My downstairs unit stopped running Friday so I called my A/C company out. It was 2 lbs. low on freon which says leak. He tells me he could do the leak test for $101.00 or save me the money and tell me that its probably in the evaporator coils. Apparently leakage in the coils is common in Amana units. Then he tells me I would have to have my system replaced because the type freon in the house uses R22 and EPA says you have to use the new "Puron." My question is why cant the leak in the coils be repaired? My home is less than 7 years old. I will call them back later to answer this and possibly schedule a free estimate to replace my equipment but I know some of you are in the biz and wanted your opinion. I understand nuclear fusion, frying turkeys and even the infield fly rule but HVAC slays me. :sadwave:
