The HVAC M&A Guide

Most HVAC companies are valued as a multiple of adjusted EBITDA — earnings after normalizing owner salary, personal expenses and one-time costs. Smaller shops (under $1M EBITDA) often trade at 3–5x; larger, well-run platforms with strong service revenue can reach 6–10x or more.

Recurring revenue is the single biggest lever. A large base of maintenance agreement members tells a buyer future service calls and replacement leads are predictable.

Revenue mix matters too: residential replace-and-service businesses, commercial service contracts and new-construction work are each valued differently. New construction is typically the least valued because it's cyclical and low margin.

Private equity platforms are rolling up HVAC, plumbing and electrical companies nationwide. They often pay well and offer rollover equity, but expect growth and reporting.

Strategic buyers — larger regional contractors — may value your territory, techs and customer list, and can move quickly.

Independent buyers, family successors and employee buyouts usually involve more seller financing, but can preserve your legacy and culture.

Owner dependency: if you sell every system and every customer calls your cell, buyers discount for risk. A general manager and sales lead change that.

Technician bench: licensed, trained, retained techs are scarce. Low turnover and a training program are worth real money.

Systems: a modern FSM platform (ServiceTitan, Housecall Pro, etc.), clean job costing and accurate financials shorten diligence and increase confidence.

Concentration: one builder, property manager or GC making up a big share of revenue is a red flag.

Cash at close is the lowest risk. Earn-outs tie part of the price to future performance — and are where sellers most often lose value.

Seller notes mean you're financing part of the purchase. Rollover equity gives you a stake in the buyer's company and a potential 'second bite' when the platform sells.

Employment and non-compete terms, working capital targets and how equipment and real estate are handled all affect what you actually keep.

Buyers pay for your trailing results. The work that raises your price — growing memberships, hiring a GM, cleaning up books — takes 2–3 years to show up.

Health, burnout and family events force many owners to sell reactively. Planning early means you choose the timing, not the other way around.

1. Preparation — financial recast, valuation, and a confidential profile of the business.

2. Marketing — targeted, confidential outreach to qualified HVAC buyers under NDA.

3. Offers — management meetings, competing letters of intent (LOIs), and negotiation.

4. Diligence — financial, legal, licensing, fleet and HR review. Typically 60–120 days.

5. Close & transition — funding, announcing to employees and customers, and handing off well.
