Buy a Generator Service Business in 2026: 4-9x EBITDA, PM Attach Rates, Dealer Dynamics

Updated June 2026 · CT Acquisitions

Buying a generator service business in 2026 sits at the intersection of three powerful capital flows: residential standby demand pulled forward by a decade of grid instability, the $1.2T Infrastructure Investment and Jobs Act funding commercial and utility backup, and a wave of MEP-electrical and home-services consolidators looking for sticky, contract-driven add-ons. Generac controls roughly 70% of the residential standby market and runs a tightly managed dealer program. Cummins (NYSE: CMI) and Kohler dominate the commercial and industrial segments through direct dealer territories and certified service networks. For buyers, the generator service category offers something rare: recession-resistant demand, structural tailwinds, and a base of 6,000-plus independent operators where the median seller is over 60 years old and the median operation still runs on paper service tickets.

This guide is the buyer’s playbook for the generator service vertical. It covers how generator service businesses are underwritten in 2026, which operational signals separate a 4x deal from a 9x platform, how Generac, Cummins, and Kohler dealer status changes valuation, what deal structures sellers accept, and how to close acquisitions that actually compound after the transaction.

Why generator service is a conviction buy in 2026

Three structural tailwinds make buying a generator service business one of the highest-conviction trades in the home services and MEP-adjacent landscape right now.

First, grid instability is structural, not cyclical. The North American Electric Reliability Corporation flagged elevated reliability risk across the MISO, ERCOT, SPP, and WECC footprints through 2030. Average outage duration per customer (SAIDI) has roughly doubled since 2013 per EIA data. Hurricane intensity, wildfire-driven Public Safety Power Shutoffs in California, and ice-storm vulnerability across the Texas grid have pulled forward residential standby demand by a decade. Generac shipped record residential units through 2024 and 2025 and management has repeatedly cited a multi-year installed-base inflection.

Second, commercial and industrial backup is funded. The $1.2T Infrastructure Investment and Jobs Act, paired with grid-hardening spend by IOUs and the data center build-out, has put commercial standby into a sustained capex cycle. Hospitals, water and wastewater facilities, telecom, cold storage, and data centers all have either regulatory (NFPA 110, NFPA 99 for healthcare) or operational requirements for backup power. That work routes through Cummins, Kohler, MTU, and Caterpillar authorized dealers, and the service tail on each install runs 15 to 25 years.

Third, fragmentation plus aging ownership. There are roughly 6,000 independent generator service operators in the US. The top 10 control well under 15% of the market. Median owner age is north of 60. Generac’s Premier and Elite dealer programs have created a ranked pool of identifiable consolidation targets, and Cummins Sales and Service and CESCO have demonstrated that direct dealer rollups work at scale.

For buyers, the combination is unusual: a category with subscription-like preventive maintenance economics, a regulatory and weather demand backstop, and enough supply of identifiable quality targets to build a real platform. The challenge is that sophisticated sellers know all of this, and pricing in the $2M-plus EBITDA band has tightened materially since 2023.

What buyers are actually paying for generator service in 2026

Valuation ranges in generator service are wide because the operational spread is wide. A $1M EBITDA residential install-heavy Generac dealer with 25% preventive maintenance attach is a fundamentally different asset than a $1M EBITDA business with 60% PM attach, a Cummins or Kohler authorized service territory, and an industrial install base. The multiples reflect the difference, and dealer status often matters as much as financial profile.

The spread between 4x and 9x is not random. It is driven by six factors that every sophisticated generator service buyer models explicitly:

• Preventive maintenance attach rate. The single largest multiple driver. Buyers apply platform multiples (7x to 9x) to recurring PM revenue and the warranty plus repair revenue PM agreements generate. They apply project multiples (3x to 4x) to one-off install and emergency-only revenue. 40% to 65% PM mix is the benchmark range for institutional buyers.
• Dealer status and territory. Generac Premier or Elite tier, Cummins authorized dealer status, Kohler dealer status, and authorized service-only relationships with MTU, Caterpillar, or Onan each carry territorial value. Multi-brand authorized dealers command 20% to 30% premiums because dealer agreements are not freely transferable and an acquirer cannot replicate them by buying inventory.
• Install plus service plus sell integration. Operators that originate the install, run the warranty service, sell the PM contract, and own the upgrade or replacement cycle have a closed-loop economic position that pure-service or pure-install operators cannot match. The integrated lift typically adds 1.0x to 1.5x EBITDA.
• Commercial and industrial mix. Residential-only operators are exposed to Generac unit pricing, weather variance, and a 7 to 12 year replacement cycle. Commercial and industrial operators have NFPA 110 and NFPA 99 compliance work, contracted load-bank testing, fuel polishing, and 15 to 25 year service tails. Commercial mix above 40% typically supports 1.0x to 2.0x premium.
• Technician retention and certification. EGSA-certified technicians and brand-trained service personnel are scarce. Annualized voluntary turnover below 15% suggests a functioning culture; above 30% signals operational fragility and integration risk.
• Geographic exposure. Operators in TX, FL, LA, NC, SC, GA, and AL benefit from hurricane-driven recurring demand. California operators benefit from PSPS-driven standby adoption. Operators in stable-weather markets without commercial or industrial concentration receive lower multiples.

