Buying an HVAC business in New York

HVAC is one of the most attractive New York home-services acquisitions — predictable recurring revenue from service contracts, two seasonal demand peaks (heating and cooling), and a stable customer base of older housing stock. It also has a real NY-specific licensing overlay that buyers miss at their peril.

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

Smaller HVAC businesses (SDE below ~$500K) are typically priced on a multiple of SDE. Larger HVAC businesses with a general manager in place (EBITDA above ~$500K) are typically priced on a multiple of 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 ^[2] .
• 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 ^[6] ).
• 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 have a base of annual maintenance contracts (typically 100–500+ contracts) that produce predictable, high-margin revenue in the spring and fall shoulder seasons. 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 with $1M revenue can be priced very differently: one with 30% contract revenue commands a higher multiple than one with 5% contract revenue. 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 ^[3] .

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 ^[6] ).
• 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 ^[4] .
• 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 ^[4] . WC rates for HVAC are typically higher than many service businesses.
• UI registration (NYS 100) via NYS DOL ^[5] .
• 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" ^[1] .
• DSCR typically 1.15–1.25 ^[2] .
• Buyer equity injection typically 10% minimum (often more).
• 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.
