What SDE Multiple Do HVAC Businesses Sell For in 2026?

HVAC businesses in 2026 are selling for 3.0x-5.0x SDE, with most transactions landing in the 3.5x-4.2x range. The high end — 4.5x to 5.0x SDE — is reserved for businesses with significant recurring maintenance revenue, multiple technicians, and limited owner dependency. Installation-heavy businesses without service agreements typically land at 2.5x-3.5x SDE.

Size matters. PE-backed buyers like Apex Service Partners and Wrench Group have minimum deal thresholds around $800K-$1M in SDE. Below that, the buyer pool shrinks and multiples compress accordingly.

Key Data: 3.0x-5.0x SDE typical range | 3.5x-4.2x average transaction | 4.5x-5.0x for maintenance-heavy businesses

What Drives HVAC SDE Multiples Higher?

Recurring maintenance agreements are the single biggest driver of premium SDE multiples in HVAC. A business with 30%-40% of revenue in maintenance contracts gives buyers predictable, retained revenue — and they pay for that predictability. I've seen businesses with identical SDE trade at a 1.0x difference in multiple based on revenue mix alone.

Beyond maintenance revenue, the factors that push multiples toward 4.5x-5.0x are: technician depth, a service manager who runs operations independently, geographic concentration in high-income areas, and three years of clean financials. Buyers also evaluate your Google reviews and customer retention. A business with 500 or more active maintenance customers and low churn tells a compelling story to PE-backed acquirers.

How Does Business Size Affect HVAC SDE Multiples?

Bigger HVAC businesses consistently trade at higher multiples because of buyer competition. At $500K-$800K in SDE, you're working with individual buyers and smaller regional platforms. At $1M or more in SDE, PE-backed institutional buyers step in aggressively, creating competitive dynamics that drive prices up. Businesses in the $2M-$5M revenue range average around 3.65x SDE, while those in the $5M-$10M range average 4.18x SDE — a meaningful difference driven almost entirely by buyer competition.

"The multiple gap between a maintenance-heavy HVAC business and an installation-only business is real and persistent. When I'm running a competitive process, recurring revenue is the first thing every buyer asks about. It's the fastest way to move your valuation from 3.5x to 4.5x."

How Does Business Size Affect HVAC SDE Multiples?
Bigger HVAC businesses consistently trade at higher SDE multiples because of buyer competition. At $500K-$800K in SDE, you're working primarily with individual buyers and smaller regional platforms — a real market, but a narrower one. At $1M or more in SDE, PE-backed institutional buyers step in aggressively, creating competitive dynamics that push prices up. Research shows businesses in the $2M-$5M revenue range average around 3.65x SDE, while those in the $5M-$10M revenue range average 4.18x SDE. That's a 14% difference in multiple driven almost entirely by buyer competition at higher revenue levels. The practical implication: if you're sitting at $700K in SDE, adding recurring maintenance contracts to reach $900K or more changes your buyer pool and your multiple meaningfully.
