Had mitsubishi units installed in the northeast USA a couple of years ago, for a 1.5k sqft house all of our quotes were ~15K.
Also, I have 15k BTU available for one or two additional head units. I opted for this approach instead of under-sizing the heat pump or assuming we'd need the extra head unit and buying them during initial install. Half of our basement has no ducting so we thought a unit for heat would be nice. Also considered adding another unit in second floor landing for additional capacity. Not sure yet if we will.
My only complaint is the Kumo cloud is terrible.
They’re right though, the Kumo app is truly awful. Which is sad as it’s also quite useful.
