You don't have a hot house.
You have three hot rooms.

The lounge is arctic by 2pm. The west-facing bedroom is still unusable. Ducted with MyPlace IQ gives every room its own setting — so you stop cooling the whole house to fix one part of it.

Why zoning changes the answer

One thermostat can't run six different rooms.

A standard ducted system has one setting for the whole house. The room catching afternoon sun and the bedroom that never cools get exactly the same air.

MyPlace IQ divides the home into up to 10 independent zones, each with its own temperature sensor. The kids' rooms at one setting, the master at another, the guest room off entirely. Set from a wall tablet or your phone, on a schedule, from anywhere.

Six zones, six settings. Two supply trunks run from the indoor unit to the Exact Air Regulators, then branch to a grille in every room — with two returns back to a single return air grille.

Advantage Air's independent testing shows MyPlace IQ zoning can cut ducted running costs by up to 46% — because you're only conditioning the rooms you're actually using.

How we work

What we won't do.
And what we will.

What we won't do

  • Quote you over the phone before measuring the home
  • Send someone with a phone to take photos and call it an inspection
  • Subcontract your install to whoever's free that week
  • Quote one number and bill a bigger one on the day

What we will

  • Measure every room, ceiling height, insulation and orientation
  • Recommend the system that fits the house, not the highest-margin job
  • Put it in writing within 24 hours, and honour it on install day
  • Send our own team — the same names that show up on every job

Why now

Five reasons to sort it out before December.

01

The lounge is arctic. The bedrooms are still 28°C.

The system runs flat out for the living area because that's where the thermostat is. Down the hall, nothing changes. You close the lounge vents to push air to the bedrooms and now the lounge is warm too.

02

You cool six rooms so you can sleep in one.

Four of them are empty all day. The system doesn't know that, so it conditions them anyway — and you pay for every one.

03

The west-facing room is unusable from 3pm.

Afternoon sun through a single aspect. It's the room that needs the most work and it gets exactly the same air as the hallway.

04

The old unit is on its last summer.

Twelve-year-old ducted system. Fan motor on borrowed time, refrigerant down, working harder every year to do less. Replace it now and you set the price. Wait for the breakdown in January and the breakdown sets the price.

05

In December, everyone's three weeks out.

The first 35°C day fills every diary on the Gold Coast. Book in September and you choose the install date. Book in December and you take what's left.
