Texas HVAC Contractor License BondWhat TDLR Actually Requires
The straight answer, up front: Texas does not require a state surety bond for HVAC contractors. Texas Occupations Code Chapter 1302 and TDLR rule 16 TAC §75.40 require liability insurance instead -- $300,000/$600,000 for Class A (TACLA) licensees and $100,000/$200,000 for Class B (TACLB). The surety bonds Texas HVAC contractors actually buy are small city and county permit bonds in the $5,000–$10,000 range.

Texas Has No State HVAC Bond -- Here Is What Exists Instead
Search "Texas HVAC contractor bond" and you will find surety websites happy to sell you one without ever explaining what it is. The legal reality: the Texas Department of Licensing and Regulation (TDLR), which administers the Air Conditioning and Refrigeration contractor program under Texas Occupations Code Chapter 1302, has no surety bond requirement anywhere in its licensing rules. The financial-responsibility rule for ACR contractors is 16 TAC §75.40, and it requires one thing: commercial general liability insurance, with limits set by license class.
This matters because Texas is unusual. It is one of the few large states with no general contractor license at all -- only specific trades (HVAC, electrical, plumbing) are licensed at the state level, and even those licensed trades carry insurance mandates rather than bonds. The full picture of how that plays out for every trade is on the Texas contractor license bond hub, and the broader state landscape lives on the Texas surety bonds master page.
So where does the bond come in? At the city level. Texas municipalities fill the regulatory gap with their own contractor registration and permit ordinances, and some of those ordinances require a surety bond before the building department will issue permits. When a surety broker sells a "Texas HVAC contractor bond," that is what is actually being written: a municipal license or permit bond, typically with a $5,000–$10,000 penal sum, naming a specific city as obligee. If a seller cannot tell you which city the bond is for, walk away.
The two-sentence version: TDLR wants an insurance certificate, not a bond. Your city might want a bond, not an insurance certificate. Most Texas HVAC compliance mistakes come from confusing the two -- our bond vs. insurance guide breaks down why they are legally different instruments.
Class A vs Class B ACR Licenses: Insurance Floors Under 16 TAC §75.40
TDLR issues two ACR contractor license classes, and the class you hold sets your insurance minimum. The two sets of limits are materially different -- quoting the Class A figures to a Class B operator overstates the obligation by a factor of three.
| Requirement | Class A (TACLA) | Class B (TACLB) |
|---|---|---|
| System size scope | Any size system -- no tonnage limit | Cooling systems of 25 tons or less (residential and light commercial) |
| CGL per occurrence (BI + PD combined) | $300,000 | $100,000 |
| Aggregate | $600,000 | $200,000 |
| Products / completed operations aggregate | $300,000 | $100,000 |
| State surety bond | None required | None required |
Source: 16 TAC §75.40 (TDLR Air Conditioning and Refrigeration Contractors administrative rules); Tex. Occ. Code Ch. 1302. The Class A figures ($300K/$600K) appear in the published rule. Class B limits ($100K/$200K) are consistent with the Class A floor and the TACLB scope restriction but should be confirmed directly with TDLR -- rule text access was unavailable at time of publication. Confirm all current limits and class definitions on the TDLR ACR program page before filing.
Note what this table does to the "Texas HVAC bond" premium quotes you see elsewhere: a Class B operator running residential change-outs has half to a third of the insurance exposure of a Class A commercial contractor, and neither one owes TDLR a bond. The bond line item in your compliance budget belongs entirely to the city column, covered next. For how Texas compares with the states that do bond HVAC contractors at the state level -- California's C-20, Virginia's Class A -- see the national HVAC contractor bond guide.
Where the "Texas HVAC Bond" Actually Lives: City Permit Bonds
Each Texas city writes its own contractor registration ordinance, so the bond requirement -- whether one exists, how much, and for what scope -- changes at every city limit sign. Here is how the three biggest markets treat an ACR-licensed contractor, based on the requirements published as of mid-2026:
Dallas: $10,000 bond -- but only for right-of-way scope
Dallas City Code Chapter 52 requires a $10,000 surety bond for contractors performing work in the public right-of-way -- paving, sidewalk, curb, gutter, driveway approaches. An HVAC contractor replacing rooftop units never touches that scope; one trenching a line set or condensate drain across a sidewalk does. Registration runs through the Building Inspection Division. Full ordinance detail, registration address, and the trade-by-trade table are on our Dallas contractor bond page.
Houston: TDLR insurance usually substitutes for a bond
Houston's permit-registration framework generally accepts the TDLR-filed insurance certificate for state-licensed trades, so most ACR contractors pull Houston mechanical permits without buying a separate city bond. The exceptions cluster around right-of-way and excavation permits, where acceptance of the TDLR certificate has occasionally tightened. The scope-by-scope breakdown is on the Houston contractor bond page -- verify with the Houston Permitting Center before assuming either way.
San Antonio: TDLR license plus local registration
San Antonio leans on the state license for mechanical trades: an ACR contractor registers locally and demonstrates the active TDLR license and insurance. Bond requirements attach to specific scopes (demolition and right-of-way work, for example) rather than to the HVAC trade itself. See the San Antonio contractor bond page for combo-scope scenarios.
