NIGP 99247: HVAC System Testing, Balancing and/or Troubleshooting Services

NIGP 99247 HVAC System Testing, Balancing and/or Troubleshooting Services is an Item code under which state and local governments buy preventive maintenance, emergency repair, system balancing, commissioning, and performance diagnostics for heating and air conditioning equipment at facilities ranging from administrative buildings and schools to water treatment plants, correctional institutions, transit facilities, and wastewater operations. The work spans routine inspections and filter replacement through complex rooftop unit replacement, chiller system modernization, and comprehensive testing and balancing to verify system performance against design specifications. Issuing bodies include county boards of commissioners, city purchasing departments, school districts, transit authorities, special-purpose districts (water authorities, sewerage districts, utilities commissions), state agencies, and higher-education institutions. Repeat buyers in recent activity include Gwinnett County (multiple HVAC replacement and maintenance projects), Pinellas County Schools (chiller replacements), Orange County (chiller plant upgrades and HVAC services), and Dallas County (equipment-specific maintenance contracts). Geographic spread shows substantial recent activity in Texas (Dallas, Lubbock, Houston, Lewisville, San Antonio-area), Florida (multiple counties and school districts), Georgia (state and county systems), and scattered activity across California, Wisconsin, Connecticut, Michigan, and other states.

Representative recent opportunities include Dallas County's two-year Vertiv HVAC maintenance contract (ITB 2098813, due July 29, 2026) covering 24/7 support and four-hour emergency response for three datacenter units; City of Bartow, Florida's multi-award HVAC installation, repairs, and emergency services ITB (26-22, due August 5, 2026) with hourly rates for regular, after-hours, and emergency response across city facilities; Madison Metropolitan Sewerage District's rooftop unit replacement (sealed bid, due July 30, 2026); Gwinnett County's correctional-institution kitchen HVAC modification project (BL096-26, due August 12, 2026); Orange County Transportation Authority's preventive maintenance and repair services across seven facilities under prevailing wage requirements (IFB 250132, estimated $490,000 over two years); Texas Health and Human Services Commission's as-needed maintenance at Austin State Hospital (due July 23, 2026) with mandatory 32.9% VetHUB utilization; Orange County, Florida's $3,000,000 Administration Center HVAC chiller plant upgrades (due July 30, 2026); State of Texas testing, adjusting, and balancing IDIQ contract (due July 27, 2026); and Texas A&M University System's master services agreement for TAB services with 2% VetHUB subcontracting goal (due July 10, 2026). Prevailing wage requirements apply frequently under Davis-Bacon compliance or state labor codes; many procurements require EPA 608 refrigerant certification, state HVAC contractor licenses, and performance/payment bonds. Set-asides and preferences vary by issuing body and project type, with some jurisdictions applying VetHUB goals, DBE participation mandates, or state resident preferences. Activity remains consistent across maintenance renewals, emergency repair frameworks, and major capital replacements.
