Woke up to find our ducted heater wasn't working with an error code on the Netcontroller. Turning the heater off and on again didn't resolve the issue so I reached out for recommendations on Facebook. Someone recommended CoreTemp - they'd had a fault with their heater and CoreTemp fixed it straight away. Rang CoreTemp and Alice was extremely helpful, said she had a Technician nearby and would see if he could swing by. Gave her the details of the issue and less than 10 minutes later Alice rang back to say Nathan was on the way. Nathan was very careful and considerate, gave the unit a service, including cleaning the flame sensors, did a reset on the circuit board and then a reset on the Netcontroller panel and the fault cleared and the heater was operational again. All done by midmorning. Excellent report sent through detailing the work done including photos. Highly recommend CoreTemp for their service and professionalism.Posted on Google

This is the second split system bought and installed by CoreTempAustralia. This time my Mum needed to replace a system that had packed up in her home, I rang on Monday morning around 10am and within 15 minutes Emily was at her place. Emily was very informative on which size system was needed for Mum's house and talked Mum through the process. CoreTempAustralia installed the unit on the Friday of the same week and the workmen did a great job, cleaned up after themselves. So my 84 year old Mum was greatly appreciative on the ease of the whole process. Highly recommend CoreTempAustralia.Posted on Google

We replaced our gas heater with a split system and had a great experience from start to finish. The team was professional, friendly, on time, and communication was excellent throughout the process. I had a couple of questions after the installation and really appreciated the prompt and friendly response, including the team coming back twice without hesitation to make sure it’s all done properly. Very happy with the service and would definitely recommend.

Gas ducted heating uses a central heater, usually installed in the roof space, to warm air and distribute it through ducts into each room. You control the temperature through a wall thermostat and the system maintains steady warmth throughout your home.
The cost depends on your home’s size, the system capacity required and the complexity of the ducting layout. Every property is different, which is why we carry out an onsite assessment and provide a clear, detailed quote before any work begins.
In most cases, yes. If there is suitable roof or subfloor space for ducting, we can install a new system in an existing home or replace an older unit. We’ll assess your property and confirm what’s practical during the quote process.
Modern systems are significantly more efficient than older models. When correctly sized and maintained, ducted gas heating provides effective whole-home warmth without excessive energy use. Zoning can also help you manage running costs.
We recommend servicing your system at least once every 12 months. Regular maintenance helps ensure safe operation, keeps the system running smoothly and reduces the risk of breakdowns during winter.
When replacing an existing system, we remove the old heater and install the new unit, checking the condition of your ductwork and controls at the same time. If upgrades are needed to ensure proper performance, we’ll explain your options clearly before proceeding.
