UNSPSC 47121811: Duct cleaning machines

UNSPSC 47121811 Duct cleaning machines is a Commodity-tier code covering professional air duct and dryer duct cleaning services, equipment remediation, and system inspection work at public facilities. State and local governments purchase these services to maintain HVAC system performance, improve indoor air quality, and comply with safety standards across municipal buildings, correctional facilities, fire and police stations, water utilities, and transit authorities. Work typically includes pre- and post-service video inspection, cleaning of accessible ductwork components such as registers, diffusers, and blower assemblies, and specialized certifications (Air Systems Cleaning Specialist, NADCA, IICRC) are standard requirements. Counties, cities, and special-purpose districts are the primary issuing bodies, with individual municipal departments or facilities management operations driving procurement.
