Is There An Electric Replacement For Gas Ducted Heating?

Yes. The electric replacement for gas ducted heating is a reverse-cycle refrigerated ducted system. It runs through ducts and vents much like your old gas unit, but it’s powered by electricity instead of gas. The bonus is that the same system also cools your home in summer, so one install handles both seasons.

If you’re a Melbourne homeowner staring down an ageing gas ducted heater, this is the upgrade most people are now choosing. It uses your existing ductwork in many cases, removes a gas appliance from your home, and gives you year-round comfort from a single piece of equipment. If you want the full picture on how to replace gas ducted heating with electric, read on — below we cover how it works, what it costs, the rebate situation, and how to tell if it’s the right move for your place.

Bottom Line

• The direct electric swap for gas ducted heating is a reverse-cycle refrigerated ducted system: one system that heats in winter and cools in summer.

What Is the Electric Replacement for Gas Ducted Heating?

The electric replacement is a reverse-cycle refrigerated ducted system. It’s a single system that delivers warm air through your ducts in winter and cool air through the same ducts in summer. Instead of burning gas to create heat, it moves heat using electricity and refrigerant, which is far more efficient than the old burn-and-blow approach.

Think of it as one box that does two jobs. In winter it pulls warmth from the outside air, even on cold days, and pushes it through your home. In summer it reverses, drawing heat out of your rooms and dumping it outside. That’s why people often just call it “ducted heating and cooling”.

The big practical difference from gas is the gas itself: there isn’t any. No gas burner, no flue, no combustion. For many households that’s the whole point, especially with gas prices and connection charges where they are — which is exactly why electric ducted heating has become the default replacement.

How Does It Use Your Existing Ducts?

In a lot of homes, the ductwork already in your ceiling or under your floor can be reused for the new system. The vents you already have stay roughly where they are, and the new indoor unit connects into that network. That keeps cost and disruption down compared with starting from scratch.

It isn’t automatic, though. We check the duct sizing, layout and condition first. Cooling moves air differently to heating, so ducts that were fine for gas sometimes need resizing, sealing or partial replacement to perform well across both seasons. Honest answer: most homes reuse a good chunk, some need more work than others.

Is a Reverse-Cycle System Actually Electric?

Yes, completely. A reverse-cycle refrigerated system runs purely on electricity, with no gas component at all. That’s what makes it a true electric replacement rather than a hybrid. If your goal is to get gas out of the house, this does it.

It also pairs neatly with solar. Because the system runs on power, any electricity your panels produce can offset the running cost. We won’t oversell that, your savings depend on your solar setup and usage, but it’s a real advantage gas can never offer.

How Much Does It Cost to Replace Gas Ducted Heating with Electric?

A standard 3-4 bedroom Melbourne home typically lands between $6,300 and $10,380 all-inclusive. That figure already includes GST, the VEU rebate and the ductwork, and covers the equipment, the install, removing or disconnecting the old gas unit, and getting the new reverse-cycle system running on your existing duct network where it’s suitable. For the bigger picture on ducted heating and cooling in Melbourne, see our main guide.

Where you sit in that range comes down to a handful of things. Bigger homes need more capacity. Tricky roof access, extra duct work, or upgrading old vents pushes it up. A clean swap into healthy existing ducts sits lower. We give you a fixed quote after looking at your actual home, not a guess over the phone.

One thing worth saying plainly: the cheapest quote isn’t always the real number. Undersized equipment or skipped duct work shows up later as a house that won’t warm up evenly. We’d rather size it right the first time.

What Affects the Final Price?

A few clear factors move the number. Home size and the heating and cooling capacity you need are the biggest. Then there’s the state of your ducts: reuse keeps it lean, resizing or replacing adds to it. Roof or subfloor access matters, as does disconnecting and safely removing the existing gas appliance.

Because we’re licensed mechanical plumbers, the gas disconnection and the refrigerant side are both handled in-house under the one job. You’re not chasing separate trades to make the old gas unit safe and the new system live. That’s part of what the all-inclusive figure covers.

What Rebate Can You Get When Replacing Gas Ducted Heating?

The Victorian Energy Upgrades (VEU) program can offer a rebate when you remove an existing gas ducted heater and replace it with an efficient electric system. The catch worth understanding: the incentive is tied to taking out a working gas ducted heater, so it generally applies to genuine gas-to-electric replacements, not brand-new installs in a home that never had gas ducted heating.

We won’t quote you an exact dollar figure here, because rebate amounts change and depend on your specific situation. Any number you see floating around should be treated as “verify”. Check the current details directly at energy.vic.gov.au, read our VEU rebate information page, or ask us and we’ll point you to where your job sits.

