Mitsubishi Ceiling Cassettes & Ceiling-Suspended Units
Ceiling-mounted units put the heat and cooling overhead and keep the walls clear. Mitsubishi makes three: the MLZ EZ FIT one-way cassette that slips between standard joists in a kitchen or hallway ceiling, the SLZ and PLA four-way cassettes that recess flush into a drop ceiling or framed opening and throw air in four directions across a great room or an inn's dining room, and the PCA ceiling-suspended unit for restaurants, classrooms and shops with hard ceilings. All run on Hyper-Heat outdoor units and all are installed and serviced from our Ticonderoga shop.

Precise comfort control
How a ceiling cassette works
A cassette sits inside the ceiling with only a slim grille showing. Room air returns through the center of the grille, passes the coil and fan inside the ceiling, and comes back out through one or four adjustable outlets around the edge. A return-air sensor on every unit watches the room and asks the outdoor unit for exactly the capacity it needs; the vanes let you aim air where it's wanted and away from a dining table or a desk. Because the unit is overhead and central, coverage of a large open room is more even than from any single wall unit, and there's nothing on the walls at all.
- Washable filters accessed from below through the grille — no attic trip, nothing to buy
- Auto vane and, on SLZ, PLA and PCA, an optional 3D i-see sensor that directs air toward or away from people
- Condensate pump built in, so cooling drain lines can run up and out
- Single-zone or multi-zone on SUZ, PUZ or MXZ Smart Multi outdoor units

Placement in North Country buildings
Where ceiling units go, and what the ceiling needs
- 1800s village kitchens: the MLZ EZ FIT fits between joists below an unfinished upstairs floor or an accessible attic. We cut one rectangular opening, run the line set through the attic or a closet, and the grille is the only thing you see.
- Great rooms with a flat ceiling and attic above: SLZ four-way, centered, for even coverage of the whole room from one unit.
- Cathedral ceilings: usually no cavity, so a cassette won't fit — a floor-mounted unit or wall unit instead.
- Inns, dining rooms and offices with drop ceilings: PLA in a 2'x2' tile location; one unit can cover a large room.
- Restaurants, classrooms and shops with hard ceilings: PCA suspended, which needs no cavity at all.
Access from above or a nearby closet for the line set and drain is the first thing we check at the free estimate.
Air quality, controls and maintenance
Ceiling cassettes use the same washable filter approach as every Mitsubishi indoor unit: drop the grille, slide the filter out, rinse, dry and reinsert. Nothing to buy, nothing to order. Filtration keeps dust, pollen and pet hair out of the coil, and some models can bring in a measured amount of fresh outdoor air. Controls include the standard wireless remote, the MHK2 wall thermostat, PAR wired controllers for commercial rooms, and the Mitsubishi Comfort or kumo cloud app so an innkeeper can set every room from a phone. Annual service — coil and blower cleaning, drain pump check, charge verification — is part of the Elite Care Plan or our maintenance menu. See controls for the full lineup.
Ceiling unit questions
Questions about ceiling-mounted units
Will a ceiling cassette fit in my house?
The MLZ EZ FIT is designed for standard 16-inch joist bays under an accessible attic or floor, which covers most North Country homes with flat ceilings. SLZ and PLA need a deeper cavity or a drop ceiling. Cathedral ceilings usually can't take a cassette; we use floor or wall units there.
Do ceiling cassettes work with Hyper-Heat?
Yes. On H2i outdoor units, cassettes deliver 100% of rated capacity at 5°F and operate to -13°F. The heat comes out of the ceiling vanes and the vanes aim it down into the room.
Does heat from the ceiling actually warm the floor?
Yes, when the vanes are set to throw downward in heating mode, which the unit does automatically. In a standard-height room the air mixes well. In very tall rooms we usually recommend a floor-mounted unit instead.
How do I change the filter?
Open the grille from below, slide the washable filter out, rinse and dry it, and slide it back. No ladder into the attic, no filters to buy.
Where does the condensate go in summer?
Cassettes have a built-in lift pump, so the drain line can run up and over to an exterior wall or a drain. We route it at install and check the pump at every annual service.
Can one cassette cool a whole restaurant or inn dining room?
A PLA four-way cassette up to 42,000 BTU/h often can. Larger spaces use two or more cassettes on a multi-zone or P-Series outdoor unit. We size from a load calculation at the estimate.
