This is my first time here. I have a Goodman heat pump and I noticed that the suction line from the condenser unit is putting out 43 degrees in the cooling mode. However when I checked the air-register just above the indoor unit is putting out 62 degrees. It’s a three floor house, I also noticed that the basement don’t have return are supply registers, could this contribute to the house no cooling as suppose to?
Can you test the defrost board in the summer 85 degrees? If yes how should I do it?
