Best National HVAC Franchise Brands with Standardized Warranty Backed Installs (2026)

The research in brief

One Hour Heating & Air Conditioning is the consensus leader for homeowners who want a recognized national HVAC franchise with written warranty language and a formal satisfaction-accountability path, named by all 7 platforms studied. Aire Serv is the strongest alternative for buyers who want a written workmanship re-performance promise and a Neighborly network affiliation, while Service Experts is the best fit for buyers who want a multi-location provider with a written one-year installation-performance guarantee and optional bundled maintenance or lease-style coverage. The study sent one standardized prompt once to each of 7 AI platforms and consolidated 28 unique entities, of which only 3 were named by at least two platforms. The principal limitation is that all three brands are franchise or multi-location networks whose actual warranty terms, pricing, and execution vary by local operator, so platform consensus reflects brand-level promises rather than verified local delivery.

Which provider fits your needs?

Questions explored

• Which national HVAC franchise brand should a homeowner choose if written warranty documentation and a formal escalation path matter most?
• Is Aire Serv or Service Experts better for a homeowner who wants a written installation-performance guarantee rather than a satisfaction promise?
• Which national HVAC franchise brand is best for a homeowner who wants bundled maintenance or lease-style coverage instead of an outright purchase?

1. One Hour Heating & Air Conditioning

Questions explored

• Is One Hour Heating & Air Conditioning worth it for national franchise warranty backed installs, and what are its main drawbacks?
• Does One Hour Heating & Air Conditioning register equipment for the manufacturer parts warranty, and what happens if registration is missed?
• Is the One Hour Heating & Air Conditioning warranty transferable if I sell my home?

One Hour Heating & Air Conditioning is the consensus leader for this use case and the only entity named by all seven platforms. It combines a recognizable national franchise brand, a published two-year materials, labor, and craftsmanship guarantee, the UWIN satisfaction-accountability program, an on-time guarantee, and StraightForward Pricing ^[42]. The fit is good but not uniform: locations are independently owned and operated, so the installing entity, contract, licensing, pricing, and practical warranty administration are generally the local franchise's responsibility rather than a single centrally operated national installer ^[41].

The complete fit review is available here: One Hour Heating & Air Conditioning.

Why it ranked here. One Hour received first-place rankings from five of seven platforms and third-place rankings from the remaining two, producing the lowest average listed position (1.57) in the study. Platforms consistently cited the same three brand-level assets: national scale, written guarantee language, and the UWIN escalation mechanism. Authority Brands reports more than 410 U.S. territories, and platform-reported sources describe 400+ locations with concentration in the Southeast and Southwest ^[35].

Best suited for. Homeowners who value a national brand, local availability, written warranty documentation, and a formal escalation path more than the lowest installation price; replacement buyers who will obtain and compare the local franchise's complete written labor, equipment, registration, maintenance, and satisfaction terms before signing; and buyers who want an independently operated local contractor combined with One Hour branding and UWIN accountability ^[35].

Main strengths for the use case. The brand publishes a two-year guarantee covering materials, labor, and craftsmanship from the service date, and UWIN is described as a consumer service resource that backs the satisfaction guarantee and provides an escalation path when a local office does not resolve a concern ^[42]. Google's evidence describes UWIN as a standardized three-step dispute resolution process involving a corporate team if the local franchise fails to resolve an issue ^[9]. The on-time guarantee states that if a technician misses the predetermined arrival window, the service call is free ^[42]. StraightForward Pricing presents costs before work begins ^[6]. Aggregate review data reported by Claude shows 4.82 stars across 202,185 Google reviews ^[42].

Main limitations. Independent franchise ownership can produce variation in installation quality, staffing, equipment brands, pricing, and warranty administration ^[41]. Anthropic's evidence documents BBB ratings ranging from 1.72/5 at a Tampa, Florida location to 4.97/5 at an Avon, Ohio location, and customer complaints citing missed appointments despite the on-time guarantee, delayed warranty claim processing, and misdiagnosis requiring repeat visits ^[94]. Manufacturer parts registration is a specific gap: complaint evidence indicates franchises have failed to register equipment within the required 60-90 day window, causing coverage to drop from 10 years to 5 years ^[104]. The warranty is described as non-transferable in reviewed local terms ^[43]. Warranty work performed outside regular business hours may be subject to after-hours charges, and repairs require pre-approval and inspection by One Hour ^[51]. No uniform nationwide 10-year parts-and-labor warranty or national installation price was verified ^[46].

