The system

What is a split system?

A split system has an indoor unit on the wall and an outdoor unit outside, connected by insulated pipes.

It heats and cools one room efficiently and is often the right first step when a gas space heater is replaced.

The mistakes with split systems are sizing and placement:

  • Too large and it switches on and off constantly.
  • Placed for convenience and it blows on the sofa and misses the rest of the room.

We measure the room and stand in it before quoting.

Installed prices depend on the unit size, pipe run and electrical work; your written quote lists each.

How it works

How does a
split system work?

  • Cooling: the indoor unit draws warm room air across a cold coil and returns it cooled, while the outdoor unit releases the heat outside.
  • Heating: the cycle reverses and the outdoor unit draws heat from outside air, even on cold mornings.

7 to 9 kWOpen-plan living

Large living, kitchen and dining areas.

Running costs

Running costs
and how to lower them

A correctly sized inverter system adjusts its speed instead of switching on and off, which keeps running costs down. The rest comes down to how it is used.

  • Cool to 24 to 26 degrees and heat to 18 to 21 degrees; each degree further adds roughly 10 percent
  • Use zones or close doors so you only condition the rooms you use
  • Close curtains and blinds on hot afternoons
  • Keep filters clean and service once a year
  • Improve ceiling insulation where you can

At the assessment we estimate running costs for your home so you can compare options properly.

Our process

How we work

01

We listen first

Which rooms are uncomfortable, how the house is used, what is installed now and when you need a decision.

02

We measure your home

Room sizes, insulation, roof space, existing ductwork, switchboard capacity and the best outdoor unit position.

03

We explain your options

Usually two or three, with what each costs to run and which one we would choose for your home.

04

You get a clear, written quote

Equipment, inclusions, exclusions, any discount and your final price. No pressure to decide on the day.

05

Installed carefully, cleaned up after

You know who is coming and when. Handover ends with the controller in your hand and the paperwork in your inbox.

Questions

Frequently asked questions
about split system installation

What size split system do I need?

It depends on the room size, ceiling height, insulation and windows. We measure the room and the quote states the capacity and why.

How long does installation take?

Usually half a day for a standard installation with the outdoor unit close to the indoor unit. Longer pipe runs or switchboard work add time, and the quote says so.

Can I add more rooms later?

Yes. We plan placement and electrical work so further splits, or a move to multi-head, are straightforward.

Is a split system eligible for the Victorian Energy Upgrades discount?

It can be when it replaces an eligible gas space heater. We confirm at the assessment.