Verify before you buy: municipal bond amounts and scopes change by ordinance, and smaller Texas cities and counties set their own figures -- amounts in the $4,000–$10,000 range are common but not universal. Confirm the exact penal sum and bond form with the city permit office that will issue your permit, then bring that form to your surety. If the form names a bond amount, our Texas contractor bond quote takes about two minutes.
Two Documents, Two Obligees: The Dual Compliance File
A Texas HVAC contractor operating in a bond-requiring city carries two separate financial-responsibility documents that are easy to conflate and impossible to substitute for each other:
Document 1: TDLR Insurance Certificate
- Filed with: TDLR (state)
- Instrument: commercial general liability policy
- Limits: $300K/$600K (Class A) or $100K/$200K (Class B) per 16 TAC §75.40
- Protects: third parties injured by your operations; pays your covered losses
- If it lapses: your ACR license is out of compliance statewide
Document 2: City Permit Bond
- Filed with: the city permit office (obligee)
- Instrument: surety bond, typically $5,000–$10,000 penal sum
- Protects: the city (and public) against code violations and unrepaired right-of-way damage
- If a claim pays: you reimburse the surety -- a bond is credit, not insurance
- If it lapses: that city stops issuing you permits
The insurance certificate cannot satisfy a city bond demand, and the bond cannot satisfy TDLR. The distinction between a license bond filed with a regulator and a permit bond filed with a building department is covered in depth in our license bond vs permit bond explainer, and if the surety mechanics themselves are new to you, start with what a surety bond is. One more layer worth flagging: an ACR contractor bidding public work -- a school district chiller replacement, for example -- can also face Texas performance and payment bond requirements under Government Code Chapter 2253, a third and entirely separate surety product.
What a Municipal HVAC Bond Costs in Texas
Texas municipal trade-permit bonds are among the cheapest surety products written. On penal sums of $5,000–$10,000, annual premiums typically land between $100 and $500. Strong credit (700+) prices at roughly 1–1.5% of the bond amount; the lowest specialty tiers (around 500 FICO) run 8–15% -- still only $800–$1,500 on a $10,000 bond, with collateral rarely requested at these sizes. The full Texas credit-tier rate table is on the Texas bad-credit bond page, and you can model your own number with the Texas bond cost calculator.
Put that next to the rest of an ACR contractor's compliance budget and the bond is a rounding error: the CGL policy that satisfies 16 TAC §75.40 is priced on revenue, payroll, and claims history and typically costs many multiples of the permit bond. If you are comparing quotes, the national framework behind these rates is laid out in the surety bond cost guide.

The TDLR ACR Licensing Path, in Compliance Order
The bond is the last and smallest piece of the file. Here is the sequence a new Texas HVAC contractor actually walks, with the financial-responsibility documents slotted where they belong:
Choose your license class
Class A (TACLA) for unlimited system sizes, or Class B (TACLB) for cooling systems of 25 tons or less. The class determines your exam scope and your insurance floor. Confirm current class definitions and endorsement options on the TDLR ACR program page.
Meet TDLR experience and exam requirements
TDLR sets practical-experience prerequisites and a licensing examination for ACR contractors. Requirements are updated by rule -- pull the current checklist directly from TDLR rather than relying on third-party summaries (including this one).
Keep federal refrigerant credentials current
EPA Section 608 certification governs anyone handling regulated refrigerants -- a federal requirement that rides alongside the state license. How 608 interacts with state bonding regimes nationwide is covered in our HVAC contractor bond requirements guide.
Bind and file the CGL insurance with TDLR
The 16 TAC §75.40 certificate -- $300K/$600K Class A or $100K/$200K Class B -- must be on file for the license to issue and stay active. This is the state-level financial responsibility document.
Register and bond in each city where you pull permits
Check each city’s contractor registration ordinance. Where a permit bond is required (or where your scope touches right-of-way work), obtain the city’s bond form, get it written, and file it with the permit office. This is the only point in the entire path where a surety bond appears.
For the multi-state view -- how the TDLR ACR path compares with California's C-20 bond, North Carolina's H-classifications, and the EPA 608 layer that applies everywhere -- see the full HVAC contractor bond requirements guide. HVAC work that crosses into broader mechanical scope (boilers, process piping) is covered under mechanical contractor bonds.
Running Service Routes Across Multiple Texas Cities
This is the normal operating reality for a Texas HVAC company, and it deserves more attention than it gets. A contractor based in Plano might pull permits in Dallas, Richardson, Garland, and Frisco in the same month. The TDLR license and insurance certificate cover all of them -- the state credential is statewide. The municipal layer is not. Every city that requires registration requires its own registration, and every city that requires a bond requires a bond naming that city as obligee.
Practically, that means a multi-city ACR contractor may hold two or three small permit bonds simultaneously. Because each is a $5,000–$10,000 penal sum, the stacked cost stays modest -- three bonds at typical pricing is still usually under $1,000 a year combined -- and a single surety application can support all of them. When you request a Texas contractor bond quote, list every jurisdiction up front so the carrier can write the set together instead of re-underwriting each one.