Pricing or cost summary. No national installation price list was found. Installation pricing, equipment selection, financing, labor coverage, maintenance requirements, and cancellation terms are local-franchise proposal terms ^[42]. Google's evidence reports diagnostic fees typically ranging from $79 to over $100 depending on the branch ^[92]. Anthropic's evidence cites customer-reported diagnostic and trip fees in a $160-$560+ range and notes industry-average HVAC installation of $5,000-$12,000, with One Hour pricing reported as "on the higher side" in some markets ^[94]. Kimi reports a franchisee cost structure of $146K-$285K total investment with a $60K franchise fee and 6.0% ongoing royalty, which may influence local pricing but does not directly dictate consumer-facing warranty terms ^[84]. Pricing confidence across platforms is low.

Where platforms disagreed. Fit ratings ranged from "strong" (Grok) to "good" (ChatGPT, Claude, Gemini, Perplexity) to "mixed" (DeepSeek, Kimi) ^[7]. Deepseek and Perplexity both reference a published 10-year parts-and-labor option in some markets, while ChatGPT, Claude, and Kimi state that no standardized 10-year parts-and-labor offer was verified across the network ^[10]. The official domain is also unresolved: the supplied domain onehourheating.com timed out during research, and accessible consumer pages were retrieved on onehourheatandair.com, so the domain identity and redirect relationship remain unverified ^[128].

2. Aire Serv

Questions explored

• Is Aire Serv worth it for national franchise warranty backed installs, and what are its main drawbacks?
• Does the Neighborly Done Right Promise cover HVAC equipment and parts, or only Aire Serv's own workmanship?
• Which national HVAC franchise brand should a homeowner choose if they want to supply their own thermostat or equipment?

Aire Serv is the strongest alternative for buyers who want a national franchise brand with a written workmanship promise and a larger multi-brand home-services network behind the local installer. It is a good but qualified fit: the Neighborly Done Right Promise is primarily a limited re-performance commitment for services, not a comprehensive national parts, equipment, or labor warranty ^[38]. The complete fit review is available here: Aire Serv.

Why it ranked here. Aire Serv was named by five of seven platforms and ranked second by four of them, producing an average listed position of 2.20. Platforms cited the Neighborly affiliation, a 200+ location network, upfront job-based pricing, and the Done Right Promise as the core reasons for inclusion ^[16].

Best suited for. Homeowners who value a recognizable HVAC franchise brand, upfront job pricing, and documented workmanship accountability; buyers who want a local installer connected to a larger Neighborly franchise network; and routine residential HVAC replacement or installation where the local franchise provides the needed equipment, permits, and post-installation support ^[16].

Main strengths for the use case. The Done Right Promise requires the customer to contact the local franchise within 60 days if the service was not done right, and the local franchise will re-perform the services at no additional cost, subject to exclusions ^[38]. Anthropic's evidence describes additional system-level guarantees advertised for installations, including a full-coverage guarantee, a temperature guarantee, a 12-month satisfaction guarantee, and compressor or heat exchanger failure coverage, with system assurance coverage cited as ranging from 12 months to 10 years depending on the system chosen ^[122]. Aire Serv advertises 24/7 emergency service with no overtime surcharge for nights and weekends ^[91]. The brand advertises guaranteed upfront job-based pricing with no hidden fees ^[37]. The Advantage Plan is a membership program offering priority service and seasonal checks, and Claude's evidence states Advantage Plans do not expire ^[28].

Main limitations. The published Done Right Promise states that Aire Serv provides a service promise and disclaims warranties from Aire Serv or its franchise owners for third-party manufactured materials or goods installed with the service, except where otherwise provided ^[38]. The promise excludes manufacturer or product defects, acts of nature, customer or third-party acts, latent property defects, and unpaid services ^[38]. The 60-day claim window may be short for latent installation or equipment problems ^[38]. No verified national guarantee was found requiring another Aire Serv franchise to honor or administer a warranty if the original franchise closes, changes ownership, or is outside the homeowner's area ^[38]. Aire Serv maintains a strict policy of only installing HVAC systems, thermostats, and accessories it furnishes directly, refusing to warranty customer-supplied products ^[19]. Kimi reports that Aire Serv was the only major Neighborly home services brand with declining unit count (-1% over three years), signaling potential territory saturation, and cites a 7% royalty plus marketing fees totaling roughly 11% of revenue ^[126]. Independent review evidence documents franchise-level variability in service quality, scheduling, and communication ^[78].

