Government contracts for hvac contractors in New Hampshire

Hvac contractors contracts in New Hampshire typically cover chiller and rooftop-unit replacements, building-automation (BAS) upgrades, indoor-air-quality remediation, preventive-maintenance contracts, and mechanical retrofits at aging federal facilities. Federal posts in this category fall under NAICS 238220 (Plumbing, Heating, and Air-Conditioning Contractors), and the bulk of the work flows to GSA, the Department of Veterans Affairs, and major DoD installations. Many HVAC IDIQs are reserved for small business and SDVOSB pools, especially on VA campuses.

As of October 20, 2026, New Hampshire has 4 open hvac contractors contracts in our database, with 4 added in the last 30 days. Volume in smaller markets is lumpy: a single base or facility can drive a quarter of annual postings. The most active buyers are Dept of Corrections-NH (1 open posts) and DAS Purchasing (Statewide Bids & Contracts) (1), with the rest spread across other federal civilian agencies, DoD components, and state and local departments active in New Hampshire.

Beyond federal opportunities, much of the hvac contractors work in New Hampshire is posted through the New Hampshire Department of Administrative Services bid portal, with recurring buyers including the New Hampshire Department of Transportation and the University System of New Hampshire. New Hampshire posts most state contracts through the Bureau of Purchase and Property — agency-direct postings are rare. ContractRadar pulls federal postings from SAM.gov alongside state and local feeds so an HVAC contractor doesn't have to monitor each portal manually.
