Hitachi airHome 400 Wall Mount R32 (Reverse Cycle)

A fully featured, smart wall-mounted heat pump with Hitachi FrostWash self-cleaning technology, Smart Eco occupancy sensing, and a 6-year warranty — all at a competitive price.

The Hitachi airHome 400 brings premium smart automation and self-cleaning technology to an accessible price point, making it one of the best-value feature-rich heat pumps available in New Zealand.

Hitachi's revolutionary FrostWash technology periodically cools the heat exchanger to -15°C, forming a thin frost layer that lifts dust, mould, and bacteria from the coil — then melts it away, flushing contaminants out through the drain. Independent testing shows this maintains significantly better airflow performance over time. Smart Eco mode detects when the room has been unoccupied for 20 minutes and automatically shifts to energy-saving operation. Specially curved fan blades reduce turbulence noise at lower speeds. The optional airCloud Go Wi-Fi adaptor unlocks full smartphone control, weekly scheduling, an energy cost estimator, and hands-free voice commands via Amazon Alexa or Google Home.
