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.

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.

We recently engaged Core Temp to attended our broken down ducted Air Con. From start to finish they were nothing short of Amazing. They had a quick turn around, were very professional and polite inside our home and had our Air Con back up and running in no time. We could not recommend Core Temps servicing highly enough. Definite 5 Stars.

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.
