Multi-split air conditioning in Harlow
Want three bedrooms cooled without three boxes on the wall? A multi-split runs several indoor units off one outdoor unit, each set to its own temperature. Houses and small offices in Harlow and nearby use them for a top floor, an office suite or most of a home.

How does a multi-split work?
Think of a hub and spokes. The outdoor unit is the hub, and a separate pair of refrigerant lines runs out to each room. Energy Saving Trust webinar material describes systems up to 12kW with as many as five indoor units, and larger ranges are made. A room nobody is using can simply stay off.
Why the planning rules favour a multi-split
Permitted development allows one outdoor unit on a terraced or semi-detached house and two on a detached one. So for three bedrooms on a semi in Harlow, this may be the only route that avoids an application. It also saves space on a narrow side return or a short back wall.
Single systems have a case too. When one breaks, the others carry on, and you can replace each by itself. For two rooms at opposite ends of a house, a pair of singles can be simpler. If it is close, we price it both ways.
How do the pipes get back to one place?
This is the hard bit. Having a loft makes a top floor far easier, because lines can cross it and then drop inside a cupboard or down an outside wall. Every model caps the total pipe run and the rise between units, so planning starts at the outdoor unit and works back towards the rooms. Going across floors is possible, but it takes more thought.
What changes the price of a multi-split?
Each added room brings another indoor unit, a controller and a pipe run, and the outdoor unit grows to match. Route has the largest effect: crossing a loft is much cheaper than boxing in lines over two floors. It also helps to know which rooms you would run at once, as that sets the capacity. The size guide helps with each room.
Questions people ask
Can one room heat while another cools?
Not on a standard multi-split, because all the indoor units share one mode. Doing both at once takes a larger commercial system.
What if the outdoor unit breaks down?
Every room on it stops until the repair is done. Separate single systems avoid that, which is the trade-off.
Could I do two rooms now and more later?
Usually, provided the outdoor unit has spare capacity and connections. Mention it at the start, because allowing for it now is far cheaper than changing it later.
Does a bigger system need legal leak checks?
It does from 5 tonnes of CO2 equivalent, roughly 7.4kg of R32, and then at least yearly. Few home systems hold that much. The F-gas guide explains.