Pricing or cost summary. No nationally standardized residential HVAC installation price was verified. Aire Serv advertises job-based upfront pricing, but actual price depends on the local franchise, equipment, system size, ductwork, permits, electrical work, refrigerant requirements, and other project conditions ^[37]. Grok's evidence cites promotional discounts such as $500 off new system installation at participating locations ^[14]. Kimi reports a franchise fee of $45,000 with 7% ongoing royalty and roughly 11% combined brand and marketing fees, which influence local pricing but are not direct consumer prices ^[126]. Perplexity's evidence notes one local page stating many systems come with a 12-year parts warranty and an optional free 12-year labor warranty tied to an active maintenance agreement, and other local pages stating replacement-system coverage ranging from 12 months to 10 years depending on the system chosen ^[20]. Pricing confidence across platforms is low.

Where platforms disagreed. Fit ratings ranged from "good" (ChatGPT, Claude, Gemini, Grok, Perplexity) to "mixed" (DeepSeek, Kimi) ^[16]. The Done Right Promise term is reported inconsistently: most current sources state 60 days, while older company materials and some location pages state one year, and Perplexity explicitly flags this conflict ^[38]. Location counts also conflict: Aire Serv's public materials describe more than 200 locations, the live location directory displayed 254 when checked, and Kimi cites 175+ locations across multiple countries ^[16]. Deepseek notes that the official site could not be retrieved during ranking, so standardization claims are company-stated rather than independently verified ^[1].

3. Service Experts

Questions explored

• Is Service Experts worth it for national franchise warranty backed installs, and what are its main drawbacks?
• Is the Service Experts Advantage Program a purchase or a lease, and what happens if I terminate early?
• Which national HVAC franchise brand should a homeowner choose if they want a written one-year installation-performance guarantee with defined repair attempts?

Service Experts is the best fit among the three for buyers who want a written one-year installation-performance guarantee with defined repair attempts and an optional bundled maintenance or lease-style coverage model. It is a good fit with meaningful caveats: coverage is concentrated in listed markets, services and pricing vary by location, and the core installation guarantee is limited, conditional, and tied to the contracting Service Experts entity and service order ^[52]. The complete fit review is available here: Service Experts.

Why it ranked here. Service Experts was named by four of seven platforms and received the widest rank spread in the study: first from Claude, second from ChatGPT, and third from Grok and Perplexity, producing an average listed position of 2.25 ^[111]. Platforms cited the written Limited Installation Guarantee, the 30-Day Service Guarantee, ACE-certified technician requirements, and the Advantage Program lease model ^[53].

Best suited for. Homeowners in a Service Experts-served market who want a larger multi-location provider rather than a single local contractor; buyers who value a written one-year installation-performance guarantee and centralized-looking brand processes; and homeowners wanting bundled maintenance, priority service, and repair coverage through the Advantage Program or Maintenance+ ^[52].

Main strengths for the use case. The Limited Installation Guarantee covers new equipment installed by an authorized Service Experts technician for one year; if the equipment fails to meet manufacturer specifications, subject to customer compliance and exclusions, Service Experts promises up to three repair attempts and then replacement with a new equivalent model if the problem is not corrected ^[57]. A 30-Day Service Guarantee provides one re-service at no cost if repairs do not resolve the issue within 30 days ^[73]. The company advertises service in 31 states and more than 75 locations ^[52]. Technicians are described as ACE-certified and NATE-certified ^[111]. Maintenance+ includes preventive maintenance, priority service and installation, a 15% discount on repairs and services, and no future after-hours service fee as described by the company ^[66]. The Advantage Program bundles new equipment, installation, maintenance, repairs, parts, filters, and priority service into a recurring payment, subject to approved credit and the signed agreement ^[65].

