What SDE multiple do HVAC businesses trade at in Q1 2026?

US small-business HVAC acquisitions traded in a 2.8×–5.0× SDE band over the trailing twelve months ending April 2026 (n=123). Band placement is structural: deal size, OEM dealer status (Carrier FAD, Trane TCS, Lennox Premier), W-2 master license depth, and AOR attach rate determine where a specific deal sits.

How does the IRA credit termination affect 2024–2025 trailing revenue?

IRS Section 25C and 25D credits terminated for property placed in service after December 31, 2025 under P.L. 119-21 (OBBB). Trailing-period install revenue concentrated in 2024–2025 reflects pull-forward demand that will not repeat. When heat pump installation share exceeds 40% of trailing installs, normalization typically reduces presented SDE by 12–22%. Manufacturer warranty registration data is the most reliable third-party verification.

What is a 1099 Qualifier and why does SBA flag it?

A 1099 Qualifier is a non-employee licensed master receiving a monthly retainer ($500–$2,500 typical) to serve as the entity's named license holder for state regulatory purposes. The arrangement appeared in 38% of Q1 2026 deals reviewed. SBA underwriters increasingly treat this structure as failed license continuity at change of ownership — the Qualifier is not a transferable employee asset and may not survive transaction close.

What is the AIM Act R-410A phase-down impact on inventory value?

Under EPA 40 CFR Part 84, residential and light commercial AC equipment manufactured for sale moved to A2L-class refrigerants (R-32, R-454B) beginning January 1, 2025, with field-assembled equipment subject to additional restrictions effective January 1, 2026. R-410A field-van and warehouse inventory held at acquisition is depreciating against A2L-ready stock; equipment value haircut typical in 31% of deals with material field inventory.

What is AOR attach rate and what is a healthy benchmark?

AOR (Agreement on Repair) attach rate measures the percentage of service repair calls converted to a Comfort Club / maintenance agreement during the call. Observed band is 20%–45% across the sample window. Above 35% indicates organic upselling discipline and supports top-third band placement on the Pricing pillar.

Which states allow non-employee Qualifier license arrangements?

Arizona explicitly permits a non-employee qualifying party under ARS 32-1122 with bonding requirements. Texas TDLR ACR rules are statutorily ambiguous on Qualifier employment status. Florida (DBPR), California (CSLB RME), Georgia (CILB), and North Carolina require the qualifying agent to be a bona fide officer or full-time employee. Verify state-by-state before LOI; SBA lender treatment is increasingly stricter than state minimums.

What is the difference between Comfort Club and PM-only service agreements?

Comfort Club agreements typically bundle two annual maintenance visits with priority dispatch, repair discounts, and an AOR pathway — generating 45%–55% gross margin and feeding the AOR pipeline. PM-only (planned maintenance) agreements cover scheduled visits without the bundled benefits and generate lower attach rates. Cohort-level retention data on Comfort Club (vs blended agreement count) is the Earnings Quality pillar marker.

How do manufacturer dealer programs (Carrier FAD, Trane TCS, Lennox Premier) transfer at change of ownership?

OEM dealer status is typically held by the entity, but renewal at change of ownership requires re-qualification — covering technician training currency, warranty registration history, and customer satisfaction metrics. Status held in the owner's personal name (rather than the entity) is the highest-risk transfer scenario. Verify status at the entity level and confirm OEM transfer policy directly with the manufacturer rep before pricing top-of-band.

Q1 2026 · The Read

US small-business HVAC acquisitions traded in a 2.8×–5.0× SDE band over the trailing twelve months (n=123). Band dispersion is structural — placement runs on deal size, dealer status, and W-2 license depth, not market timing.

The four-pillar read across Q1 deals: Earnings Quality compressed by IRA pull-forward in 47% of reviews; Pricing top-of-band locked to FAD/TCS/Premier dealer status and W-2 master license depth; Fundability fall-through driven by 1099 Qualifier arrangements ahead of DSCR failure; Transferability bottom-of-band in deals without a Comfort Club cohort and with owner-dependent Comfort Advisor function.

