NIGP 03117: Coils: Chilled or Heated Water, and Direct Expansion

NIGP 03117 Coils: Chilled Or Heated Water, And Direct Expansion, an Item code, encompasses replacement condenser and evaporator coils for chiller and split HVAC systems that state and local governments procure as maintenance, repair, and retrofit components for their facility cooling and heating infrastructure. Recent solicitations show school districts, county governments, and state agencies buying factory-specified replacement coils compatible with existing Carrier, Trane, and Arcoaire equipment on an as-needed basis, as well as new A2L-compatible refrigerant coils to upgrade legacy 410A systems to lower-GWP alternatives. The work includes not only the coil hardware itself—specified by model, fin material, tube configuration, and pressure rating—but also installation labor, system commissioning, and EPA-compliant refrigerant handling where required. Issuing bodies span school districts (Marion County Schools in Florida, Pinellas County Schools in Florida, Atlanta Technical College and West Georgia Technical College in Georgia), county purchasing departments (Williamson County, Texas; Harris County, Texas; Pinellas County, Florida), and state military facilities (Texas Military Department). School districts and technical colleges appear as repeat buyers pursuing term contracts and one-time purchases to stock coils for predictable replacement cycles across their building portfolios.

Recent activity concentrates in the South and Southeast, with documented opportunities in Florida (Marion County Schools' as-needed replacement coil term contract with bids due March 13, 2026; Pinellas County Schools' chiller replacement IFB due July 8, 2026), Georgia (TCSG's procurement of six Arcoaire 2.0-ton heat pumps with A2L refrigerant for ATC and West Georgia Technical College, RFQ due April 29, 2026), and Texas (Texas Military Department's split-system HVAC replacement IFB at Dallas due June 1, 2026). The Marion County Schools procurement (Bid 4171GM) explicitly targets fourteen Carrier and four Trane chiller models, specifying new copper-tube aluminum-fin coils in multiple configurations with firm fixed pricing throughout a one-year term plus three optional one-year renewals, while the Pinellas solicitation addresses a single large chiller replacement at the Oldsmar location with sealed electronic bids and OpenGov portal submission. Opportunities support both commodity purchasing (replacement parts on competitive bid) and integrated system work (new refrigerant-compatible equipment paired with installation and startup).
