I've done a few installs but this is the first on my own. Had a friend with me that had no hvac experience but a little auto body work under his belt. We added all new supply metal work and added some return. I have very little sheet metal experience other than putting in the pre made plenum someone made at the shop and adding supplies and some other little stuff. All the sheet metal we picked up from menards ( was a bit cheaper than HD ) and made the plenum on site out of sheets and s-lock using just a folding bar and a screwdriver with a straight edge for a brake. Some areas look better than others and all the pics are pre-tape but I definitely learned a lot and have a new appreciation for metal work. It's something that's intimidated me since I started in the trade and I finally feel like I had a light bulb moment if that makes sense. I know we cut s-lock to short in spots and there's some other ugly areas but overall, how does it look?? I know I'll get shit for the single pipe system but it's a really drafty Michigan basement with enough space for combustion per manual. Looking forward to the next one and learning how to do this better.
