Company Background

Kaden is an Australian heating and cooling brand owned by the Reece Group, one of Australia’s largest suppliers of plumbing and air-conditioning products. While the current Kaden brand is fairly new, it is backed by Reece’s long-standing experience and nationwide service network.

Kaden makes air conditioners for homes, including split systems, ducted systems, and evaporative coolers. The KSI split-system range is its main option for bedrooms and living areas. These systems are sold through specialist air-conditioning suppliers and installed by licensed technicians, rather than being sold in regular appliance stores.

Air Conditioner Range, Efficiency & Performance

The Kaden KSI series are wall-mounted split-system air conditioners spanning from 2.0kW to 8.5kW capacities. It is a reverse-cycle system, meaning it can both heat and cool your home. The range includes sizes for small bedrooms through to larger living areas, with a focus on efficient, quiet performance for everyday use.

KSI models use inverter technology, which helps the system run smoothly and use less power, and R32 refrigerant, a newer cooling gas that is more energy-efficient and better for the environment.

Key features

• Cooling and heating in one system

• Built-in Wi-Fi and app control

• Energy-saving and sleep modes

• Anti-bacterial coating to help reduce mould and bacteria inside the unit

• Follow Me mode, which adjusts temperature based on the remote’s location

Kaden Air Conditioner Warranty (Australia)

Kaden offers a 7-year parts and labour warranty on KSI split-system air conditioners purchased from 1 January 2026, as long as the unit is installed by a licensed technician. Units purchased before this date are covered by a 5-year parts and labour warranty.

What the warranty covers

The warranty covers faults caused by faulty materials or workmanship during the warranty period. If something goes wrong, Kaden will repair or replace the affected parts. Warranty work must be carried out by an authorised Kaden service agent, and proof of purchase is required. Both the indoor and outdoor units are covered.

Key conditions

To keep the warranty valid:

• The system must be installed by a licensed technician

• Installation must follow Kaden’s guidelines

• The unit must be used for normal home heating and cooling

• Basic maintenance is required, such as cleaning filters and keeping airflow clear

Full terms are outlined in Kaden’s warranty document.

Summary

Kaden’s warranty is strong for a mid-range brand, with the 7-year coverage on newer purchases offering extra peace of mind. As with most air conditioners, correct installation and basic upkeep are required to maintain coverage.

Pros & Cons

Pros	Cons
7-year warranty applies to newer purchases from January 2026	Shorter brand history under current Kaden name
Quiet and efficient performance in smaller bedroom-sized systems	Limited independent long-term performance data available
Strong Australian support through Reece distribution and service network	App control is included, but there is no energy tracking or voice control

Final Verdict

The Kaden KSI split-system range sits in the mid-range of the Australian market and covers the most common room sizes found in homes. It includes the standard features most people expect in a modern air conditioners, along with a long warranty, depending on when the unit was purchased.

Smaller models are best suited to bedrooms and small living areas, while larger units are designed for open-plan spaces where strong airflow matters more than ultra-quiet operation. Compared with more established brands, there is less long-term performance data available, and smart features are limited to basic app control, such as turning the system on and off, setting temperatures, and using timers. 

Overall, Kaden appears to be a reasonably priced and practical option for Australian households looking for a mid-range split system.