Main limitations. The installation guarantee applies only to the new equipment installed by Service Experts, not existing equipment or the entire HVAC system, and requires notification within 30 business days of discovering the failure ^[57]. It excludes misuse, alterations, third-party work, external causes, several maintenance-related items, leaks, refrigerant-related items, and code changes ^[57]. The governing terms allow authorized third-party subcontractors, and the legal contracting entity may be Service Experts LLC, Service Experts Skilled Trades LLC, or a subsidiary ^[57]. The Advantage Program is a lease rather than a simple purchase, creating an ongoing contractual payment obligation, and early termination during a promotional period can trigger charges for elapsed months ^[64]. Independent review evidence is strongly negative: Trustpilot summary states most reviewers were unhappy, PissedConsumer shows an average rating of 1.8/5, and BBB complaints reference warranty denials, equipment mismatches, and failure to return calls ^[125]. Customer reports document installations failing two to eight months after completion, including a $9,500 install that stopped working after two months and a $12,247 system replacement with ongoing failures ^[125]. The franchise program launched in May 2025 and had only two signed franchise locations (Tulsa, Oklahoma and Memphis, Tennessee) as of February 2026, limiting validation of consistency across franchised locations ^[129].

Pricing or cost summary. Public pricing is not sufficiently standardized for a reliable national comparison. The Advantage Program page advertises a new HVAC system as low as $155 per month with zero upfront cost, but the company directs customers to the local center for participation and pricing and states that the signed lease controls ^[65]. A limited-time promotion states Service Experts will make the first six monthly payments on qualifying new lease agreements through a stated date, and early termination during the promotional period can trigger charges for elapsed months ^[70]. Maintenance+ pricing is not disclosed in public sources ^[111]. Kimi reports a franchisee fee load of roughly 8.0% of revenue plus technology fees including $500 per month base plus per-employee ServiceTitan fees, which may pressure local pricing or service quality consistency ^[85]. Pricing confidence across platforms is low.

Where platforms disagreed. Fit ratings ranged from "good" (ChatGPT, Gemini, Grok, Perplexity) to "mixed" (Claude, DeepSeek, Kimi) ^[52]. The operating structure is disputed: DeepSeek states public descriptions indicate Service Experts locations are company-operated rather than independently franchised, which is material because the buyer's need is specifically a national franchise brand, while Claude, Grok, Gemini, and Kimi describe a franchise program launched in 2025 ^[81]. Location counts conflict across sources: "over 100 service locations" versus "75+ locations" versus "80 locations" ^[111]. Anthropic also notes a possible parent-company relationship with Enercare Home & Commercial Services that is not mentioned in official Service Experts franchise or corporate materials ^[111].

What this study reveals

Questions explored

• What do AI platforms consistently say about national HVAC franchise warranty backing for residential installs?
• Why do so few national HVAC franchise brands qualify for a cross-platform consensus ranking?

Three findings dominate the cross-platform evidence. First, brand-level warranty language is abundant, but entity-level warranty liability is consistently local. All three qualifying brands publish national guarantee names - One Hour's two-year materials, labor, and craftsmanship guarantee and UWIN program, Aire Serv's Neighborly Done Right Promise, and Service Experts' Limited Installation Guarantee - yet in every case the warrantor is the local franchise, local center, or a named contracting entity rather than the parent brand ^[46]. Second, the labor-versus-parts split is the recurring structural gap. Independent evidence cited by Kimi states that HVAC labor warranties typically run one to two years while manufacturer parts warranties require strict registration within 60-90 days to reach 10-year coverage, and that diagnostic fees and refrigerant are commonly excluded from labor warranties ^[88]. Third, qualification is narrow: 28 unique entities were named across platforms, but only 3 were named by at least two platforms, which means the consensus field for this specific use case is small and concentrated.

The market also shows a maturity gradient. One Hour has the longest franchise operating history among the three and the broadest platform recognition. Aire Serv sits inside the larger Neighborly multi-brand network but was the only major Neighborly home services brand with declining unit count over three years according to Kimi ^[126]. Service Experts has the longest corporate operating history but the youngest franchise program, launched in May 2025 with two signed locations by February 2026 ^[129].

Where the AI Platforms Agreed

Questions explored

• Which national HVAC franchise brand do AI platforms agree is the top choice for warranty backed installs?
• Do AI platforms agree that national HVAC franchise warranties are uniform across locations?

