The Real Cost of Heating and Cooling Your Melbourne Home in 2026 (And How Much the Government Will Actually Pay Toward It)

If you’ve opened an energy bill this year and felt your stomach drop, you’re not imagining it. Heating and cooling now make up one of the biggest slices of the average Victorian household’s power spend, and a lot of that cost comes down to one simple thing: old equipment working overtime to do a job it was never efficient at in the first place.

Here’s the part most homeowners don’t realise until they start looking into it — the Victorian Government is currently paying a genuinely significant chunk of the cost to fix that problem. Not “up to a small discount if you’re lucky.” We’re talking real money, applied before you even see the invoice.

Let’s get into exactly how it works, what you’re eligible for, and how to figure out which upgrade actually makes sense for your home.

How the Victorian Energy Upgrades program actually pays you

The Victorian Energy Upgrades (VEU) program is a state government initiative, and the mechanics behind it are simpler than most people expect. When an accredited provider installs an approved high-efficiency reverse cycle system, that installation generates tradeable energy efficiency certificates. Providers sell those certificates to energy retailers, and the value gets passed straight back to you as an upfront discount on your quote — not a rebate you claim later, not a form you have to chase up in six months.

As it stands, here’s what that discount currently looks like:

• Replacing a single-room gas heater with an efficient reverse cycle air conditioner: up to $1,610 off upfront, plus estimated savings of up to $460 a year on running costs.
• Replacing a whole-of-home ducted gas heater with an efficient reverse cycle system: up to $5,530 off upfront, plus estimated savings of up to $1,140 a year.
• Upgrading to a heat pump hot water system: up to $630 off upfront, plus estimated savings of around $400 a year.

To qualify, your home needs to be in Victoria and the system you’re replacing generally needs to be more than two years old. Renters are eligible too, though heating and cooling upgrades in a rental property need landlord sign-off first.

One thing worth knowing if you’re on the fence: the government has flagged changes to how multi-split ducted systems are assessed under the scheme, including a proposed increase to the minimum customer contribution for larger installations. Nothing changes overnight, but if you’ve been putting off an upgrade “for next year,” it’s worth getting a quote locked in now rather than waiting to see what shifts.

Split system or ducted — which one actually fits your house?

This is the question we get asked more than almost anything else, and honestly, the answer depends entirely on how your home is laid out and how you actually live in it.

If you’re mainly trying to fix one or two rooms — a bedroom that’s unbearable in January, a living room that never quite warms up in July — a split system is usually the smarter, cheaper starting point. It’s a faster install, lower upfront cost, and you’re not paying to condition rooms you barely use.

If you’re after consistent temperature control across the whole house, or you’re already replacing an old ducted gas system, then ducted air conditioning tends to make more financial sense in the long run — particularly because that’s where the biggest VEU discount sits. We’ve also put together a deeper breakdown of how a full ducted system performs across a typical Melbourne home if you want the technical side of it.

Either way, the sizing matters more than the brand. A unit that’s too small will run constantly and cost you more over time. One that’s too big cycles on and off, which is just as inefficient and a lot harder on the equipment.

Don’t sleep on winter — it’s usually where the real savings are

Everyone thinks about air conditioning in terms of summer, but the bigger cost blowout for most Victorian households actually happens in winter, particularly for homes still relying on old gas heaters. A modern reverse cycle system doesn’t just cool your home in February — it’s genuinely one of the most efficient ways to heat your home through winter, often at a fraction of the running cost of gas.

If you’ve been eyeing an upgrade, the current promotional offer on split systems is worth a look before the colder months hit and installer availability tightens up.

Hot water is the upgrade people forget about

Heating and cooling gets all the attention, but hot water is quietly one of the biggest ongoing costs in an Australian home. Heat pump hot water systems use the same underlying tech as reverse cycle air conditioning — pulling heat from the surrounding air rather than generating it from scratch — and they’re dramatically more efficient than a standard electric or gas storage unit.

Given the government discount available on these systems too, it’s genuinely one of the better value upgrades going, and one we’d recommend checking your eligibility for at the same time as any heating and cooling work, since bundling installations often saves on labour.

What’s actually changing in the next few years

Victoria’s push toward electrification isn’t slowing down. Heat pump technology is increasingly positioned as the long-term standard for both heating and hot water across the state, as gas appliances are progressively phased out of new builds and government incentive programs. If you’re planning to stay in your home for the next five to ten years, upgrading now rather than later means you get the current discount structure, not whatever a tighter future version looks like.

It also lines up with the broader sustainability push you’ll have seen locally — the kind of thing we talk about around World Earth Day and other seasonal campaigns, where the message is consistent: smaller household changes add up to a genuinely large collective impact across Victoria.

There’s also a comfort and health angle worth mentioning

It’s easy to think about this purely as a cost exercise, but temperature control has a real impact on wellbeing too — something we touched on around World Health Day. Homes that swing between extremes of hot and cold aren’t just uncomfortable; they’re genuinely harder on respiratory health, sleep quality, and general day-to-day wellbeing, particularly for older residents and young kids. An efficient, properly sized system isn’t just about the power bill — it’s about the house actually being liveable year-round.

If budget is the main hesitation

We hear this a lot, and it’s a fair concern — a full ducted upgrade is a real investment, even with the government discount applied. The good news is there’s a genuinely affordable, staged path to a more energy-efficient home that doesn’t require doing everything at once. Starting with a single split system in the room you use most, then expanding over time, is a completely reasonable way to spread the cost while still taking advantage of the current rebate structure room by room.
