Question 1

How do I sell my HVAC business?

Accepted Answer

Selling an HVAC business is a 6 to 12 month process when run correctly. Step 1: clean up financials so a quality-of-earnings (QofE) firm can normalize EBITDA — separate owner add-backs, document recurring service-plan revenue, and reconcile your ServiceTitan/Housecall Pro/FieldEdge data to your tax returns. Step 2: hire an M&A advisor (above ~$500K of EBITDA) or a business broker (below it) and decide between a strategic, private equity, or family-office buyer. Step 3: market confidentially under NDA to a curated buyer list, run a competitive process to drive multiple expansion, and negotiate IOIs and an LOI. Step 4: manage 60–90 days of buyer diligence, sign a stock or asset purchase agreement, and close. Skipping prep is the single biggest reason HVAC deals retrade lower or break.

Question 2

What is the $5,000 rule for HVAC?

Accepted Answer

In HVAC, the "$5,000 rule" is a homeowner repair-vs-replace heuristic, not a regulation. You multiply the cost of the repair by the age of the system in years, and if the result exceeds $5,000 you typically replace the unit instead of repairing it. Example: a 12-year-old system with a $500 repair = $6,000, so replace; a 7-year-old system with a $400 repair = $2,800, so repair. From a buyer's perspective on an HVAC business sale, the rule is relevant because it predicts your replacement-vs-repair revenue mix — and a healthy 35–50% revenue contribution from system replacements is one of the multiple drivers acquirers underwrite.

Question 3

How much is a business worth with $100,000 in sales?

Accepted Answer

For an HVAC business with only $100,000 in annual revenue, valuation is driven by Seller's Discretionary Earnings (SDE) — owner take-home plus add-backs — not EBITDA. Per BizBuySell's benchmarks, small HVAC businesses transact at roughly 2.0x–3.3x SDE, with a median around 2.75x. If a $100K-revenue HVAC operator nets $30K–$45K of SDE, the realistic sale price is $60K–$120K, usually as an asset purchase. Below ~$500K of EBITDA, deals are Main Street rather than M&A: shorter timeline, simpler structure, and typically transacted with a flat-fee business broker rather than a sell-side advisor.

Question 4

How much is my HVAC business worth?

Accepted Answer

For lower middle-market HVAC companies, the formula is: adjusted EBITDA × industry multiple. Adjusted EBITDA = net income + interest + taxes + depreciation + amortization + owner add-backs (above-market salary, personal expenses, one-time items). Industry multiples for HVAC in 2024–2025 generally land between 4x and 9x EBITDA. A residential service-led HVAC business with $1M of adjusted EBITDA, 30%+ service-plan attach rate, technician scale, and clean books typically clears 7x–9x — implying a $7M–$9M enterprise value. Sub-$750K EBITDA shops trend toward 4x–5x; PE platform deals at $3M+ EBITDA with strong recurring revenue can clear 9x. The fastest way to a real number is a free valuation that runs your specific revenue mix, customer concentration, and EBITDA quality against recent comparable transactions.

Question 5

What multiple do HVAC businesses sell for?

Accepted Answer

HVAC businesses generally sell for 4x to 9x adjusted EBITDA depending on size, mix, and recurring revenue. Sub-$1M EBITDA businesses transact in the 3x–5x SDE/EBITDA range. PE platform deals at $3M+ EBITDA with strong residential service mix often clear 7x–9x EBITDA. The single biggest multiple drivers are recurring service-plan revenue (membership penetration above 30% with 75%+ renewal rate), replacement-vs-repair mix (35–50% replacement is the sweet spot), low customer concentration (no single customer above 10% of revenue), and an operating team that runs the business without the owner.

Question 6

How long does it take to sell an HVAC business?

Accepted Answer

A well-prepared HVAC sell-side process typically runs 6–9 months: 4–8 weeks of preparation (QofE, CIM, customer cohort analysis), 60–90 days of marketing and buyer outreach producing IOIs, 30–45 days of LOI negotiation and exclusivity, and 60–90 days of confirmatory diligence and definitive-agreement negotiation through closing. Owners who skip the preparation phase routinely lose 6–12 months and 10–20% of headline value to retrades during diligence.
