a buddy of mine has a pizza shop and his cooler was fine untill he moves the compresser. he moved it from one corner to the other side of the same corner. now he keeps calling me to fix it. the cooler won't go below 50 degrees. before it was at 40 degrees. i don't know anything about coolers. and my final question is. do they make a R-44 or A R-41 refrigerant?
