Brand evidence
Mini-split brand supportability index
This is deliberately not a breakdown-rate ranking. We do not have failure-rate, claims, or complaint-rate data. The index measures what the catalog can actually prove: published diagnostic tables, warranty commitment, whether the tracked line is current, and how complete and conflict-free the source-backed model records are.
Read it as a supportability and manufacturer-commitment index: how much help exists when something goes wrong, and how much of the current equipment story the manufacturer backs in public.
Reliability, named honestly
A brand can be well built and still publish little diagnostic documentation. Another can publish a deep code table and still have field failures we cannot see. The page keeps those apart: published support evidence is measured; actual breakdown frequency is not.
Brand positions
Scores are rounded to the nearest five points so small differences do not look more precise than the data supports. If a dimension is not sourced in the catalog, it is left unscored and the remaining dimensions are reweighted. Brands with fewer than three sourced dimensions are not ranked.
Panasonic lands in the strong supportability evidence band at 100/100. Strongest measured area: diagnostic documentation; weakest measured area: catalog documentation quality.

Platform evidence
Shared tables are useful, but narrow evidence
Identical or near-identical fault-code tables are strong evidence of a shared control platform. They do not prove corporate ownership, and they are not a failure-rate signal. Short tables are especially easy to overread, so those are separated below.
Strong code-table signals
51 fault codes from the smaller Klimaire/Pioneer table also appear in the larger table.
Shared 51 / smaller table 51; larger table 52.
ACiQ and Midea publish the same 36-code fault table.
Shared 36 / smaller table 36; larger table 36.
Cosmo and TOSOT publish the same 14-code fault table.
Shared 14 / smaller table 14; larger table 14.
AHRI certificate check
No cross-brand shared AHRI certificate numbers are present in the current catalog.

Method and limits
The index uses only local catalog data. No complaint forums, warranty-claim databases, installer anecdotes, or new research are added here. A blank cell means the source-backed catalog does not support that dimension yet.
25% weight
Diagnostic documentation
Fault-code table depth from our local error-code catalog. Brands with no cataloged table are unscored on this dimension, not marked unreliable.

Warranty commitment
Published standard and best-case warranty terms from resolved catalog facts. Missing compressor terms are shown as a finding rather than guessed.

Catalog documentation quality
Average model completeness and publication quality, with an unresolved-fact conflict penalty when conflicts exist.
What the score does not say
- It does not estimate how often a brand breaks.
- It does not treat missing fault-code tables as proof of poor build quality.
- It does not infer warranty terms when the resolved catalog facts do not publish them.
- It does not claim shared ownership from shared code tables or shared model behavior.
