I just wanted to get some opinions on the drop in refrigerant for R22, refrigerant M099. Will M099 work the same as R22? I have 105 ton to 115 ton Trane Intellipak units and want to make sure there isn't a whole lot of retrofitting for this drop in refrigerant. I would like to hear some of your opinions on those who have used M099 and get more information. Thanks!!!
