I arrived for a install warranty water leak. I inspected the system and found that the drain line for the air conditioner was glued and installed properly. The drain line for the 90% furnace was installed but not glued. When they switched from ac to heat the furnace started making water and drained into the living room ceiling and collapsed the sheet rock in the living room. We have contracted a sheet rock company to come out of Friday the 25th to remove all dammed sheet rock textured and paint.
