Split System Air Conditioning Installation In Melbourne

Split Systems Installed Properly

A split system should be sized properly, positioned sensibly, wired safely and commissioned correctly. We help with single split and multi-split installations for bedrooms, living areas, apartments, townhouses and small offices.

We can install customer-supplied units, or help arrange a suitable unit as part of the installation. Where required, we can also complete the electrical side, including circuit protection, isolator installation and switchboard upgrades.

Customer-Supplied Or Supply And Install

If you already have a split system, we can install it provided it is suitable for the room and the site conditions.

If you want supply and install, we can help recommend a suitable Daikin or Mitsubishi model based on room size, ceiling height, glazing, insulation and sun exposure.

Approximate Sizing Guide

Up to 15 m² — around 2.0 to 2.5 kW for bedrooms or small offices

15 to 25 m² — around 3.2 to 3.5 kW for larger bedrooms or small living areas

25 to 35 m² — around 4.6 to 5.0 kW for medium living areas

35 to 50 m² — around 6.0 to 7.1 kW+ for larger open-plan spaces

Actual sizing depends on insulation, windows, ceiling height, room layout and sun exposure. We’ll confirm what is suitable before installation.

Important Things To Know

Back-to-back installs are usually the simplest and most straightforward.

Longer pipe runs or difficult access can affect the installation scope.

Some installs require extra electrical work such as a dedicated circuit, RCBO protection or switchboard upgrade.

Outdoor unit placement matters for airflow, noise, access and neighbour considerations.
