To make a short story long, R410A and R22 are refrigerants. They are both good refrigerants and they both work, but they have to be charged in the system at different pressures. R410A is a higher pressure system and R22 is a lower pressure system.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.

I like to see an average range of 58-85 PSI on the low side and 120-300 PSI on the high side. These indicate that the unit is running okay and should be cooling properly. TL;DR: R22 is almost phased out and even banned.The R-410A has about 40 percent less heat-carrying capacity than the R-22. This causes the reduction of the replacement between the two different compressors. If an R-22 compressor has R-410A refrigerant put into the system, the motors will overload and burn out. The overloading can also cause the motor to start tripping the breaker, shutting ...
