A ducted reverse cycle system provides an integrated, all-electric approach to climate control, delivering both heating and cooling through a single, central system. With one unit supplying conditioned air throughout the property, it’s an ideal solution for achieving consistent, whole-home comfort without the need for multiple wall-mounted units.
Modern systems are designed to automatically adjust output automatically as conditions change, helping maintain stable indoor temperatures while optimising energy consumption throughout the year.
Conditioned air is delivered through a network of ceiling ducts and vents, helping maintain comfortable temperatures across multiple rooms, while reducing hot and cold spots.
Reverse cycle technology transfers heat rather than generating it directly, providing an efficient, all-in-one solution for both heating and cooling.
With the main equipment located and concealed within the roof space, only discreet ceiling vents are visible inside the home, keeping interiors uncluttered while still delivering powerful, whole-home performance.
Installing a ducted heating and cooling system requires correct sizing, careful duct design and precise system configuration. Our licensed technicians assess your property layout, insulation and airflow requirements to recommend the most suitable system for your home.
We install leading systems from trusted brands including Daikin, Rinnai, Mitsubishi and Brivis, ensuring reliable performance and professional installation built for long-term comfort.
Routine servicing helps keep your ducted system operating efficiently and reliably. Our maintenance includes inspecting system components, cleaning filters and coils, checking airflow and confirming all controls are functioning correctly.
Regular servicing helps protect system efficiency, support indoor air quality and reduce the risk of breakdowns during peak heating and cooling seasons.
CoreTemp installs ducted climate control systems for offices, retail spaces and other commercial environments across the Mornington Peninsula and Greater Melbourne.
These systems provide consistent comfort across larger areas while operating quietly and efficiently. We work closely with builders, property managers and business owners to ensure installations meet project specifications and compliance requirements.
Upgrading to a modern reverse cycle system may qualify for financial incentives through the Victorian Energy Upgrades (VEU) program, which helps reduce the cost of installing energy-efficient heating and cooling systems. Our team can guide you through the process and help determine if your upgrade may be eligible, as well as manage the rebate process where applicable.
We install and maintain systems from leading manufacturers including Daikin, Rinnai, Mitsubishi and Brivis. These brands are widely recognised for their engineering quality, energy performance and long service life. As authorised installers, we provide professional setup along with manufacturer warranty support where applicable.

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.

A ducted reverse cycle system uses a central unit connected to ceiling ductwork to deliver both heating and cooling throughout the home. Air is distributed through vents in each room, allowing consistent indoor temperatures.
A single ducted system can manage both heating and cooling across multiple rooms, reducing the need for several individual units throughout the house. Because most of the equipment is installed in the roof space, only ceiling vents are visible inside the home, helping maintain a clean interior look while still delivering reliable climate control.
The overall cost depends on the size of the home, the capacity of the system and the complexity of the installation. A site assessment allows us to provide an accurate quote tailored to the property.
Most installations are completed within one to two days, depending on roof space access, system size and the number of outlets required. Larger homes or more complex layouts may take slightly longer. Our team plans the installation carefully to minimise disruption while ensuring the system is set up correctly.
Professional servicing is generally recommended once every 12 months. Regular maintenance helps keep the system operating efficiently, supports indoor air quality and reduces the risk of unexpected breakdowns during periods of heavy use.
