Wall-Mounted Split Air Conditioning
A single split system pairs one indoor wall unit with one outdoor condenser, connected by refrigerant pipework.
A single split system pairs one indoor wall unit with one outdoor condenser, connected by refrigerant pipework. It is the most common way to cool one room properly, and most modern units heat as well as cool.
Sizing the room, not the wall
Glazing, orientation, roof exposure and occupancy drive the load. An undersized unit runs flat out; an oversized one cycles and dehumidifies poorly.
The pipe route decides the price of the job
Core drilling, condensate fall and how far the indoor unit sits from the condenser matter more than the badge on the box.
Legal side
Refrigerant handling requires F-Gas competence. We are REFCOM registered, and installations are carried out and documented accordingly.
Practical siting points
- Airflow that is not blowing straight at a seat or bed
- Condensate that can drain by gravity where possible
- Outdoor unit position with clearance and neighbour noise considered

Cool one room properly
Tell us the room size, the window orientation and where the outdoor unit could go and we will size it properly.
Questions we get asked
Can it heat in winter?
Most modern split systems run in heat pump mode and heat efficiently in mild conditions.
How disruptive is installation?
There is a core drill through the wall and pipework to conceal or trunk. We agree routes before starting.
Is finance available?
Finance is available on air conditioning installations subject to status and the terms on our finance page.