What we can do is make sure your replacement is set up correctly so it qualifies where it’s eligible. Getting the paperwork and the equipment right is part of the job.

Do You Qualify for the VEU Rebate?

The key test is whether you’re removing an existing gas ducted heater. If you are, you’re in the right ballpark for the program to apply. If your home never had gas ducted heating, the rebate path is usually different or not available, so don’t bank on it.

Eligibility rules and amounts shift over time, so treat any specific figure as something to confirm rather than rely on. The official source is energy.vic.gov.au. We’ll flag anything that needs verifying for your particular home before you commit.

Should You Switch from Gas to Electric Ducted Heating?

For most Melbourne homes replacing an old gas ducted heater, switching to a reverse-cycle refrigerated system makes strong sense. You remove a gas appliance, gain summer cooling from the same system, and often reuse existing ducts. The decision really comes down to your home, your energy setup and how long you plan to stay.

Here’s how to think about it by situation.

If you’ve got solar: the case is strong. Your panels can offset the running cost in a way gas simply can’t match. The more daytime power you generate, the better this looks.

If your gas unit is on its last legs: replacing like-for-like with gas often costs similar money while leaving you with a single-season appliance and ongoing gas charges. The electric swap gives you cooling too.

If you rarely use cooling and love your gas: be honest with yourself about that. The electric system still wins on getting gas out of the house, but the dual-season benefit matters less to you, so weigh it on comfort and running costs.

If your ducts are old and leaky: factor in some duct work either way. A new system performs only as well as the network it’s pushing air through.

Frequently Asked Questions

Can a reverse-cycle system really heat a Melbourne home in winter?

Yes. Modern reverse-cycle refrigerated systems are built to heat efficiently in cold conditions, including Melbourne winters. They pull warmth from the outside air even when it’s cold out and push it through your ducts, so your home stays comfortable across the season. The technology has come a long way, and these systems hold their heating output far better than older units people sometimes remember. The trick is correct sizing for your home. An undersized system struggles on the coldest mornings, while a properly specced one keeps up without drama. When we quote a replacement, we size the equipment to your actual home and climate so it performs when you need it most, not just on a mild day. That sizing step is where a lot of cheap installs fall down, so it’s worth getting right.

Will I need to replace my existing ducts?

Often not entirely. In many homes a good portion of the existing ductwork can be reused for the new reverse-cycle system, which keeps cost and disruption down. We assess the duct sizing, layout and condition before quoting, because cooling moves air differently to heating. Ducts that were perfectly fine for gas heating sometimes need resizing, sealing or partial replacement to perform well across both heating and cooling. Some homes need very little duct work, others need more, and we’ll tell you honestly which camp yours falls into after we’ve looked. What we won’t do is install a strong new system onto tired, leaky ducts and pretend it’ll perform. The duct network is what carries the comfort to your rooms, so it gets proper attention as part of the job rather than being treated as an afterthought.

How long does it take to replace gas ducted heating with electric?

Most standard replacements in a 3-4 bedroom Melbourne home are completed within a day or two, depending on the specifics. A clean swap that reuses healthy existing ducts is at the quicker end. Jobs that need duct resizing, tricky roof or subfloor access, or more involved gas disconnection take a little longer. Because we’re licensed mechanical plumbers, the gas disconnection and the refrigerant work are both handled by our own team within the one job, so you’re not waiting around for separate trades to coordinate. We give you a clear timeframe with your fixed quote once we’ve seen the home, rather than a vague estimate up front. The goal is minimal disruption: out with the old gas unit, in with the new electric system, tested and running before we leave. We’ll talk you through what to expect on the day so there are no surprises.

Is electric ducted cheaper to run than gas ducted?

It depends on your home, your energy rates and how you use it, so we’ll give you the honest version rather than a sales line. Reverse-cycle refrigerated systems are very efficient at turning electricity into heat, which helps running costs, and they remove gas connection and supply charges from the equation entirely. If you have solar, the running-cost case gets noticeably stronger, since your own power can offset much of the usage. Without solar, the comparison is closer and comes down to current electricity and gas prices, which move around. What we can say confidently is that you get cooling included for that running cost, which a gas unit never provides. For a number specific to your situation, it’s worth looking at your own energy usage rather than relying on a generic figure, and we’re happy to talk it through.

The Bottom Line

If you’re replacing gas ducted heating, the electric answer is a reverse-cycle refrigerated ducted system: one system that heats in winter and cools in summer, runs on electricity, and often reuses your existing ducts. For a standard 3-4 bedroom Melbourne home, expect an all-inclusive range of $6,300 to $10,380, with GST, the VEU rebate and ductwork already included when you’re removing an existing gas ducted heater.
