Target audience: HVAC contractors in Houston, TX (and Texas metro areas) seeking higher bonding capacity for commercial and public HVAC projects. This guide explains how to strengthen the three pillars surety underwriters evaluate—financial statements, project experience, and professional relationships—and gives concrete steps, examples and cost estimates so you can bid larger jobs with confidence.
Why bonding capacity matters for HVAC contractors
Bonding capacity determines the maximum size and type of projects you can bid on or perform when project owners require bid, performance and payment bonds. Public and large commercial projects in Houston, Dallas and Austin routinely require bonds equal to 50%–100% of the contract value. Without adequate bonding capacity you may be excluded from lucrative HVAC contracts or forced to accept unfavorable subcontractor positions. For typical scenarios where owners require bonds, see When Owners Require Bonds: Typical Scenarios in HVAC Public and Commercial Projects.
Key takeaway: Improving bonding capacity is often the fastest way to scale from small commercial HVAC jobs to multi-million-dollar projects.
The three pillars sureties evaluate
- Financial strength and accounting accuracy (most influential)
- Relevant project experience and performance history
- Relationships with surety companies, brokers and banks
Below we break down practical actions and measurable targets for each pillar.
H2: Pillar 1 — Financial Statements (clean, credible, and current)
Underwriters expect reliable, verifiable financial statements. Poor or unaudited books are the most common reason for capacity limits.
H3: What underwriters look for
- Net worth / working capital: Positive and growing net worth. For many underwriters, a net worth of at least $100,000–$500,000 is a baseline for small-to-mid bonding; larger public work often requires net worth in the mid-six-figures or higher.
- Current ratio (current assets ÷ current liabilities): Preferably ≥1.5.
- Debt-to-equity: Lower ratios are better; targeted <2.0 for comfortable capacity.
- Cash flow & backlog: Proof of liquidity to carry projects (lines of credit, cash reserves).
- Historical profitability: Stable profits over the last 2–3 years.
H3: Actions to improve financial presentation
- Move to CPA-reviewed or audited financials (full GAAP statements if possible).
- Prepare a clear work-in-progress (WIP) report showing percent complete, retainage, billings and cost-to-complete.
- Separate business and personal finances; pay owners’ draws as documented distributions.
- Establish a $100k–$250k working capital reserve where feasible.
- Maintain a clean aging receivables report and minimize overdue payables.
H3: Typical underwriting thresholds and bond cost examples
| Contractor credit/profile | Typical bond rate (performance/payment) | Sample cost on $1,000,000 bond |
|---|---|---|
| A-credit (700+ FICO, strong financials) | 0.5% – 1.5% | $5,000 – $15,000 |
| B-credit (600–699, adequate statements) | 1.5% – 3% | $15,000 – $30,000 |
| C-credit (below 600, weaker finances) | 3% – 5%+ | $30,000 – $50,000+ |
Example: A well-qualified HVAC contractor bidding a $1,000,000 performance bond at a 1% premium would typically pay a one-time premium of $10,000 (premium structures vary by surety and contract length). Bid bonds often cost 0.5%–1% or a flat fee for small amounts.

H2: Pillar 2 — Experience (verifiable, relevant, and recent)
H3: What counts as strong experience
- Completed HVAC projects of similar scope, technology (e.g., rooftop units, VRF systems, chilled water plants), and contract size.
- Positive owner and general contractor references showing timely completion and adherence to budgets.
- Steady backlog indicating demand and capacity utilization.
H3: How to package experience for underwriters
- Provide a concise project resume list (last 3–5 years) with:
- Project name, owner/GC contact, contract value, completion date, scope, and % self-performed.
- Include change order history and explanations for any overruns.
- Highlight safety records, bonding claims history (if none, say “no claims”), and performance ratings.
H3: Practical targets (Houston example)
- Aim for at least 3–5 projects in the $200k–$1M range completed in the last 3 years to support requests for $1M+ bonding lines in the Houston market.
- For public bids in Harris County or Houston ISD, having prior municipal or school district experience materially increases approval odds.

H2: Pillar 3 — Relationships (surety, broker, bank)
H3: Why relationships matter
Long-term relationships with a surety or experienced broker lead to better pricing, faster approvals and access to larger bonding lines. Banks that understand construction lending will support liquidity needs.
H3: Who to cultivate
- National surety carriers active in construction: Liberty Mutual Surety, Travelers, CNA Surety — they underwrite many HVAC firms in Texas.
- Liberty Mutual Surety: https://business.libertymutualgroup.com/insurance/surety
- Travelers Surety: https://www.travelers.com/business-insurance/insurance/surety-bonds
- CNA Surety: https://www.cna.com/web/guest/business-insurance/surety
- Local surety brokers with HVAC construction expertise (Houston-based brokers often know municipal requirements and underwriter preferences).
- Commercial lenders and local community banks that will provide lines of credit or bonding collateral.
H3: Negotiation & pricing tips
- Shop through multiple brokers to get competing surety appetite—premiums can vary materially.
- Leverage a portfolio approach with one carrier for bid/performance/payment lines to get volume discounts.
- Offer collateral sparingly; underwriters prefer strong financials over pledged assets. If collateral is required, secure it via negotiable LOCs from reputable banks.

H2: Actionable 60–90 day plan (Houston-focused)
- Week 1–2: Order CPA-reviewed financials (last 2 fiscal years + YTD) and prepare WIP schedule.
- Week 3–4: Assemble project resume with 3–5 comparable HVAC projects (contact GC/owner references).
- Month 2: Meet two surety brokers in Houston; request indicative quotes from at least 2 carriers (Travelers, Liberty Mutual, CNA).
- Month 2–3: Clean up receivables, reduce short-term debt, build $25k–100k cash reserve for liquidity.
- Month 3: Apply for an open line of credit or letter of credit with your local bank for contingency support.
Checklist:
- CPA-reviewed financial statements
- WIP & backlog report
- Project resume + references
- Broker introductions + at least two carrier quotes
- Bank LOC or operating line of credit

Final notes and realistic expectations
- Costs and timescales: Expect a one-time premium on performance bonds equal to the rate × bond amount (e.g., 1% of $1M = $10,000). Larger or long-duration projects can increase effective costs. Improving financials and experience is a medium-term effort (3–12 months) but yields sustainable increases in bonding capacity.
- Local nuance: Houston’s market values municipal experience, safety programs, and relationships with local GCs. Tailor your package to local owners and agencies when pursuing public work.
- When you need help: Work with an experienced surety broker who understands HVAC contracts and Houston public bid requirements to speed approvals and improve pricing.
