Multi-Split Air Conditioners
A multi-split system drives two to five indoor units from a single outdoor condenser, so several rooms get independent air conditioning without cluttering the outside of your building with multiple compressors.
It's the cleanest solution for multi-bedroom homes, home offices and small commercial spaces — one quiet outdoor unit, per-room zoning, and a single installation visit.
Professional installation required
These units must be fitted by a certified F-gas engineer. Use our free installer-matching service to find a vetted local engineer.
Why choose a multi-split air conditioner
- One outdoor unit for up to five rooms — less exterior clutter and noise
- Independent zoning — heat or cool each room on its own schedule
- More efficient than several single splits sharing outdoor space
- Single F-gas installation visit via Stockool's matched installer network

Multi-Split Air Conditioners — frequently asked
How many rooms can one multi-split outdoor unit run?
Most domestic multi-split systems drive between two and five indoor units from a single outdoor condenser. Some commercial models support more — check the product spec or use our BTU calculator to size a system for your rooms.
Is a multi-split more efficient than several single splits?
Generally yes. One inverter compressor serving multiple zones uses less energy and frees up outdoor space, and zoning lets you switch off rooms that aren't in use rather than cooling the whole property.
How long does installation take?
A multi-split is a single, longer installation visit rather than several — one qualified F-gas engineer runs pipework to every indoor unit. Stockool matches you with a local installer to quote and schedule it.