The 2026 pricing reality

Because MEP-electrical consolidators and dealer-rollup platforms are aggressively competing for quality targets, the $2M to $10M EBITDA band has tightened materially. Platform-grade Generac plus Cummins or Kohler dealers in the $3M-plus EBITDA range routinely receive multiple LOIs at 7.0x to 9.0x. Founders are getting sophisticated; the “I had no idea generator businesses traded for that” era is largely over.

For independent and search-fund buyers competing with platforms, the implication is straightforward. You either need a differentiated thesis (geography the platforms have not entered, sub-segment such as marine or telecom that does not fit the standard playbook, or operator profile under the platforms’ size threshold), or you need to move to the $500K to $1.5M EBITDA band where dealer rollups and MEP consolidators are less active. In that range, valuations are still 3.5x to 5.5x SDE and founders often prioritize continuity over price.

The six buyer archetypes in generator service

Understanding which buyer you are (and which you are competing against) changes how you structure offers in the generator service space.

1. Generac dealer-rollup platforms

Regional and increasingly national platforms acquiring Generac Premier and Elite dealers to build geographic density. Examples include Acme Generators, Power Pro-Tech, and a growing cohort of PE-backed Generac-focused consolidators. They target $1.5M to $10M EBITDA operators with strong residential PM books. They pay the highest multiples for Generac Elite dealers in hurricane and grid-stress geographies and move fast on diligence because they have a standard underwriting model.

2. Cummins and Kohler direct or licensed dealer acquirers

Cummins Sales and Service (the direct distribution arm of NYSE: CMI), CESCO, and large Kohler distribution territory holders consolidate authorized commercial and industrial service operators. They are particularly active where territorial coverage is incomplete or where a dealer is retiring. They pay competitive multiples because dealer agreement transfer is contingent on OEM consent, which they internally control.

3. MEP-electrical consolidators

Regional and national MEP-electrical platforms (frequently PE-backed) absorb generator service operators to add a recurring-revenue, contract-driven service line to a project-heavy MEP business. The strategic logic is that an MEP electrical contractor already controls the transfer switch installation, the gear, and the customer relationship. Adding generator service captures the 15 to 25 year service tail on every install. Multiples paid are competitive (typically 6x to 8x) when the target has a strong commercial and industrial mix.

4. Independent sponsors and PE-backed standalone platforms

Deal-by-deal capital and standalone PE platforms focused on the generator vertical specifically. They compete on creative structuring (earnouts, rollover equity, seller financing) when they cannot match strategic pricing. Good fit for sellers who want a long-term operating partner and meaningful continued upside.

5. Search funds

Individual operators with institutional backing looking for one business to run. Typical target profile: $500K to $2M SDE, established residential PM base, processes that do not require the founder daily. Multiples: 4x to 6x SDE. Good fit for founders who want a clean exit and are willing to trade some price for a buyer who plans to stay and run it.

6. Self-funded operator rollups

Operator-led roll-ups funded by a combination of seller financing, SBA 7(a), and mezzanine. Cannot match platform pricing but can move fast on smaller deals ($500K to $1M EBITDA) and often offer the strongest operational continuity story. Particularly common in geographic pockets where the major platforms have not yet entered.

Due diligence: the generator service deep dive

Generic M&A diligence is necessary but not sufficient when buying a generator service business. The category-specific signals are where value creation and value destruction actually happen. Here is what experienced generator service buyers do in addition to standard quality of earnings, legal, and insurance review.

Revenue mix decomposition

Do not accept the seller’s definition of recurring revenue. Pull 24 to 36 months of transactional data and bucket every invoice into: residential new install, commercial or industrial new install, transfer switch installation, preventive maintenance contract, load-bank testing, fuel polishing, warranty service, emergency repair, parts sales, generator sales pass-through, and rental. The boundaries are fuzzy and sellers classify aggressively. Buyers who do not rebuild the mix routinely overpay.

