Wall-mounted (the default)
The familiar unit high on the wall. It's the most common for a reason: lowest cost, highest efficiency, simplest install, and the widest model selection. If you don't have a specific reason to choose another type, this is it. The only downsides are aesthetic (it's visible) and placement (you need suitable high wall space). Nearly all of our best mini splits picks are wall units.
Ceiling cassette (the discreet one)
Recesses into the ceiling with only a flush grille showing, blowing air in four directions for even coverage - great for larger or square rooms and for anyone who doesn't want a unit on the wall. The tradeoffs: it needs open space above the ceiling (attic or a dropped ceiling), it's a more involved, pricier install, and there are fewer models. Best for open-plan spaces and clean-look renovations.
Floor / console (the low-mount one)
Sits on the floor or low on the wall, like a radiator. Choose it when you can't mount high - rooms with big windows, cathedral or sloped ceilings, knee walls, or all-glass walls. It's also easier to reach for cleaning, and low placement can feel better for heating (warm air rises from the floor). Common in additions, sunrooms, and older homes.
Short-duct / concealed (the hidden one)
A slim air handler hidden in a ceiling, soffit, or closet that pushes air through short duct runs to one or a few rooms via normal-looking vents - no visible indoor unit at all. It bridges ductless and ducted: the invisible look of central air with the zoning and efficiency of a mini split. More install work and design, but the cleanest appearance.
Which type should you choose?
- Default / best value: wall-mounted.
- Don't want a visible unit, have ceiling space: ceiling cassette.
- No high wall space, big windows, or heating-focused: floor/console.
- Want it completely hidden / feeding a couple rooms: short-duct concealed.
Whatever the shape, size it to the room first with the size chart and sizing guide, and decide how many zones you need in how many zones do I need. The efficiency and heat-pump operation are the same across all of them - see how mini splits work.
FAQ
What are the different types of mini splits? By indoor unit: wall-mounted (the default), ceiling cassette (recessed, four-way airflow), floor/console (low-mount), and short-duct concealed (hidden, ducted to vents). All use the same heat-pump technology.
Which mini split type is best? Wall-mounted for most people - cheapest, most efficient, easiest. Choose a cassette for a discreet ceiling look, a floor unit when you can't mount high, or concealed ducted to hide the equipment entirely.
Are ceiling cassette mini splits worth it? If you want even four-way airflow and no wall unit - and you have space above the ceiling - yes. They cost more and have fewer models, so they're a look-and-coverage choice, not a value choice.
What is a floor-mounted mini split good for? Rooms where you can't mount high
- big windows, sloped or cathedral ceilings, knee walls - and heating-focused spaces, since warm air rises from the low unit. It's also easy to reach for cleaning.
