Ceiling Cassette Air Conditioning
Recessed into the ceiling with only a slim grille on show, cassette air conditioning delivers even, multi-directional cooling and heating without taking any wall or floor space — the discreet, professional choice for offices, shops, restaurants and open-plan rooms.
In short
A cassette air conditioner is recessed into a suspended or plasterboard ceiling, with only a flush grille visible. It distributes air in two or four directions for even comfort across large or open-plan spaces, making it popular for Surrey offices, retail units and restaurants.
Discreet cooling from above
A cassette unit sits within the ceiling void, leaving only a flush decorative grille flush with the ceiling line. Most are four-way blow, pushing conditioned air evenly into all corners of a room from a central point, which is ideal for square open-plan spaces. Two-way and one-way cassettes suit narrower rooms and corridors.
Because the bulk of the unit is hidden, cassettes are the go-to where appearance matters — boardrooms, showrooms, salons and restaurants — and where wall space is taken up by glazing, shelving or signage. They do require a ceiling void (typically a suspended ceiling) deep enough to house the unit and its pipework.
Where cassettes work best
Cassettes shine in commercial and open-plan settings: a single central unit can condition a large area far more evenly than multiple wall units. They are commonly specified for Surrey offices on business parks, retail floors, hospitality spaces and converted commercial buildings with suspended ceilings.
In homes they appear in open-plan kitchen-diners, garden rooms and orangeries with the right ceiling construction. Where there is no ceiling void — a typical pitched-roof room or a solid ceiling — a wall-mounted or ducted system is usually the better fit. We assess the ceiling build-up at survey.
