Why Perth Homes Choose Ducted Air Conditioning
Perth summers regularly push past 40°C, and our winters can drop to single digits overnight. A whole-home system handles both. It cools every room through a network of ceiling vents and switches to heating mode when the temperature drops, all from one outdoor unit and a wall controller.
Unlike a split system that covers one room at a time, a ducted setup covers your entire house. The indoor unit sits in the roof space, connected to insulated ductwork that delivers conditioned air to each room through ceiling outlets. Only the vents and controller are visible inside.
For Perth families who want consistent comfort in every room without a wall-mounted unit on every wall, it’s the practical, aesthetically pleasing choice.
How a Ducted System Works
There are three main parts: an outdoor unit (“compressor”), an indoor unit (“fan coil”), which is usually in your ceiling cavity, and insulated ducts running through the roof to each room.
The outdoor unit draws in air and either cools or heats it using a refrigerant cycle to the indoor unit, where a fan blows over the coil, conditioning the air. That conditioned air gets pushed through the ductwork and out through vents in each room. A return air grille pulls the room air back into the system for reconditioning. And the cycle continues until the set point temperature is met.
The Daikin, Panasonic & Hisense systems we install are all reverse cycle, so they cool in summer and heat in winter using the same unit. That makes them more energy-efficient than running separate heaters and coolers. For the full range, see our Daikin ducted systems page.
Zoning — Cool or Heat Only the Rooms You’re Using
One of the biggest advantages of a modern system is zoning. You divide your home into zones (say, bedrooms in one and living areas in another) and set different temperatures for each.
Heading out for the day? Turn off the bedrooms and keep the living room comfortable. Kids like it cooler at night? Drop their zone a couple of degrees below yours.
We install Advantage Air MyAir5 and MyPlaceIQ zone controllers, which let you manage up to 10 individual zones from a touchscreen panel or the mobile app. You only pay for the rooms you’re actually using, which keeps running costs down. And with the mobile app, you can control it from anywhere (warm up the house before you get out of bed on a winter’s morning or switch the cooling on so when you get home from work, it is the perfect cool temperature on a scorching 40-degree summer’s day.
Ducted Air Conditioning Installation in Perth
Every home is different, so every job starts with a site visit. Our team inspects your roof space, measures the floor plan, and works out the right system size for your property.
For a typical 4-bedroom Perth home (200–250m²), installation takes 1 day. That covers mounting the outdoor unit, fitting the indoor unit in the ceiling cavity, running insulated ductwork to each room, and connecting the controller.
We’ve been fitting systems across Perth since 1986. Over those 40 years, we’ve worked in suburbs from Ellenbrook to Joondalup, down to Rockingham. We know Perth housing: double-brick 1980s builds in Dianella, new lightweight builds in Baldivis, two-storey places in Canning Vale. We’ve done them all.
If you’re replacing an older unit, our system replacement service makes the process straightforward. We remove the old unit and install the new system with minimal disruption (if needed, we can upgrade the ductwork as well, but typically this isn’t needed).
Our Brands: Daikin, Panasonic & Hisense
We’ve held Daikin Super Dealer status for over 17 years. That’s not a title you pick up casually. It means meeting Daikin’s highest benchmarks for installation quality, volume, and customer service every year.
We also install Panasonic systems, which offer strong performance at a slightly different price point.
Finally, for an entry-level offering, we have Hisense.
All three brands are built for Australian conditions. Daikin units keep going in temperatures up to 46°C (Perth has hit that more than once…) and heat effectively down to −20°C. Panasonic & Hisense carry similar specs.
How Much Does Ducted Air Conditioning Cost in Perth?
Pricing depends on your home’s size, the number of zones you want, the brand, and how much existing ductwork (if any) can be reused.
Here’s a rough guide for Perth homes:
| Home Size | System Size | Typical Price Range |
| 2–3 bed (up to 150m²) | 10–12kW | $8,000 – $12,000 |
| 4 bed (150–250m²) | 12–16kW | $12,000 – $16,000 |
| 5+ bed / large (250m²+) | 16–20kW+ | $16,000 – $22,000+ |
These prices cover supply, full installation, and commissioning. Extras like additional zones, premium controllers, or tricky roof configurations add to the cost.

Keeping Your System Running
A ducted air conditioning system is a serious investment, so looking after it matters. We recommend a professional service at least once a year to check refrigerant levels, clean filters and coils, inspect ductwork for leaks, and make sure everything is running at peak efficiency.
Regular servicing extends the life of your unit, keeps energy bills in check, and catches small problems before they become expensive ones. They are needed from year 1 because you are responsible for maintaining your unit, which is part of catching any issues during the warranty period.
Our service team handles warranty work on most major brands, not just the ones we sell. Book a service through our air conditioning servicing page.
Common Questions About Ducted Air Conditioning in Perth
How long does installation take?
For most Perth homes, 1 full day. Larger homes or complex rooflines may need an extra day. We’ll confirm the timeline at your site inspection. With replacement systems without ductwork, often half a day is all that is needed.
Is a ducted system more expensive to run than split systems?
Not necessarily. With zoning, you only cool or heat the rooms you’re using. If you’d otherwise need 4 or 5 splits to cover the same area, a single zoned system often costs less to run.
Can you fit a system into an existing home?
Yes. We’ve retrofitted systems into homes of all ages across Perth, including older double-brick builds. The main requirement is enough ceiling space for the indoor unit and ductwork. Our team checks this during the site visit.
What size system do I need?
It depends on floor area, insulation, window sizes, and orientation. Undersized systems run constantly without reaching temperature. Oversized systems cycle on and off too frequently. We size every system using a proper heat load calculation, not a rough guess.
How long do these systems last?
Two major factors influence how long a system lasts;
(1) High-quality installation, without cutting corners.
(2) Regular maintenance of the system, year on year.
Our 40 years of experience have shown that a great brand system, installed poorly, can fail in 6 years, and a unit installed well but never maintained can require a $2500 repair that could have been prevented with a regular maintenance program.
With good installation and regular maintenance, you should expect on average about 12-15 years (often times more!). Surprisingly, it isn’t all about the brand of the unit.
