Key Features & Benefits

Built-in Wi-Fi & Voice Control

The T Series includes built-in Wi-Fi, allowing you to control temperature, timers, and operating modes remotely through the AC Freedom App. It is also compatible with Google Home and Amazon Alexa for convenient voice control.

Strong Energy Efficiency

The 3.5kW model delivers up to a 5.5-star cooling efficiency rating in hot climates, helping reduce running costs while maintaining consistent comfort. Inverter technology continuously adjusts compressor speed to improve efficiency and reduce power usage.

Long Distance Airflow

The HSNRT35B can deliver airflow up to 10 metres, helping conditioned air reach further across the room and reducing hot and cold spots. The indoor unit also features 3D airflow, with blades that swing horizontally and vertically for more even temperature distribution.

Quiet Operation

Designed for bedrooms and study areas, the unit operates quietly while still delivering strong heating and cooling performance. Sleep Mode further improves overnight comfort by reducing noise and adjusting operation automatically.

High-Density Air Filter

A high-density air filter helps capture dust, airborne particles, and impurities to create a cleaner indoor environment. The unit also includes a self-cleaning cycle to reduce moisture build-up and help prevent mould, bacteria, and dust inside the system.

Boost / Turbo Mode

Boost mode quickly cools or heats the room by running the system at maximum performance until the desired temperature is reached. This makes it ideal for very hot summer days or cold winter mornings.

Designed for Australian Conditions

The outdoor unit is designed to operate in harsh Australian climates, with an operating range from -15°C to 52°C outdoor temperature. DRED capability is also included for compatibility with energy demand response programs.

Eco-Friendly R32 Refrigerant

The system uses modern R32 refrigerant, which improves energy efficiency and has a lower environmental impact than older refrigerants.

Compact Design

The indoor unit measures approximately 316mm high, 940mm wide, and 224mm deep, making it suitable for bedrooms, home offices, and compact wall spaces.

7-Year Residential Warranty
