How ceiling cassette systems work
A ceiling cassette is the indoor part of a split or multi-split system. The unit sits within the ceiling void with only a slim decorative panel visible. It draws air in through the centre and distributes it through adjustable louvres on up to four sides, giving wide, even coverage without the draughts you can get from a single direction.
Ideal applications
Commercial
Open-plan offices, shops, showrooms, restaurants, cafés, gyms, clinics and classrooms.
Residential
Large kitchen-diners, open-plan living areas, garden rooms and home cinemas with suitable ceiling voids.
Compared with wall-mounted units, cassettes provide wider air distribution and keep walls clear for shelving, displays or artwork. They do need a suitable ceiling void, which we confirm during the survey.

Installation and timescales
We survey the ceiling void, structure and access, then install the cassette, refrigerant pipework, condensate pump and controls with minimal disruption. Most single-cassette installations take one to two days; larger commercial projects are scheduled around your working hours.
Maintenance, controls and warranties
Cassettes can be linked to central controllers or building management systems, with scheduling and zoning to manage energy use. Regular servicing – including filter cleaning, condensate pump checks and coil cleaning – keeps them hygienic, efficient and covered by warranty.
Four-way, one-way and compact cassettes explained
Four-way cassettes
The most common type, spreading air in all directions from the middle of a room.
One-way and two-way cassettes
Fitted near a wall or window to push air across narrower spaces such as corridors and shopfronts.
Compact cassettes
Sized to fit standard suspended-ceiling grids – popular in offices and classrooms.
Ceiling cassette or wall-mounted unit for an office?
Cassettes give wider, more even coverage and keep walls clear, making them ideal for open-plan floors with suspended ceilings. Wall-mounted units are quicker and cheaper to install in smaller, solid-ceiling rooms. Many offices use both.
