Not every home suits a ducted system, and not every family wants multiple outdoor units on external walls.
A multihead split system is often the right solution when you want to air condition several rooms, but still keep the outside of the home clean and uncluttered. It is especially popular in homes with limited outdoor space, renovation projects, double-storey layouts, and households that want room-by-room control.
Instead of installing one outdoor unit for each room, a multihead system connects several indoor units to a single outdoor unit. As a result, you can enjoy targeted comfort in the rooms you use most, while maintaining a cleaner exterior finish.
Many homes need heating and cooling in more than one room — but standard solutions don’t always suit the layout.
