UNSPSC 40101809: Circulation heaters

UNSPSC 40101809 Circulation heaters is a Commodity code covering the removal, installation, and maintenance of commercial-grade heating equipment — principally natural gas unit heaters, boiler and chiller systems, and rooftop HVAC package units — at state and local facilities. State and local buyers under this code include state departments of transportation, city housing authorities, municipal transit agencies, school districts, and county governments. The scope spans new equipment installation with thermostat controls, preventative maintenance and repair of existing boiler and chiller systems across multiple facilities, and full equipment replacement including disconnection, disposal, and system startup and testing. Issuing bodies soliciting under the code range from single-location facility managers to multi-facility maintenance programs serving sprawling property portfolios.

Recent activity concentrates in California and Texas, with secondary activity in Georgia, Colorado, and North Carolina. The California Department of Transportation (Caltrans) posted an IFB (32A0740) on October 13, 2026 for removal, disposal, and installation of 20 commercial-grade power-vented natural gas unit heaters and thermostats at San Joaquin County facilities, with responses due October 29, 2026. The Housing Authority of the City of Alameda issued an RFP (2026RFP701ROOFTOPHVACAHAHD010) on October 1, 2026 for five rooftop HVAC package unit replacements at 701 Atlantic Avenue, with a mandatory bid walk on October 8 and proposals due October 27, 2026 at 4:00 p.m.; the contract runs five years with a full-time superintendent requirement and commercial general liability insurance of $2 million per occurrence. The City of Charlotte posted an RFQ on September 22, 2026 for preventative maintenance and repair services on boiler and chiller systems at CATS facilities, with responses due October 15, 2026. Northside Independent School District (San Antonio, Texas) issued an RFQ for an indefinite quantity contract for electrical work on September 22, 2026, though the electrical scope is tangential to the circulation heater code and does not reflect primary activity.