The structural trap: presented SDE without IRA normalization overstates steady-state earnings by 12–22% in pull-forward deals. IRA 25C/25D terminated December 31, 2025 under P.L. 119-21.

Executive summary

Four findings shaping Q1 2026 HVAC deal flow.

Principal finding

IRA 25C and 25D federal tax credits expired December 31, 2025 under P.L. 119-21. Every deal with trailing periods touching 2024–2025 contains confirmed pull-forward demand concentrated in heat pump installations. Normalization is required when heat pump revenue share exceeds 40% of trailing installations — typically reducing presented SDE by 12–22%.

Further findings

02
Finding 02
The 1099 Qualifier arrangement — a non-employee licensed master receiving $500–$2,500/month to serve as the entity's named license holder — appeared in 38% of deals reviewed. SBA underwriters are increasingly treating this structure as failed license continuity, driving fall-through before DSCR analysis is even reached.
03
Finding 03
Comfort Advisor function replacement cost (the in-home sales and diagnostic role typically performed by the owner) was excluded from owner add-backs in 45% of deals. This is the most common post-LOI repricing trigger — replacement cost runs $65,000–$110,000 fully loaded in most markets.
04
Finding 04
AIM Act R-410A refrigerant transition (effective January 1, 2025) created stranded inventory risk in 31% of deals with field-van stock. Pre-transition R-410A equipment held in inventory is depreciating rapidly and requires a haircut to equipment value in band-placement analysis.

Section 01 · Industry Snapshot

A $135B services market, fragmented at the SMB level.

A $135B services market growing 2–4% annually, but 87% of installed base sits with sub-$10M contractors. Acquisition opportunity is structurally durable — fragmentation has not compressed despite a decade of PE roll-up — but scale alone does not earn top-of-band placement.

What it means

For the buyer

Multiple expansion will not come from sector tailwind — only structural quality (license depth, recurring share, dealer status) earns up-band placement.

For the broker

Sub-$1M SDE listings trade at the bottom of the band regardless of presented margin; size narrative will not move a buyer pool that prices on structure.

For the lender

Sector-level credit risk is benign — fragmentation is the fall-through driver, not industry cyclicality, so underwrite operator-level continuity.

For the seller

Path to upper-band placement is operator-quality positioning ahead of listing; waiting for a market cycle is not a strategy in a 2–4% growth sector.

Section 02 · Industry Structure

How demand and friction shape the competitive forces.

Climate intensity, electrification, and aging stock are the three durable tailwinds — none cyclical, none policy-dependent post-IRA. Against them sit refrigerant transition cost, technician scarcity, and post-IRA demand normalization. The competitive structure that emerges: a high-rivalry, mid-supplier-power industry where structural friction concentrates at supplier dealer programs and the technician labor pool, not at customer acquisition.

Competitive forces — HVAC, Q1 2026
Force	Pressure	Read
Rivalry among operators	high	Aging US housing stock and the refrigerant-transition replacement cycle keep residential demand structurally elevated, which draws PE-backed consolidator activity into dense metros and compresses density-driven margins. Customer switching cost is low on residential service calls; no single national share leader exists at the service level. The NATE-certified technician shortage caps the pace at which any one operator can absorb that demand, keeping rivalry fragmented.
Supplier power	high	OEM concentration (Carrier, Trane, Lennox, Daikin, Goodman/Daikin) controls dealer programs that gate access to top-tier residential pricing. The R-410A → A2L refrigerant transition under the AIM Act compounds supplier leverage on two fronts — R-410A scarcity through phase-down, and A2L ramp constraints on the new chemistry — creating short-term supplier-side power that connects directly to the stranded-inventory headwind.
Buyer power	medium	Residential customers transact one-off and have low individual leverage; demand from aging housing stock keeps them price-takers. Light commercial accounts (property managers, multi-site owners) carry meaningful negotiating power on planned-maintenance contracts and RTU rollouts. State-level electrification policy shifts some cooperative buying power to utility/code-driven channels in CA, NY, MA, WA.
Threat of new entry	medium	Master HVAC license requirements, fleet and inventory capital ($500K+ to operate at minimum scale), and EPA Section 608 certification create entry friction. The 1099 Qualifier license-portability headwind has tightened — non-employee Qualifier arrangements now flag under SBA underwriting at change of ownership, raising the practical bar to entry via acquisition. Offsetting this, no economies-of-scale block exists at the small-shop level — sole-operator entry remains feasible in most states.
Threat of substitutes	low	Heat pumps substitute for boiler/oil heat in certain regional markets — the structural electrification tailwind — but no true substitute exists for HVAC service in cooling-load climates, where climate-driven cooling intensity is rising. Adjacent trades (plumbing, electrical) cannot service refrigerant systems without 608 certification.

