Servicing can be scheduled around your operating hours to minimise disruption to staff and customers, helping maintain comfortable conditions without interrupting daily operations.
Cleaning filters and internal components helps maintain proper airflow, supporting more efficient heating and cooling across commercial spaces.
Regular servicing allows sensors, thermostats and airflow levels to be checked so the system maintains stable indoor conditions during daily operation.
Scheduled commercial air conditioning maintenance helps identify developing faults early, reducing the risk of unexpected system failures that can impact staff comfort, customer experience and daily operations.
We service a wide range of commercial systems, including ducted, VRV/VRF and split configurations, with maintenance tailored to system type, usage demands and operating hours.
A routine commercial air conditioning service includes inspecting filters, cleaning internal coils, reviewing refrigerant pressures and assessing condenser units to help maintain reliable system performance.
If a system is losing cooling capacity, making unusual noises or displaying faults, our technicians can diagnose the cause. Repairs may involve electrical components, airflow restrictions or refrigerant-related issues.
If a system is struggling to maintain consistent temperatures, upgrading key components or controls can help improve performance and efficiency.
We offer tailored maintenance programs based on your system type, usage and operating hours. Regular servicing is planned in advance to ensure consistent system performance, reduce the risk of breakdowns and support long-term equipment reliability.
Our technicians service commercial air conditioning equipment from well-known manufacturers including Daikin, Mitsubishi Electric, Hitachi and other widely installed HVAC brands. Servicing procedures follow manufacturer guidelines to help protect warranties and ensure equipment continues operating as intended.

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.

Commercial air conditioning systems are typically serviced every 6 to 12 months depending on usage and building size. Regular commercial air conditioning servicing helps maintain airflow, cooling capacity and overall system performance.
A commercial air conditioning service generally includes cleaning filters, inspecting internal coils, checking refrigerant levels, reviewing electrical components and testing indoor and outdoor units.
Cooling performance may reduce if airflow is restricted, filters are blocked or refrigerant levels are low. Servicing allows technicians to identify the cause and restore normal operation.
Servicing costs vary depending on system size, accessibility and whether repairs are required. After inspecting the system, technicians can provide clear pricing before beginning any work.
Servicing time depends on the size and complexity of the system. Our technicians plan each visit carefully and can schedule work around business hours where possible to restore comfortable indoor conditions with minimal disruption.
