⚪pt_lookup(refrigerant, temp_f)
Saturation pressure (bubble and dew, in psig) for a refrigerant at a temperature in Fahrenheit. For certified HVAC technicians (EPA 608; A2L certification where required). Example: pt_lookup("R-454B", 45). Bubble point: use for subcooling calculations. Dew point: use for superheat calculations. Pure fluids (R-32, R-410A, R-22, R-134a) have no glide, so both values match.

}⚪pt_reverse(refrigerant, pressure_psig)
Saturation temperature (bubble and dew, in Fahrenheit) for a refrigerant at a pressure in psig. For certified HVAC technicians (EPA 608; A2L certification where required). Example: a 130 psig suction reading on R-454B -- pt_reverse("R-454B", 130). Use the DEW temperature for superheat work and the BUBBLE temperature for subcooling work on blended refrigerants.

}⚪superheat(refrigerant, suction_psig, suction_line_f)
Superheat in Fahrenheit from suction pressure (psig) and suction-line temperature (F). For certified HVAC technicians (EPA 608; A2L certification where required). Uses the DEW point as the saturation basis, which is the correct basis for blended refrigerants. Typical TXV target: 8-12F.

}⚪subcooling(refrigerant, head_psig, liquid_line_f)
Subcooling in Fahrenheit from head pressure (psig) and liquid-line temperature (F). For certified HVAC technicians (EPA 608; A2L certification where required). Uses the BUBBLE point as the saturation basis, which is the correct basis for blended refrigerants. Typical TXV target: 8-12F.

}⚪convert_units(value, from_unit, to_unit)
Convert between pressure units (psig, psia, kpa, bar) and temperature units (F, C). A bare 'psi' is treated as psig. For certified HVAC technicians (EPA 608; A2L certification where required).

}⚪refrigerant_info(refrigerant)
Reference card for a refrigerant: GWP, ASHRAE safety class, composition, typical oil, temperature glide, and handling notes. For certified HVAC technicians (EPA 608; A2L certification where required). Informational only.

}🟢diagnose(refrigerant, suction_psig, suction_line_f, head_psig, liquid_line_f, ...)
Conversational diagnostic copilot: give it field readings and get back computed superheat/subcooling plus a ranked 'check this first' list. For certified HVAC technicians (EPA 608; A2L certification where required). Informational only -- it suggests what to CHECK, never how to defeat a safety device, vent refrigerant, or work uncertified. metering: 'txv' (default) or 'fixed' for fixed-orifice/piston systems.
