Buying an HVAC business in New York

The 30-second version

HVAC businesses are typically priced on a multiple of SDE (smaller) or EBITDA (larger, with a manager in place). The valuation premium comes from recurring service contracts — predictable annual maintenance revenue that lenders and buyers treat as contract revenue. The diligence job is to verify the contract base, the technician certifications (especially EPA Section 608 for refrigerants), and the contractor licensing for the operating area.

How HVAC businesses are valued

Below roughly $500K of SDE, the market prices on SDE. Above roughly $500K of EBITDA, with a general manager in place, it prices on EBITDA. See the SDE vs EBITDA guide for the formulae.

Common HVAC add-backs:

• Owner salary and payroll taxes.
• Depreciation on vehicles and equipment (non-cash — but verify fleet age).
• One-time legal or equipment-replacement fees.
• Personal auto run through the business.

Add-backs a SBA lender will challenge:

• Vehicle repair and replacement — ongoing capex required to maintain revenue, not a discretionary add-back ^[3] .
• Owner 'salary' if the owner is the lead tech and you'll need to hire a replacement at market wages (compare to BLS OEWS for HVAC mechanics and installers ^[7] ).
• Marketing that drives ongoing customer acquisition.

The recurring revenue premium

This is the single most important HVAC valuation factor: what % of revenue is recurring service contracts?

Most established HVAC businesses run a base of annual maintenance contracts, and that base pays predictably through the spring and autumn shoulders. Establish its size first. Then establish its quality — see the contract-book table above. Contract revenue is more valuable than install/repair revenue because:

• It's predictable — lenders and buyers treat it as contract revenue with lower risk.
• It's high-margin — maintenance visits have minimal material cost.
• It's a customer-acquisition channel — maintenance customers convert to install/repair customers.
• It has retention value — contract customers typically renew year-over-year at 85%+ rates.

Two businesses at $1M of revenue can be worth very different money. The one earning 30% of it from contracts prices above the one earning 5%. Diligence question: what % of trailing 12-month revenue was contract vs. install vs. repair? What's the contract renewal rate? How many contracts are auto-renewing vs. cancellable?

New York contractor licensing

NYS does not have a single statewide HVAC contractor license. Instead, contractor licensing is fragmented by jurisdiction:

• NYC Home Improvement Contractor (HIC) license. Required for any work that improves residential property in NYC. Issued by NYC DCWP. The license is held by the business entity, not the individual.
• Westchester, Nassau, and Suffolk each have county-level home improvement contractor licensing. Verify the specific county requirement.
• Many upstate cities and towns have local contractor registration requirements (Buffalo, Rochester, Albany, Syracuse all have specific rules).
• EPA Section 608 certification — federal, not state, but applies to any NYS technician handling refrigerants. Each tech must be certified individually.
• NYSERDA contractor registration — separate from licensing, but required for participation in NYS clean energy rebate programs (a meaningful revenue stream for many HVAC businesses).

Diligence: verify which licenses the target holds, which are entity-level vs. individual, and whether they're transferable on a change of ownership ^[4] .

What the service-contract book is actually worth

The recurring revenue is why HVAC earns a premium at all, so read the contract book harder than you read the P&L. Two books worth the same each year can be worth very different multiples.

One more thing to settle early: HVAC work on residential property sits inside the home improvement definitions used by New York City, Nassau and Suffolk, and those licences do not simply pass to a buyer. See home improvement licences when buying a New York business — the answer can change your deal structure.

HVAC-specific diligence red flags

• Owner is the only EPA-certified tech. If the seller is the only Section 608-certified tech and walks at close, the business loses the ability to perform refrigerant work until a replacement is certified. Reconstruct SDE with the cost of a replacement lead tech at market wages (compare to BLS OEWS ^[7] ).
• Contract base is mostly auto-renewing without active management. Some HVAC businesses have inflated contract counts — the contracts exist on paper but the customer hasn't been contacted in years. Verify active contract counts vs. total contract counts.
• Declining gross margin with stable revenue. Common when the business is buying revenue by underbidding installs. Structural.
• Fleet age. Service vehicles typically need replacement at 150K–200K miles or 8–10 years. A fleet of older vehicles is near-term capex.
• Fuel-provider relationship portability. If the business is an authorized dealer for a major brand (Carrier, Trane, Lennox), verify whether the dealer agreement is portable to a new owner or terminates on a change of control.
• Customer concentration in commercial accounts. Some HVAC businesses derive 25%+ of revenue from one or two commercial property management accounts. Price accordingly.
• Workers' comp claims history. HVAC has a higher injury profile than many service businesses. Pull the trailing 5 years of WC claims history ^[5] .
• Seller pushing to skip the contract base verification. Walk.

New York State-specific items

• NYC DCWP HIC license transfer. NYC home improvement contractor licenses are entity-level and may need to be re-applied for in the buyer's name. Verify with NYC DCWP.
• County-level licensing — verify the specific county requirements for the operating area.
• NYSERDA registration — separate from licensing; affects eligibility for clean energy rebate programs.
• Workers' comp, statutory disability, PFL — mandatory for HVAC employees ^[5] . WC rates for HVAC are typically higher than many service businesses.
• UI registration (NYS 100) via NYS DOL ^[6] .
• Sales tax. Labor for capital improvements to real property is generally not taxable in NY; repair labor is generally taxable. The distinction is significant for HVAC businesses — verify the seller's sales tax collection practice with a CPA.

SBA 7(a) financing for HVAC acquisitions

HVAC is a common SBA 7(a) use case and is viewed favorably by lenders because of recurring revenue and stable customer bases. Key SBA items:

• Max loan $5M; allowed for "changes of ownership" ^[2] .
• Debt service coverage of at least 1.25:1 on a first acquisition, the SOP 50 10 8.1 floor ^[1] ; lenders can ask for more as credit policy ^[3] .
• Buyer equity injection of 10% of total project cost, which SOP 50 10 8.1 states cannot be reduced or eliminated on a first acquisition. ^[1] Lenders often want more — that part is credit policy above the SBA floor. See the equity injection guide.
• Buyer industry experience is heavily weighted. A first-time HVAC operator without technical background will face more scrutiny than an experienced tech.
• Vehicles, tools, and equipment can typically be financed as part of the loan.
• Service contracts may be valued as intangible assets — lenders vary on how they treat them.
