Choosing Your System
Some people come to us with a model number already picked out. Most don't , they're deciding between a split system on the wall and a ducted system hidden in the ceiling. Either way, we'll size it properly at the site assessment before anything is ordered.
Send us the make and model and we'll quote supply and installation, or installation only if you've bought the unit elsewhere. We'll tell you up front if it's the wrong size for the space rather than install something that will underperform.
Almost every residential job comes down to split versus ducted. The comparison below is the honest version. What each one costs you in wall space, ceiling space and disruption, not just what it does well.
Two columns, eight questions. If you need more than a handful of rooms or a whole building zoned independently, there's a third option. VRF, covered on our split system and VRF page.
One room through to a few rooms
One per outdoor unit, or several on a multi-split
A unit on the wall, floor or ceiling
2.0 – 7.8 kW
Each unit controlled on its own
Homes, apartments, small offices, single rooms
One outdoor unit per system
Gets expensive and cluttered past a few rooms
A whole home or tenancy from one hidden unit
One unit feeding ducted outlets in every room
Only the outlets. The unit is hidden in the ceiling
2.5 – 10.0 kW
Zoned by area from one controller
Apartments, houses, tenancies, open-plan offices
One outdoor unit per ducted system
Needs ceiling space, and it's disruptive to retrofit
We're a Mitsubishi Electric dealer, and we also install Daikin, Panasonic, Hitachi and Temperzone. These are the Mitsubishi Electric residential and light commercial units we fit most often.
Wall-mounted, floor, cassette and multi-split units for a single room or a few rooms. All reverse cycle, all Mitsubishi Electric.
Wall-mounted
The core wall-mounted range, in seven capacities from a small bedroom through to a large open-plan living area. Wi-Fi is built in, so you can start it before you get home.
Wall-mounted
The smallest unit in the AP range, for a single bedroom, study or small office where 2.0 kW is plenty.
Designer wall-mounted
The designer range in a brushed Onyx Black finish, for living rooms and bedrooms where the unit shouldn't be the first thing you notice.
Designer wall-mounted
The same designer body in Ruby Red, a deliberate feature rather than something to hide, with the same performance as the rest of the LN range.
Floor console
A floor console that sits low like a heater, for rooms with no usable high wall. Under windows, in extensions, and in homes moving off gas.
Wall-mounted
The 2.0 kW AP wall unit supplied as a complete indoor and outdoor kit, with Wi-Fi control included.
Designer wall-mounted
A 2.5 kW designer unit with a flat, glossy face, for bedrooms and studies where wall space is tight and looks matter.
Compact ceiling cassette
A compact cassette recessed into the ceiling and blowing in four directions. For open-plan areas, retail and offices where a wall unit would look out of place.
Multi-split outdoor unit
A two-port outdoor unit running two indoor heads, so you can do two rooms without a second box on the wall outside.
Victorian Energy Upgrades
The VEU program helps eligible households and businesses replace old heating with efficient reverse-cycle air conditioning, lowering the upfront cost of your installation.