What's enforced today, what's coming, and where the state-by-state friction sits.

Two federal regimes (EPA 608, AIM Act) and a 22-state license matrix together set the floor on operator-quality friction. The binding question for Q1 2026 deals is no longer compliance status — it is whether trailing-period margins were earned with R-410A inventory now stranded under the AIM Act phasedown, and whether the master license travels with the entity.

North Carolina	NC Board of Examiners H-1/H-2/H-3	$120/yr	Qualifier must be full-time and active in business operations

What it means

For the buyer

Deals with a 1099 Qualifier license structure carry a structural Fundability discount independent of SDE quality — discount the price or pass.

For the broker

Pre-listing license-transfer planning recovers more multiple than any add-back argument; surface license structure in the CIM, not in due diligence.

For the lender

Lender-continuity risk is the dominant Q2 SBA fall-through cause (62%) — confirm W-2 master license attached to entity before issuing terms.

For the seller

Move the master license to a W-2 employee or transfer it to the entity at least two quarters before listing, otherwise expect a Fundability haircut.

Section 04 · Labor & Unit Economics

Where the labor cost lives, and what each service line actually earns.

Direct labor is 38–44% of revenue in service-dominant operators; tech turnover 22–28%/yr; the structurally scarce role is the senior service tech with 608 Universal certification. Margin compression in 2026 is a labor story, not a parts story — wage inflation (6–9% in tight metros) is outpacing service-call price increases.

Industry technician turnover ~22% annually (ACCA); top quartile achieves 8–12% via tenure-tied bonus. NATE certification (Specialist → Senior) and OEM training (Carrier University, Trane Technical Institute, Lennox LearningHub) gate top-tier dealer pricing.

HVAC values from this Atlas. Plumbing, Electrical, and Roofing values are indicative trailing-12-month bands from BizBuySell / Sundance composite samples and Acquidex direct deal observations; full peer Atlases ship Q3 2026 onward.

What it means

For the buyer

Targets retaining a multi-year senior-tech bench earn a Transferability premium; turnover above the 28% ceiling priced as a post-close labor-rebuild discount.

For the broker

Lead the buyer with tenure data and 608 Universal coverage; service-call price is a weaker selling point in 2026 than the technician retention story.

For the lender

Confirm 608 Universal certifications are W-2 (not 1099) and tied to the entity; re-cut wage assumptions at trailing-12-month inflation before sizing DSCR.

For the seller

A documented training pipeline (apprenticeship, 608 prep, AOR protocols) is the single highest-ROI Transferability signal — and the slowest to build.

Section 05 · Geographic distribution

Demand intensity, competitive density, and which acquirer pool each metro favors.

Acquirer pool composition — not headline metro size — sets the realistic exit. Sun Belt metros (DFW, Phoenix, Tampa) are dominated by PE-platform competition where searcher offers are typically outbid; secondary metros (Indianapolis, Raleigh-Durham) remain searcher-accessible with intact independent baselines. Targeting follows the acquirer pool match, not the demand ranking.

HVAC demand intensity is climate-driven; profitability is driven by technician availability and market density. The Acquisition Read column inverts competition density into the structural opportunity it implies — mature markets favor strategic add-ons, mid-stage markets favor platform builders, less-saturated markets favor individual searchers.

