Why HVAC trades above most trades
HVAC clears the small-business median because demand is non-discretionary and weather-driven, when a compressor dies in August, price sensitivity vanishes, and because equipment replacements run into five figures. That combination of urgency and ticket size is exactly what buyers and lenders like. It is also why heating and air has become the poster child for private-equity roll-ups: an independent shop that trades near 2.9× SDE on the open market can be worth 8× EBITDA or more once it is folded into a regional platform, purely from the multiple arbitrage.
What buyers check first
The diligence conversation on an HVAC deal moves fast to a few line items:
- Service-agreement count and renewal rate. Maintenance plans are the recurring-revenue proxy; shops with 30%+ of revenue under agreement command the top of the range.
- Install vs. service revenue split. Heavy new-construction exposure is cyclical and gets discounted; retrofit and replacement work is stickier.
- Technician retention and licensing. A buyer is inheriting labor, not just customers, a master license that transfers and techs who stay are worth real multiple.
- Owner dependence. If the seller is the top diagnostician and the biggest sales rep, the multiple compresses toward a job, not an asset.
In HVAC, you are not buying a truck and a name, you are buying a book of maintenance agreements and the techs who service them.
Deal size and structure
Most Main Street HVAC transactions are SBA-financed asset sales in the low-to-mid six figures of SDE, with 80 to 90% cash at close and a modest seller note. As companies cross roughly $1M of EBITDA, the buyer pool shifts from individuals to consolidators (national platforms and PE add-ons), the metric shifts from SDE to EBITDA, and part of the consideration often becomes rollover equity and an earnout tied to the maintenance base.
Buyer's move
Ask for the maintenance-agreement schedule before anything else. The count, price, and renewal rate of those plans tell you more about the real multiple than the P&L headline does.

HVAC valuation multiples, FAQ
A typical owner-operated HVAC company sold at roughly 2.8× SDE in 2026, with most Main Street deals between 2.0× and 3.5× SDE. Larger, management-run companies are quoted on EBITDA and can reach 4×, 8× when a private-equity buyer is involved.
Roll-up arbitrage. A single shop trades near 2.9× SDE, but once it is combined with others into a platform, overhead is shared and the assembled company can exit at a much higher EBITDA multiple. The PE buyer captures the spread, so it can afford to quote 4×, 8× EBITDA for the same business an individual would buy at ~3× SDE.
Recurring maintenance-agreement revenue, low owner dependence, retained and licensed technicians, and a replacement/retrofit mix rather than new construction. Each reduces the buyer’s risk, and every turn of risk removed is worth a fraction of a turn on the multiple.
