Crossing the $5M EBITDA Line Can Re-Rate Your Whole Multiple

Two companies, same EBITDA, very different price

Both do $5M of EBITDA. One sells at 7x for $35M. The other sells at 11x for $55M. Same trade, same region, same number on the bottom line.

The $20M difference is not a negotiating outcome. It is the answer to one question a buyer settles early: how much of that $5M arrives again next year without anyone winning it a second time.

The three bands, and where the lines actually fall

For HVAC, the published ranges are these. We do not measure transaction multiples and do not publish any of our own: every band below is externally sourced. The primary source is Capstone Partners' HVAC Services Sector M&A Update, corroborated by other published multiple analyses, and you can check it. What we contribute is the other half, the operating data that decides where inside a published range a specific company lands.

Note the overlap between the first two. That is not sloppiness in the data, it is the honest shape of the market: a $5M business run one way prices like the top of a tuck-in, and run another way prices like the bottom of a platform. The band you fall into is a judgment a buyer makes, not a bracket your revenue puts you in automatically.

The arithmetic, on round numbers you can substitute your own into

Take an illustrative contractor at $4M of EBITDA and move it to $5M. Nothing about this is a specific company; substitute your own figures.

On those midpoints, 25% more EBITDA is 88% more company. But the midpoint pairing is a choice, not a property of the data, and the honest range is wide because the two bands overlap between 7x and 8x. Run the same crossing at both extremes:

• $4M at 8x ($32M) to $5M at 7x ($35M) is +9%, for 25% more profit
• $4M at 6x ($24M) to $5M at 9x ($45M) is +88% (midpoints)
• $4M at 4x ($16M) to $5M at 11x ($55M) is 3.4x

All three are consistent with the published bands. Anyone quoting you only the third one is selling something.

So the band change is worth a great deal, and where you land inside the band is worth more than crossing it. An owner who grows EBITDA while ignoring what kind of EBITDA it is can cross a boundary and barely move the price.

What actually moves you across, and it is not revenue growth

Recurring maintenance revenue that is genuinely profitable. Not agreement count, and not the revenue line labeled "service".

Measured across 259 contractors with real service-agreement revenue, the median gross margin on that recurring work is 37.9% and the top quartile reaches 53%. Contractors below about 25% are typically underpricing agreements or failing to capture the maintenance pull-through they have already earned.

That spread is the whole gap between the bands. A buyer paying 4x is buying project revenue that must be won again next year. A buyer paying 11x is buying a maintenance base at 53% margin that renews. Same trucks, same technicians, materially different business, and it shows up in one line of your own P&L long before a broker sees it.

Revenue growth on its own does not do this. Double your install revenue with no change in the agreement mix and you have a bigger tuck-in, priced at 4x to 8x on a larger number.

The three tests a buyer runs before paying the higher band

These are the ones that decide the band, and each is answerable from your own system:

1. Recurring revenue proof. Agreement count, renewal rate, and gross margin per agreement after fully burdened technician hours. Not the revenue category label, the actual burdened margin.
2. Maintenance pull-through. The repair and replacement revenue an agreement customer generates compared with a non-agreement customer. This is what separates an agreement that renews from a discount you give away annually.
3. Install versus service margin split, computed from actual job cost rather than from how the revenue was categorized.

If you cannot produce those three from your own system, a buyer will assume the unfavorable answer and price at the bottom of whichever band they put you in. That assumption is usually worth more turns of EBITDA than anything you say in a management meeting.

What to measure monthly if crossing the band is the plan

• Service-agreement gross margin, burdened. Against a median of 37.9% and a top quartile of 53%.
• Share of EBITDA from recurring work. Not revenue share, EBITDA share.
• Renewal rate, and the reason given for every non-renewal.
• Pull-through ratio: revenue per agreement customer against revenue per non-agreement customer.

Four numbers. They are also the four a buyer will ask for, which is the point: the work of becoming worth more and the work of proving it are the same work.

FAQ

What EBITDA multiple can an HVAC company sell for?

Tuck-ins in the $1M to $5M EBITDA range price at 4x to 8x, regional platforms in the $5M to $25M range at 7x to 11x, and national platforms with high service-agreement density at 15x to 18.5x and above (Capstone Partners, HVAC Services Sector M&A Update). The bands overlap because a $5M business run one way prices like the top of a tuck-in and run another way like the bottom of a platform.

Does growing EBITDA raise my multiple as well as my profit?

It can, because crossing a band re-rates the multiple applied to the whole business. The honest range is wide, because the two bands overlap between 7x and 8x. Taking $4M of EBITDA to $5M is 25% more profit and, depending where in each band you land, anywhere from 9% more enterprise value to 3.4x more, about 88% more at the midpoints. Where you land inside the band matters more than crossing it.

What moves a contractor from the tuck-in band to the platform band?

Recurring maintenance revenue that is genuinely profitable, not revenue growth. Median service-agreement gross margin is 37.9% across 259 contractors and the top quartile reaches 53%. Doubling install revenue with no change in agreement mix produces a bigger tuck-in, priced at 4x to 8x on a larger number.

What will a buyer check before paying the higher multiple?

Three things, each answerable from your own job and agreement data: recurring revenue proof (agreement count, renewal rate, and burdened gross margin per agreement), maintenance pull-through compared with non-agreement customers, and the install versus service margin split computed from actual job cost.

Source and claim note: The band ranges and scopes are EXTERNALLY sourced, not ours. Level does not measure transaction multiples and publishes none of its own; the primary source is Capstone Partners' HVAC Services Sector M&A Update 2026, which also reports a 9.5x average across 2024 to 2026 transactions, corroborated by other published multiple analyses. Private-market multiples vary by deal size, mix and cycle. Businesses under about $1M of owner earnings are usually priced on SDE at lower multiples than the tuck-in band shown here. Service-agreement gross margin is measured from the Level Index across 259 contractors with at least $10K of service-agreement revenue. The worked example uses round illustrative figures so a reader can substitute their own; it is not a specific company's trajectory, and enterprise value in any real transaction depends on far more than one multiple applied to one year of EBITDA.
