Home Services Rollups: How to Source HVAC and Plumbing Targets at Scale

Home services rollups are the most active segment in lower middle market M&A, and the most fragmented. A regional HVAC platform in the Sun Belt might need 8–15 tuck-ins over 5 years to hit $15M revenue. Each tuck-in starts as an off-market conversation with a 55-year-old owner in a suburb you've never visited.

Tuck-in criteria that actually work

• SDE $200K–$800K (below $200K, integration cost exceeds value; above $800K, owners expect premium multiples).
• Owner willing to stay 12–24 months (technical knowledge transfer is non-negotiable in trades).
• Service radius overlaps your existing territory or fills a geographic gap.
• Customer base is residential-heavy (more stable than pure commercial for rollups).
• No environmental or licensing liabilities that survive asset purchase.

Sourcing at rollup scale

A solo buyer needs 75 targets. A rollup operator needs 500+ per metro per year as pipeline replenishes. The sourcing system must be continuous, not a one-time list purchase. Weekly refresh, monthly re-scoring, quarterly re-outreach to 'not now' owners.

Integration economics

Pay 2.5x–3.5x SDE for tuck-ins where you keep the owner 12 months. Synergies come from: shared dispatch, consolidated purchasing, unified brand, and back-office centralization. Model each tuck-in standalone first, if it doesn't work without synergies, pass.

Pipeline KPIs roll-up CEOs actually track

Sourcing at scale means weekly numbers: new targets added, Tier-1 outreach completed, meetings booked, LOIs issued, tuck-ins in integration. A regional HVAC platform cannot rely on the CEO's personal Rolodex after deal three. Assign a dedicated sourcing lead or analyst by $8M revenue, their job is universe hygiene, not closing.

• Targets per tuck-in closed: plan 40–60 serious conversations per acquisition.
• Time-to-LOI from first touch: under 120 days for warm off-market, faster for brokered backup.
• Integration capacity: do not sign LOI #4 if tuck-in #2 is still on paper dispatch.

Deal structure for tuck-ins

Platform buyers win with certainty and transition, not always the highest price. Offer 2.5x–3.25x SDE with 12–24 month employment agreements, non-competes, and earnouts tied to customer retention. Stock deals are rare at this size; asset purchases with assigned contracts and vehicle VIN lists are standard. Model synergy separately: if the deal only works with fantasy purchasing savings, pass.

Competing with PE without their wallet

Consolidators pay up for the same $400K SDE shop you want. Your edge is local reputation, speed, and keeping the name on the door. Start outreach before the broker circulates a CIM. Use neglect-scored lists in each submarket you want to densify, PE often ignores operators under $300K SDE until you have rolled five together.

Integration playbook before LOI

Before you sign, know who runs dispatch day one, which ERP or QuickBooks instance survives, and how phone numbers port. Tuck-ins fail when customers call the old main line and reach a dead menu. Budget 90-day dual-brand marketing if you keep the acquired name, cheap signage swaps beat angry Yelp reviews about 'being sold.'

1. Week 0–2: joint town hall with both crews, no layoff surprises on close day.
2. Week 3–6: unify pricing books and warranty policies with seller present.
3. Week 7–12: migrate CRM and retire duplicate software licenses.

Technology and data at rollup scale

Roll-ups drown in disconnected dispatch tools. Diligence should include software inventory: whose CRM wins, how phone trees merge, whether techs will revolt over new apps. Centralize slowly, customers notice missed texts more than they notice logo changes. Your sourcing database should feed integration planning: know which tuck-in uses ServiceTitan vs. pen and paper before you model synergies.

Corporate development hires often come from search backgrounds; give them the same neglect-ranked lists field sales uses so pipeline and integration speak one language.

Retention and earnouts

Key techs leave when the seller leaves unless you communicate early and pay fairly. Structure 10–15% of purchase price as retention pool for named employees over 18 months. Owners know who holds the crew together, ask them on diligence day one, not at the closing table.

• Non-competes for seller with reasonable radius, enforceable matters more than aggressive.
• Customer introduction dinners led by seller in weeks 1–4 post-close.
• Track callback rate weekly for 90 days, early spike means transition failure.

Sourcing committee rhythm

Weekly sourcing standup: new targets added, Tier-1 outreach completed, meetings set, deals in exclusivity. Monthly: retire geographies with poor response, double down where mail plus phone converts. Quarterly: refresh neglect ranks and compare to competitor M&A activity in the same MSA. Roll-ups that treat sourcing as corporate development, not the CEO's side project, hit tuck-in quotas.

Report tuck-in pipeline to the board in units and SDE, not just enterprise value, operators understand trucks and tech count faster than multiples on a slide.

Quality of earnings on tuck-ins

Tuck-in QoE is faster than platform deals but still non-negotiable: normalize owner comp, verify commercial contract assignability, and inspect fleet titles. Roll-ups that skip QoE on 'small' deals inherit warranty and payroll liabilities that erase synergy models.

Standardize a one-page tuck-in diligence checklist across corp dev so every deal captures the same license, fleet, and concentration fields, comparability across acquisitions is how you learn which submarkets overpay.