Metro	Demand	Competition	Acquisition Read
Phoenix, AZAZ ROC CR-39; A2L training penetration above national avg	CDD ~4,500 / yr	High multiple PE-backed consolidators active	PE roll-up territory
Houston, TXTDLR ACR; Qualifier employment ambiguity flagged in SBA review	CDD ~3,000 / yr	High large independent base + national strategics	Strategic acquirer market
Dallas–Fort Worth, TXTDLR ACR; FAD dealer density above national average	CDD ~2,800 / yr	High dense consolidator footprint	PE roll-up territory
Atlanta, GACILB Conditioned Air I/II; full-time Qualifier required	CDD ~1,900 / yr	Medium-high Apex and ARS active	Active consolidation
Tampa–St. Petersburg, FLDBPR Class A/B; W-2 Qualifier statutory requirement	CDD ~3,400 / yr	Medium-high strategic + searcher activity	Mixed pool · searcher accessible
Orlando, FLDBPR Class A/B; W-2 Qualifier required	CDD ~3,200 / yr	High strategic + PE platform activity	Multi-acquirer competition

What it means

For the buyer

Identical operating profiles trade 0.5–1.0× higher in PE-saturated metros than in independent-base metros, but only when size matches platform tuck-in criteria.

For the broker

Match the listing process to the acquirer pool that actually clears in the metro; a national process in a PE-saturated market filters out the highest bidder.

For the lender

Confirm which acquirer pool actually closed the last five comparable transactions before underwriting comp-derived value — pool composition determines comp validity.

For the seller

List where your pool shops; metro choice and process design move multiple more than another quarter of trailing-period polish.

Section 06 · Buyer Pool

Five acquirer categories, with public closed-deal record.

Five distinct acquirer categories — PE platforms (Apex, Wrench Group, Service Logic), strategic add-ons, search funds, family offices, and independent operators — each price the same target differently because they capitalize different parts of the four-pillar profile. Identifying the matching pool before listing is the highest-leverage exit decision a seller controls.

Strategic acquirers

National service platforms with operational infrastructure to absorb add-ons. Typical bid posture: top-of-band for FAD/TCS/Premier dealers with W-2 license depth.

Examples · ARS / Rescue Rooter (American Residential Services) · Apex Service Partners · Service Logic

Recent closed deals · public

2024-09Apex Service Partners acquired Service Champions Heating & Air (Bay Area) · Apex Service Partners press release
2024–2025ARS / Rescue Rooter acquired Multiple regional add-ons (TX, FL) · ARS press releases

PE platforms

Sponsor-backed roll-up vehicles. Bid through platform CEOs; diligence rigor highest of the buyer-pool categories. Increasingly sensitive to IRA pull-forward normalization.

Examples · Wind Point Partners (Service Logic) · Sterling Investment Partners · Linsalata Capital Partners · Authority Brands (One Hour Heating & Air)

Recent closed deals · public

2024–2025Authority Brands acquired One Hour Heating & Air Conditioning (continued add-on activity)· Multiple · Authority Brands news
2024Linsalata Capital Partners acquired HVAC platform investment (regional) · Linsalata portfolio

Regional consolidators

Sub-platform acquirers operating in 1–3 states. Often franchise-affiliated. Bid posture mid-band; prefer sub-$1M SDE targets within their existing service radius.

Examples · Sila Heating & Air · One Hour Heating & Air (Authority Brands) · HomeServices of America platforms

Recent closed deals · public

2023Sila Heating & Air acquired Bornstein Sons (Northeast HVAC, Fairfield NJ) · Sila Services news
2024–2025One Hour Heating & Air acquired Multiple franchise-territory rollups

Individual searchers (SBA-financed)

Self-funded or search-fund buyers using SBA 7(a) leverage. Typical target: $300K–$1M SDE, regional focus, 0.5–1.5 FTE buyer team. Most sensitive to Qualifier license structure.

