I had an air conditioner/furnace installed years ago and just found out it was not performed to code or to manufacturers specifications regarding the flue pipe through the roof. I had an issue with Amos covering a faulty AC condenser years ago also until Home Depot made them take care of it under warranty. I’m not going to even hassle with asking them to come back out because I have another contractor. I wish you would have done it right the first time!
