I had an HVAC person come out and check my unit because water is sitting in my ducts and has now run through the walls from the attic to the main level in the kitchen. He says that my evaporator coils was leaking freon and it caused the problem. My question is how can leaking freon cause 3 ducts to fill up with sitting water? He was suppose to write a detailed description on the invoice but it wasnt detailed enough. Now I cant get in touch with him. Someone please help me understand how that much water can be generated from leaking coils!