Platforms agreed on several points. One Hour was named by all seven platforms and ranked first by five, making it the only entity with unanimous recognition ^[128]. All platforms that assessed One Hour cited the two-year guarantee and UWIN as the primary warranty-backing assets ^[42]. All platforms that assessed Aire Serv cited the Neighborly Done Right Promise as the core written backing, and all agreed it is a workmanship re-performance promise rather than an equipment or parts warranty ^[38]. All platforms that assessed Service Experts cited the one-year installation guarantee and the 30-day service guarantee ^[53]. Platforms also agreed across all three entities that locations are independently owned or location-specific, that pricing is not standardized nationally, and that buyers must verify local written terms before signing ^[41].

Where the AI Platforms Disagreed

Questions explored

• Why do AI platforms disagree about whether One Hour offers a 10-year parts-and-labor warranty?
• Is Service Experts a franchise network or a company-owned network, and why does that matter for warranty backing?

The most consequential disagreement concerns One Hour's extended warranty. Deepseek and Perplexity reference a published 10-year parts-and-labor option available in some markets, with Perplexity noting it appears tied to Comfort Club membership and is location- and plan-dependent ^[10]. OpenAI, Claude, and Kimi state that no standardized 10-year parts-and-labor offer was verified across the network, and Kimi explicitly notes that whether the "10-year parts-and-labor option" is a One Hour-specific program or a combined manufacturer and extended warranty purchase is unclear ^[46]. Fit ratings for One Hour ranged from "strong" to "mixed" across platforms ^[7].

A second disagreement concerns Service Experts' operating structure. Deepseek states that public descriptions indicate company-operated locations rather than independently franchised ones, which weakens the "national franchise" fit for this specific buyer need ^[81]. Anthropic, Grok, Gemini, and Kimi describe a franchise program launched in 2025 with standardized operating systems and training infrastructure ^[127]. The exact number of active franchise versus company-owned locations post-2025 launch is unclear from public sources ^[58].

A third disagreement concerns the Aire Serv Done Right Promise term. Most current sources state 60 days, while older company materials and some location pages state one year, and Perplexity explicitly flags the conflict ^[38]. Location counts for Aire Serv also conflict across sources ^[16].

How to compare your options

Questions explored

• What should a buyer check before choosing a national HVAC franchise brand for warranty backed installs?
• Which national HVAC franchise brand has the lowest published cost for a warranty backed install, and what fees apply?

Start with the warranty obligor, not the brand name. Ask which legal entity will sign the installation contract and be financially responsible for the labor warranty if the local franchise closes, changes ownership, or stops servicing the territory ^[46]. Then separate the three warranty layers: the brand's own workmanship or satisfaction promise, the manufacturer parts warranty, and any extended labor coverage. One Hour's two-year guarantee is a labor and workmanship warranty, not a manufacturer parts warranty, and registration failures can reduce manufacturer coverage from 10 years to 5 years ^[79]. Aire Serv warrants only its own services and disclaims warranties on third-party manufactured goods ^[2]. Service Experts' guarantee covers only the new equipment it installs, not the entire system ^[57].

On cost, none of the three publishes a national installation price. One Hour uses StraightForward Pricing with diagnostic fees typically $79 to $100+ depending on branch ^[92]. Aire Serv advertises job-based upfront pricing with promotional discounts such as $500 off installation at participating locations ^[37]. Service Experts advertises the Advantage Program lease from as low as $155 per month with zero down, but that is a lease rather than a purchase and carries early-termination exposure ^[54]. Buyers comparing total cost should request itemized written proposals covering equipment, labor, permits, electrical work, ductwork, disposal, refrigerant, and any membership or maintenance requirement, because all three brands condition coverage on maintenance compliance or technician recommendations ^[46].

Methodology

This index used one standardized prompt sent once to each of 7 included AI platforms: ChatGPT, Claude, DeepSeek, Grok, Perplexity, Kimi, and Gemini. The prompt asked which national HVAC franchise or chain brands deliver reliably on consistent service standards and clearly backed warranties for a homeowner who prefers a recognized national brand over a local independent. Platform responses were collected, entities were extracted, and the final ranking table was calculated from platform mentions, then average listed rank, then best listed rank. An entity qualified for the consensus ranking only if it was named by at least two platforms during ranking discovery. Platform mentions count only ranking-discovery mentions and do not reflect the number of platforms that later completed a fit assessment. The final ranking table is the sole authority for rank, platform mentions, platform share, average listed position, and best position. Entity evidence bundles are the authority for buyer fit, features, pricing, strengths, limitations, disagreements, and citations. Citations are platform-reported evidence, not independently verified facts. Company-owned sources materially outnumber independent sources for Aire Serv and Service Experts, and company claims should not be described as independently verified.

