Government buyers are some of the steadiest HVAC customers in the metro. Schools, county buildings, and state facilities don't skip a season — they need preventive maintenance contracts, emergency repairs, and full system replacements year after year. Win one multi-year maintenance contract and it can cover your subscription costs for years. The hard part isn't the work; it's knowing where each agency posts, getting registered correctly, and not drowning in irrelevant alerts. Here's the path.
Do you need a license? Yes — the TDLR ACR license
Before you can bid public HVAC work in Texas, you need a Texas Department of Licensing and Regulation (TDLR) Air Conditioning and Refrigeration Contractor License. It comes in two classes: Class A lets you work on any size unit, and Class B covers cooling systems of 25 tons and under and heating systems of 1.5 million BTUs/hour and under. Most commercial government work — rooftop units on a school, chillers in a county building — pushes you toward Class A.
The license carries endorsements for Environmental Air Conditioning, Commercial Refrigeration, and Process Cooling or Heating; you hold the ones that match your work. To qualify, you need at least 48 months of practical experience under a licensed contractor in the past 72 months, you have to pass the licensing exam, and you must carry commercial general liability insurance for as long as the license is active — at least $300,000 per occurrence for Class A, $100,000 for Class B. The application fee is $115 and the license is valid for one year. Solicitations will ask for your license number and proof of insurance, so get this squared away before you chase a bid.
Where Texas HVAC bids are posted
State agencies post their solicitations on the Electronic State Business Daily (ESBD). The Texas Comptroller's Statewide Procurement Division (SPD) runs the system that connects vendors with state purchasers and contract opportunities. If you want state work, get your firm onto the Centralized Master Bidders List (CMBL) — that's how the state matches vendors to opportunities and sends notifications. This is the feed BidScout reads today, so it's the fastest place for an HVAC firm to start.
City of Austin HVAC work (Austin Finance Online)
The City of Austin classifies HVAC under NIGP commodity code 03100, "Air Conditioning, Heating, and Ventilating: Equipment" — and hundreds of vendors are already registered under it. You register on Austin Finance Online, select the commodity codes that describe your work, and submit your offers electronically through the city's eResponse system. The city also runs a Vendor Academy that walks you through registration and the portal — the City of Austin bids guide covers the full registration flow. The catch with commodity codes is real: pick too few and you miss work, pick too many and the city's alerts bury you.
The commodity-code trap: a buyer might file a chiller-replacement job under HVAC equipment, "building maintenance," or a construction category — and you'll only get the alert if you guessed the same code. BidScout matches on the actual text of each posting, so you see the mechanical work that fits regardless of how a buyer coded it.
School-district and facilities work (Austin ISD on Bonfire)
School districts are one of the most reliable HVAC verticals in the region — aging campuses mean constant mechanical upgrades and maintenance contracts. Austin ISD runs its bids through Bonfire, an e-bidding platform it uses for vendor registration, solicitation notifications, electronic submission, and contract management. The important part: vendors who aren't registered in Bonfire won't be notified of AISD solicitations and can't even view or submit them. Register at the district's Bonfire portal and select the categories that cover mechanical, facilities, and construction work — the Austin ISD bids guide walks through Bonfire registration step by step. Other area districts run their own portals, so treat each one as a separate registration.
Get SMBR certified for an edge
If your HVAC firm is minority-, women-, or disadvantaged-owned, the City of Austin's Small and Minority Business Resources (SMBR) department certifies MBE, WBE, DBE, ACDBE, and SBE firms. To qualify, the business must be at least 51% owned, managed, and controlled by economically disadvantaged individuals, meet SBA size standards, have operated in Texas for at least 90 days, and the owner's personal net worth must be below $2,434,885. SMBR has cut the average review to about seven days, and certified firms recertify every four years. Apply through the certification portal at austintexas.mwdbe.com or call (512) 974-7645.

Tips for winning government HVAC contracts
- Have your license and insurance ready. Solicitations ask for your TDLR license number and proof of general liability up front — missing paperwork disqualifies more bids than price.
- Register on every portal that matters. The state CMBL, Austin Finance Online, and Austin ISD's Bonfire are separate systems with separate logins. If you're not registered, you're not notified.
- Pitch maintenance, not just installs. Multi-year preventive-maintenance agreements are steadier revenue than one-off replacements, and agencies renew them.
- Use the Q&A window. Ask clarifying questions before the cutoff — answers go to every bidder and reveal what the buyer actually wants.
