-unit residential complex (due March 12, 2026); and Unionsville Sebewaing Area Schools' March 2026 sealed-bid procurement for wall unit heater replacement (due March 17, 2026).
