I bought a Sanyo dual zone mini split air conditioners, my installer recommends putting it on the side of my house, attaching it to the house itself. I was told that it should be mounted on a cement base at ground level. My installer tells me that it require 44 inch sono tubes because of the frost line here in CT. Do I let him put it on the side of the house, the compressor weighs 139lbs, it's a Sanyo CM2472. Thanks Gregory

I'm going to enclose the porch at my lake home (Lake of the Ozarks, in Central Misourri). It faces the lake (Southwest), and is 32' long by 7' wide, with an 8' ceiling. I'll have 2 X 6 walls, with 8 - 42" X 60" windows (vinyl sliders - low E & Argon, probably builders grade Jeld Wen or similar) along the lake side. Both ends will have sliding patio doors, so it will be almost all windows on three sides. It's quite sunny, so there will be direct sunlight on the windows. I'll insulate the ceiling and sidewalls with fiberglass batt insulation. The roof of this porch is the upstairs deck, which is waterproof. I'll finish the ceiling, probably with aluminum soffit material. I'm planning on heating & A/C with a through-wall heat pump (with an built in electric heating element for when it's too cold for the heat pump). I'll install the unit below a window in the center of the long wall, and I'll have a couple of ceiling fans in the room to help circulate air. Temps in the summer frequently exceed 90 degrees, and will often hit 100. Winter temps are typically between 30 and 50, although it will occaisionally get colder. Although we won't necessarily run the heat / air all the time, we'll want to be able to use it when we choose to, even in the extremes. I'm pretty sure it will harder to cool this room than keep it warm, due to the sun exposure. Any ideas what I need for capacity?
