All You Need To Know About Ducted Zoning For Your Air Conditioning

In recent years, ducted zoning has become an increasingly popular option for air conditioning systems in Christchurch New Zealand. This is because this type of heating and air conditioning provides more control and flexibility over the home environment. 

This article will explore the benefits of ducted zoning for air conditioning in Christchurch, as well as the installation process for this system.

What is Ducted Zoning?

Ducted zoning is an energy efficient type of heating and cooling system for homes with more than one heating and cooling zone. It is a dedicated system of ductwork and air conditioning units that are set up to heat or cool each room or area of a house independently. 

This is distinct from split system air conditioning which uses an outdoor condensing unit connected to multiple indoor air handling units. The advantage of ducted systems is that they can provide greater control over the climate of different parts of a building or home. 

Benefits of a Ducted Zoning System

There are several benefits of installing a ducted zoning system in Christchurch, especially if you live in an area known for its cooler winters and warmer summers. 

The system can be set up to heat or cool certain parts of the house independently. This means that less energy is wasted as different rooms can be at different temperatures depending on what is most comfortable for that specific area. 

Secondly, using a single unit for multiple areas of the home is more efficient than using separate units for each room. This means that more energy will be saved, as well as improved air quality, since air is not recirculated from room to room. 

Thirdly, installing a ducted system keeps the home more aesthetically pleasing since the air conditioning units are located in the attic or false ceiling. 

Installation Process for Ducted Zoning Systems

Installation of a ducted zoning system begins with a detailed assessment of the home, including the number of rooms and the square footage. The assessment will also take into account any existing ductwork. 

A certified HVAC technician will then discuss the cost and timeline for the project, including a price quote for the installation, maintenance, and any other services that may be necessary.  

Once the assessment and quote have been completed, the HVAC contractor will design the air conditioning system. This will involve deciding how many zones the system needs, and where each zone will be. This design phase usually includes drawings of the plenum, which is the distributor through which the cool and warm air will move in the home. 

The final step in the installation process is the actual installation of the system. This typically involves a three-man team that will install the ductwork, the supply and return grilles, and the thermostats and controllers. 

Once the system has been set up, the technician will then connect the necessary electrical wiring and switch the system on so it can start providing hot and cold air. 


Ducted zoning is an energy efficient way of controlling the temperature of different parts of a home or building in Christchurch, New Zealand. The advantages of this system include energy savings, improved air quality, and improved interior aesthetics. 

Installing a ducted zoning system involves an assessment and design phase, followed by the actual installation. When done correctly, a ducted zoning system could save homeowners money on their energy bills and make their home environment more comfortable.