Preventive maintenance contract analysis

For every active PM contract: install date of the underlying generator, contract acquisition date, current annual contract price, renewal date, renewal history, scheduled visit completion rate, and conversion rate to warranty plus repair revenue. A healthy generator service PM book shows:

• Over 90% annual renewal rate
• Over 90% scheduled annual visit completion (most residential PM is one or two visits per year)
• 30% to 50% of PM customers generating warranty or repair revenue annually
• Customer tenure distribution with healthy ingress, not just an aging install base
• Contract pricing repriced within the last 24 months

Red flags: contracts with below-market pricing that have not been repriced in 3-plus years, contracts where the completion rate is falling (suggesting scheduling or technician capacity problems), and cohorts where renewal is dropping in years 2 to 3 (suggesting a satisfaction or pricing issue).

Dealer agreement audit

This is the category-specific item that generic buyers consistently miss. Generac, Cummins, Kohler, MTU, and Caterpillar dealer agreements are all subject to OEM consent on change of control. Pull every dealer and authorized service agreement. Confirm:

• Dealer tier (Generac Premier vs Elite, Kohler standard vs Power, Cummins authorized vs distributor)
• Territory definition and exclusivity terms
• Performance metrics the OEM uses (units sold, warranty claim rate, customer satisfaction, training completion)
• Change-of-control provisions and historical OEM consent practice
• Co-op marketing dollars and any clawback exposure
• Inventory commitments and stocking requirements

For Generac specifically, the Premier and Elite tier qualifications include training certifications, response time SLAs, and minimum sales volumes. An acquirer that strips out the founder or reduces sales effort can lose tier status, which can drop margins by 200 to 400 basis points within 12 months.

Hurricane-season revenue normalization

For operators in TX, FL, LA, NC, SC, GA, AL, MS, and the Gulf and Atlantic coasts, residential install revenue is meaningfully storm-correlated. A year with an active hurricane season can lift unit sales 40% to 80% above baseline. An accurate underwriting requires a 5-year look-back, normalization against NOAA-tracked named-storm landfalls, and an understanding of which revenue is structural and which is event-driven. Buyers who underwrite off a hurricane-active trailing year often overpay by 1x to 2x EBITDA.

Transfer switch installation margin

Automatic transfer switch installation is a high-margin sub-line that some operators run profitably and others run breakeven. Pull job-level margin on the trailing 12 months of ATS installs. Top operators run 45% to 60% gross margin on the labor component because they have standardized the install, trained crews, and minimized callbacks. Operators below 30% typically have a training or scoping problem.

Technician unit economics

Build a technician-level P&L for the trailing 12 months. Key metrics: billable hours per technician per day (target: 5.5 to 6.5 for service techs), PM visits completed per day, average ticket size, first-time-fix rate, callback rate, and individual gross margin contribution. EGSA-certified and brand-trained technicians are the binding capacity constraint in this category, and the delta between top-third and bottom-third technicians often exceeds 50%.

Dispatch and CRM technology

If the business uses ServiceTitan, FieldEdge, Housecall Pro, or a generator-specific platform such as PowerService or eAuditor, request read-only reporting access. Analyze route density, PM schedule adherence, after-hours response times, and parts inventory accuracy. If the business runs on spreadsheets and paper tickets (still common in this category), plan and underwrite a 9 to 15 month post-close CRM implementation.

Customer concentration stress test

Pull the top 20 customers by revenue and trailing 12-month gross profit. In commercial-heavy operators, single hospital, telecom, or data center accounts can represent 15% to 25% of revenue. Model loss scenarios where 50% of the top-5 commercial accounts churn post-close. For multi-site commercial customers, identify which contracts are at the parent or facility level, since parent-level contracts are easier to lose if the buyer’s name lacks the prior incumbent’s reputation.

Regulatory and compliance

State electrical contractor license status, EPA Tier 4 emissions compliance on rental and recent install fleet, NFPA 110 and NFPA 99 documentation for commercial and healthcare service customers, OSHA recordable history (lock-out tag-out compliance is critical), workers’ compensation claim history, and fuel handling permits where applicable. Generator service is electrical-trade-licensed in most states, and license-holder dependence on a single individual (often the founder) is a category-specific risk.

