Wall-mounted air conditioning — mini-splits and PTAC units

Model the AC you'll actually install: high-wall mini-split heads, low floor consoles, or through-wall PTAC units.

Ductless systems are everywhere now, and they claim wall space you should plan around. RoomSketch3D has three wall AC types, each mounting at its real height: the Mini-Split (Wall) head up high, the Mini-Split (Floor Console) down low, and the through-wall PTAC Unit near the floor — hotel-room style.

Step by step

  1. 1

    Find the unit in the catalog

    Search the catalog for mini-split or PTAC, pick the type, then tap the wall where it mounts.

    The unit sits on the wall like any fixture — drag it along the wall to reposition.
  2. 2

    Pick the spot with airflow in mind

    Mini-split heads want a clear throw across the room — avoid blowing straight onto the bed or sofa. PTACs need clear floor space in front, usually under a window.

  3. 3

    Check heights in 3D and elevations

    Each type renders at its true mounting height — heads high on the wall, consoles and PTACs low — so 3D views and elevations show the room as it will really look.

    The head mounts high on the wall, exactly where the installer would put it.

Tips

Mind the outdoor unit

Mini-splits need an outdoor condenser — if you've built a yard, drop the outdoor unit from the catalog beside the wall the line-set exits.
