Evaporative to ducted conversions
Evaporative to ducted reverse cycle conversions, Perth.
Heating and cooling, windows closed, every zone under control. We take the old cooler off, repair the roof ourselves, and install a modern ducted system — one team, one quote.
Why switch
Why Perth homes are swapping evaporative for reverse cycle
Heating as well as cooling
Reverse cycle heats your whole home in winter too — many people retire a separate gas or electric heater at the same time.
Works with the windows shut
Evaporative cooling needs doors and windows open to work. Reverse cycle runs with the house closed up — better for security, dust, smoke and noise.
Cool on humid days
Evaporative struggles when Perth gets muggy. Refrigerated air keeps working whatever the humidity.
Zone and control every room
Run just the living areas by day and the bedrooms at night, with smart control from your phone.
What's involved
How an evaporative to ducted conversion works
A conversion is a complete changeover, not just a new unit on the roof. It's usually a full day, including removing the evaporative cooler and patching the roof.
- 1
Free assessment & design
We look at your roof space, existing ducts and floor plan, then design a correctly sized zoned system and give you a written quote.
- 2
Remove the old cooler
We take the evaporative unit off the roof and pull out the old ducts — they're too big to reuse for reverse cycle.
- 3
Patch the roof
Tile roofs are patched with your spare tiles (or we cap the dropper and leave it on the roof). Metal roofs get the sheets patched. No separate roofer needed.
- 4
Install new ducted reverse cycle
New insulated ductwork, outlets, return air grille, indoor unit in the roof and outdoor unit outside — sealed, tested and commissioned.

We show you how to use the zones and controller, set up your first service reminder, and leave the site clean.
Old Evap Unit to New Ducted Aircon
We swapped a dated evaporative unit for a modern, efficient ducted system.
This home got a massive comfort boost — but we didn't stop there. The old machine left a big hole in the roof, exposed to the elements, and instead of calling in another contractor we repaired it ourselves.
That means less hassle, less cost, and a clean, professional finish from start to finish. With us you get more than an aircon install — you get a one-stop shop that handles everything.
Good to know
Can I keep my evaporative ducts and outlets?
The ducts, no. Evaporative ducts are too big for a reverse cycle system, so we run new, correctly sized insulated ducting.
The outlet positions, if you prefer. Best practice is to move the outlets out towards the outside walls of the house, where they work best for reverse cycle. If you'd rather not patch the ceiling, we can install the new outlets in the same spots.
