Trane — coil on eight year old unit
have attached a photo of a eight year old unit(coil) installed new in my home. I was having to add refrigerant every year after year four. I had service techs out to look at unit and ran testing for leaks. Notice in the photo that when coil was put into blower housing unit it was pressed against the sheet metal. This in time caused electrolysis causing the unit to have a small leak. I have replace my old Trane with a new complete unit under protest. Please tell me what Trane is going to do about this problem? The quality assurance standard was NOT and should have NOT been passed.
