Intry Verified receipt
Is the Intry Tonnage From Model Number accurate?
The provenance receipt for the Intry Tonnage From Model Number: the exact authority its values derive from, the edition they are keyed to, who has final say, and what our automated checks hold them against, rebuilt from their cited source.
Short answer: Every figure an Intry calculator computes comes from a locked source module, not hand-typed. 27820 automated checks re-derive and source-check the numbers against the manufacturer model-number nomenclature it was decoded from before each deploy. This is our own deterministic gate, not a third-party audit. The per-tool receipt is public at https://www.intrysys.com/verified.
The receipt
- Calculated from
- The BTU/1000 capacity ladder (024 = 2 tons) · Per-brand model nomenclature (fixed capacity position) · Mini split direct BTU class, and the LG single-zone legend that is not one · The independent capacity backtest (AHRI Certification Directory) · Furnace MBH exclusion, the estimate fallback, and when the tool refuses. Reused verbatim from the locked engine, never re-written for this page.
- Checked
- Before any release, an automated check rebuilds the calculated figures from the locked engine that produces them and holds each one against the source it cites, so a number answers to its source and not merely to itself. As of the current build that suite holds 27820 checks, and this page has to clear them too. This is our own deterministic gate, not a third-party audit.
- Runnable
- A reference engine behind the published numbers on this site. Runnable access is offered on the calculators exposed at the Intry MCP endpoint.
- Final say
- The unit's rating plate and its BTU/h rating have final say; brand nomenclature varies and changes across product generations.
