Multiple Arbitrage in HVAC
HVAC is the most active multiple arbitrage category in home services. Firms like Wrench Group have demonstrated that buying independent HVAC companies at 4x to 5x and building them into regional platforms can create 10x+ exit valuations. The math is straightforward but the execution requires operational discipline.
This calculator models the full HVAC roll-up process. Enter your platform acquisition details, bolt-on assumptions, operational improvements, and exit multiple to see the total return profile. The PE firms running HVAC roll-ups are generating 2.5x to 4x MOIC over 5-year hold periods. The arbitrage spread between entry and exit multiples drives the majority of returns.
How HVAC Roll-Ups Work
HVAC roll-ups work because of three factors: fragmentation (76% of HVAC companies are independently owned), strong recurring revenue from maintenance agreements, and the ability to improve margins through scale. The platform acquires smaller shops, integrates them into shared dispatch and marketing systems, standardizes pricing, and leverages bulk purchasing. Each bolt-on immediately benefits from lower overhead as a percentage of revenue.
HVAC PE Benchmarks
HVAC PE benchmarks: platform acquisition multiples 6x to 8x, bolt-on multiples 3x to 5x, typical exit multiples 8x to 12x for regional platforms, 12x to 15x for national platforms. Wrench Group: 12x to 14x exit. Sila Services: approximately 15x valuation. Average MOIC for successful HVAC roll-ups: 2.5x to 4x over 5 years. Typical bolt-on count: 3 to 8 over the hold period. Margin improvement from integration: 2% to 5% EBITDA margin expansion.
Tips for HVAC Roll-Up Strategy
- The entry multiple on bolt-ons drives returns more than almost any other variable. Every 0.5x reduction in bolt-on entry multiple increases MOIC by approximately 0.3x. Negotiate hard on bolt-on pricing.
- Maintenance agreement customer bases are the most valuable asset in HVAC bolt-ons. A bolt-on with 800 maintenance agreements and average EBITDA is worth more than one with above-average EBITDA and no recurring revenue.
- Integration speed matters. PE firms that integrate bolt-ons within 90 days capture margin improvements faster. Delayed integration means months of sub-optimal operations.
- Geographic clustering creates value beyond multiple arbitrage. Bolt-ons in adjacent markets enable route density, shared technicians, and reduced travel time. Scattered acquisitions across distant markets destroy the operating model.
Frequently Asked Questions
What is multiple arbitrage in HVAC?
Multiple arbitrage is buying HVAC companies at low EBITDA multiples (3x to 5x) and selling the combined entity at a higher multiple (8x to 12x). A PE firm buys a $1.5M EBITDA platform at 7x and four bolt-ons at 4x each. The combined $3.1M EBITDA company exits at 10x, creating significant value from the multiple spread alone, before any operational improvements.
How do PE firms roll up HVAC companies?
PE firms start by acquiring a well-run HVAC platform with professional management, typically at 6x to 8x EBITDA. They then acquire 3 to 8 smaller HVAC companies at 3x to 5x over 3 to 5 years. Each bolt-on is integrated into the platform, sharing its back office, dispatch, marketing, and management. The combined entity is larger, more stable, and commands a premium exit multiple.
What multiples have HVAC companies sold for?
Wrench Group, a PE-backed HVAC platform, sold at 12x to 14x EBITDA. Sila Services was valued at approximately $1.5B at roughly 15x EBITDA. These are platform-level multiples for businesses with $50M+ EBITDA. Individual HVAC companies sell at 3.5x to 5x (owner-dependent), 5x to 8x (managed), and 8x to 12x (regional platforms with $3M+ EBITDA).
How do HVAC bolt-on acquisitions create value?
Each bolt-on purchased at 4x that exits at 10x creates immediate arbitrage value. A $400K EBITDA bolt-on bought for $1.6M (4x) is worth $4M at exit (10x). That is $2.4M in value created per bolt-on. Operational improvements (shared dispatch, bulk purchasing, standardized pricing) add another 2% to 5% to margins, increasing the EBITDA base before the exit multiple is applied.
What makes an HVAC company a good platform acquisition?
A good HVAC platform has $1M+ EBITDA, a general manager and service manager in place, strong brand recognition in its market, 1,000+ maintenance agreements, and clean financials. The platform provides the management infrastructure, back office, and systems that bolt-on acquisitions will be integrated into. Without strong platform infrastructure, the roll-up strategy fails.
