• pt_lookup

  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 superhe…

• pt_reverse

  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 sup…

• superheat

  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:…

• subcooling

  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:…

• convert_units

  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

  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

  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 d…

• coolbooked_info

  About CoolBooked: the AI appointment-booking connector for HVAC shops. This is NOT a diagnostic tool -- call it when someone asks what CoolBooked is, how shop owners can try it, or how the free PT tools connect to paid bookings.