Structuring the offer

The best buyers in generator service win on structure as often as on price. A well-structured offer can beat a higher nominal offer if it matches what the seller actually cares about.

The standard generator service deal structure (2026)

• Cash at close: 65% to 75% of total consideration.
• Seller rollover equity: 5% to 15% in platform deals where the seller continues operating. 0% in clean-exit deals.
• Earnout: 10% to 20% over 12 to 24 months, typically tied to PM contract retention rates and dealer-tier preservation (not raw EBITDA, because buyers control post-close overhead).
• Escrow: 10% held 12 to 18 months against indemnification claims, with separate carve-outs for dealer agreement consent and license transfer.
• Seller note: 0% to 10%, typically subordinated to senior debt. Common in independent sponsor and search-fund deals; less common in platform deals.

Where smart buyers differentiate

The offer components sellers weight most heavily (in approximate order): cash at close percentage, earnout achievability, dealer relationship preservation commitments, key technician retention packages, license-holder transition plan, and timeline certainty. Headline price is often the 5th or 6th factor for founders approaching retirement.

Buyers who win on non-price factors typically: pre-commit to technician retention bonuses (commonly 3 to 6 months salary for named EGSA-certified technicians), write earnouts with achievable floors (90% PM retention triggers a minimum payment, with upside for overperformance), and structure the OEM dealer agreement transition jointly with the seller (which sellers appreciate because failed dealer transfers can trigger their indemnity exposure).

The earnout trap

The single most destructive element of a generator service deal is a poorly designed earnout. If tied to EBITDA, sellers justifiably worry about post-close cost allocation and typically will not perform. If tied to top-line revenue, sellers may focus on revenue and ignore margin or push project work that destroys long-term economics. If tied to new install bookings, sellers can be exposed to hurricane variance they do not control.

The structures that work in generator service: PM contract retention percentage (measured against a closing-date baseline of named accounts), dealer-tier preservation (Generac Elite status maintained through year one), and EGSA-certified technician retention rate. All three are things the seller can meaningfully influence in the first 12 to 18 months post-close.

Integration: where acquirers create or destroy value

Generator service integration is more nuanced than HVAC or plumbing because the OEM relationships sit between the business and the customer. The deals that compound are the ones where buyers respect three principles.

Protect dealer-tier status before anything else

Generac Premier and Elite tier, Kohler dealer status, and Cummins authorized status are revoked or downgraded for cause. Common causes include falling unit volumes, missed training requirements, customer-satisfaction failures, warranty-claim irregularities, and inadequate territorial coverage. The first 90 days post-close are when these slip. Smart buyers ringfence the dealer relationship, retain the OEM liaison (often the founder or sales manager), and prove out tier preservation before changing anything else.

Lock in EGSA-certified and brand-trained technicians

Generator service technicians are harder to replace than HVAC techs because Generac, Cummins, and Kohler brand certifications take 12 to 24 months to obtain and require OEM-controlled training slots. Once a deal is announced, competitors and OEM dealers in adjacent territories reach out within 48 hours. Smart buyers structure retention bonuses (typically 10% to 20% of annual compensation, paid in 12 to 18 months) for named EGSA-certified and brand-trained technicians, with the bonus contingent on remaining employed and maintaining certifications. This should be finalized before close.

Do not break the install plus service plus sell loop

The strongest generator service businesses run a closed-loop economic model: originate the install, capture the PM contract on day one, own the warranty work, sell the replacement 8 to 12 years later. Buyers who silo the install function from the service function (a common move when an MEP electrical platform absorbs a target) frequently break this loop. The PM attach rate on new installs falls within 6 months, and the long-term value-creation thesis evaporates. Preserve the closed loop in year one; restructure deliberately over 18 to 24 months if at all.

Financing a generator service acquisition

Capital structure varies by buyer type, but some patterns are consistent in 2026 for generator service deals.

SBA 7(a) loans

Independent buyers and search funders commonly use SBA 7(a) financing for deals up to $5M. SBA rates are typically prime plus 2.0% to 2.75%, with 10-year amortization. The constraint: SBA requires the seller to exit operationally within 12 months and limits seller financing structures. For generator service deals where the founder also holds the state electrical license, SBA can be tricky and the buyer needs a credentialed replacement in hand.

Commercial bank acquisition lending

Regional and community banks with home services or MEP experience will lend 2.0x to 3.5x EBITDA at prime plus 1.5% to 2.5%. Cash flow covenants are typical. Best for deals where the business has predictable PM-driven margins and clean financials. Banks familiar with the generator vertical (commonly those that have lent to Generac, Cummins, or Kohler dealers in the past) are more comfortable underwriting the dealer-agreement intangible.

