Air conditioning project.
Supposedly, the hardest part of the project is behind us. I ran the ridiculously-expensive 7/8" copper freon lines ($259 plus tax) and a3/8" partner (~$60), which I coated in the best insulation that I could buy (~$120 worth), through the attic last night. They barely reach the utility closet without an inch to spare, which is good, because they only sell the copper A/C lines in 50 foot lengths at my local A/C supply house. This was particularly arduous because the attic was very warm, and I had about 24" of blown-in insulation covering the joists that I was trying to walk on so as not to fall through the ceiling, while directing a very delicate pipe through the attic around ducts and trusses and such. Whot phun.
Today, I need to build out the ducting from the coils to the plenum, reconnect the stovepipe to the heater (need more stove pipe. Why do the sections keep coming apart? It's not supposed to be this hard.), connect the copper to the outside compressor and the inside evaporator, and connect the electrical, and see if it turns on. We shall see.
Total price tag thus far for a new 5 tonne gas furnace and 5 tonne a/c unit is about $1900, but I reckon with the cost of incidentals like fuel to and from the store, some tools, and such, I'll be well over $2k.
By the way, the Shark Bite water connection devices, which simply push onto the pipe to connect copper to copper, or even copper to PVC, are pretty nifty. They made the re-installation of the hot water heater take less time than it took to even cut one of the copper pipes that originally connected it to the house water system.
My partner's dad needs a special thank-you when this is done. The guy is working like a dog for me, for free, because he apparently just wants to. I can't express my gratitude to the guy enough.
