Garage HVAC

Heating. Jeanne really likes the  Cadet Softheat units we have in the basement. So a single small unit in the storage area would work and a single longer unit in the studio under the window should do it. A wall heater in the bath. All heaters should be 220 of course. Cooling.  The cooling feature of a heat pump would not be necessary and a sized AC in the studio would work.

I was just thinking for the garage roof/studio floor: ~5 inches of spray foam, which provides R30 – R32 insulation and completely seals the floor from air leaks.

 David. If the budget allowed, I'd say go with a ductless split system heat pump, but that's probably a $4K purchase, and likely out of range. Only reason is noise. Window/wall A/C units are all loud as fuck, but they do work reasonably well.