Examples · Self-funded searchers · ETA / search-fund operators · First-time SBA buyers

Disclosure note

Individual-searcher closed-deal data is not consistently disclosed publicly — most SBA 7(a) acquisitions are private and tracked only through Searchfunder, ETA forums, or post-close LinkedIn announcements. Aggregate volume tracked through SBA 7(a) lender data; individual transactions not reproduced here without seller consent.

Family offices

Patient capital with longer hold periods. Less platform-driven; often partner with operating GP. Bid posture mid-to-upper band when fit is right; willing to accept lower IRR for stable cash flow.

Examples · Single-family offices with HVAC platform thesis · Multi-family office operating-partner vehicles

Disclosure note

Family-office HVAC transactions are predominantly off-market and unannounced. Public deal records exist only where the family office has registered as an LP in a sponsor-led fund or where the operating partner discloses voluntarily. Aggregate activity not reproduced at the transaction level.

What it means

For the buyer

Know which pillars your category prices on — searchers underwrite Fundability, PE platforms underwrite Transferability, strategics underwrite dealer status.

For the broker

Structure the data room around the pool you intend to attract; broadening the process to all five pools dilutes the pillar emphasis that earns the multiple.

For the lender

Pool composition flags credit risk — searcher-bound deals carry SBA-continuity risk; PE-bound deals carry rollover-equity and post-close labor risk.

For the seller

Lead with pool-specific positioning (e.g. dealer status for strategic add-ons; recurring revenue for PE) rather than a generic CIM aimed at everyone.

Section 08 · Top 3 Pre-LOI Diligence Items

The three highest-stakes verifications before a letter of intent.

Verify the master license is W-2 and attached to the entity

Why:The 1099 Qualifier arrangement is the dominant Q2 SBA fall-through cause (62%); SBA underwriters are treating it as failed license continuity before reaching DSCR.

Check:State licensing portal lookup · payroll register showing the master as a W-2 employee · entity-named licenses on file · no $500–$2,500/month consulting payments to outside individuals.

critical

Fundability

Normalize trailing-period SDE for IRA 25C/25D pull-forward

Why:IRA credits expired Dec 31, 2025 (P.L. 119-21). Deals with heat pump revenue share above 40% in 2024–2025 carry confirmed pull-forward — presented SDE typically overstates steady-state earnings by 12–22%.

Check:Heat pump unit sales by month 2023–2025 · manufacturer warranty registration data · install vs service revenue mix · post-Jan 2026 monthly install run-rate.

critical

Earnings Quality

Re-cut gross margin at A2L refrigerant cost basis

Why:AIM Act transition (effective Jan 1, 2025) is depreciating R-410A field-van inventory in 31% of deals; trailing margins blended across the transition overstate forward economics.

Check:Field-van and warehouse inventory list with ship-date by SKU · A2L (R-32, R-454B) vs R-410A unit-cost differential · A2L technician certification roster.

AQX Evaluation Layer · Section 11 · Cross-Border Lens · US / Japan

How the band reads under J-GAAP and prefectural licensing.

Japanese HVAC (空調設備) businesses operate at compressed multiples of 2.0×–3.5× EBITDA under J-GAAP, driven by mandatory goodwill amortization over 20 years, tighter technician licensing portability between prefectures, and smaller average deal size. Daikin and Mitsubishi dealer networks dominate market structure in Japan, and manufacturer dealer agreements are typically tied to the controlling entity — not the individual owner — making transfer somewhat cleaner than US OEM arrangements.

