Overall we are satisfied with our new high-efficiency furnace. Chris was very knowledgeable, answered all of our questions, and didn't push us to make a decision on the spot, like some other companies do. Also, the price can't be beat!
We couldn't give a perfect rating however, because we did experience a couple issues during the installation. Dieter was our installer and he was polite, friendly, and arrived promptly on time. The furnace appears to have been installed properly, and is working great so far.
Unfortunately though, he did not install the furnace exhaust pipe according to code. We were surprised to see that the hole was drilled too close to our hot water heater air intake (less than 3 feet away) and we had to tell him ourselves that this was not appropriate. He put an extension on the pipe to direct it further away, but it looks strange now and is blowing exhaust out right next to our back door (see attached before and after photos).
The other issue was that after he left, we noticed a bunch of screws, debris, and random bits of metal left around the work area. This isn't a huge issue, but from what various companies told us, we expected that the installers would always clean up their messes after they are finished.
We would still recommend Convertible to those who are looking to buy a new furnace, but we would also recommend verifying all of the details on the day of the install to avoid any unfortunate surprises.
