Desperate help, minisplit sizing
I’m a GC building my own home. I live in an extremely rural area with very few knowledgeable hvac professionals within 300 miles. I have decided to go with mitsubishi ductless mini splits to heat and cool the entire house. Basically I need help choosing what size units to purchase, how many heads, and to me most importantly where to place the units. This home will be occupied by just me and the wife so interior doors will be open most of the time. Walls will be a double 2×4 wall system spaced 1″ and filled with wet cellulose, along with a 1/2″ layer of polyiso on the exterior of the walls bringing the r value to around R31-R32. The ceilings are 9ft tall and will be an R60. Any help is greatly appreciated. Below is a rough layout of the home.
