The $3M Gap
Same HVAC business. Owner-managed vs. PE-ready. $5.25M vs. $8.25M.
The difference isn't luck — it's knowing your number and what drives it. $1.5M EBITDA × 3.5x (owner-managed, no systems) = $5.25M. Same EBITDA × 5.5x (PE-ready, recurring revenue, ServiceTitan 24+ months) = $8.25M.
Most HVAC owners find out what their business is worth the same way: someone makes them an offer. By then it's too late to negotiate from a position of knowledge. Brokers charge 4%–8% of transaction value to run the math — on a $7M deal, that's $280K–$560K before you've done a thing.
Here's the reality: you can build a solid working estimate yourself in an afternoon. PE firms use a specific framework — EBITDA × multiple, adjusted for five business quality factors — and that framework is not proprietary. What follows is that framework, step by step, with the math.
Why HVAC Valuation Is Different from Other Businesses
HVAC isn't valued like a restaurant, retail store, or professional services firm. It sits at the intersection of three things PE buyers pay a premium for: predictable service cash flows, a fragmented market ripe for consolidation, and recession-resistant demand. People don't skip HVAC repairs when the economy dips.
Three reasons PE pays more for HVAC than most service businesses:
Predictable cash flows
Maintenance contracts create a revenue base that renews annually. PE models love recurring revenue — it de-risks the acquisition thesis and justifies a higher multiple.
Fragmented consolidation market
The HVAC industry is still predominantly owner-operated. PE roll-ups are building platforms by acquiring 10–30 businesses, creating scale advantages. Fragmentation is the opportunity — and HVAC is still early in that cycle.
Recession-resistant demand
HVAC is not discretionary. A furnace that fails in January gets replaced regardless of the economy. That defensibility is worth something in PE underwriting.
What PE actually buys: EBITDA × multiple. Not revenue. Not gross profit. For businesses above $500K EBITDA, PE uses EBITDA multiples — not SDE (Seller's Discretionary Earnings). Below $500K EBITDA, SDE multiples of 2.5x–4x apply. Mid-market HVAC ($1M–$3M EBITDA) is firmly in EBITDA territory. If you're in the sub-$500K range, read the SDE vs. EBITDA guide first.

Calculate My Valuation →Step 1 — Calculate Your EBITDA (The Right Way)
Start with your tax returns for the last three years. PE always requests three years — a single-year number isn't enough to establish a trend or identify one-time anomalies.
The Adjusted EBITDA calculation:
Adjusted EBITDA Bridge
Net income (from tax return)
Starting point — Schedule C or corporate return
+ Depreciation & amortization
Non-cash charges — add back to gross EBITDA
+ Interest expense
PE uses unlevered EBITDA — add back debt service
+ Taxes
Pre-tax earnings is the basis for PE valuation
+ Owner addbacks
Above-market comp, personal expenses, one-time costs — be conservative
− One-time revenue spikes
COVID stimulus work, emergency storm jobs, non-recurring projects
= Adjusted EBITDA ← This is the number PE uses
If your Adjusted EBITDA comes out below $300K, you're likely in SDE territory. See the SDE vs. EBITDA post for the right framework to apply.

The OffRamp calculator applies these adjustments automatically based on your inputs — and gives you a PE Readiness Score alongside your estimated range.
Use the calculator to apply these adjustments automaticallyStep 2 — Determine Your Base Multiple Range
Once you have your Adjusted EBITDA, your EBITDA size determines your entry-point multiple range. Here's the market as of 2026:
HVAC EBITDA Multiple Tiers — 2026
| EBITDA Range | Multiple Range | Typical Buyer |
|---|---|---|
| Below $500K | 2.5x–4x SDE | Individual buyers, search funds |
| $500K–$1M | 3.5x–4.5x | Lower roll-ups, regional PE |
| $1M–$2M | 4x–5.5x | Mid-market PE, roll-ups |
| $2M+ | 5x–7x+ | Platform PE, institutional |
These are entry points, not final numbers. The PE Readiness Score is what moves you within (or above) your tier. A $1.5M EBITDA business at 4.0x gets $6M. The same business at 5.5x gets $8.25M. The factors below determine where in the range you land.
For businesses approaching the $2M+ tier that may qualify for platform pricing, see the detailed breakdown of what PE firms look for in an HVAC platform acquisition.
Step 3 — Apply PE Readiness Adjustments (The Part Brokers Charge For)
This is where the real work is — and where most owners lose money by not understanding it. Your base multiple is a floor, not a price. Five adjustment factors move you up or down from that floor, and understanding each one before any buyer conversation is what separates a well-prepared seller from one who accepts whatever number they're offered.
1. Recurring Revenue
0 to +1.0x2. Owner Independence
0 to +1.0x3. Clean Financials
0 to +0.5x4. Software Systems
0 to +0.5x5. Growth Trajectory
0 to +1.0xSum the adjustments and apply them to your base multiple. The result is your estimated valuation range. A $1.5M EBITDA business at base 4.0x = $6M. Add +1.0x for recurring revenue and +0.5x for systems = 5.5x = $8.25M. That's the $3M gap the callout is pointing at.