Dimension	United StatesUSD · US GAAP	JapanJPY · J-GAAP
Multiple band	2.8×–5.0× SDE	2.0×–3.5× EBITDACross-border discount of ~30–40% reflects accounting + buyer-pool structural friction
Accounting standard	US GAAP; goodwill held at carrying value, impairment-tested	J-GAAP; mandatory goodwill amortization over 20 yearsJP amortization mechanically suppresses post-deal earnings — direct multiple compressor
Refrigerant regime	EPA AIM Act phase-down; A2L (R-32, R-454B) for new equipment from Jan 2025	METI / 改正フロン排出抑制法; R-32 mainstream since 2014, A2L familiarity highJP technicians ~10 years ahead on A2L handling; lower training-capex transition cost
Technician licensing	State-by-state master license; 1099 Qualifier arrangements common in TX/FL/AZ/GA	冷凍空調技士 / 高圧ガス製造保安責任者 — national certs portable across prefecturesJP license portability removes a structural transferability risk that compresses US lower-band
OEM dealer programs	Carrier FAD / Trane TCS / Lennox Premier — entity-tied but re-evaluated at change of ownership	Daikin / Mitsubishi dealer agreements typically held by the controlling entityJP entity-tied agreements transfer more cleanly than US OEM re-application requirement
Tax-credit pull-forward	IRA 25C/25D terminated Dec 31 2025 (P.L. 119-21); 2024–2025 install revenue inflated	No equivalent federal credit; 補助金 prefecture-level subsidies modest, not pull-forward driverJP install revenue closer to steady-state; US trailing-period normalization not required for JP comps
Buyer pool	PE platforms + strategic acquirers + ETA / SBA-financed individual searchers	Domestic strategic + 事業承継 (succession) brokers; limited foreign-buyer infrastructureJP cross-border buyer pool thinner — discount partly reflects exit-liquidity risk

Synthesis · the contrast in three lines

01Apply a 0.5×–1.0× discount to Japanese HVAC SDE/EBITDA when comparing to US bands; J-GAAP goodwill amortization explains roughly half of the gap.
02A2L refrigerant transition is a US-vintage cost and risk; Japanese technicians have handled R-32 since 2014. Cross-border buyers should price this as a US-side haircut, not a Japanese-side opportunity premium.
03OEM dealer-status mechanics are structurally different — Japanese Tokuyakuten (特約店) agreements are entity-issued (cleaner than US OEM transfer) but reassignment requires explicit OEM consent on a 60–90 day timeline; loss of partner status compresses EBITDA by 200–400 bps via lost rebates (5–10% of installation revenue, 2–5% of maintenance).
04JP technician scarcity is the binding structural constraint: only ~15,000 active 冷凍機械責任者 (Refrigerating Machine Engineer) certifications exist nationwide (JIRFE, 2024). Tokyo loaded labor cost runs ¥7–10M per technician; key-tech departure post-close has been documented to cause 50–70% EBITDA contraction within 2–4 weeks via refrigerant-handling registration suspension.
05METI / MOE field surveys (2018–2022) found >60% of fluorocarbon refrigerants remained in disposed AC equipment, indicating systemic non-compliance with the Fluorocarbon Emissions Suppression Act (フロン排出抑制法). Penalties of ¥500K–¥1M per violation plus 5-year record retention make pre-LOI audit of refrigerant logbooks the single highest-stakes JP-side diligence step.
06Aggregate regulatory compliance cost on a ¥500M revenue contractor runs ¥30–50M annually (6–10% of revenue) across recovery certification, Construction Business Act licensing, insurance, and Building Standards Act audits — JP regulatory friction is materially higher than the US equivalent and is the structural reason JP HVAC trades at compressed multiples beyond what J-GAAP alone explains.

HVAC buyer questions.

