BidDuty checks SAM.gov and Texas state and city bid boards so you don't have to. Every week you get one short email listing the open HVAC, refrigeration and mechanical piping bids, sorted by due date, with a link to each official notice.
Public bids are scattered across federal, state and city websites. Most contractors don't have time to check them all every week. We do it for you.
Federal opportunities from SAM.gov, the Texas Electronic State Business Daily (ESBD), and city bid pages such as Austin and San Antonio.
HVAC, chillers, boilers, heat pumps, refrigeration, ice machines, mechanical piping and plumbing-mechanical work (NAICS 238220). Expired and duplicate notices are removed.
Sorted by due date, with the agency, set-aside (small business, SDVOSB and so on) and a direct link to the official notice. Short notes flag amendments and odd dates.
Open the official solicitation, check the requirements, and bid. We never stand between you and the agency.
These are real open bids. We checked each one against its official source on Oct 17, 2026. Due times are as stated on each notice.

Open public bids for HVAC, refrigeration, chillers, boilers, heat pumps, ice machines, mechanical piping and plumbing-mechanical work in Texas. Our filters use NAICS 238220 (Plumbing, Heating & Air-Conditioning Contractors), the related federal product/service codes (J041, H341, N041) and trade keywords. We include solicitations, combined synopsis/solicitations, presolicitations and sources-sought notices that are still open.
Every item links to the official notice. We summarize. We don't republish solicitation documents.
No, and no service can promise that. Many local agencies use their own portals, and some require vendor registration. We cover the sources listed above and tell you plainly what we check. Federal HVAC volume in Texas is small at any one time, so most listings come from state and local sources.
No. BidDuty is an independent service. We are not affiliated with, endorsed by, or acting for SAM.gov, GSA, the State of Texas, the Texas Comptroller, or any city, county or agency. Dates, requirements and eligibility can change. The official solicitation is always the final word.
Yes. Every email has a one-click unsubscribe link, and paid plans can be cancelled at any time. Cancelling stops future renewals, and you keep access until the end of the period you paid for.
Some federal bids are reserved for certain businesses, for example Total Small Business or Service-Disabled Veteran-Owned Small Business (SDVOSB). We show the set-aside on each listing so you can skip what you can't bid as a prime. You may still be able to subcontract.
To be awarded most federal contracts, your business needs an active SAM.gov registration (free at SAM.gov). State and city bids have their own vendor registration rules, which are listed on each notice.
