Owner-operated HVAC companies between $1.5M and $5M are some of the most cash-generative businesses in the trades. They have real demand, real customers, and real revenue. What they consistently lack is the operational infrastructure to capture and convert that revenue into durable working capital.
And it is almost always correctable. Four structural gaps show up across nearly every operator we diagnose.
Delayed billing, inconsistent collection, and poor AR discipline turn completed work into 30–60 day receivables that strangle working capital.
High installation dependency and weak service agreement penetration create volatile, lumpy revenue that depresses valuation multiples.
When the owner is the business, every operational and customer relationship risk concentrates in one person — the largest single valuation discount at exit.
Without job-level cost visibility, owners cannot identify which work is profitable and which is subsidizing underperforming revenue categories.
HVAC sits at a specific intersection: highly fragmented ownership, service-agreement float mechanics that reward operational discipline, and a consolidation wave — $50B+ deployed by PE-backed platforms since 2018 — that has already validated exit multiples above the tier Stratum operates in. That validation, combined with clean, comparable diagnostic data, is what makes the Criterion Method's scoring statistically credible over time.
