Cassette units work the same way as wall-hung split system units, with the difference being that cassettes are installed into the ceiling instead of on the wall. The indoor unit itself sits flush to your ceiling and distributes conditioned air through two, three or four sides of the unit. Cassette air conditioners are one of the best because they can be installed in various rooms such as apartments and offices. Installation is most often on the ceiling and makes them especially suitable if you have a suspended ceiling, as there is enough space for installation. Like other split units, they have an outdoor unit that transports the refrigerant to the indoor air handling blower via a conduit. They provide ample airflow from the four openings on each side of the unit.
Given the fact that the cold air falls and the hot air rises in the room, one of the main advantages of the cassette air conditioners is that they ensure a good distribution of air in the room.

It's Ideal for Small Spaces
If you live in an apartment or work in a small office, a ceiling cassette system is a good choice. That's because it doesn't crowd you by taking up needed space. It doesn't protrude from your window ledge like a window unit or jut out of the wall like a wall-mounted unit.
