QUICK ANSWER
What is Rinnai ducted air conditioning?
It is a whole-home reverse cycle system. One indoor unit sits out of sight in the roof space and sends heated or cooled air through insulated ducts to discreet ceiling outlets in each room. Zoning lets you condition the whole house or only selected areas, without a wall-mounted unit in every room.

WHY RINNAI DUCTED
Whole-home comfort that stays out of sight.
Everything Perth homeowners ask for in one system: year-round comfort, quiet operation, lower running costs and a clean ceiling.
Heating and cooling in one system
Reverse cycle comfort keeps you cool through Perth summers and warm on winter mornings, from a single system you control in one place.
DC inverter efficiency
A Direct Current inverter compressor adjusts output precisely. Rinnai rates a typical output of around 3kW of heating or cooling for every 1kW of electricity used.
Quiet and out of sight
The indoor unit sits in the roof space, leaving only slimline ceiling diffusers. Indoor noise starts from 28 dB(A) on selected models.
Dehumidification mode
Manages humidity on sticky summer days, so rooms feel comfortable without over-cooling.
Automatic restart
If the power drops out, the system restores operation automatically, so you come home to the comfort you set.
Splittable for tight roof spaces
The 15kW, 18kW, 20kW and 24kW indoor units can be carried into the roof in sections, which makes many retrofits simpler.

WHY DUCTED SUITS PERTH
Built for hot afternoons and cool winter mornings.
Perth homes face long summers, strong westerly sun on large glass areas and surprisingly cold winter nights. A correctly zoned Rinnai ducted system cools living areas in the afternoon, switches to bedrooms at night and heats the whole home in winter. Read why reverse cycle air conditioners suit Perth’s climate.
- Rated to operate up to +50°C outdoors
- Automatic restart after power outages
- Dehumidification for muggy days
- Suits new builds and existing homes
AN HONEST VIEW
Is ducted air conditioning right for you?
Ducted is the premium choice for whole-home comfort, but it is not for every home. Here is what to weigh up.
- Heats and cools the whole home from a single system
- Delivers consistent temperatures from room to room
- Discreet ceiling outlets instead of wall-mounted units
- Zoning conditions different areas independently
- Quiet, with most equipment out of sight
- Can improve energy efficiency when zoning is used well
- Higher upfront cost than a split system
- Needs sufficient roof or ceiling space for ductwork
- Professional design and installation are essential
- Running costs depend on home size, insulation and usage
- Regular maintenance keeps performance and efficiency up
- Retrofits can involve additional installation work
HOW WE SIZE YOUR SYSTEM
Designed around your home, not the number on the box.
Correct sizing is the single biggest factor in how a ducted system performs. This is how we get it right.
1
Site assessment
We look at your floor plan, roof space, orientation, glazing and how each room is used.
2
Heat load calculation
We calculate what each area needs, so the system is sized to your home rather than guessed.
3
Duct and zone design
Outlet positions, duct runs, zones and controller placement are planned around your routine.
4
Installation and handover
ARC Tick licensed technicians install and commission the system, then show you the controller and app.

DUCTED INSTALLATION ACROSS PERTH
Ducted reverse cycle air conditioning installation in Perth.
We supply and install Rinnai ducted reverse cycle air conditioning across the Perth metropolitan area, including the northern, southern, eastern and western suburbs and the Perth Hills. Every system is sized from a heat load calculation and installed by ARC Tick licensed technicians, whether you are building new, renovating or replacing an existing ducted system.
What ducted air conditioning costs in Perth
The installed cost depends on the system capacity, your home’s layout, roof access, electrical requirements and the number of zones and outlets. A home-specific written quote is more reliable than comparing unit-only prices online, so your free quote shows the recommended Rinnai system and exactly what is included.
Replacing an old ducted system
If your current system struggles on hot days, heats and cools rooms unevenly, runs noisily or keeps needing repairs, it is worth comparing repair against replacement. We assess the existing unit, ductwork, electrical supply, controls and access, then confirm what can be retained and what should be upgraded. Removal of the old system can be included in your quote.
New builds and renovations
Planning ducted air conditioning early gives the best outlet positions, duct runs and zone layout. Start with our new home air conditioning guide, and if you are still deciding between systems, read our split system vs ducted guide.
DUCTED FAQs
Rinnai ducted questions, answered.
The questions Perth homeowners ask most before choosing ducted air conditioning.
What size Rinnai ducted system do I need?
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.
Can Rinnai ducted air conditioning heat as well as cool?
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.
Can ducted air conditioning be installed in an existing home?
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. Building new? See our new home build air conditioning checklist.
How many zones can a Rinnai ducted system have?
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.
How long does a ducted air conditioning system last?
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.
Is ducted air conditioning more expensive than split systems?
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. Compare the two in our split system vs ducted guide.
How much does ducted air conditioning cost in Perth?
The installed cost depends on the system capacity, home layout, roof access, electrical requirements and the number of zones and outlets. Because every home is different, we provide a free written quote showing the recommended Rinnai ducted system and what is included, rather than a generic online price.
Do you install ducted air conditioning across Perth?
Yes. We install Rinnai ducted reverse cycle air conditioning across the Perth metropolitan area, including the northern, southern, eastern and western suburbs and the Perth Hills. Enter your suburb or postcode in the quote form and we will confirm availability.
