Split System Air Conditioner Installation in Sunbury

Split system air conditioners are the most popular form of home climate control in Australia, and for good reason. They are energy-efficient, quiet, and effective at both cooling and heating a space. A quality split system installed in the right location makes a room genuinely comfortable year-round without the running costs of older or less efficient systems.

Norris Electrical installs split system air conditioners for homes and businesses across Sunbury and surrounding areas. We handle the full installation including the dedicated electrical circuit, the indoor and outdoor unit mounting, refrigerant line connection, and commissioning.

  • All major brands including Daikin, Mitsubishi Electric, Fujitsu, Panasonic, Hitachi, Samsung, and LG
  • Single room and open-plan installations
  • Multi-head split systems (one outdoor unit, multiple indoor units)
  • Like-for-like replacements
  • Supply and install or install-only

Best Placement for Your Split System

Where you position the indoor unit has a big impact on both performance and aesthetics. Norris Electrical advises on the best location for every installation:

  • High on the wall – Split systems are designed to be installed high on a wall for optimal airflow distribution across the room. Mounting too low reduces effectiveness.
  • Away from direct sunlight – The indoor unit’s temperature sensor should not be in direct sun, which can cause the system to under or over-cool.
  • Central to the space – The unit should be able to distribute air across the full area of the room, not just one corner.
  • Outdoor unit placement – The outdoor unit needs adequate airflow clearance, should be away from bedroom windows where possible, and must be accessible for servicing.

Choosing the Right Split System

Getting the right size split system for your space is one of the most important decisions in the installation process. Norris Electrical helps clients choose the right system every time:

  • Capacity – An undersized system runs constantly and cannot reach the set temperature. An oversized system cycles on and off too frequently and is less efficient. We calculate the right kW capacity for each room based on size, insulation, ceiling height, and other factors.
  • Energy efficiency rating – Modern split systems have star ratings for both cooling and heating. Higher star ratings mean lower running costs. For a system that will run many hours a day, investing in a higher-rated model pays off over time.
  • Inverter technology – All modern split systems use inverter technology, which continuously adjusts compressor speed rather than switching on and off. This is far more efficient than older on/off systems.

Our Split System Installation Process

1.

Capacity calculation and system selection
We calculate the correct kW capacity for your room based on size, insulation, and other factors, then recommend the most suitable model for your budget and efficiency goals.

2.

Dedicated circuit installation
A dedicated circuit is run from the switchboard to the indoor unit location, including correctly rated cabling, an isolator adjacent to the outdoor unit, and safety switch protection at the board.

3.

Indoor and outdoor unit installation
The indoor unit is mounted on the wall at the correct height and position. The outdoor unit is secured and positioned with adequate clearance. Refrigerant lines, condensate drain, and control wiring are run and connected between the two units.

4

Commissioning and handover
The system is commissioned, refrigerant levels are checked, and a full test run is carried out in both cooling and heating modes. We walk you through the remote control functions and recommend a servicing schedule before we leave.

Electrical Requirements for Split System Installation

Every split system installation involves electrical work that must be carried out by a licensed electrician. Norris Electrical includes all of the following as standard in every installation:

  • Dedicated circuit – A dedicated circuit from the switchboard to the indoor unit location ensures the system has reliable, correctly rated power.
  • Correct cable sizing – The cable must be rated for the maximum current draw of the installed unit.
  • Isolator switch – A weatherproof isolator switch is installed adjacent to the outdoor unit as required by Australian standards.
  • Safety switch coverage – The new circuit is protected by a safety switch at the switchboard.

If your switchboard is already near capacity or does not have space for a new circuit, we will advise on this during the quote stage so there are no surprises on installation day.
