One system for summer and winter
A Fujitsu reverse cycle system cools the house through a Perth summer and warms it when winter comes around. Our servicing keeps it doing both, season after season.
Each Fujitsu system has its own features and settings, and they only pay off when the system is set up and maintained the right way. We work on Fujitsu ducted air conditioning, split systems and VRF, and service each one to run as efficiently as it should.

Keeping your Fujitsu in good shape
A well-serviced Fujitsu costs less to run and keeps going for longer. These are the three things we bring to every job we do.

Affordable
Fair prices, set out clearly. You see what the job costs up front, so there are no surprises on the bill.
Upfront quote before any workProfessional
The people working on your Fujitsu are certified and experienced, and they set a high bar for their own work.
Fully ARC licensed techniciansHigh quality
Genuine Fujitsu parts go into every repair, fitted with up-to-date methods so the system works as it should.
Genuine Fujitsu partsFujitsu faults we see and fix
Ducted systems are a particular focus for us, though we work on every kind of Fujitsu in Perth. We trace each fault to its root cause and repair it properly.
Send us the code or the light pattern, or just describe the symptoms.
A Fujitsu tells you something is wrong by flashing a pattern on the indoor unit's indicator lights. That pattern narrows things down. On site, we test the full system with proper diagnostic equipment to pin down the fault, then quote the repair before any work begins.
Book a diagnosisFaulty PCBs
A power surge, or just years of service, can knock out the main control board. We find and replace failed Fujitsu PCBs, capacitors and relays.
Compressor faults
No compressor, no cooling. When a Fujitsu compressor won't start or won't cool, we test it and repair or replace it.
Gas & refrigerant leaks
If your Fujitsu is short of gas, cooling drops off and power bills climb. We leak-test, repair the leak and re-gas it correctly.
Fan & blower motors
A ducted blower or outdoor fan motor that rattles, stalls or quits needs attention early. We repair or replace it with quality parts.
Communication errors
Signal faults between the indoor and outdoor units are a common Fujitsu problem. We trace where the signal drops out and fix it at the source.
System overloads & electrical
An overload or electrical fault can trip your Fujitsu or shut it down altogether. We find the cause and fix it safely.
Thermostat & controller faults
Controller unresponsive, screen blank, or settings resetting themselves? We diagnose and repair the controls that run your Fujitsu.
Error codes & no cooling
Fujitsu indicator lights flashing, or the system has stopped cooling? We decode the flashes and find what's causing it.
Need an insurance report?
When a storm, a power surge or other insurable damage stops your Fujitsu, we'll come out to inspect it and run a diagnostic across the full system. You get a detailed fault report and a repair quote for your insurance company, which makes the claim much easier to put together.
Fujitsu experience that cuts downtime
Fujitsu systems are familiar ground for us. That means less time spent working out what's wrong, less downtime for you, and a comfortable home or workplace again sooner.
What Oasis Air Conditioning brings to your Fujitsu
Across Perth, from Subiaco and Wembley out to Ellenbrook, people rely on Fujitsu for dependable, energy-efficient air conditioning. We specialise in the brand and know how its systems are put together, right down to the control boards and wiring, and we cover service and maintenance as well as installation.

Inside a Fujitsu service visit
Servicing your Fujitsu regularly keeps it efficient and helps it last. On each visit, our Perth technicians take care of jobs like these:
- Filter & return-air inspection
Filters are inspected, then cleaned or replaced, which keeps airflow up and the air in your home healthier.
- Refrigerant level checks
Refrigerant levels are checked so your Fujitsu cools as it should, without working harder than it needs to.
- Full system performance check
The whole system is put through its paces so we can spot wear early and head off future breakdowns.
What Perth owners ask about Fujitsu service
Plain answers to the Fujitsu questions we hear most from Perth owners, including how often to service and what a communication error actually means.
How often should a Fujitsu air conditioner be serviced in Perth?
We recommend a full service at least once a year, ideally in spring before the heat arrives. A Fujitsu system that runs most days, a ducted system in a larger home, or any system in a commercial space does better with a service every six months.
Perth dust and sea air build up on coils and filters quickly. A yearly clean and check keeps running costs down and catches small faults before they turn into a breakdown in the middle of summer.
My Fujitsu is showing a fault code. What should I do?
Fujitsu systems flash the code through the indoor unit's indicator lights, so note the pattern (or any code on the controller), then switch the system off at the controller and send us the code with your booking. It narrows the fault to one part of the system, and our technicians test the full system on site to pinpoint it before quoting.
Please don't keep restarting a system that trips repeatedly. That can turn a small fault into a compressor failure, which is a far bigger repair.
Do you use genuine Fujitsu parts?
Yes. Every repair uses genuine Fujitsu parts, which match your system and the manufacturer's specifications and keep any remaining warranty intact. If a part needs ordering, we tell you how long it should take when we quote.
Will having Oasis service my Fujitsu affect the manufacturer's warranty?
Manufacturers' warranty terms usually ask for regular servicing by a licensed technician using genuine parts, and that is exactly how we work. Our technicians are fully ARC licensed, we fit genuine Fujitsu parts and we record every service, so you keep the service history warranties ask for. If you're unsure what your warranty requires, send us the terms with your booking and we'll check before we start.
What does a Fujitsu service call cost?
Your service price is agreed when you book, before anyone visits, with no hidden fees. If the technician finds a fault that needs parts or more work, you get a clear quote before any of it begins. To get a price quickly, fill in the booking form with your system type and what it is doing.
Which Fujitsu systems do you service?
All of them. We service and repair Fujitsu wall splits, ducted reverse cycle systems, cassettes and the Airstage VRF range used in commercial buildings, across Perth from Ocean Reef in the north to Mosman Park in the south, and inland to Ellenbrook and The Vines.
Why does my Fujitsu show a communication error?
A communication error means the indoor and outdoor units have stopped talking to each other. The usual causes are a damaged interconnecting cable, a failing control board or a loose connection after storm or rodent damage. Book a diagnosis and we'll test the wiring and both boards rather than guessing at parts.
