What is Zoning for my ducted heating or air conditioner?

What is Zoning?

You can think of Zoning as little doors installed in your ductwork.

These doors can open and close certain ducts, giving you the ability to control which rooms are air-conditioned.

Why is Zoning Beneficial?

Save on Running Costs

Zoning saves on running costs, as you only heat or cool rooms you are currently using.

Why spend money air-conditioning spare or unoccupied rooms? Do you have a guest room that isn’t being used? Simply don’t heat or cool that room.

When a zone is selected, heating or cooling won’t be delivered to the rooms outside of that zone.

A home that has two zones can save significantly on running costs by simply switching off one zone.

Day and Night Comfort

During the day, keep your living areas at perfect temperature and turn off the areas you are not using, such as bedrooms.

Of a night time, turn off the living areas and heat or cool only the bedrooms.

Works with individual house design

Do some of your rooms face North? Do you have skylights? Or a Double Story home?

These areas may be naturally warmer on a sunny day. You can save on running costs by turning the heating down or off in these areas on sunny days.

Personalised Climate with Temperature Control

Does each member of your family have different needs when it comes to temperature?

Adding Temperature Sensors allows you to program different temperatures for different zones and is the perfect way for you to create a personalised heating and cooling experience for you and your family.


You can either use zoning on manual mode as needed, or auto mode.

Auto-mode allows you to set a weekly program for your house’s heating and cooling.

You can program what days and times you would like what temperature and zones to be running.

So you never have to come home to a hot or cold house again!

Can I Add Zoning to my Current System?

Zoning is best when installing it with a new unit so you can design your ductwork to suit how you want your zones.

However, most existing Gas Ducted Heaters and Ducted Reverse Cycle Systems are compatible with zoning.

How many zones you can add and what rooms can be zoned together will depend on your house and duct layout.

2 Zones (1 for the bedrooms, 1 for the living areas) are the most common option, but you can have more depending on what suits your lifestyle.

For example, if you worked from home, you could have a 3rd zone for your home office so you aren’t air-conditioning your whole house during the day.
