NIGP 91004: Air Duct Cleaning Services

NIGP 91004 Air Duct Cleaning Services, an Item code, encompasses professional inspection and cleaning of HVAC air distribution systems—ductwork, registers, diffusers, fans, coils, and associated components—across municipal, county, state, and higher-education facilities. State and local governments procure this work to remove accumulated dust, debris, grease, and contaminants, improve indoor air quality and system efficiency, and maintain compliance with fire and exhaust-system standards such as NFPA 96. Work also includes kitchen exhaust hood and filter cleaning at food service facilities, dryer vent cleaning at residential facilities, and air duct accessory installation in building automation and smoke-control systems. The issuing-body mix spans county procurement offices, state departments, city governments, universities, and special-purpose districts, with repeat buyers including the California Department of Motor Vehicles (janitorial and facilities maintenance across multiple locations), the California Department of Corrections and Rehabilitation (hood and duct services at correctional facilities), and county governments in Florida and Georgia.

Recent activity concentrates in California, Florida, Texas, Georgia, and Oregon. Representative opportunities include the County of Orange, California RFP-017-2988904-JC for countywide janitorial services (due October 27, 2026), which encompasses air duct and HVAC component cleaning as part of a broader facilities-maintenance scope; Orange County, Florida ITB Y26-718 for building automation system and smoke/fire alarm air duct accessories at a corrections facility, estimated at $2.89 million with bids due October 20, 2026; the California Department of Corrections and Rehabilitation Master Agreement C5613657-D for hood and duct inspection and cleaning services statewide (due November 9, 2026); the City of Meriden, Connecticut ITB B027-09 for HVAC air duct cleaning at police and fire stations (due September 16, 2026, with mandatory pre-bid on August 26); and the Texas Facilities Commission RFP 0007615 for remediation and restoration services including air duct cleaning across state-owned facilities, with interviews scheduled for June 9, 2026, and contract start September 1, 2026.
