About R-410A
R-410A (Puron) is the high-pressure HFC used in most US residential AC and heat pump systems built from 2010 to 2024.
The chart shows saturation temperature in °F at gauge pressure (PSIG), sea level, every 10 PSI from 0 to 600 PSIG. Readings between rows are linearly interpolated, the same way FieldLoom does it on the job.
Use it with the superheat and subcooling calculators, or see all refrigerants.
Questions
What pressure is 40°F for R-410A?
About 119 PSIG.
What pressure is 100°F for R-410A?
About 317 PSIG.
Are these pressures gauge or absolute?
Gauge pressure (PSIG) at sea level, the same as your manifold reads.
