As the name suggests, ceiling cassette units are mounted in the ceiling and distribute conditioned air through two, three or four sides of the unit. The outdoor unit of a cassette air conditioner is mounted outside, in the same way as it would be for a conventional split air conditioner unit. Most consumers don’t even think of getting a ducting system or a cassette AC. But this is changing now. Today, many homeowners are starting to prefer cassettes air conditioner over conventional AC units.
The performance of cassette units is generally comparable to that of other types of systems, although because they’re most commonly installed in commercial or office areas, they tend to be more powerful than wall-mounted systems. They are particularly well suited to circumstances where wall-hung split systems or other system types might not be an option. Cassette units tend to be more expensive than other systems.
