Wall hung split systems, otherwise known as reverse cycle, are a very flexible and adaptable product which can provide both heating & cooling. Best of all, when ducted systems are not an option due to a lack of ceiling or underfloor space, a wall hung split system will get the job done with a simple no fuss installation.
Ducted systems are designed to cool entire homes and can be installed in new or existing houses. Typically, the cooling fan coil is mounted in the roof and the cool air spreads around the home through a network of ducts. Once installed, only the grilles, return air and controller are visible in the home.
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.
Bulkhead units are generally designed for houses in which there is limited roof space for a ducted air conditioning system and those people who would prefer an air conditioning system that's basically unseen. Bulkhead air conditioning units fit into the ceiling space of any room and the only sign it exists is the discharge grill in the roof or wall.
