Whole-house air conditioning

Whole-house air conditioning brings comfortable temperatures — and, with a reversible system, efficient heating — to every room, rather than cooling one space at a time.

Two common approaches

• Multi-split — several indoor units run from one or two outdoor units, each room controlled independently. Flexible and widely used for whole-home coverage.
• Ducted — concealed ductwork delivers air through discreet grilles, keeping walls clear. Best planned into a renovation or larger project.

Planning a whole-home system

Whole-house projects benefit from a proper design: room-by-room cooling needs, outdoor-unit positions and pipe routes. Expect a higher investment than single-room work — see the cost guide — and an installer survey to confirm the layout.

Start with the system finder for a preliminary steer, or request an installer match.
