What should the reading for R-22 be?

Answer 1

The reading for R-22, a commonly used refrigerant, typically depends on the system's operating conditions, including temperature and pressure. Generally, at a temperature of 75°F (24°C), the corresponding pressure for R-22 is around 70-75 psi on the low side and 220-250 psi on the high side. However, it's important to refer to the manufacturer's specifications and pressure-temperature charts for accurate readings specific to your system. Always ensure proper safety precautions when handling refrigerants.
