HVAC / runnable MCP tool
Run the Superheat & Subcooling Calculator in your AI assistant
Through the free Intry MCP server, Claude, ChatGPT, or Cursor runs this exact calculator and hands back a verdict and the cited source, not a guess. Tool name: superheat_subcooling.
Ask your assistant
The one rule that makes it reliable: name Intry in your question. That is what tells Claude to run the superheat_subcooling tool and answer with the real number, the verdict, and the citation. Leave Intry out and Claude may just guess from memory, which is exactly what you are trying to avoid. Type something like:
Inputs
| Field | Required | What it is |
|---|---|---|
| refrigerant | yes | Refrigerant, e.g. 'R-410A' or 'R-454B'. |
| suctionPressure | yes | Suction (low-side) gauge pressure, psig. |
| suctionTemp | yes | Suction line temperature, °F. |
| liquidPressure | yes | Liquid (high-side) gauge pressure, psig. |
| liquidTemp | yes | Liquid line temperature, °F. |
| meteringDevice | optional | txv or fixed orifice (default txv). |
| systemType | optional | Whether the system has a liquid receiver. On a receiver system the receiver holds the surplus charge, so subcooling stops indicating charge and this tool reports it as a measurement without grading it; superheat is unaffected and stays graded. Omit only if unknown: the default is derived from the refrigerant's usual application, and it refuses rather than guesses. |
Add Intry to Claude
One paste and Claude can run this tool and every other Intry calculator, right from your phone.
- Claude opens with the Intry connector already filled in. Review it and click Add.
- (If a field is blank, paste the link below into the URL field.)
- In any chat, tap + then Connectors and switch Intry on. Then name Intry in your question (“use Intry to…”) so Claude runs the tool instead of guessing.

Every answer comes with the locked modules each figure is traced to: the manufacturer PT tables behind the saturation temperatures, superheat and subcooling, and the transcribed code and service-literature constants behind the charge, metering, airflow, approach and discharge line figures, each quoted with its own source in the panel it appears in, so you can check it or show an inspector. The numbers come from the same calculator we run on intrysys.com, and we re-check every one automatically before anything goes live, so the number Claude hands you matches the code.
