Does anyone have any feedback that has used an alternate to R22 refrigerant such as 422B? I know that the system has to be completely flat, and void of any R22 to charge this into the system, but was curious to hear from anyone that has used this in place of R22, and what they think of it as a replacement, positive or negative. Thanks to all
