Best locations for minisplits on outside of building
I’m zeroing in on my HVAC requirements for my Pretty Good House renovation and have a question regarding the location of the exterior units.
I will have two single head units for approx 2200 sqft of conditioned space. 1500+ on the main floor and an additional ~700 in the basement. The two spaces are connected thru an open 8×8 stairwell.
My options for the outside units are:
1) Mount both on the garage side of the house. This is the most weather sheltered side of the house, but will result in refrigerant line runs of ~35 ft for one unit and ~60 ft for the second unit.
2) Mount one unit on the garage side and the second unit on the other end of the house. This will result in refrigerant line runs of ~35 ft and ~20 ft.
3) Mount one unit at the rear of the house adjacent to a hardscaped patio and the second on the far end of the house. Both sets of refrigerant lines will be ~20 ft.
Which location makes the most sense and why?
