# Public Claim and Source Ledger for Who Makes Major HVAC Brands

Version: 2.3.2 pre-publication  
Review date: July 11, 2026  
Canonical article: `resources/who-makes-hvac-brands.md`  
Machine-readable atomic records: `resources/who-makes-hvac-brands.data.json`

Every brand record keeps owner/controller, trademark/license, manufacturer, warrantor, marketer, and equipment evidence separate. "Not established" records are findings about the reviewed evidence, not assertions that a relationship does not exist.

## Coverage and methodology claims

| Claim ID | Public claim | Source or rule | Disposition and limit |
|---|---|---|---|
| SCOPE-001 | Version 2.3.2 covers 58 consumer brands with current or unresolved U.S. central-HVAC relevance. | Count of records in `who-makes-hvac-brands.data.json` | Verified mechanically; not a complete census of every regional U.S. label. |
| SCOPE-002 | Ductless, geothermal, manufactured-housing-only, vertical-through-the-wall, PTAC/PTHP, specialty-residential, and commercial-only systems are excluded. | Publisher scope rule | This is an editorial boundary, not a market claim. |
| SCOPE-003 | Whole-home central-ducted products from brands also known for ductless are included. | Publisher edge-case rule; Midea, GREE, Ecoer, Mitsubishi Electric, LG, Samsung, and TOSOT product sources below | Applies only when current first-party central-ducted evidence exists. |
| METHOD-001 | Owner/controller, trademark license, manufacturer, warrantor, and marketer are distinct relationship types. | Adversarial source-entailment review; public editorial taxonomy | A warrantor or certification holder is never promoted to manufacturer unless the document expressly says manufacturer. |
| METHOD-002 | Evidence categories are publisher-created, not industry-standard labels. | Public methodology | Categories must not be attributed to AHRI, UL, or a manufacturer. |
| METHOD-003 | First-party technical records control model statements but are not independent corroboration. | Public source hierarchy | Marketing pages receive less weight than dated technical records. |
| METHOD-004 | Positive dataset edges use only directly entailing `source_ids`; not-established edges use `object:null` and list the bounded search set in `reviewed_source_ids`. | Dataset schema version 2.3.2 | A reviewed source set supports the negative-search boundary, not a positive entity relationship. |
| METHOD-005 | Historical and component claims carry an evidence class, date scope, equipment scope, direct sources, and a separate limit. | Dataset schema version 2.3.2 | Supplier capability, catalog availability, service interchange, and factory/model evidence are not interchangeable. |