Research limitations

Several limitations apply. The study used one standardized prompt sent once to each platform; AI answers can vary by date, wording, location, account state, model, interface, browsing configuration, and the sources retrieved. Platform-reported research dates differed from the authoritative run date of 2026-10-01 for DeepSeek (2026-01-22 for One Hour, 2026-01-08 for Aire Serv, 2026-01-15 for Service Experts); these are provenance metadata and do not independently prove freshness. Platform recommendations are market intelligence, not independent customer reviews or proof of quality. The supplied URLs were collected from platform responses and were not independently validated by the writer stage. Official-site retrieval failed for One Hour and Aire Serv, and Service Experts' official page retrieval returned an invalid URL error, so no failed fetch was used as a verified domain key. The deterministic identity audit flagged conflicting official domains and unresolved identity for One Hour and Service Experts. Deepseek ran without search enabled, so its claims require explicit verification before being described as current facts. Company-owned citations materially outnumber independent citations for Aire Serv and Service Experts. Citations are platform-reported evidence, not independently verified facts. Where sources conflicted on warranty terms, pricing, location counts, or operating structure, this report describes the conflict rather than resolving it.

The consensus assessment

One Hour Heating & Air Conditioning is the consensus leader for national franchise warranty backed installs, named by all 7 platforms and ranked first by 5. It offers the broadest brand recognition, a published two-year materials, labor, and craftsmanship guarantee, and the UWIN satisfaction-accountability program, but its warranty execution varies by independently owned franchise, manufacturer parts registration is not standardized, and the warranty is described as non-transferable. Aire Serv is the strongest alternative for buyers who want a written workmanship re-performance promise and Neighborly network affiliation, with the important caveat that the Done Right Promise is not a comprehensive equipment or parts warranty. Service Experts is the best fit for buyers who want a written one-year installation-performance guarantee with defined repair attempts and optional bundled maintenance or lease coverage, but its franchise program is new, its independent review record is weak, and the Advantage Program is a lease rather than a purchase. No entity in this study offers a fully uniform, identical nationwide warranty contract in every market, so buyers should verify the local contracting entity, written warranty scope, registration responsibility, and total cost before signing.

Frequently Asked Questions

Which national HVAC franchise brand is best for warranty backed installs?

One Hour Heating & Air Conditioning ranked first, named by all 7 platforms with an average listed position of 1.57. Aire Serv ranked second and Service Experts third.

Does One Hour Heating & Air Conditioning offer a 10-year parts-and-labor warranty?

Platforms disagreed. Deepseek and Perplexity reference a published 10-year parts-and-labor option in some markets, while ChatGPT, Claude, and Kimi state that no standardized 10-year parts-and-labor offer was verified across the network. Buyers should request the exact written warranty from the local franchise.

Does the Aire Serv Done Right Promise cover HVAC equipment?

No. The published promise states that Aire Serv provides a service promise and disclaims warranties for third-party manufactured materials or goods installed with the service. Equipment defects fall under the manufacturer's warranty.

Is the Service Experts Advantage Program a purchase or a lease?

It is a lease. The Advantage Program bundles new equipment, installation, maintenance, repairs, and filters into a recurring monthly payment, subject to approved credit and the signed agreement, and early termination during a promotional period can trigger charges for elapsed months.

Are these warranties transferable if I sell my home?

One Hour's reviewed local terms describe the warranty as non-transferable. Aire Serv's Advantage Plan benefits are described as transferable if the home is sold in Gemini's evidence. Service Experts' Advantage Program lease is described as fully transferable to new homeowners upon home sale in Gemini's evidence. Buyers should confirm transferability in the local written contract.

Can I supply my own thermostat or HVAC equipment?

Aire Serv maintains a strict policy of only installing and warrantying equipment it furnishes directly. One Hour and Service Experts publish no equivalent allowance in the reviewed evidence.

Why did only 3 of 28 named entities qualify?

The eligibility rule required an entity to be named by at least two platforms during ranking discovery. Most of the 28 unique entities were named by only one platform.
