Rinnai air conditioning questions, answered.

A split system usually suits one main room. Multi-split serves several rooms from one shared outdoor unit. Ducted is the strongest option for discreet whole-home comfort. The right choice depends on how many rooms you use, your budget and the property itself.

A Rinnai inverter split system is usually the most cost-effective choice for a single bedroom, living area or home office. It heats and cools, installs more simply than ducted and lets you control that room independently.

A Rinnai multi-split connects several indoor units to one outdoor unit. Each room can be controlled independently, and you avoid covering the outside of your home with multiple condensers.

Yes. We assess the existing unit, pipework, ductwork, electrical supply, controls and access, then confirm what can be retained and what should be upgraded before quoting.

It depends on total floor area, ceiling height, insulation, glazing, orientation and climate zone. Rinnai ducted systems range from 7kW to 24kW, and the correct capacity is confirmed with a whole-of-home heat load calculation rather than a rule of thumb. Oversized systems waste energy, while undersized systems struggle on hot Perth afternoons.

Yes. Rinnai ducted systems are reverse cycle, so one system cools in summer and heats in winter. Rinnai rates a typical output of around 3kW of heating or cooling for every 1kW of electricity used, and notes that reverse cycle ducted heating is often cheaper to run than traditional gas heating.

Usually, yes. Rinnai ducted systems suit both new builds and existing homes. Retrofits need enough roof or ceiling space for the indoor unit and ductwork. The splittable 15kW, 18kW, 20kW and 24kW indoor units can be carried into tight roof spaces in sections. We confirm access during the site assessment.

The Rinnai Home Controller manages up to 8 individual zones using a touchscreen controller and wireless room sensors. If you want more zones or wider smart-home control, a compatible iZone system can manage up to 14 zones.

With correct installation and regular maintenance, Rinnai indicates 12 to 20 years is typical. Ductwork often lasts longer than the mechanical components, which can make future replacement simpler.

The upfront cost is higher because one system serves the whole home and includes ductwork, outlets and zoning. For homes that need several rooms conditioned, ducted is often the cleaner, quieter long-term solution. Running costs depend on home size, insulation, zoning and how you use it.

Most bedrooms suit a 2.5kW to 3.5kW system. As a guide, the Rinnai TX Series 2.5kW model suits about 11-17m² and the 3.5kW model about 16-23m², based on insulated ceilings up to 2.6m. West-facing rooms and large windows may need more capacity.

Living areas typically need 5.0kW to 7.0kW, and large open-plan spaces 8.0kW or more. The TX Series 7.0kW model suits about 32-47m². Ceiling height, glazing and afternoon sun all matter, so we confirm the size on site.

Yes. Inverter split systems are among the most efficient ways to heat and cool a room because they adjust output instead of switching on and off. Compare the average climate zone on the Zoned Energy Rating Label, which includes Perth. Selected Rinnai series reach up to 9 stars.

Yes. Reverse cycle split systems move heat rather than create it, which makes them cheaper to run than many traditional electric heaters. The Rinnai TX Series is designed to heat in outdoor temperatures down to -15°C.

GoldGuard is a protective coating on the Rinnai TX Series outdoor condenser coil. It increases resistance to oxidation and corrosion compared with standard coils, which is valuable in coastal suburbs exposed to salt air. It also helps speed up defrosting in heating mode.

Yes. The TX Series has built-in Wi-Fi. Using the NetHome Plus app you can switch it on or off, set the temperature and adjust fan speed from anywhere, and it works with compatible Google Assistant and Amazon Alexa devices.

iZone is a smart control system for ducted air conditioning. Touchscreen controllers and wireless sensors measure the temperature in each zone and adjust airflow automatically. It can also expand into lighting, irrigation, power monitoring and other smart-home functions.

iZone has been part of Rinnai Australia since October 2023, and iZone controls are designed for compatible ducted air conditioning designs. Compatibility, zone numbers and controller choice are confirmed for your specific system before you commit.

In many cases, yes. iZone is designed to make ducted systems smarter, including existing installations. We check your current indoor unit, ductwork, zone dampers and Wi-Fi setup to confirm what is possible.

iZone climate control systems can manage up to 14 zones, with wireless sensors and up to 12 touchscreen controllers on supported systems. Bedrooms, living areas and studies can each hold their own temperature.

Yes. iZone works with Google Home and Amazon Alexa. Apple HomeKit and Siri control require a system with iZone’s newer open connection bridge, so we confirm this before purchase.

iZone sends heating and cooling only where and when it is needed, and features such as fan auto control and occupancy sensing reduce waste. Actual savings depend on your home, insulation and how you use the system.

Yes. Rinnai designs its air conditioning for Australian conditions. Rinnai ducted systems are built to operate from -20°C to +50°C outdoors, and split systems carry Zoned Energy Rating Labels showing performance in the average climate zone, which includes Perth.

Yes. Rinnai Australia acquired iZone, a Western Australian developer of smart home and ducted air conditioning controls, in October 2023.

No. Perth Home Air Conditioning is an independent Perth business that specialises in supplying and installing Rinnai air conditioning. Rinnai Australia manufactures and supplies the products and administers the product warranty.

The installed cost depends on the system type, capacity, home layout, electrical requirements, access and, for ducted systems, the number of zones and outlets. A home-specific quote is more reliable than comparing unit-only prices online.

Running costs depend on correct sizing, insulation, glazing, the system’s energy rating, how many rooms you condition and your temperature settings. A correctly sized inverter system that only conditions occupied zones costs less to run.

Yes, when used well. Zoning lets a ducted system condition only the rooms you are using, so it moves less air and works less hard. Rinnai Home Controller and iZone both add zone control, with iZone offering up to 14 zones.

Rinnai recommends following the service maintenance schedule for your product and carrying out routine user maintenance such as filter cleaning. Regular care keeps the system efficient and supports long-term reliability.
