HVAC Business Acquisition Financing in 2026: SBA vs Seller Note vs Investor Equity (Worked Example)
by Raises.com
HVAC business acquisition financing in 2026 usually means three sources working together: an SBA 7(a) loan for most of the price, a seller note that can sit on standby to reduce your equity injection, and investor equity through an SPV for whatever cash you do not have. On a $2.5 million purchase that combination can bring the buyer's own cash down to a fraction of the price while keeping debt service coverage comfortably above what lenders require.
The worked example: a $2.5 million HVAC contractor
Illustrative numbers, rounded, to show the mechanics. Actual rates and terms depend on the lender, the SBA's current rate caps and the deal.
| Line | Amount | Note |
|---|---|---|
| Purchase price | $2,500,000 | About 4x EBITDA of $600,000 |
| SBA 7(a) loan | $1,900,000 | 10-year term at an illustrative 10.5% variable rate |
| Seller note | $375,000 | 7% interest, half of it on full standby to count toward injection |
| Equity injection (10% of project) | $250,000 | $125,000 may be the standby seller note; $125,000 cash from buyer or SPV investors |
| Annual SBA debt service | About $308,000 | Principal and interest on $1.9M over 10 years at 10.5% |
| Annual seller-note interest | About $26,000 | Interest-only during the standby period |
| Total annual debt service | About $334,000 | |
| Debt service coverage ratio | About 1.8x | $600,000 EBITDA divided by $334,000, before the buyer's salary and capex |
After a market salary for the buyer and replacement capex for the fleet, coverage lands closer to 1.4x, still above the 1.25x floor most lenders use. That headroom is what survives a bad summer or a technician walking out with accounts.
The three sources compared
| SBA 7(a) | Seller note | Investor equity (SPV) | |
|---|---|---|---|
| Share of a typical deal | 60 to 80% | 10 to 25% | 10 to 30% |
| Cost | Prime plus a capped spread | Often 5 to 8% | Preferred return plus a profit share |
| Repayment | Monthly, 10 years | Negotiated; standby possible | From distributions and exit |
| Guarantee | Personal, 20%+ owners | Usually secured behind the bank | None, but investors expect you to guarantee the senior loan |
| Control | Covenants | Seller consent rights are rare | You remain manager; investors hold economic rights |
| Speed | 60 to 120 days | Set at LOI | 30 to 90 days once documents exist |
| What it requires | Injection, DSCR, experience | A seller who believes in the business | PPM, subscription agreement, operating agreement, model, data room |
HVAC-specific items that move the financing
- Maintenance-agreement revenue. The more of EBITDA that comes from recurring agreements, the better the lender terms. Break it out in the model.
- Seasonal working capital. Inventory builds before summer; a working-capital line approved at close prevents the first cash crunch.
- Fleet condition. Old trucks are capex the lender will haircut from cash flow. Finance the fleet separately when it makes the acquisition loan smaller.
- The refrigerant transition. Inventory of legacy R-410A equipment and the training cost for lower-GWP refrigerants belong in diligence.
- License continuity. The lender will ask who the qualifying license holder is after close. Answer it in the transition agreement.
What this looks like on a real close
In July 2026 a Raises.com client, a Texas construction operator named Cody Sechelski, closed the inaugural acquisition of his services roll-up: a profitable Texas HVAC contractor in the roughly $2.4 million range. The stack was an institutional senior credit facility, junior debt, a seller note, seller rollover equity and a structured equity gap, closed with minimal sponsor cash equity. He booked his first call in October 2025, so the active engagement ran about seven months, including a funding tournament across multiple capital firms and a final lender that quoted three weeks and took two months. The close was covered by Yahoo Finance, AP News, Morningstar and The Globe and Mail, and he tells the whole story on the podcast.

Frequently asked questions
What DSCR do lenders want on an HVAC acquisition?
A minimum of about 1.25x after the buyer's salary is the common floor for SBA lenders; more headroom is expected when revenue is seasonal or customer concentration is high.
Can the seller note count toward my SBA equity injection?
Yes, up to half of the required injection, if the note is on full standby for the life of the SBA loan under the current operating procedures. The rest must be cash from you or from approved investors.
Should I use investor equity or a bigger seller note?
Use both. The seller note is cheaper, but sellers have a limit. Investor equity through an SPV fills what the seller will not carry and costs upside rather than monthly cash.
How is an HVAC business valued for financing?
On a multiple of seller's discretionary earnings for owner-operated shops and EBITDA for larger companies, adjusted for recurring revenue, technician count, fleet and owner dependence. The lender then tests whether the price is supported by cash flow, not by the multiple.
What did the Texas close use?
An institutional senior credit facility, junior debt, a seller note, seller rollover equity and a structured equity gap, closed with minimal sponsor cash equity on a deal in the roughly $2.4 million range. It is described in the press release.
