How multi-head systems work
A multi-head system connects several compatible indoor units to one outdoor unit. It can be useful where outdoor space is limited or roof space makes ducts impractical. Available combinations depend on the manufacturer's specifications.
Capacity and simultaneous use
Ask how the outdoor unit is sized for the indoor units and how performance changes when several rooms operate together. Many residential systems require connected rooms to share the same heating or cooling mode; confirm the proposed equipment's limitations.
Installation planning
Each indoor unit needs pipework, drainage and an appropriate position. Compare routes, access, electrical requirements and serviceability. Fewer outdoor units do not automatically mean a simpler or less expensive installation.
Compare your alternatives
Ask for a comparison with individual split systems and, where feasible, ducted reverse-cycle air conditioning. Consider the rooms covered, controls, equipment locations, efficiency and future servicing alongside the price.
What happens after I enquire?
Up to 5 participating group related companies receive your details and may contact you to discuss the project. Each company confirms its own availability and installation scope. You compare the proposals and decide whether to proceed.
