MaryB's post on her new shop inspired me to throw up this post on mine. I had the shell built about 12 years ago and due to a divorce and life in general, I never got around to finishing it off. But recently, I find myself nearing retirement and wanted to have my man cave finished when I get there. Basic structure 30' by 40' by 14' Shed for the compressor And the deal of the decade. My electrician also installs air conditioning. He had a new unit setting in the back of his shop that he wasn't able to sell in 4 years because it wasn't a heat pump style heating unit, only resistance heat. He was getting ready to ship it back to the manufacturer for a loss, but offered me the unit for his cost, thus saving him shipping costs. It's a 3 ton unit with a full 10 year warranty! I'm not too worried about operating costs in that I'll be keeping the shop around 58F in the winter and around 80F in the summer. (We have a relatively warm climate here.) I'll also will have R18 walls and R30 insulation in the ceilings when I'm done. More to come.
