Split Air Conditioning Systems
A split system is the most common and straightforward form of air conditioning — one indoor unit (usually wall-mounted) paired with one outdoor condenser unit, connected by insulated refrigerant pipework and electrical cabling. It’s called “split” because the noisy compressor component lives outside, leaving the indoor unit quiet.
How it works
The indoor unit draws warm room air across a cold coil, removing heat and moisture before circulating the cooled air back into the room. The absorbed heat is carried via refrigerant to the outdoor unit, where it’s expelled outside. Most modern split units are reversible heat pumps, meaning they can run the process backwards to provide heating too.
Best suited to
Single rooms — bedrooms, home offices, living rooms
Small shops, cafés, and single-room commercial units
Situations where a fast, low-disruption installation matters
Budget-conscious projects where only one space needs cooling
Limitations
Each additional room needing cooling requires its own separate outdoor unit unless you move to a multi-split system instead — which can quickly become visually cluttered and more expensive than a single multi-split installation covering the same rooms.
Typical installation time
A straightforward single split installation in an existing property, with a reasonably short pipe run to the outdoor unit, is often completed within a day.
