Melbourne’s climate has a way of keeping you on your toes. One morning you’re rugging up for a cold southerly and by Thursday afternoon you’re sweltering through a forty degree scorcher, sometimes all in the same week. That unpredictability is exactly why more Melbourne homeowners are turning to reverse cycle ducted heating and cooling as their go to whole home comfort solution and why getting the installation right from the start matters so much.
At Gaschill, we’ve been helping Melbourne households make the switch to smarter, more efficient climate control for years and ducted reverse cycle systems sit at the heart of what we do best.
A reverse cycle ducted system is a single, unified setup that handles both heating and cooling through one outdoor unit and one indoor unit, with a network of ducts and ceiling vents distributing conditioned air throughout your home. In winter it extracts heat from the outside air and pumps it indoors. In summer it reverses that process, pulling heat out of your home and releasing it outside. The result is efficient, even temperature control across every room without the clutter of multiple wall units or the dry, recycled air you sometimes get from older gas systems.
The “reverse cycle” part of the name simply refers to this ability to run in both directions and it’s what makes these systems so much more cost effective to run than straight electric heating. Rather than generating heat from scratch, they’re moving it, which means for every unit of electricity consumed, you can get three to four or even five units of heating or cooling in return. For a Melbourne home that needs reliable performance across both seasons, that efficiency adds up quickly on your energy bills.
The combination of Melbourne’s genuine seasonal range and the shift away from gas appliances makes ducted reverse cycle heating and cooling an especially sensible choice right now. Many households that once relied on a ducted gas heater in winter and a split system or evaporative cooler in summer are finding that a single, well designed reverse cycle ducted system can handle both jobs more efficiently and with less maintenance overhead.
There’s also the practical matter of aesthetics. A ducted system keeps all the hardware out of sight. The indoor unit typically sits in the roof cavity, the outdoor unit is tucked away at ground level and all you see inside your home are slim, discreet ceiling vents. For period homes in suburbs like Hawthorn, Brighton or Camberwell where preserving the character of the interior matters, this hidden installation approach is a major drawcard compared to wall-mounted units that interrupt architraves and plasterwork.
And then there’s the question of coverage. A properly designed ducted system with smart zoning can condition every room in the house simultaneously or independently, which a collection of split systems simply cannot match without significant extra cost and multiple controller interfaces to manage.

When compared to other systems, Dominator Series™ is the most powerful single phase reverse cycle ducted system on the market for heating performance. Under rated conditions, it delivers 20kW of heating with just 5.065kW of power input, achieving nearly 400% energy efficiency, and can reach a maximum heating output of 24.75kW.
Zoning is one of those features that sounds straightforward until you realise how much it changes day to day life with a ducted system. The basic idea is that your home is divided into separate zones, typically corresponding to bedrooms, living areas and other spaces and you can choose which zones are active at any given time. Heating the whole house when everyone is gathered in the kitchen and lounge on a winter evening makes sense. Heating the bedrooms during the day when nobody is in them does not and a good zone setup means you simply don’t have to.
The Braemar Dominator Series that Gaschill installs comes standard with four radio frequency sensors and can be expanded to accommodate up to eight zones, with individual temperature control for each one. The wired wall controller gives you a clear overview of what’s happening across the whole system and you can set temperature schedules, so the house is warming up before you get out of bed in the morning without having run all night. An optional Wi-Fi module also allows you to manage everything remotely, which is genuinely handy when Melbourne decides to throw an unexpected warm snap at you mid-afternoon.
One thing that separates a properly installed ducted system from a poorly planned one is the attention paid to return air. Every ducted system needs a way to cycle air back through the unit for reconditioning and a single, undersized return air grille is one of the most common causes of restricted airflow, increased running noise, higher energy consumption and shortened system life. We see it all the time when we’re called in to service or replace systems that were installed without enough care.
At Gaschill, we take the time to assess your floor plan and ceiling space carefully so that the return air capacity matches the supply, the duct runs are sized correctly for the zones they serve and the system can breathe properly regardless of which combination of zones is active. It’s the kind of detail that doesn’t show up in a quote comparison but makes an enormous difference to how comfortable and economical the system is over its lifetime.
There are many reverse cycle ducted systems on the market, but the Braemar Dominator Series is the one we recommend and install most often for a straightforward reason: it is the most powerful single-phase reverse cycle ducted system available in Australia for heating performance. Under standard rated conditions it delivers 20kW of heating output from just over 5kW of power input, which translates to close to 400 percent energy efficiency. For larger Melbourne homes that need to heat genuinely substantial floor areas through a cold snap, that performance headroom matters.
The system uses R32 refrigerant, which carries a global warming potential approximately 68 percent lower than the older R410A refrigerant used in many existing systems and typically requires a smaller refrigerant charge to operate. The outdoor unit features Seeley’s Black Magic protective coating on the coil, which provides roughly three times the corrosion resistance of standard coatings, making it well suited to the coastal conditions experienced across bayside Melbourne and the Mornington Peninsula. And with outdoor pipe runs of up to 75 metres possible, there’s genuine flexibility in where the outdoor unit can be positioned on your property.
The indoor unit is also designed to fit into the same ceiling space footprint as a standard ducted gas heater, which makes it a logical and relatively straightforward replacement if you’re transitioning away from gas. Gaschill handles that transition regularly and our team knows exactly what’s involved in making the switch cleanly.
If you’re weighing up whether a ducted reverse cycle system is the right call for your home, it helps to understand where it sits relative to the alternatives.
Compared to evaporative cooling, a reverse cycle system works effectively regardless of humidity, which matters during Melbourne’s sticky late-summer evenings when evaporative systems often struggle to keep up. Reverse cycle also handles heating, which evaporative cooling cannot do at all.
Compared to split system air conditioning, a ducted system offers whole-home coverage through a single system without the need to install and maintain multiple individual units across different rooms. For homes with four or more bedrooms, the economics and the practicality of a ducted approach often outweigh the higher upfront cost.
Compared to a gas ducted heater paired with a separate cooling system, a reverse cycle ducted setup consolidates two appliances into one, reduces ongoing maintenance requirements and takes advantage of electricity rather than gas, which aligns with both the Victorian Government’s broader electrification direction and the potential to offset running costs through rooftop solar.
It’s also worth noting that the Victorian Government has active rebate programs for eligible heating and cooling upgrades, which Gaschill can help you navigate. You can find current information on the Victorian Government air conditioning rebates page on our site.

They recently installed a heat pump water heater for me and I couldn’t be happier with the experience. I spent time researching both price and model, and this company offered the best option. After finalizing my rebate application, they were able to replace my old water heater within just two days, which was much faster than what I had read in reviews about other companies where customers waited much longer. The installation was smooth, the workmanship was excellent, and the team was friendly and professional throughout the process. Highly recommended!

The team at Gaschill are amazing to work with! From my initial enquiry with Tee about air conditioning, he provided excellent customer service explaining what would best suit our needs and responding promptly to all our emails.
Liam, Jack, and Brandon did an incredible job installing our multihead split system a few days ago. They arrived on time, were polite, thorough, and worked efficiently. They even cleaned up all the mess after finishing the job! You can really see how experienced and dedicated they are in what they do.
I would highly recommend Gaschill to anyone looking to install a split system for heating or cooling. Fantastic service from start to finish, thank you guys! My dad is a very happy man!
