The Rinnai 3.5kW Portable Air Conditioner sits in our mid-range value shortlist of portable air conditioners. Mid-capacity Rinnai for 20–25 m² rooms. We list it because it's a model Australian buyers consistently search for and buy in this category — and at its price point it's worth comparing before you decide.
Before you buy any portable air conditioner, size it to your room: allow roughly 1 kW of cooling capacity per 8–10 m² of floor space, and round up for western sun or high ceilings. Make sure the window venting kit suits your window type, and check the noise rating (dB) if it's going in a bedroom.
