If it's four or three bars, you don't need to charge it.We recommend you don't mix R-22 and R-410a. They do not work well together. However, if you're talking about completely replacing R-22 with R-410a, the answer is also probably not. R-410a has to be charged at a higher pressure than R-22. Your old system may not be suited to operating at that higher pressure.Today's question comes from Amos. "Hey Dan, do I need to change the TXV valve when switching the outdoor condenser from R-22 refrigerant to R410A?" Yes, you are going to have to change out the TXV. Why?
