Mitsubishi Floor-Mounted Indoor Units
Low on the wall, like the radiator it replaces — and the right answer for sunrooms, cabins, and any room where the wall space is up high or nonexistent.

Heat where you feel it — at floor level
A floor-mounted unit sits a few inches off the floor against the wall, exactly where a baseboard or radiator would be. In heating mode it pushes warm air along the floor from two outlets — top and bottom — so the room warms from your feet up instead of from the ceiling down. That's a real difference in an Adirondack camp with a cathedral ceiling or a Vermont farmhouse with knee walls upstairs, where a high wall unit has nowhere to hang and warm air would pool at the peak.
Multi-flow vanes give it fast cooling in summer too. Compact footprint, easy filter access at standing height, and full Hyper-Heat performance when paired with an H2i® outdoor unit.

Questions about floor-mounted units
Can it go under a window?
Yes — that's the classic placement, right where the baseboard was. It needs a few inches of clearance and a path for the line set through the wall behind it.
Is it as efficient as a wall unit?
Slightly less on paper, but in rooms with high ceilings it often delivers better comfort per dollar because the heat stays where you are instead of at the peak.
Does it get in the way of furniture?
It's about 28 inches wide and 8.5 inches deep — roughly a large radiator. Most people place it where the old radiator or baseboard was and the furniture layout doesn't change.
Can it be recessed into the wall?
It can be partially recessed with a framed opening; we'll look at the wall construction at the estimate.
Can a floor unit be one zone of a multi-zone system?
Yes. Mix a floor unit in the sunroom with wall units in the bedrooms and a cassette in the kitchen on one MXZ outdoor unit.
Is it safe with kids and pets?
The outlets are louvered and the surfaces stay warm, not hot — nothing like a radiator or electric baseboard.
