Installed a new 96.5% efficiency furnace today.

Picked up a new stock but dented Daikin furnace for $1200 a while back, and finally got around to installing it today. I had measured up and commissioned a plenum but fucked up a little bit, so it took longer to get the S-cleats properly installed and the plenum airtight than removing the old one, cutting in the cold air return, wiring the electrical and running the intake/exhaust pipes took put together. Approved ducting methods seem so fucking archaic, everything has to be tight but you can't just put things together without taking half a dozen things apart to get it to fit. Of course, I had to fix one transition because I lost my temper and punched the shit out of it.

On the plus side, it only took 2 trips to Home Despot, the second one because the old switch had been drywalled in and was completely inaccessible. I cut the wires off it and put a new box and switch where I could reach it.

I need to get a condensate pump yet, and call for an inspection, but winter is still a few months off so I have time.
