Ducted country, but splits still win in a lot of these houses
Split System Installation in Hoppers Crossing
Hoppers Crossing is ducted country. Big flat floorplans, generous accessible roof space, and homes at exactly the age where the original gas heating is on its last legs. If you want the whole house at one temperature from one controller, ducted reverse cycle is the right product and we install it.

The short answer
Split system air conditioning in Hoppers Crossing costs $2,500 to $7,500 installed. These broad single storey 1980s and 1990s floorplans are natural ducted candidates, but where a household lives in one open plan area and only sleeps in the bedrooms, three splits cost far less and heat a single room for roughly 28 to 36 cents an hour. Ceiling insulation from that era is usually still present but rarely still effective, and restoring it often drops a room a full capacity step.

But we are not going to pretend ducted is always the answer. Plenty of Hoppers Crossing households live in the open plan area, sleep in two of the four bedrooms and never set foot in the formal lounge. For them, three well placed splits cost a fraction of a ducted system and give better control over what they actually use.
The honest comparison for a big single storey home
Ducted gives you one controller, hidden equipment, even temperatures and no boxes on the walls. It suits households where the whole house gets used, where there are people home at different times, and where resale matters. It costs more up front and, when the outdoor unit fails, the whole house is without heating and cooling at once.
Splits cost less per room, fail one at a time, and let you condition a single bedroom overnight for a few cents an hour rather than running a whole system. In a four bedroom Hoppers Crossing home where two bedrooms are empty most of the year, that is a real saving both up front and every month.
Choose ducted
Whole house use, multiple occupants on different schedules, accessible roof space, one controller preferred, resale a consideration.
Choose splits
Life happens in one or two rooms, budget matters, and you want independent control and independent failure per room.
Mixed approach
One large head in the open plan living area plus heads in the two bedrooms actually used. The most common Hoppers Crossing outcome.
Insulation from the 1980s and 1990s
Homes of this era were built with ceiling insulation, and thirty years later most of it is still up there in some form. Compressed to half its rated thickness by storage and foot traffic, gapped around downlight cutouts, and usually missing entirely above a later extension or a converted garage.
We check the roof space before quoting a capacity, because this is the single cheapest improvement available on these houses. Restoring the ceiling can drop a living room from 7.1kW to 5.0kW, which saves on equipment, saves every month on running cost, and makes the whole house more comfortable regardless of what system goes in.
Room by room in a typical Hoppers plan
The standard 1980s and 1990s Hoppers Crossing floorplan has a formal lounge at the front, an open plan family and meals area at the rear with sliding doors, and three or four bedrooms off a hallway. Ceilings are 2.4 metres and the rooms are generously sized by modern standards.
The rear family area with west facing sliding doors is usually 5.0 to 7.1kW depending on whether it opens into the hallway. Bedrooms are 2.5kW where the ceiling is properly insulated and 3.5kW where it is not or where there is significant west facing glass. The formal lounge, if it is used at all, is usually 3.5kW. We measure rather than assume, because the same plan behaves differently depending on orientation.
Cost, the VEU discount and the electrical work
A split system runs $2,500 to $7,500 installed depending on capacity and head count. Reverse cycle delivers 3 to 4 units of heat per unit of electricity against 80 to 92 percent conversion for gas, so heating a room costs roughly 28 to 36 cents an hour instead of 50 to 72 cents for ducted gas, saving about $200 to $450 a year.
Victorian Energy Upgrades discounts come off the invoice with no income test, on properties at least two years old, with a $200 including GST minimum contribution. Announced changes commence 30 September 2026 and amounts are confirmed at quote. Each split needs its own dedicated circuit and isolator, and 1980s and 1990s boards here frequently need RCD protection retrofitted first, which is quoted separately.
Refrigerant work is carried out under an ARC licence and the electrical connection under REC 37223, with a Certificate of Electrical Safety issued on completion. Keep that paperwork with your house records, because manufacturers ask for it when a compressor fails in year four and buyers ask for it at sale. Our workmanship is guaranteed for 12 months.
On the ground
Hoppers Crossing specifics
- Broad flat single storey floorplans with accessible roof space make this genuine ducted country, but the household that only uses two or three rooms is usually better served by splits.
- Ceiling insulation from the 1980s and 1990s is normally still present and rarely still effective. Restoring it is the cheapest capacity available and often drops a living room a full step.
- The standard local floorplan puts a formal lounge at the front and a west facing open plan family area at the rear. That rear room is almost always the largest capacity in the house.
- Boards of this vintage usually lack RCD protection on every final subcircuit, so a new dedicated circuit for a split is a good moment to bring the board up to standard.

Answers
Hoppers Crossing questions
It depends on how much of the house you actually use. Ducted gives even temperatures from one controller and suits households where every room gets used. If two bedrooms are empty most of the year and life happens in the open plan area, one large living head plus two bedroom heads costs far less up front and every month. We price both honestly.
On a house of this age, almost always. Insulation installed in the 1980s or 1990s is usually compressed to half its rated thickness, gapped around downlights and missing above extensions. Restoring it can drop a living room from 7.1kW to 5.0kW. That saves on the equipment, on the running cost, and it improves the house whether you install a split or ducted.
Usually 5.0 to 7.1kW in a standard local floorplan, depending on whether it opens into the hallway, how much west facing sliding door there is, and the state of the ceiling insulation. It is nearly always the largest capacity in the house. We measure volume, glazing and orientation on site because two identical plans on different orientations need different units.
Often. Each split needs its own dedicated circuit and isolator, and boards from the 1980s and 1990s here typically have breakers without residual current protection on every final subcircuit. Since we are working in the board anyway, retrofitting RCD protection at the same time costs far less than a separate visit later. It is quoted as its own line.
Around $200 to $450 a year for a typical household. Reverse cycle moves heat rather than making it, returning 3 to 4 units of heat per unit of electricity where a gas system converts only 80 to 92 percent of its fuel. That is roughly 28 to 36 cents an hour per room instead of 50 to 72 cents. Dropping the gas supply charge entirely adds more again.
