The HVAC Roll-Up Thesis in 2026: What's Working, What's Broken

Four years into the HVAC consolidation wave, the winners and losers have separated. Here's what the operating data says.

Residential HVAC has been the most-consolidated trade in North America for four years running. The thesis was sound: fragmented ownership, recurring maintenance revenue, replacement cycles, and licensing moats. The execution has separated cleanly into what works and what doesn't.

What's working

• Regional density plays. Operators who bought three to eight businesses inside a single metro and consolidated dispatch, procurement, and back office are compounding.
• Maintenance agreement conversion. Platforms that pushed MSA attach rates from 25% to 60%+ have durable, defensible recurring revenue tails.
• Journeyman-to-tech pipelines. Winners built training programs. Losers tried to poach — and paid for it in wage inflation.
• Financing at the point of sale. Consumer financing on system replacements moves close rates by 30–40%. Table stakes now, differentiator two years ago.

What's broken

• National roll-ups without regional density. One shop in each of twelve markets is twelve businesses to run, not a platform.
• Over-leveraged platforms with floating-rate debt. Rates went the wrong way. Debt service is eating growth capex.
• Culture collapse post-close. Techs quit when the founder leaves and the new owner shows up with a scorecard. Platforms with 30%+ tech turnover in year one rarely recover.
• Deferred capex on truck fleets. The fleet is the business. Deferring replacement to hit EBITDA targets is a two-year problem you can't hide.

Where the next cycle goes

The next winners look less like roll-ups and more like operating platforms — regional density, strong ops, patient capital, and the discipline to walk away from deals that don't fit the geography. The multiple-arbitrage era is largely done. The operating-alpha era is starting.
