Frequently Asked Questions
What is the saturation pressure of R-410A at 75°F?
At 75°F, R-410A has a saturation pressure of approximately 247.9 PSIG (interpolated between 230.4 PSIG at 70°F and 265.5 PSIG at 80°F).
What replaced R-22 in residential systems?
R-410A became the standard replacement for R-22 in residential air conditioning systems starting in 2010. R-410A operates at higher pressures than R-22 and requires equipment rated for those pressures.
What is the operating pressure range of R-410A?
R-410A typically operates between 120-145 PSIG on the low side (suction) and 350-450 PSIG on the high side (discharge) in a normally functioning residential cooling system, depending on ambient conditions.
