Room guide
Multi-room air conditioning
If you want to cool or heat more than one room, a multi-split system links two or more indoor units to a single outdoor unit, instead of fitting a separate outdoor unit for every room. It suits homes where several rooms need climate control but there is not space, or budget, for that many outdoor units.
How it is priced
Multi-room systems are not on our fixed price list, because the right setup depends on how many rooms you want covered, how big each one is, and how much total capacity the outdoor unit needs to supply. Every indoor unit on a multi-split system is not priced from our six fixed packages, but the single-room prices on our prices page give you a rough idea of what each room would cost as a single-split job. The whole-system price, including the shared outdoor unit and pipework, is quoted individually rather than from the fixed list.
Multi-split compared with separate single-split systems
| Multi-split (one outdoor unit) | Separate single-split systems | |
|---|---|---|
| Outdoor units needed | One, sized for all rooms combined | One per room |
| Typical use | Two to four rooms used at similar times | Rooms used very differently, or added at different times |
| Pricing | Quoted individually, based on total capacity | Each room priced individually from our fixed list |
| Control | Each indoor unit controlled separately | Each indoor unit controlled separately |
Noise
Indoor noise for a multi-split system depends on which indoor unit goes in which room; the figures are the same as for the matching single-split unit of that model and size, as published on the manufacturer's spec sheet for that model. We cannot give one noise figure for a whole multi-split system, because each room's unit can be a different size.
Running costs
Running cost for a multi-split system depends on how many rooms are in use at once, the size of each room, and how the system as a whole is set up, so we cannot give a single running cost figure here. Electricity is charged at the same Ofgem price cap rate as the rest of your home, whichever rooms you choose to cool or heat.
Which system suits a multi-room job?
Multi-split systems are quoted per home, so which models are available depends on the rooms involved and the outdoor unit that suits them. Our six fixed-price packages are priced as single-split systems. Ask us, and your engineer will talk you through the multi-split options for your home at survey.

Questions about multi-room air conditioning
Short answers to what people ask us most.
All questions answeredWhat is multi-split air conditioning?
It is a system where one outdoor unit connects to two or more indoor units, so you can cool and heat several rooms without an outdoor unit for each one.
How many rooms can one outdoor unit serve?
It depends on the outdoor unit's capacity and the size of each room. We work this out room by room at your free survey, so every indoor unit is sized correctly rather than guessed.
Is multi-split cheaper than separate systems?
Sometimes, because one outdoor unit and one set of outdoor pipework can cost less to fit than two or three separate systems, but it depends on the rooms involved. We quote multi-room jobs individually rather than from a fixed list, so you get an accurate figure.
Can I mix packages across rooms in a multi-split system?
Indoor units on the same outdoor unit generally need to be from a compatible range, so your engineer will talk you through which combinations work before you choose. We check this at survey.
