R22 low side pressure at 70 degrees.
Mar 21, 2016 · Although it's really impossible to say what the "normal operating pressures" are for an R410A system as it's based on so many variables:load, humidity, condition of outdoor coil (clean or dirty), I would expect to see 120-135 on the low side and about 280-300 on the high side. Again, these are just examples.

Most technicians in the HVAC field know the normal range of operation for the low-pressure side of an air conditioning system. This tends to be around 60 PSI to 85 PSI for R-22 and 105 PSI to 143 PSI for R-410A and is dependent upon operating conditions. On the high-pressure side of the system, there is a wide variation in pressure due to the wide outdoor temperature swing and due to the ...
Backed when I worked up in the northeast hp cut out on r22 was 400 to 425 psig on air cooled equipment and 275 to 300 psig on water cooled units. That was the norm. 450 psig is a little high but I guess maybe in hotter climates that makes sense. Clean condensers are a must in hot weather especially when outdoor temps get above design temp.Low-Pressure Suction Side. The low-pressure side, when connected to the gauge, should read less than 100 psi. PSI is the common measurement for pressure used in terms of pounds per square inch. By the time the refrigerant reaches these lines it has lost most of its heat and has collapsed into a liquid state, taking up less volume.
