HVAC EBITDA Multiple Reference Table (2025)

|---|---|---|---|
| Under $500K | 2.5x–4x | Broker/Searcher | Clean books, owner willing to stay 1–2 years |

| $1M–$2M | 4.5x–6x | PE Add-On/Platform | GM in place, 40%+ recurring |
| $2M–$4M | 5.5x–7.5x | PE Platform | Owner-independent ops, software dispatch |

These are cleared multiples from 2024–2025 transactions — not asking prices. Actual multiples vary based on the 6 factors below.
What Moves Your HVAC Multiple
Same EBITDA, very different multiples — here's what PE buyers actually underwrite.
Recurring Contract Revenue
+0.5x to +1.5xEvery 10% increase in maintenance agreement revenue as a % of total adds approximately 0.3x–0.5x to your multiple. At 60%+ recurring, you unlock the platform tier.
EBITDA Size
+0.5x to +2xPE firms pay a "size premium." A $3M EBITDA business commands 1.5x–2x more than a $500K EBITDA business even if the margins are identical. Scale matters more than efficiency.
Owner-Independence
+0.5x to +1xCan the business operate at 90%+ capacity if you leave for 3 months? If no, PE prices in a transition discount. A GM with 2+ years of tenure and documented SOPs adds 0.5x–1x.
Financial Clarity
+0.5x to +0.75xClean, accountant-prepared financials (ideally reviewed/compiled) with add-backs clearly documented. PE's QoE firm will find the truth anyway — sellers who present it first get better prices.
Software & Systems
+0.25x to +0.5xServiceTitan, Housecall Pro, or similar dispatch software signals scalability. PE add-on buyers plug your business into their existing tech stack — easier integration = higher multiple.
Growth Trajectory
+0.25x to +0.75x15%+ revenue growth over 2–3 years compounds the multiple. PE underwrites forward EBITDA, not trailing. A business growing fast gets a premium for the EBITDA they'll earn in year 2 of PE ownership.

EBITDA vs. SDE: Which Multiple Applies to You?
SDE
Seller's Discretionary Earnings- Used for:Businesses under $1M in revenue or owner-operated
- Who uses it:Business brokers, searchers, small-business buyers
- Multiple range:2x–4x
- What it includes:EBITDA + owner salary + personal expenses
If your broker is quoting SDE multiples, you're probably not in PE territory yet.
EBITDA
PE Standard- Used for:Businesses with $500K+ in EBITDA and management in place
- Who uses it:Private equity, strategic acquirers, family offices
- Multiple range:4x–10x+
- What it includes:Earnings before interest, taxes, depreciation, amortization
PE always uses EBITDA. Maximizing EBITDA (not revenue) is the game.
Most HVAC owners trying to sell to PE have businesses in the $1M–$5M revenue range. At that size, you're usually in EBITDA territory — but the line isn't always clean. Our calculator handles both.
HVAC EBITDA Multiple FAQ
What EBITDA multiple do PE firms pay for HVAC companies?
PE firms currently pay 4x–7x EBITDA for most HVAC businesses, with elite platforms (60%+ maintenance agreements, $2M+ EBITDA, owner-independent) reaching 8x–10x+. The average cleared multiple in 2024–2025 for mid-market HVAC add-on deals was approximately 5x–5.5x.
How is EBITDA calculated for an HVAC business?
EBITDA = Net Income + Interest + Taxes + Depreciation + Amortization. For HVAC businesses, PE buyers typically add back owner salary above market rate, personal vehicle expenses, one-time costs, and non-recurring items. This "adjusted EBITDA" or "normalized EBITDA" is the actual basis for the multiple — and it's almost always higher than what appears on your tax return.
What EBITDA does my HVAC business need for PE interest?
Most PE firms have a minimum threshold of $500K–$1M in EBITDA before they'll engage. Below $500K, you're in broker/searcher territory with SDE multiples (2x–4x). At $1M+ EBITDA, you become a viable PE add-on target. At $2M+, you can run a competitive auction with multiple buyers.
