Had my furnace installed by these guys. We got a 80% efficiency furnace as the 90% one was quite a bit more. They ended up having to redo some of the ductwork and venting which required them to cut holes into the drywall in areas like the garage ceiling which I wasn't very happy about. They did put a plastic cover to cover the hole but now it's a bit of an eyesore. Otherwise, the furnace is good and very quiet.
