Cool and heat two, three or more rooms from a single outdoor unit. Our F-Gas certified engineers design and install multi-split air conditioning systems for homes across Wiltshire — tidier, quieter and cheaper per room than separate units.
A multi-split air conditioning system connects one outdoor condenser to between two and five indoor units, each in a different room and each with its own controls. If you want split air conditioning units in more than one room — the main bedroom and the home office, say — a multi-split is nearly always the neater and better-value way to do it. We design and fit them across Swindon, Salisbury, Chippenham, Trowbridge and the rest of Wiltshire.
You could fit two or three single split air conditioning systems, each with its own outdoor box on the wall. But most homes don't have — or don't want — a row of condensers outside. A multi-split solves that:
The most common multi-split jobs we do around Wiltshire are a main bedroom plus home office pairing, a whole upstairs (two or three bedrooms off one condenser, so everyone sleeps through a heatwave), and a lounge plus kitchen-diner for open-plan living spaces that overheat on summer afternoons. At your free survey we'll calculate the heat load room by room — our guide to what size air conditioning unit you need explains how sizing works.
The indoor units on a multi-split don't all have to look the same. A discreet wall-mounted unit suits most bedrooms, while a ceiling cassette sits flush in the ceiling of a kitchen-diner or loft conversion where wall space is tight. We regularly combine wall-mounted and cassette units on the same system — whatever suits each room in your home, from a Devizes cottage to a new-build in Marlborough.
Every multi-split we install works in reverse as a highly efficient heat pump, delivering 3–4kW of heat for every 1kW of electricity. That means the same system that keeps the bedrooms cool in July heats them cheaply in January — particularly useful for lofts, extensions and rooms the radiators never quite reach.
A two-room multi-split system typically starts from around £2,800–£3,500 installed, depending on the units chosen and the pipework runs. Three, four and five-room systems are quoted by configuration. We give a fixed, no-obligation quote after a free survey — see our installation cost guide for typical figures.
A domestic multi-split outdoor unit typically runs two to five indoor units, depending on the model and the size of the rooms. At your free survey we do a heat-load calculation for each room and match the outdoor unit's capacity to the total.
No — each indoor unit is independently controlled with its own remote or app control, so you can cool the bedroom at night with everything else switched off. The outdoor unit simply adjusts its output to whatever is running.
Usually, yes. You buy and install one outdoor condenser instead of two, so the cost per room comes down and you only need one external position on the wall. Two rooms on a multi-split typically costs from around £2,800–£3,500 installed.
