The inside unit fan was getting louder because it developed mold on the fan blades over the winter. I was told the drain pipe may have back drafted from a strong wind as a possible cause. The service tech said he never saw anything like it when he cleaned it. The fan seems to be getting louder. This unit is 3 years old. Any suggestions to return to the "whisper" quiet we once enjoyed?