One renewal-management tip: city bonds renew on their own anniversary dates, not on your TDLR license cycle. Calendar them separately. A lapsed city bond does not affect your state license, but it freezes your permits in that jurisdiction until the replacement bond is filed -- which, mid-summer in Texas, is exactly when you cannot afford a permit freeze.

Texas HVAC Bond FAQs
Does TDLR require a surety bond for a Texas HVAC contractor license?
No. The Texas Department of Licensing and Regulation does not require a surety bond for an Air Conditioning and Refrigeration (ACR) contractor license. Texas Occupations Code Chapter 1302 and the TDLR rule at 16 TAC Section 75.40 require commercial general liability insurance instead: Class A licensees must carry $300,000 per occurrence / $600,000 aggregate, and Class B licensees must carry $100,000 per occurrence / $200,000 aggregate. Any product marketed as a "Texas state HVAC bond" is mislabeled -- the surety bonds Texas HVAC contractors actually buy are city or county permit bonds.
What insurance limits do Class A and Class B ACR contractors need in Texas?
Under 16 TAC Section 75.40, a Class A ACR contractor must maintain commercial general liability insurance of at least $300,000 per occurrence (combined for bodily injury and property damage), $600,000 aggregate, and $300,000 aggregate for products and completed operations. A Class B ACR contractor needs $100,000 per occurrence, $200,000 aggregate, and $100,000 products/completed-operations aggregate. The certificate of insurance is filed with TDLR and must stay active for the license to remain valid. These are insurance requirements, not bond amounts.
Which Texas cities require an HVAC contractor bond?
It varies by city and by the scope of the permit. Dallas requires a $10,000 surety bond under Dallas City Code Chapter 52 for contractors performing work in the public right-of-way (paving, sidewalk, curb, driveway approaches) -- an HVAC contractor only needs it if the job touches right-of-way scope. Houston generally accepts the TDLR-filed insurance certificate for trade permits, so a separate Houston bond is often unnecessary for ACR-licensed contractors. San Antonio relies on the TDLR license plus local registration for mechanical work. Because municipal ordinances change, always confirm the current requirement with the specific city permitting office before bidding.
Do I need a separate bond for each Texas city where I pull permits?
If a city requires a permit bond, yes -- each bond names that specific city as obligee, so a Dallas bond does not satisfy a Fort Worth or Austin requirement. Your TDLR ACR license is valid statewide, and the TDLR insurance certificate travels with it, but municipal registration and bonding are jurisdiction-by-jurisdiction. Contractors running service routes across multiple metro cities commonly hold two or three small permit bonds at once. The good news: these are small-penal-sum bonds, and most carriers will write all of them off a single application.
How much does a municipal HVAC bond cost in Texas?
Texas municipal trade-permit bonds typically carry penal sums in the $5,000 to $10,000 range, and annual premiums generally run $100 to $500 depending on the bond amount, the city form, and your credit profile. A contractor with strong credit on a $10,000 Dallas right-of-way bond is usually at the low end of that range. Unlike the TDLR insurance requirement -- which is a recurring policy premium based on your revenue and operations -- the permit bond is a flat, small annual cost.
What is the difference between a TACLA (Class A) and TACLB (Class B) license?
Class A (license numbers prefixed TACLA) authorizes air conditioning and refrigeration work on systems of any size. Class B (TACLB) restricts the licensee to smaller systems -- cooling systems of 25 tons or less, which covers most residential and light-commercial work. The class you hold drives your insurance floor under 16 TAC Section 75.40: Class A carries the $300K/$600K requirement while Class B carries $100K/$200K. Neither class triggers a state surety bond. Confirm current class definitions and endorsements (environmental air, commercial refrigeration, or combined) on the TDLR ACR program page before applying.
Can I get a Texas city HVAC permit bond with bad credit?
Almost always, yes. Municipal permit bonds in the $5,000-$10,000 range are small enough that specialty surety markets write them down to roughly a 500 FICO without collateral -- the low credit tier simply prices at a higher percentage rate, often 8-15% instead of 1-3%. On a $10,000 bond that is the difference between roughly $100-$300 and $800-$1,500 a year. The TDLR insurance requirement is unaffected by credit; liability insurance underwriting looks at operations and claims history, not FICO.

Verification Methodology
State requirements on this page cite Texas Occupations Code Chapter 1302 (Air Conditioning and Refrigeration Contractors) and 16 TAC §75.40 (TDLR insurance requirements for ACR contractors). Class A limits ($300K/$600K) reflect the published rule. Class B limits ($100K/$200K) are consistent with the Class A floor and TACLB scope restriction; the TDLR rule page was inaccessible at publication -- confirm Class B figures on the TDLR ACR program page before relying on them. The Dallas $10,000 right-of-way bond reflects Dallas City Code Chapter 52 as published May 2026. Municipal bond amounts and scopes change by local ordinance -- always confirm the current penal sum and bond form with the issuing city before purchase. Premium figures are indicative, non-binding ranges from specialty surety markets; final pricing depends on carrier review of the individual application. Bonds are issued by Treasury-listed carriers authorized to transact surety business in Texas.
