Install a Ceiling Cassette Air Conditioning Units

Ceiling cassette air conditioning units are mounted, as the name suggests, in the ceiling. They are most effective installed in a suspended ceiling where there is room to accommodate the unit. Ceiling mounting provides excellent coverage and can cover a fairly large room. Being in the ceiling also means this type of air conditioning system is discreet and out of the way.

How it works

Ceiling cassette units are installed within a suspended ceiling. Traditional air cooled units are connected to an outdoor condenser unit which releases the warm air taken from within the building. Internal water cooled air conditioning units are plumbed into your water supply and use water in a controlled manner to provide cool air. They are an ideal solution for restricted buildings where an outside condenser is not allowed.
