Intry Verified receipt

Is the Intry Cold-Climate Heat Pump Capacity Calculator accurate?

The provenance receipt for the Intry Cold-Climate Heat Pump Capacity Calculator: 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: It computes from the sources listed in the source receipt on its tool page, and our automated checks hold its answers against values written from those sources for the cases the checks cover, not for every input you can enter. The manufacturer's engineering data or a Manual-J load calculation by an HVAC pro has final say. Every figure an Intry calculator computes comes from a locked source module, not hand-typed. 30959 automated checks, one suite for the whole site rather than a per-tool count, re-derive the numbers before each deploy from the tables this site transcribed from the AHRI-certified NEEP ccASHP data it came from. 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
AHRI-certified NEEP ccASHP database · Manufacturer submittal · Linear interpolation of the MAX-capacity curve (derived). Reused verbatim from the locked engine, never re-written for this page. The documents it rests on are listed in the source receipt on the tool page.
Edition
not a code table
Checked
Before any release, an automated check runs the locked engine that produces these figures and holds its answers against values written from the source it cites, so a checked number answers to its source and not merely to itself. The check covers the cases someone wrote a check for, not every input the tool accepts: it tells you where a number comes from, and it is not a proof of every value. As of the current build that suite holds 30959 checks, and this page has to clear them too. This is our own deterministic gate, not a third-party audit.
Runnable
Exposed at the Intry MCP endpoint. An AI assistant can run this calculator, and before each release an automated check confirms the answer it returns is identical to the one the website's own engine produces.
Final say
The manufacturer's engineering data or a Manual-J load calculation by an HVAC pro has final say.
