Which model of indoor and outdoor did you go with? My research into multi split suggest that going with multiple mini splits is more efficient. There is also a concern that multi split is not eligible for IRA tax credit
I went with the Daikin 5MXS48TVJU for the condenser and 3 models of the head units. All Daikin. I didn’t want a bunch of condensers around the house, and I didn’t want to run power everywhere. I’m not sure about efficiency compared to multiple condensers or the IRA stuff.
