HVAC businesses are among the most actively traded in home services M&A — and for good reason. Strong recurring revenue from maintenance agreements, essential services with 95%+ renewal rates, and aggressive PE consolidation have pushed HVAC multiples to the top tier of the home service sector.
Current HVAC SDE Multiple Range
HVAC businesses are currently trading at 2.5x–5.0x SDE, with the market average around 3.5x. Where your business falls depends almost entirely on four variables: recurring maintenance revenue percentage, owner hours per week, revenue growth trend, and whether you have a management team that can run operations without you. A business checking all four boxes can command 4.5x–5.0x. A business with no maintenance contracts and an owner working 60 hours a week will be at 2.5x–3.0x.
What PE Buyers Are Paying for HVAC
Private equity buyers are the most active acquirers in HVAC M&A. Platforms like Apex Service Partners, Authority Brands, and dozens of regional PE-backed roll-ups are acquiring HVAC companies for 5x–8x EBITDA. These are businesses with $500K+ EBITDA, strong residential maintenance agreement bases, and management depth. The key to a PE transaction isn't just size — it's positioning. Businesses that look like platform candidates (systemized, scalable, recurring) get PE interest. Businesses that look like one-man shops don't, regardless of revenue.
The Recurring Revenue Premium in HVAC
The single biggest driver of HVAC valuation multiples is maintenance agreement penetration. HVAC businesses with 40%+ of revenue from annual service agreements consistently trade at a 0.5x–1.0x premium to their peers. The math is simple: buyers are purchasing a stream of future revenue, not just last year's earnings. An HVAC company with 1,500 maintenance agreement customers at $200/year has $300K in recurring revenue that renews at 90%+ annually — that's a very different business than one doing the same revenue entirely from break-fix calls.
HVAC Multiple Benchmarks by Business Size
Small HVAC businesses ($500K–$1.5M revenue): 2.5x–3.5x SDE. These sell primarily to individual buyers or small operators. SBA financing is common. Mid-market HVAC ($2M–$5M revenue): 3.0x–4.5x SDE / 5x–7x EBITDA. More buyer types including strategic acquirers. PE add-on territory. Larger HVAC platforms ($5M+ revenue): 4.0x–5.5x SDE / 6x–9x EBITDA. Primary PE territory. These deals often include equity rollover and earnout components.
What's Dragging HVAC Multiples Down
The discounts are predictable: owner works 50+ hours per week in the field (key man risk), no maintenance agreement program, heavy commercial work with thin margins, aging fleet or equipment, customer concentration above 20%, and undocumented financials. Each of these is fixable — but not overnight. Sellers who start addressing them 12–18 months before going to market consistently achieve 0.5x–1.5x higher multiples than those who decide to sell next month.
