What affects the price
- The number and size of rooms
- The pipe runs from each room to the outdoor unit
- Which floors the rooms are on
- The unit range you choose
How long it takes. A multi-room system usually takes one to two days, depending on the pipe runs.
How it works in your home
A multi-split system connects two or three indoor units to a single outdoor unit. Each room has its own unit and its own controls, so a bedroom can be cool at night while the living room is off, and there is only one outdoor unit on the wall instead of several.
Dexter sizes each indoor unit to its room and how much sun it gets, then chooses an outdoor unit to match. The price tool lets you add rooms one by one and shows the multi-room saving straight away.

your questions
Not sure what boiler you have? Send Dexter a photo and he will tell you.
WhatsApp DexterHow many rooms can one outdoor unit serve?
The price tool designs systems of up to three rooms on one outdoor unit. Ask Dexter about larger homes.
Can each room be a different temperature?
Yes. Each indoor unit has its own controls.
Do all the rooms have to be on the same floor?
No, although rooms on higher floors can add to the pipe run.
Can I add a room later?
It is best to plan all the rooms at once, because the outdoor unit is sized for the whole system.
