Split or multi-split: which to choose?

A split cools one room with its own outdoor unit; a multi-split connects several indoor units to a single outdoor unit. Here is what to weigh up.

How each one works

If there is little space on the façade or terrace, or the building limits outdoor units.
To air-condition several rooms with just one unit visible outside.
When you prefer a single outdoor unit to maintain.
If you also want to add hot water to the same system.

If the outdoor unit fails, the whole home is left without service.
The indoor units share the capacity of the outdoor unit, so the sizes must be worked out carefully.
The distance between the outdoor unit and each indoor unit has limits.
It is not always cheaper than several splits: it depends on each case.

Before deciding, we look at the home: rooms, use and available space. We recommend the option that fits you best, whether split or multi-split.

How many indoor units can a multi-split take?

It depends on the model: in home systems, between two and four indoor units.

Can I combine wall units with cassette or ducted units?

In many systems, yes. It depends on the outdoor unit chosen, and we check it when preparing the quote.

Can I have cooling in one room and heating in another?

Each indoor unit is controlled separately, but in a standard multi-split they all run in the same mode at the same time: all cooling or all heating.
