Comfort Systems helps Perth homeowners compare split, multi-split and ducted air conditioning for bedrooms, living areas, multi-room layouts and whole-home comfort — with heating and cooling options for existing homes, renovations and new builds. For local service information in Perth's south, see our air conditioning Rockingham page.
Start with the rooms, layout and installation conditions before narrowing the equipment.
A useful residential air conditioning conversation starts with the property: how many spaces need conditioning, how those rooms are used, where indoor and outdoor equipment can go, and whether you prefer visible room units or a more concealed whole-home approach.
One bedroom, a living zone, several separate rooms or the majority of the home lead to different system categories.
Open-plan areas, separated rooms, ceiling space and installation access affect what is practical.
Wall-mounted units are visible; ducted systems place the main indoor equipment and ductwork largely out of sight.
Renovations, added rooms or a new-build stage can change where services and equipment can be planned.
These are system categories rather than one-size-fits-all recommendations. Exact capacity, controls and installation requirements depend on the selected equipment and property.
A split system commonly pairs one wall-mounted indoor unit with one outdoor condenser. It is often considered for a bedroom, living area, home office or another defined space that needs its own heating and cooling.

A compatible multi-split system can connect several indoor units to one outdoor unit. This can suit homes that need independent conditioning in several rooms while reducing the number of outdoor condensers compared with separate single-split systems.
Explore Multi-Split Air Conditioning →Ducted air conditioning uses a central indoor unit and concealed ductwork to distribute conditioned air through outlets across selected areas. For suitable homes, it provides a low-visibility route to multi-room or whole-home heating and cooling.

Existing homes need solutions that work around finished spaces. Renovations can open new routes for equipment and services. New builds offer the greatest opportunity to discuss air conditioning before ceilings, walls and service paths are finalised.
Work with the layout, access and available indoor and outdoor equipment locations.
Coordinate the air conditioning approach with room, ceiling and wall changes where practical.
Discuss system format, equipment space, duct paths and outlet locations earlier in the project.
Consider available outdoor-unit space and any building or strata requirements that apply.
Comfort Systems works with three manufacturers that currently offer residential heating and cooling products in Australia. The appropriate product family depends on system type, room requirements and current availability.
Daikin Australia's Alira X is a current residential split-system range available in reverse-cycle and cooling-only configurations, with multiple capacities listed by Daikin.
MHIAA's Bronte series is part of its current Australian wall-mounted split-system range and is offered in higher-capacity residential models for larger spaces.
Midea Australia currently lists EOS models within its residential split-system range, alongside other residential air conditioning product families.
Capacity and system format need context. Room dimensions matter, but so do construction, orientation, insulation, occupancy, glazing, layout, usage and installation conditions.
Conditioning one room is a different problem from conditioning four rooms or an entire home.
Insulation, glazing and construction can influence heat gain and heat loss.
Indoor airflow and outdoor-unit placement both need practical installation positions.
Depending on the product, options can include scheduling, Wi-Fi, individual indoor-unit control or zoning.
Bedrooms, living areas and home offices can have different operating times and comfort requirements.
Use this as a category-level guide only. Exact capabilities and installation requirements vary by model, manufacturer and property.
No universal system is best for every property. The useful answer starts with the application.
There is no single best format for every home. Split systems are commonly used for individual rooms, multi-split systems can serve several compatible indoor units from one outdoor unit, and ducted systems can provide concealed distribution to multiple areas. Property layout and requirements determine which category is worth exploring.
Yes. Reverse-cycle air conditioning can provide both heating and cooling. The exact operating modes, capacity and efficiency depend on the selected system and model.
A split system normally has a visible indoor unit serving a room or defined area. Ducted air conditioning uses a central indoor unit and concealed ductwork to distribute conditioned air to multiple outlets.
Discussing air conditioning earlier can make it easier to consider equipment space, outlet locations and service routes while the building design is still flexible. The appropriate timing depends on the builder and project program.
Comfort Systems works with Daikin, Mitsubishi Heavy Industries Air-Conditioners and Midea. Product suitability depends on the system type, application and current Australian range.
Tell Comfort Systems which rooms need heating or cooling, whether the home is existing, being renovated or still in design, and how discreet you want the finished system to be. That creates a clearer starting point for the right residential air conditioning conversation.
