Energy Efficient Inverter Technology
Conventional air conditioners run at a fixed speed, providing a set amount of cooling and heating. They use a 'stop and start' principle to maintain a desired temperature.
In contrast, an inverter system utilises advanced technology to automatically adjust its power input. This allows for minimum energy consumption while ensuring optimal comfort levels.
It functions like a car's accelerator, gradually increasing or decreasing power as needed. It intelligently adjusts itself based on the required heating or cooling. By precisely matching its output to your desired comfort level, it ensures that only the necessary amount of energy is used, avoiding power wastage.
- It reaches the desired temperature more quickly and maintains it without significant fluctuations. This results in uninterrupted comfort and energy savings of up to 70%.
- Toshiba Inverter outdoor units are the quietest units on the market, ensuring that your system is neighbour-friendly day or night.
The refrigerant used in an inverter is Puron® and has the following benefits:
Ecological
- Environmentally friendly
- Respect for the ozone layer
- Environmentally safe
- Reliable and efficient

Toshiba: Inventors of inverter technology, offering advanced solutions for lower running costs and reliability. Not all inverters are created equal.
Frequently Asked Questions
How long does a ducted air conditioning installation take?
The installation timeframe depends on the size of the property, the complexity of the system and whether it is a new build or an existing home. Most residential ducted air conditioning installations can be completed within a few days. Larger homes and commercial projects may require additional time. Before work begins, we provide clear recommendations and explain the installation process so you know what to expect.
Is ducted air conditioning energy efficient?
Modern ducted air conditioning systems are designed to deliver excellent energy efficiency when correctly sized and installed. Many systems include zoning features, allowing you to heat or cool only the areas being used rather than the entire property. This can help reduce energy consumption and improve running costs. Choosing an energy-efficient system and maintaining it regularly can provide long-term savings while keeping your property comfortable year-round.
Is ducted air conditioning suitable for my home or business?
Ducted air conditioning is an excellent option for many homes, offices and commercial premises because it provides discreet and consistent temperature control throughout the property. The suitability of a system depends on factors such as building size, layout and your heating and cooling requirements. A professional assessment can determine the best system design for your space. With the right solution, ducted air conditioning can deliver reliable comfort, improved efficiency and a clean, streamlined appearance.

What is a ducted system?
Ducted Air Conditioning is an economical way to control the Temperature & Humidity in your home or office where there are multiple rooms that all need air-conditioning.
1. Ducted Indoor Unit
An indoor fan coil unit is installed inside your ceiling space, (the average system requires a minimum ceiling space of 600mm). This distributes the air through insulated ductwork to the rooms required. The fan coil can be adjusted to control the air being circulate both for temperature and airflow.
2. Ducted Smart Zones
Zones can be added to allow areas to be shut down when not required. This gives you the flexibility to switch areas on or off as required.
For example, it is common to separate the bedrooms from the living areas, allowing you to use either one zone at any one time or both whenever required, saving you money on running costs.
3. Ducted Outdoor Unit
The outdoor unit is located externally in a suitable location and is connected via copper pipes and electrically to the indoor unit in the ceiling. We recommend Toshiba inverter ducted systems as they are quieter and more energy-efficient. Made in Japan.

4. Air Outlets
Also known as Air Vents, Grilles or Diffusers – the air outlets fitted through the ceiling in the rooms required. Insulated flexible ducting connects the fan coil unit to these air vents to transport the flow of climate-controlled air. Outlets come in many styles.
5. Return Air Vent
A Return Air Vent is centrally located to draw the air that has been circulated throughout the premise to re-condition the air to the temperature that has been selected.
6. Ducted Control Options
Thermostat Controller
Thermostat controllers vary from unit to unit, and can range from a standard temperature control operation or programmable time/ temperature settings.
Smart Zone control system with optional WiFi
The ultimate control system allows you to pre-program each individual zone to switch on and off at when required and select individual temperatures, per zone. Each zone works independently, allowing the system to control the selected temperature whenever required in each room. This ensures that everyone is comfortable all year round.
Wi-Fi option allows you to control your system from your mobile phone while you are at home or away.
