NIGP 03170: Odor Control Equipment, Duct Air (Including Ozone Type)

NIGP 03170 Odor Control Equipment, Duct Air (Including Ozone Type), an Item code, encompasses air duct cleaning, maintenance, and remediation services that state and local governments procure for facility operations and environmental compliance. State and local buyers under this code range from county departments of public works and water resources to state facility commissions and municipal departments, soliciting duct cleaning and air system remediation as part of broader facility management, wastewater treatment, and remediation programs rather than as standalone equipment purchases. The work includes routine dryer duct and air duct cleaning, preventive maintenance programs, air system assessment, and specialized certifications such as NADCA Air Systems Cleaning Specialist Certification and IICRC remediation credentials.

Recent activity shows concentrated procurement in Texas and California, with notable state-level involvement. The Texas Facilities Commission issued RFP 0007615 on April 13, 2026 (due May 28, 2026) for remediation and restoration services across 81 state-owned facilities including air duct cleaning, requiring NADCA Air Systems Cleaning Specialist Certification and emergency response capability within two hours, with a mandatory 26% HUB subcontracting goal and contract term through August 31, 2028 with two optional two-year renewals. The County of San Mateo, Department of Public Works, posted RFP 2026RFP00238 on May 4, 2026 (due May 22, 2026) for dryer duct maintenance and repair services including as-needed air duct cleaning across county shelters, correctional facilities, and a navigation center, with a not-to-exceed contract value of $375,000 over five years and local business preference applied. Neither solicitation names a specific equipment budget or odor-control product specification; procurement activity centers on service delivery, labor, and certifications rather than equipment acquisition.