Q01What SDE multiple do HVAC businesses trade at in Q1 2026?+
US small-business HVAC acquisitions traded in a 2.8×–5.0× SDE band over the trailing twelve months ending April 2026 (n=123). Band placement is structural: deal size, OEM dealer status (Carrier FAD, Trane TCS, Lennox Premier), W-2 master license depth, and AOR attach rate determine where a specific deal sits.
Q02How does the IRA credit termination affect 2024–2025 trailing revenue?+
IRS Section 25C and 25D credits terminated for property placed in service after December 31, 2025 under P.L. 119-21 (OBBB). Trailing-period install revenue concentrated in 2024–2025 reflects pull-forward demand that will not repeat. When heat pump installation share exceeds 40% of trailing installs, normalization typically reduces presented SDE by 12–22%. Manufacturer warranty registration data is the most reliable third-party verification.
Q03What is a 1099 Qualifier and why does SBA flag it?+
A 1099 Qualifier is a non-employee licensed master receiving a monthly retainer ($500–$2,500 typical) to serve as the entity's named license holder for state regulatory purposes. The arrangement appeared in 38% of Q1 2026 deals reviewed. SBA underwriters increasingly treat this structure as failed license continuity at change of ownership — the Qualifier is not a transferable employee asset and may not survive transaction close.
Q04What is the AIM Act R-410A phase-down impact on inventory value?+
Under EPA 40 CFR Part 84, residential and light commercial AC equipment manufactured for sale moved to A2L-class refrigerants (R-32, R-454B) beginning January 1, 2025, with field-assembled equipment subject to additional restrictions effective January 1, 2026. R-410A field-van and warehouse inventory held at acquisition is depreciating against A2L-ready stock; equipment value haircut typical in 31% of deals with material field inventory.
Q05What is AOR attach rate and what is a healthy benchmark?+
AOR (Agreement on Repair) attach rate measures the percentage of service repair calls converted to a Comfort Club / maintenance agreement during the call. Observed band is 20%–45% across the sample window. Above 35% indicates organic upselling discipline and supports top-third band placement on the Pricing pillar.
Q06Which states allow non-employee Qualifier license arrangements?+
Arizona explicitly permits a non-employee qualifying party under ARS 32-1122 with bonding requirements. Texas TDLR ACR rules are statutorily ambiguous on Qualifier employment status. Florida (DBPR), California (CSLB RME), Georgia (CILB), and North Carolina require the qualifying agent to be a bona fide officer or full-time employee. Verify state-by-state before LOI; SBA lender treatment is increasingly stricter than state minimums.
Q07What is the difference between Comfort Club and PM-only service agreements?+
Comfort Club agreements typically bundle two annual maintenance visits with priority dispatch, repair discounts, and an AOR pathway — generating 45%–55% gross margin and feeding the AOR pipeline. PM-only (planned maintenance) agreements cover scheduled visits without the bundled benefits and generate lower attach rates. Cohort-level retention data on Comfort Club (vs blended agreement count) is the Earnings Quality pillar marker.
Q08How do manufacturer dealer programs (Carrier FAD, Trane TCS, Lennox Premier) transfer at change of ownership?+
OEM dealer status is typically held by the entity, but renewal at change of ownership requires re-qualification — covering technician training currency, warranty registration history, and customer satisfaction metrics. Status held in the owner's personal name (rather than the entity) is the highest-risk transfer scenario. Verify status at the entity level and confirm OEM transfer policy directly with the manufacturer rep before pricing top-of-band.

§3.4 (Earnings Quality), §3.3 (Transferability), §5.1 (Add-Back Stripping per SBA SOP 50 10 8)

Scope

SMB and lower-middle-market HVAC acquisitions in the US and Japan. The 2.8×–5.0× SDE band reported here covers transactions roughly $200K–$5M SDE (sub-$10M EBITDA enterprise value); larger-platform M&A operates on different mechanics (Q-of-E, working-capital pegs, R&W insurance) and is out of this Atlas's scope.

Sample window

2025-05 → 2026-04 (trailing 12 months)

Sample composition

N = 47 transactions. Acquidex direct deal observations during the trailing 12-month sample window (2025-05 → 2026-04). Sample composition: 47 HVAC service-business transactions reviewed across buyer engagements, lender pre-qualification consultations, broker-package extracts, and anonymized post-LOI repricing memos. Geographic skew toward Sun Belt and Midwest secondary metros; revenue range $750K–$5M; mix of service-dominant and install-dominant operators; both 1099 Qualifier and W-2 master-licensed structures represented.

Operator-curated, not statistically random. Sample reflects deals an active acquisitions practitioner observed during the period — selection is a function of what crossed Acquidex's desk, not a representative cross-section of the US HVAC SMB market. Percentages cited reflect occurrence rates within this sample only and should not be interpreted as market-wide point estimates. Confidence on each percentage: medium (operator-curated direct observation; structural patterns consistent with broader broker-package extracts cited in sourcesList).
