The ceilings are angled and the high point is in the middle of the house so connecting an outdoor unit to a high wall indoor unit at the highest point is not easy. We want cooling so a floor unit is out.
For the bedroom, which is in the middle of the house, high wall indoor would mean interior visible piping to a roof mounted outdoor unit attached to a wood wall. The roof is a split design. Apart from the asthetics, I'm concerned about tradespeople walking on my decramastic tile roof and vibrations from the outdoor unit.
The installers didn't seem too fussed where things went so I'm wondering how important optimal placement is now?
