HVAC Contractor Working Capital in Texas

Who's Actually Borrowing: The Texas HVAC Contractor Profile

Most of the Texas HVAC operators we work with aren't running massive commercial shops — they're 3-to-12-person crews doing residential replacements in the DFW Metroplex, new-construction installs in the San Antonio and Austin growth corridors, and light commercial retrofits in Houston's dense office and strip-mall inventory. The typical deal we see is somewhere between $50,000 and $300,000 in working capital, sized to cover a seasonal surge or a string of large jobs that all land at once.

The buyer profile skews toward owner-operators who've been in the trade for years, built a customer base, and now find themselves cash-tight not because the business is failing but because it's growing faster than their receivables cycle can support. A contractor landing three new-construction tract-home contracts in Frisco or Katy simultaneously needs to pay for equipment, refrigerant, and labor before the builder pays the draw — and those gaps can run $30,000 to $80,000 per project without breaking a sweat.

Why Texas Creates Its Own Cash-Flow Physics

Texas heat is not a metaphor. When a heat dome parks over the state in July and August — and it does, reliably, with days above 105°F across Central Texas — residential call volume spikes overnight. That's good for revenue and brutal for cash. You're buying R-410A and R-32 refrigerant in bulk, pulling permits in three counties simultaneously, and paying overtime to keep crews moving. The Texas Department of Licensing and Regulation (TDLR) requires HVAC contractors to carry active state licensure and pull permits for virtually all equipment replacements, which means permit fees and inspection timelines are a real line item, not a footnote.

The commercial side adds another layer. Houston and Dallas have significant Class B and C office inventory undergoing energy-efficiency retrofits — projects driven partly by Texas's deregulated energy market, where building owners have direct incentive to cut consumption. Those retrofit contracts often run 60-to-90-day payment terms, and the gap between mobilization and first draw can easily exceed $100,000 on a mid-size project.

Winter storm exposure is a secondary driver. Post-Uri, Texas property managers and homeowners have been faster to authorize full system replacements rather than patch repairs, which means bigger average tickets but also longer materials lead times and upfront equipment deposits that arrive weeks before the job completes.

How Working Capital Actually Gets Structured for Texas HVAC Shops

For most Texas HVAC contractors, working capital comes in one of three practical forms: an unsecured term loan, a revolving business line of credit, or — for operators who need speed over cost — a revenue-based advance.

The term loan is the most common fit for a defined cash need: buying a van, pre-purchasing equipment for a summer backlog, or bridging a 45-day payment gap on a commercial retrofit. SBA 7(a) loans run 8.5–11% APR with terms up to 10 years and a maximum of $5,000,000 — solid if you have 30–45 days to wait on approval and the documentation is clean. Origination fees typically run 1–3% of the loan amount.

A revolving line of credit makes more sense for operators with lumpy but recurring cash needs — pull when you need it, pay it down between jobs, avoid paying interest on idle funds. Lines are generally sized at 10–20% of annual revenue for well-qualified Texas applicants.

Revenue-based advances fund in 24–72 hours and require less documentation, but the cost is real — APR equivalents of 80–150% are common. We only recommend that path when a time-sensitive opportunity (a builder contract, an emergency commercial job) makes the math work despite the cost. Use it surgically, not as a substitute for proper capitalization.

The money itself goes toward refrigerant inventory, van stock, permit fees, subcontractor labor, equipment deposits with distributors like Johnstone or Wesco, and payroll during the gap between job completion and client payment.

Eligibility and What to Pull Together Before You Apply

For a conventional working capital term loan or SBA 7(a), lenders want to see at least 24 months in business and annual revenue of $150,000–$250,000 minimum. A personal FICO above 640 clears most SBA floors; scores in the 700+ range open up the best rate tiers. Fair-credit borrowers in the 620–679 range can still qualify but should expect rates 2–4 percentage points higher than top-tier pricing. Lenders also want your total monthly debt service to stay under 45–50% of gross monthly revenue, and a debt service coverage ratio of at least 1.25x.

For the application package, pull together 12 months of business bank statements, your two most recent business tax returns, a current profit-and-loss statement, and your TDLR HVAC contractor license certificate. If you're applying as an LLC or corporation, have your Texas Secretary of State formation documents and EIN confirmation ready. Commercial jobs will benefit from showing executed contracts or letters of intent — underwriters in Texas respond well to signed scope-of-work documents because they demonstrate committed revenue, not just projected revenue.

One thing worth doing before you submit anywhere: pull your own business credit report. Roughly 1 in 5 credit reports contain errors, and a misreported delinquency can knock your rate up or kill an approval entirely. Fix it before a lender sees it, not after.
