Overall Rating Snapshot

Undelivered
Never received this product, still waiting for it. Ordered this product in November 2025. Followed up in store who said they would follow up. Received 3 emails over the next 5 months thanking me for my patience and advising there were delays in supply. Received another invoice in June confirming the purchase was paid. Still haven’t received anything. Poor service I would say. Would like my money back

Its strengths are quiet operation, Wi-Fi control and strong cooling energy ratings. The main limitation is that it is cooling-only, so it will not suit buyers wanting year-round heating and cooling from one unit.

Things to consider
This model is cooling-only and non-inverter, so it is less versatile than premium reverse-cycle systems that provide both heating and more advanced efficiency control.
Room size suitability
Up to 17m2; best suited to bedrooms, studies and other compact rooms
Energy efficiency score
8.5/10 - strong cooling-only energy ratings with 7 stars in average climates, 9 stars in hot climates and 7.5 stars in cold climates
Noise level vs category average
8/10 - indoor operation down to 22dBA is notably quiet for a small split system
Smart home integration score
8/10 - Wi-Fi enabled with Google Home and Amazon Alexa compatibility for convenient remote and voice control
Allergy friendliness
6.5/10 - the high-density air filter helps with basic air cleanliness, but it does not list advanced purification features

Q: Does cooling only mean it cannot heat in winter?
A: Yes. This is a cooling-only split system, so it does not provide reverse-cycle heating for winter use. If you want one unit to handle both seasons, this model will not cover that need on its own.
Q: Will it cool a larger lounge room or open-plan area?
A: No. Its 2.6kW cooling capacity is intended for rooms up to 17m2, so a larger lounge or open-plan space is likely to be beyond its sweet spot. In a bigger area, cooling may be uneven and the unit may need to run harder.
Q: Is this air conditioner suitable for a bedroom or study?
A: Yes. Rinnai HSNCJ26B1 is sized for rooms up to 17m2, which suits most bedrooms, studies and other compact spaces. It is less suitable for larger living areas, where cooling can feel slower and less even across the room.
Q: Can I control this Rinnai air conditioner with my phone?
A: Yes. Rinnai HSNCJ26B1 has Wi-Fi, so you can control settings remotely from a compatible app and use voice control through Google Home or Amazon Alexa. You will need home internet and the initial setup completed first.
Q: How quiet is the indoor unit at night?
A: Rinnai HSNCJ26B1 runs as low as 22dBA indoors on its quieter settings, which suits bedrooms and study spaces. Indoor noise rises with stronger airflow, so Turbo or higher fan speeds will be more noticeable when fast cooling matters most.
Q: Do I need a professional to install or relocate it?
A: Yes. This product contains no user-serviceable parts, and installation or relocation should be handled by authorised service personnel. Improper handling can cause leakage, electric shock or fire, so it is not a DIY install.
