As part of a basement reno, I needed to have the supply and return ducts changed out and also moved closer to the floor joist to allow for maximum head clearance. Big Valley did a great job of this. In addition I had bathroom exhaust fan ducting installed as well as the range hood ducting. They did these and everything was fine, what I didn't like was the 30° elbows on both runs just before they hit the exterior wall when they could have gone straight out the wall if they had piloted out the hole before drilling the big 6" hole. Minor, but I've always been told to only add elbows when 100% needed and in this case I didn't see the need other than the 6" was drilled first, then the ducting added after. I talked to the sales guy and was asked to send pictures but never heard back. That said, everything is working fine and neither the bathroom fan or the range hood seem to be making more noise than they should. Again, just a little detail that I find separates "the best" from "the rest". I think if they had followed up with me after I sent the pictures, explaining why they had to put these elbows in, it would have showed me they appreciated my business, but since they didn't, I felt like they had their money they were done with me. This is too bad as I'm now looking for a furnace and AC unit but will now shop around to see if there are better options in Maple Ridge before contacting them for a quote.
