Split & Multi-Split Systems done right

A split system is the cost-effective way to heat and cool a single room or living area. Need a few rooms covered from one outdoor unit? A multi-split does exactly that. We recommend the right size and brand for the space and install it cleanly, with the cabling and brackets done properly.

The detail

Choosing between a split system and a multi split

A split system is the most cost effective way to heat and cool one or two rooms. A multi split runs several indoor heads from a single outdoor unit, which is useful when there is only one sensible place to put that outdoor unit. The right answer usually comes down to how many rooms you need and where the pipes can run.

  1. Room sizingCapacity is matched to the room, allowing for glazing and orientation. An oversized unit short cycles and does not dehumidify properly, an undersized one runs flat out and never quite gets there.
  2. Indoor head placementThe head needs a clear path to push air across the room, and it needs to be somewhere the airflow is not blowing directly at where you sit or sleep.
  3. Outdoor unit placement and the pipe runA back to back installation, where the outdoor unit sits directly behind the head, is the simplest and cheapest. Longer pipe runs, upper storeys and awkward access all add to the job.
  4. Single versus multi splitMulti splits save outdoor space and suit apartments or homes with limited wall room. The trade off is that all the heads share one outdoor unit, so if it needs attention every room is affected at once.
  5. Electrical, mounting and commissioningWe confirm the circuit, mount and bracket both units, pressure test and evacuate the lines, then commission and check the operation before we leave.

Common questions

Should I get one multi split or several single splits?

If the rooms are spread out and there is outdoor space, separate single splits are usually cheaper and more robust because each room is independent. Multi splits win when outdoor space or wall access is genuinely limited.

What size split system do I need for my room?

It depends on the floor area, the glazing, the ceiling height and which way the room faces. We size it at the quote rather than selling you a number off a chart.

Where can the outdoor unit go?

It needs clear airflow and sensible clearance, and we consider noise toward bedroom windows and boundaries. On most homes there are two or three workable options.

How long does a split system installation take?

A straightforward back to back installation is usually a few hours. Longer pipe runs or upper storey placements take most of a day.

"We have had Efficient Air install 4 Hisense reverse cycle units over the last 12 months. Each time had been a trouble free experience. Jason and Kelly have been great to deal with. The installation crews have been on time and completed their work without fuss."

"I have always had a great experience when needing services and products from Efficient Air. I have had split systems and radiators from them and the service has been very good. The split system keeps us cool in summer and warm in winter which is what we need right now in Melbourne!"

Setting a home air conditioner to 21 degrees with a wall-mounted split system running in the background

Will your place cope with the first 38 degree day?

Four things worth checking now, while there is still time to do something about them. Two of these are a service, not a new system, and we will tell you which one you are looking at.

  • It struggles once the day passes 35 degrees.A system that cools fine in spring but never quite gets there in a heatwave is usually undersized for the space rather than faulty.
  • Some rooms never cool down.Normally a zoning or ductwork problem, not a reason to replace the whole system. Worth having someone look before you spend.
  • It has not been serviced since last summer.Filters and coils that have sat through winter are the most common reason a system underperforms on the first hot day.
  • It is more than ten years old.Older units lose capacity and cost more to run each summer. That is the point where replacing can be cheaper than another repair.
