Reverse-cycle heating and cooling for your whole home

Brands we install
Walk into a cool, quiet home on a hot summer day, or a warm one on a cold winter night. That is what refrigerated reverse-cycle air conditioning does for every room at once.
The indoor unit sits out of sight in the roof space, with an outdoor unit beside the house. Air travels through ducts to vents in each room, so there are no units on your walls.
A whole-home system costs more to install than smaller systems, but zoning and solar panels help keep running costs down. With a VEU-approved model, you can also get a discount on the upfront cost.

A whole-home system uses more power than a single room unit. If you have solar panels, you can run it during the day on the power you make yourself, which brings your bills down.

One system heats your home in winter and cools it in summer. Whatever Melbourne’s weather does, your home stays comfortable.

Zoning divides your home into areas, such as living and sleeping, that you can turn on or off. You only heat or cool the rooms you are using.
We look at your home’s layout and how you live, then plan the zones to suit.

Refrigerated reverse-cycle cooling keeps working on sticky, humid days, when evaporative cooling can struggle. It also takes moisture out of the air, so your home feels fresher.

With a Wi-Fi adapter or a compatible controller, you can run your system from your phone. Turn it on before you get home, or warm the house before you get out of bed.
Refrigerated, or reverse-cycle, air conditioning heats and cools your whole home through ducts and vents in the ceiling. It has an outdoor unit and a central indoor unit, usually in the roof space. It can sometimes go under the floor if there is room and access.
Yes. Reverse cycle means the same system heats in winter and cools in summer.
Enough roof or underfloor space for the indoor unit and ducts, a spot outside for the outdoor unit, and a suitable power supply. We check all of this before quoting.
It moves heat rather than making it. In winter it draws heat from the outside air into your home; in summer it moves heat from inside to outside.
It depends on the size of your home, the number of zones, the model and whether ducts need replacing. We give you a written quote with any VEU discount shown.
They depend on your home’s size and insulation, how many zones you run and your electricity tariff. Zoning and solar panels both help lower them.
Yes. The same ducts and vents deliver both warm and cool air.
Yes. Most whole-home systems can be zoned, and we plan the zones around how you use your home.
An inverter lets the system speed up and slow down instead of switching on and off. It holds the temperature more steadily and uses less energy.
Sometimes. We check the condition, size and layout of your ducts before recommending whether to keep or replace them.
Most systems we install have a Wi-Fi option, either built in or with an adapter.
