Michigan has one of the highest concentrations of aging housing stock in the Midwest — Detroit metro alone has 1.5M+ homes built before 1980. That means recurring HVAC replacement demand, which is exactly what PE buyers price into acquisitions. As roll-up platforms exhaust the Sun Belt's most obvious targets, the Great Lakes region is coming into focus. Michigan HVAC companies are increasingly in play.
A Michigan HVAC business with $1M in EBITDA is worth $4M–$7M+ depending on a specific set of factors that this market makes uniquely important: furnace service agreement attach rates, Detroit metro density, and non-union labor structure. This post explains the math — with real examples, Michigan-specific value drivers, and the worked numbers buyers actually run.
Michigan HVAC Market Context
Michigan's HVAC market is not monolithic. The state has four distinct operating environments, each with different buyer activity profiles:
Detroit Metro (Wayne, Oakland, Macomb Counties)
Largest population center at 4.4M residents, highest deal activity in the state. Buyer competition is growing as national roll-ups like Wrench Group and Apex build density in the market. Companies operating across all three counties command a coverage premium.
Grand Rapids / West Michigan
Fast-growing, less competition for acquisitions. West Michigan's manufacturing base and residential growth make it an attractive secondary market. PE buyers actively scouting here — particularly for businesses with $1.5M–$5M revenue.
Lansing / Flint Corridor
Legacy market with a strong replacement cycle driven by aging housing stock and auto-industry-era commercial buildings. Slower growth, but predictable service demand makes cash flow quality high.
Seasonal Demand Asymmetry
Michigan's harsh winters (furnace-heavy) plus humid summers (AC load) create year-round service revenue that PE buyers model at a premium. The state effectively has two peak seasons, reducing the revenue trough that kills valuations in purely seasonal markets.
Michigan has ~3,500+ HVAC contractors; PE roll-ups typically target businesses with $500K+ EBITDA. One Michigan-specific driver that buyers actively model: the state's high union labor density. Non-union shops command a premium because PE buyers acquiring for roll-up want wage flexibility and margin expansion levers. A well-trained, non-union workforce with documented pay scales is a genuine premium asset in Michigan in a way it isn't in most other states.
Michigan HVAC Valuation Ranges by Revenue Tier
Valuation methodology changes as you cross revenue thresholds. Here are the three tiers Michigan HVAC businesses fall into — and what buyers are actually paying at each level.
Small — $500K–$1.5M Revenue
Businesses at this tier are typically valued on SDE (seller's discretionary earnings), not EBITDA. PE buyers are rarely in the mix at this size — the primary buyers are individual operators and small regional roll-ups.
- Multiples: 2.5x–3.5x SDE
- Example: $500K revenue, owner takes $150K SDE → $375K–$525K valuation
- Buyers: Individual buyers, small regional roll-ups
Mid-Market — $1.5M–$5M Revenue
This is the sweet spot for Michigan acquisitions. PE buyers enter at this size, and valuation shifts to EBITDA-based multiples. Service agreement attach rate matters more in Michigan's mid-market than almost anywhere else — PE buyers specifically model recurring vs. one-time revenue split when underwriting Michigan deals because of the furnace-dependency dynamic.
- Multiples: 4x–6x EBITDA for average companies; 6x–8x for strong performers
- Example: $3M revenue, 18% EBITDA margin = $540K EBITDA → $2.16M–$4.32M base; strong performers hit $3.78M–$4.32M
- Michigan-specific: Attach rate >30% of active customers adds 0.5x–1x to the multiple
Scale — $5M+ Revenue
At this size, you attract the largest PE platforms nationally: Wrench Group, Apex, Service Experts. Geographic density in Detroit metro becomes a premium factor because larger platforms compete specifically for market-coverage positions.
- Multiples: 6x–10x EBITDA
- Example: $10M revenue, 20% EBITDA = $2M EBITDA → $12M–$20M range
- Detroit metro premium: Wayne / Oakland / Macomb coverage positions command buyer competition premium
5 Michigan-Specific Value Drivers
These aren't the generic "recurring revenue matters" factors you'll find in any valuation guide. These are the five factors that specifically move Michigan HVAC multiples — because of what's unique about this market.
