From a single wall-mounted unit in one room to a VRF system running an entire building, we design, supply and install the right system for the space, not the one that's easiest to fit.
The short version: a split system conditions a room, a ducted system conditions a home or tenancy from out of sight, and a VRF system conditions a whole building.

Split Systems
Split System Air Conditioning
A split system pairs one outdoor unit with an indoor head to heat and cool a single room or open-plan area. It's the most common choice in Melbourne homes because it's efficient, quiet, quick to install and reverse cycle. One unit covers both winter and summer. Where you need more than one room, a multi-split runs several indoor heads from the one outdoor unit.
Wall-mounted, floor, cassette and multi-split units for a single room or a few rooms. All reverse cycle, all Mitsubishi Electric.
Mitsubishi Electric
Wall-mounted
AP Series – Wi-Fi Built-In
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.
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.
“Can not recommend Grotec highly enough. I had my out dated ducted system replaced and can not believe the difference it's made. Super impressed with the service from start to finish.”
