Which system to install: a conventional ducted heat pump or 7 minisplits?
I'm building a 3300 sqft house with blower door test around 1 ach, R31 walls, and a R 60 vented attic in eastern PA (Zone 5). I'm considering using the minisplits from Fujitsu.
My one quote for the conventional system came in for a 3-ton system after he put the house through his software and the other quote was for 7 Fujitsu 9RLS minisplits. It might be overkill with that number of units. I will be ventilating the house with a ultimateAir ERV.
I would like to go with the minisplits for the whole house but I don't know anyone who has used them. Can anyone give me some advice on the pros and cons for using them or does anyone have experience using them to heat and cool the entire house? By the way, both my wife and I are fine with the looks of them on the wall and with having 7 compressors outside.