Mezzanine and unitranche

For platform deals or larger independent deals ($5M-plus EBITDA), mezzanine or unitranche financing bridges the gap between senior debt and equity. Rates run 10% to 14% with warrants. Common providers in this space include Twin Brook, Monroe, Antares, and regional SBIC funds with industrial-services experience.

Seller financing

Often 5% to 15% of purchase price, subordinated, 5 to 7 year term. Rates typically 6% to 8%. Particularly useful in generator service deals where the seller’s ongoing involvement (license-holder transition, OEM relationship handoff) makes a seller-note structure align incentives.

Red flags that kill generator service deals

Some deals should not close. The patterns that consistently predict post-close failure in generator service:

• Quality of earnings reveals over 15% EBITDA adjustment. Usually from owner compensation, related-party transactions, or aggressive revenue recognition on long-duration PM agreements. A 10% to 15% adjustment is normal. Above that range, the diligence premium typically makes the deal uneconomic.
• Dealer agreement transfer is uncertain. If Generac, Cummins, or Kohler has historically been slow to consent in change-of-control situations in the territory, or if the target’s tier status is on watch, the entire valuation premium can evaporate at OEM approval. Get pre-approval indication before signing.
• License-holder is the founder, with no successor. In most states the master electrician license or generator-specific contracting license is held by one named individual. If that person is the seller and there is no qualified employee credentialed to replace them, the business literally cannot operate post-close until the buyer obtains licensure. This is a 90 to 180 day risk that needs to be solved before signing.
• Hurricane-active trailing year used as base case. An operator riding a Beryl, Helene, or Milton year showing a 60% revenue lift is not a 60% larger business going forward. Normalize against a 5-year hurricane-adjusted baseline.
• Technician turnover exceeds 30% annually. Particularly damaging in generator service because OEM-certified technician replacement takes 12 to 24 months. In a tight labor market this can destroy the thesis.
• Warranty claim rate above OEM benchmarks. Generac and Cummins both publish dealer warranty-claim benchmarks. Targets running materially above benchmark are at risk of dealer-tier downgrade and may have a quality or training problem the buyer will inherit.
• Workers’ compensation experience modifier above 1.20. Generator work involves high-voltage electrical, fuel handling, and lift work. A high EMR signals safety culture problems and meaningfully raises post-close insurance cost.

The CT Acquisitions perspective

We work both sides of the generator service market: introducing sellers to qualified buyers and sourcing deal flow for institutional buyer networks that have engaged us. Our observations from recent generator service M&A activity:

• The best deals are not always the highest-priced. Sellers who get the strongest outcomes prioritize buyer fit (dealer relationship preservation, technician retention, license-holder transition) alongside price. Buyers who credibly signal these commitments win deals that higher bidders lose, particularly with Generac Elite dealer founders who care about what happens to their long-tenured customers.
• MEP-electrical consolidators consistently overpay when they assume the install plus service loop transfers automatically. It does not. The PM attach rate on new installs is a function of the seller’s sales process, technician handoff, and customer relationship management. Buyers who preserve those workflows in year one preserve the multiple they paid.
• Search funds and independent sponsors win in the $500K to $1.5M EBITDA band on speed and continuity. Platform buyers are often slower than they project and in markets where multiple bidders show up, deals in that range frequently go to independent buyers who can close in 90 days and credibly commit to running the business as-is for 24 months.
• State-level nuance matters more than buyers anticipate. Texas (no state contractor license, county-level requirements), Florida (state electrical license plus county standby permit complexity), California (PSPS-driven residential adoption plus Title 24), and the hurricane belt all carry distinct underwriting profiles. Buyers underwriting across states without regional expertise consistently miss on PM pricing and install economics.

If you’re a buyer, here’s what we recommend

Whether you are a first-time search-fund buyer, an independent sponsor building a thesis, or a platform looking for add-ons, the same playbook works in generator service:

1. Write down your thesis in one page. Geography, size, dealer-tier profile, residential vs commercial mix, integration model, hold period. Everything you buy should be defensible against this thesis.
2. Build a deal-flow machine before you need deals. Direct outreach to Generac Premier and Elite dealers in your target geographies, relationships with EGSA chapter leadership, presence at IPM Annual Conference and CONEXPO, and outreach to home-services CPAs and M&A attorneys in the Sunbelt and grid-stressed markets. Proprietary sourcing typically outperforms broker-led processes on price and terms.
3. Underwrite the dealer agreement and the license-holder before the financials. A 9x EBITDA dealer who loses tier status in year one is a 5x EBITDA business. A founder-licensed operation that cannot transfer licensure in 90 days is unsellable. Solve these before you fall in love with the cash flow.
4. Do not mistake price for deal quality. Buyers who pay 7x for a platform-grade Generac plus Kohler dealer with 50%-plus PM attach, EGSA-certified technicians, and a documented install plus service loop typically return capital more reliably than buyers who pay 4x for a founder-dependent install-heavy operator that looks cheap on paper.