Detroit Metro Density
Operating in Wayne, Oakland, or Macomb County? PE buyers pay a premium for service area density. Detroit metro population is 4.4M. A company with 1,500+ active customers in a single metro commands a market-coverage premium that buyers in secondary markets don't compete for. The denser your service territory within the tri-county area, the harder it is for a roll-up to replicate your position organically.
Furnace Service Agreement Attach Rate
Michigan's winters drive furnace dependency in a way that warmer states don't see. A company with 400+ maintenance agreement customers on furnace contracts has a recurring revenue base that looks like SaaS to PE buyers — predictable, high-renewal, low-churn. Attach rate above 30% of your active customers adds 0.5x–1x to your EBITDA multiple in Michigan. Below 15%, you're leaving significant money on the table going into a sale.
Non-Union Labor Structure
Michigan's union density is among the highest in the US. PE buyers acquiring for roll-up specifically model wage flexibility and margin expansion in their underwriting — and a non-union shop gives them those levers. A well-trained, non-union workforce with documented pay scales, technician career tracks, and low turnover is a premium asset in Michigan in a way it isn't in most Sun Belt states.
ServiceTitan or Equivalent Software
No field service software is an immediate valuation haircut. ServiceTitan (or a credible equivalent like Housecall Pro with documented utilization) signals operational maturity. Particularly important in Michigan where active PE buyers run sophisticated diligence — they will ask to see dispatcher utilization, job cost reports, and maintenance agreement tracking. If you can't run those reports, they assume the business is less organized than one that can.
Owner Independence
Detroit-area PE buyers have been burned by key-man risk in prior acquisitions. Can the business run two weeks without you on-site? Documented processes, a strong service manager who holds technician relationships, and a dispatch system that doesn't route every call through the owner represent 0.5x–1.0x in multiple expansion. If you're personally the last call every tech makes, that's the single most impactful thing to fix before going to market.

PE acquisition activity in Michigan is real and accelerating. The platforms actively acquiring in the state include:
| Buyer | Focus Area |
|---|---|
| Wrench Group | Detroit MSA — active platform builder |
| Apex Service Partners | Statewide — Great Lakes region expansion |
| Sila Services | Great Lakes region |
| Sunny Service | Southeast Michigan specifically |
M&A activity in the Great Lakes region has increased 35–45% since 2022. The HVAC companies being acquired are almost all in the $1.5M–$8M revenue range — the mid-market sweet spot where PE roll-ups add the most value through operational improvement and geographic density.
The most common trigger for a Michigan HVAC sale: the owner is 55+, has no succession plan, and receives an unsolicited PE inquiry. That first call almost always arrives with a below-market offer. Most sellers underestimate their value by 20–40% before speaking to an advisor or running a calculator — which means the first offer they receive can look compelling even when it isn't.
Michigan Valuation Example: Running the Numbers
Here's a representative Michigan company and how a PE buyer would actually value it:
Case Study
Grand Rapids HVAC Company, Founded 2009
But a buyer who wants West Michigan density might pay 6x+ to lock out competitors — pushing this to $3.48M. Geographic scarcity is real when roll-ups are competing for coverage positions.
The attach rate in this example (15%) is below the 30% threshold that triggers a meaningful multiple premium. Bringing that to 480+ customers on contracts (30%+ of active base) before going to market is the single highest-ROI preparation step for this business — worth more than any financial restatement or process documentation at this valuation level.

What is my Michigan HVAC business worth?
Most Michigan HVAC businesses with $500K–$5M in revenue sell for 3x–8x EBITDA depending on size, recurring revenue, and PE readiness. Detroit metro companies with strong service agreement programs often command the higher end of that range.
Are PE firms buying HVAC companies in Michigan?
Yes — Michigan is an active acquisition market. Wrench Group, Apex Service Partners, Sila Services, and Sunny Service have all made acquisitions in the Great Lakes region. Deal volume in the Midwest has increased 35–45% since 2022.
What do I need to do to get a 6x EBITDA multiple in Michigan?
Three things matter most: maintenance agreement attach rate above 30%, documented processes that don't require owner presence, and two to three years of clean accrual-basis financials. A ServiceTitan implementation also signals operational maturity to buyers.
