Multi-Head Split System Installation in Grafton

A multi-head system runs two to five indoor units from a single outdoor condenser. It is the middle ground between splits and ducted, and it is the right answer surprisingly often around Grafton — particularly in split-level homes around Maclean, in places with no usable roof space, and in homes where there is only one sensible spot for an outdoor unit.

When multi-head beats the alternatives

Against individual splits. one outdoor unit instead of four. That matters a great deal if your house has one viable condenser location, if you are on a narrow block where four units would be a noise problem for the neighbours, or if you simply do not want four boxes on the side of the house.

Against ducted. no roof space required, lower installation cost, and each room controls itself independently. On a split-level home where the roof space changes height across the house, multi-head frequently delivers a better result than ducted for less money.

The honest downside. everything depends on the one outdoor unit. If it fails, every room is affected at once. Individual splits fail independently. It is a real trade-off and worth weighing rather than glossing over.

Getting the design right

Multi-head systems are less forgiving than splits, and most disappointing multi-head installs are design failures rather than equipment failures.

• Total capacity must suit the actual combined load, not the sum of what each room would need alone. Most manufacturers allow some diversity because rooms are rarely all at peak simultaneously — but there are limits, and exceeding them means the system underperforms whenever several heads run together.
• Individual head sizing still matters. A head that is too large for its room short-cycles and never dehumidifies, exactly as an oversized split would.
• Pipe run lengths are limited, both individually and in total. A room at the far corner of the house may simply be out of reach.
• Most multi-head systems cannot heat and cool simultaneously. If one room wants heating and another wants cooling on the same day, one of them loses. Worth knowing before you buy, not after.
