What's a Fair Multiple for an HVAC Business?
HVAC is one of the most sought-after trades businesses to buy — essential, high-ticket, and full of recurring revenue if it's run well. The multiple you should pay depends almost entirely on how transferable and recurring the earnings are.
The fair range
| Quality | Multiple (× SDE) | Profile |
|---|---|---|
| Low | 2.5× | Owner is lead tech; install-heavy; no contracts |
| Typical | 3.25× | Some recurring work; small stable crew |
| High | 4.5× | Strong maintenance agreements; manager in place |
What pushes a deal to the top of the range
Recurring maintenance agreements.A book of seasonal tune-up contracts is gold — it's predictable revenue that funnels into repair and replacement work. A crew that isn't the owner. If trained technicians and a dispatcher run the day-to-day, the business survives the transition. Service/repair mix over new construction. Service margins are higher and less cyclical than install-only revenue tied to new builds.
What drags it down
Owner dependence, customer concentration (a few large commercial accounts), unlicensed or thin staffing, and lumpy install-driven revenue all justify a lower multiple. Deferred truck and equipment maintenance is a hidden capex liability — factor it in.
Structure it with seller financing
Because so much HVAC value walks out the door with the owner, a seller note aligns incentives: it keeps the seller invested in a clean handoff of customers and crew. Don't just negotiate price — negotiate structure.
