Though it can vary, the low side pressure of a mini split should not fall below 100 psi or raise beyond 160 psi. The working pressure of mini splits is depending on factors such as the weather and cooling load.Mini split manufacturers have been saying that since befrore R410A came out. All the old R22 units told you to weigh in charge only. And nobody is going to do that. It's like an quick change oil place telling customers that their engines have to be pulled and weighed to check their oil levels. No, its not the same.The perfect refrigerant reading depends on several factors, like atmospheric pressure and temperature. 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.New Refrigerant Regulations. A new, more environmentally friendly refrigerant, R-454b, will replace R-410A. In addition, the new refrigerant can make air conditioners more efficient, which will save homeowners money. The current refrigerant, R-410A, is a hydrofluorocarbon.
