The short answer: Most HVAC businesses sell for $300,000, $1.3M, with a median asking price around $648,500 and climbing. Price = SDE × the ~2.80× multiple. With an SBA 7(a) loan you need a 10% equity injection, about $65K on a $650K shop, and up to half can be a seller note on standby, so your own cash can be as low as ~$32,500 plus closing costs and working capital. Run it in the valuation calculator.
What HVAC businesses actually cost
Price scales with earnings, not trucks. Here's the 2026 range by size:
| Business | Revenue | SDE | Typical price |
|---|---|---|---|
| Small owner-operator (1 to 2 trucks) | $300K, $600K | $80K, $150K | $220K, $430K |
| Established shop (median deal) | ~$1.1M | ~$242K | ~$648K |
| Larger service company | $2M, $5M | $400K, $900K | $1.3M, $3.3M+ |
Median HVAC sale prices rose roughly 23% from 2021 to 2025 (about $650K toward $800K) as buyer demand, including private equity, pushed multiples up. The single biggest price driver within a size band is the service-vs-install mix and the maintenance-agreement book.
How the price is set: the multiple
Main Street HVAC deals price off SDE × a multiple. The median multiple is ~2.80×, ranging from about 1.7× for owner-heavy, install-dependent shops to 3.7× for service-heavy, systematized ones.
| Multiple | Implied price | When it applies |
|---|---|---|
| 1.7× (low) | $411,000 | Install-heavy, owner-dependent, messy books |
| 2.8× (median) | $678,000 | Typical mixed service/install shop |
| 3.7× (high) | $895,000 | Service-heavy, strong agreement book, runs on a crew |
Same earnings, a $484,000 swing in price, driven entirely by revenue quality and owner-dependence. See the live figure on HVAC multiples and learn the mechanics in valuation.
You don't negotiate the price. You negotiate the multiple, and you earn a lower one by fixing the things that scare a lender.
The down payment and the full capital stack
Under SBA 7(a) rules, a change of ownership needs a minimum 10% equity injection, and up to half of that can be a seller note on full standby. Here's the worked stack on a $650,000 HVAC business:
| Source / use | Amount | % of price |
|---|---|---|
| SBA 7(a) bank loan | $585,000 | 90% |
| Your cash injection | $32,500 | 5% |
| Seller note (full standby) | $32,500 | 5% |
| Purchase price | $650,000 | 100% |
| + Est. closing costs & fees (financed) | ~$25,000 | |
| + Working-capital reserve | $30K, $50K |
So the honest "cash to close" on this deal is your ~$32,500 injection plus a working-capital cushion for the slow shoulder seasons, not the full $650K. The loan is then sized so cash flow covers debt at a DSCR of ~1.15×, 1.25×.
Does this deal cash-flow?
At $242K SDE and ~$90K annual debt service, DSCR is about 2.7× before any owner salary, comfortably bankable. After reserving a $110K market salary, it's still ~1.5×. Verify in the DSCR guide.
Costs buyers forget
- SBA guarantee & packaging fees, a percentage of the guaranteed loan amount, usually financed.
- Legal & closing, purchase agreement, entity setup, lien searches.
- Quality-of-earnings / valuation review, money well spent to verify the add-backs behind that SDE.
- License continuity, retaining the seller's qualifier or securing your own (see the playbook).
- Fleet & equipment capex, aging trucks are a near-term cash need, not part of the price.
- Working capital, the shoulder-season buffer that keeps a profitable shop from going broke.

Frequently asked questions
Most sell between $300K and $1.3M, with a median asking price near $648,000. Price is SDE × the ~2.80× multiple, so a shop with $240K of SDE prices around $670K. See HVAC multiples.
An SBA 7(a) loan needs a 10% equity injection, $65K on a $650K shop, and up to half can be a seller note on full standby, so your own cash can be as little as ~$32,500 plus closing costs and working capital.
Not fully, SBA requires a minimum 10% injection. But up to half can be a standby seller note, cutting your own cash to ~5%. True zero-down deals are rare and usually rely on seller financing outside SBA.
Budget for SBA fees, legal/closing, a quality-of-earnings review, and working capital for the slow seasons. On a $650K deal these add tens of thousands, much of which can be rolled into the loan.
