With 95 F outdoor temperature and 80 F indoor temperature you can expect a 125 F condensing temperature, (ambient plus 30). Indoor temperature (80 F) minus 40 F = 40 F evaporating temperature. Convert temperature to pressure, R 22 at 40 F = 70 psi.
What is the normal suction and discharge pressure for R22?
For example, a high-efficiency condensing unit using R-22 typically operates with a suction pressuresuction pressureIn refrigeration and air conditioning systems, the suction pressure' (also called the low-side pressure) is the intake pressure generated by the system compressor while operating. As the cell absorbs more and more water its Turgor Pressure increases and Osmotic Pressure decreases.https://en.wikipedia.org › wiki › Suction_pressureSuction pressure - Wikipedia of about 68 psi and a discharge pressure of about 250 psi at an outdoor temperature of 95°F.

What should R22 pressures be on a 70 degree day?
roughly 201 PSIG
What should the high and low side pressures be R22?
The short answer to your question is that the high and low side pressure for R22 refrigerant is 250 and 68 psi at 35 degrees C, respectively as shown below.
What is normal operating pressure for R22?
R22 gauge pressure is 10.9 bar or 158.2 psi. High side pressure typically varies by equipment and metering controls.
