A reference and calculator site for HVAC/R technicians, with refrigerant pressure-temperature charts and field calculations.

Landing page captured for the 2026-10-23 issue.

For: HVAC/R technicians and field service staff
Worth noticing: Blend entries distinguish liquid (bubble) and vapor (dew) values instead of collapsing them into one saturation figure.

Field notes

The gauge lookup accepts either pressure or temperature and includes elevation as an optional input. Blend data is split into liquid (bubble) and vapor (dew) readings, and the target-superheat calculator names CEC Table RA3.2-2 as its reference. The homepage attributes its refrigerant data to CoolProp 8.0 equations of state; that source claim is presented on the site, not independently verified here.