Run your PE Readiness Score freeStep 4 — Stress-Test Your Number
You have a working estimate. Before you anchor on it, run it through three stress tests PE will run themselves.
QoE Haircut — Build in 5%–10%
PE firms hire a Quality of Earnings (QoE) firm post-LOI to audit your Adjusted EBITDA. They will find and challenge every addback. A business with $1.5M stated Adjusted EBITDA might land at $1.35M–$1.425M after QoE. Build that haircut into your working range so you aren't surprised by a retrade.
Customer Concentration — the 15% Rule
If any single customer accounts for more than 15% of your revenue, expect a meaningful discount. PE buyers model the risk of losing that customer post-close. At 25%+ concentration, the discount is significant — sometimes 0.5x–1.0x off the multiple. If you have a large commercial or property management account that dominates your revenue, document their contract depth and tenure.
The “Seller Day 1” Question
What happens to the business the day you stop showing up? If the answer is “nothing — the GM runs it and the phones keep ringing,” you get full value. If the answer is “calls stop coming in because every relationship runs through my phone,” expect a discount and a meaningful earnout component in your deal structure.
Final Range Formula
(Adjusted EBITDA × Base Multiple) + Readiness Adjustments − QoE Haircut
= Estimated Enterprise Value Range
What a Broker Actually Does for That 4%–8% Fee
You can do the math yourself. What you can't do yourself — at least not efficiently — is everything else a broker does. Here's where brokers actually earn their fee:
Controlled auction — creates competition among 8–15 buyers
A market price requires multiple buyers competing simultaneously. One buyer giving you a number isn't a market price. A broker's single biggest value add is creating the competitive pressure that forces every buyer to submit their best number — not their opening number.
CIM preparation — makes your business look better on paper
The Confidential Information Memorandum (CIM) is the 20–40 page sell-side document PE firms use to underwrite your deal. It frames your business the way PE thinks about acquisitions. A well-prepared CIM pre-answers diligence questions. A missing CIM leaves buyers filling in gaps with conservative assumptions.
Retrade protection — PE firms try to renegotiate after LOI
Retrades — price cuts after the LOI based on diligence findings — are common in PE transactions. An advisor's relationship with buyers creates accountability. PE firms that retrade without justification pay a reputational price with advisors who run future deal flow.
Data room management — full-time job for 4–6 months
Managing the virtual data room, fielding simultaneous information requests from 3–5 buyers, and coordinating QoE responses is a full-time job. Advisors handle this so you can keep running your business during the sale process.

How do you calculate the value of an HVAC business?
Calculate your Adjusted EBITDA (net income + D&A + interest + taxes + owner addbacks − one-time items), then multiply by your base multiple (3.5x–6x depending on EBITDA size and buyer type). Apply PE Readiness adjustments for recurring revenue, owner independence, clean financials, software systems, and growth trajectory to arrive at your estimated range.
What EBITDA multiple do HVAC businesses sell for?
Most HVAC businesses with $1M–$2M EBITDA sell for 4x–5.5x EBITDA. PE-ready businesses with strong recurring revenue, a documented management team, and 24+ months of ServiceTitan data can reach 5.5x–6.5x. Below $500K EBITDA, SDE multiples of 2.5x–4x are more common.
Do I need a broker to value my HVAC business?
No. You can calculate a working estimate yourself using the EBITDA × multiple framework in this guide. A broker earns their 4%–8% fee primarily through the controlled auction process — creating competition among buyers — not the valuation math. Know your number first, then decide whether to hire a broker.
What is the difference between SDE and EBITDA for HVAC valuation?
SDE (Seller's Discretionary Earnings) includes the owner's salary and benefits and is used for smaller businesses (below $500K EBITDA). EBITDA is standard for mid-market HVAC businesses ($500K+) that PE firms target. Using SDE multiples on a PE-eligible business will significantly understate your value.
