Cost and sizing for a Mitsubishi City Multi ductless
I wanted a second opinion on the quote and sizing of a Mitsubishi City multi ductless system. The house is 1570 sq ft, in a hot humid climate. I ran a manual J using CoolCalc and came up with 30k BTU load for the house. I got quoted a 3 ton city multi system for a bit over $10k.
For reference we have R24 open cell in the attic, R13 mineral wool block walls, tilt and turn windows, and 50 cfm of mechanical ventilation.
Does this seem like reasonable sizing, and do you think the price is fair? This is our first build so having second opinions from this community is important as most locals have no idea about these systems and dont even install insulation most of the time.