Working with CT Acquisitions as a buyer

We maintain a qualified buyer network of generator dealer-rollup platforms, MEP-electrical consolidators, strategic acquirers, family offices, independent sponsors, and search funds. If your thesis fits the deal flow we see, we are direct, fast, and selective about the introductions we make. We do not run broad auction processes. We match founders to the small number of buyers who are right for their specific business.

For buyers, this means: no wasted time on mis-fit deals, early access to deals that have not gone to market, and a sellers-first reputation that founders trust. We are paid by the buyer at close; founders pay nothing.

If you are actively acquiring in generator service, set up a 30-minute conversation to walk us through your thesis. We will be direct about whether our deal flow fits.

Frequently asked questions about buying a generator service business

What EBITDA multiple should I pay when buying a generator service business in 2026?

For platform-grade generator service businesses with 40%-plus PM contract attach, Generac Elite or Cummins or Kohler authorized status, and a documented install plus service plus sell loop, expect competitive bidding in the 6.5x to 9.0x EBITDA range. Residential install-heavy operators with under 25% PM attach typically transact at 3.5x to 4.5x SDE. The factors that move multiples most are PM attach rate, dealer tier, and commercial mix.

How long does it take to close a generator service acquisition?

From initial LOI to close, 90 to 150 days is typical, with OEM dealer consent often the binding constraint. Sophisticated buyers with dedicated diligence teams close at the fast end. Deals with complex license-holder transitions, multi-brand dealer agreements, or real estate components take longer. Generator service deals run 15 to 30 days longer than comparable HVAC deals because of OEM consent timelines.

Should I use an SBA loan when buying a generator service business?

SBA 7(a) works well for independent buyers acquiring generator service businesses up to $5M in purchase price. Rates are favorable (prime plus 2.0% to 2.75%) and the 10-year amortization helps cash flow. Two constraints to flag: the SBA requirement that the seller exit operationally within 12 months can conflict with founder-transition structures, and license-holder transition (the seller is often the named state electrical license holder) needs to be solved before SBA close.

How do I source generator service deal flow if I am new to the category?

The most effective sourcing channels, in order of yield: direct outreach to Generac Premier and Elite dealers identified through the Generac dealer locator and state contractor registries; relationships with home-services and MEP CPAs and M&A attorneys; presence at EGSA (Electrical Generating Systems Association) chapter meetings and the EGSA national conference; relationships with M&A advisors who specialize in the category (CT Acquisitions among them); and broker-listed deals (where you will compete with every other buyer).

What is the biggest mistake first-time buyers make in generator service?

Underestimating the dealer agreement and the license-holder. First-time buyers focus on the cash flow and assume the Generac, Cummins, or Kohler dealer status transfers as a matter of course and that the state electrical license can be quickly reassigned. Neither is true. Dealer agreements require active OEM consent and can be downgraded post-close; license-holder transition can take 90 to 180 days and the business cannot legally operate without it. Solve both before signing.

Can I buy a generator service business with no industry experience?

Yes, but plan for it carefully. The cleanest path for non-operators is acquiring a business with a strong general manager and credentialed license-holder in place and structuring a transition period where the founder stays 12 to 24 months. Generator service is more technically demanding than HVAC for an absentee owner because of OEM tier requirements and high-voltage safety culture. Avoid the absentee-owner thesis; integrated install-service operators deteriorate quickly under inattentive ownership.

How much working capital do I need to close a generator service deal?

For a $3M EBITDA generator service business, expect to fund 10% to 15% of revenue in working capital at close (receivables, parts inventory, job-in-progress, and any committed Generac or Cummins inventory). That is typically $1M to $2M on top of the purchase price. Parts inventory tends to be heavier than HVAC because OEM-specific parts are not cross-compatible and dealers maintain stocking commitments. Financing structures usually fold this into the facility; confirm with your lender before committing.
