Gas out, reverse cycle in

Replace gas ducted heating with reverse cycle in Melbourne, with the Victorian discount arranged for you

The gas ducted heater comes out of the roof or from under the floor, a licensed gasfitter caps the line, and a ducted reverse cycle system heats and cools every room from the same outlets. FreshDuct arranges your VEU discount through our accredited installation partners. Free estimate over the phone, firm price from the office, and you pay after the job.

Reasons Melbourne homes are taking the gas heater out

Tick two or more and it is time to book — every one of these gets worse, never better, on its own.

A gas bill that jumps every June and a heater that only gets the house warm by lunchtime
A ducted heater from the 1990s that has been repaired twice and is now waiting on a part nobody stocks
Gas heating in winter, splits or an evaporative cooler in summer, and two systems to service
A heater that has been shut off as unsafe and a cold house until something replaces it
You have heard about the Victorian discount and every quote seems to describe it differently
A rental property with a tired gas heater and a tenant asking about cooling
Underfloor ducts in a brick veneer and no idea whether they can be reused
A quote that mentioned reusing the old ducts without anyone getting into the roof

What the Victorian discount needs from your old heater

The Victorian Energy Upgrades program gives an upfront discount when a gas ducted heater is replaced with an efficient reverse cycle system. It is not a rebate you claim afterwards and it is not money from us; it comes off your quote before you pay. FreshDuct arranges it through our accredited installation partners, and it has to be arranged before any work starts, not after.

The conditions that matter. The gas ducted heater must still be connected to the gas supply and must be the main heating in the home. A heater that was pulled out last year does not qualify. The system being replaced must be more than two years old. The new unit must be on the Victorian register of approved products, must heat as well as cool, and must carry a five year manufacturer warranty. Every Victorian household and business is eligible, including private rentals with the landlord’s approval. A minimum co-payment always applies, so nobody can honestly tell you the system costs nothing.

The figures. The indicative discounts are published by the Victorian Government and move with the market, so we do not print them here. The office confirms yours on the quote, with the discount already taken off. Our VEU heating and cooling discount page explains how the discount works, and our gas ducted to reverse cycle guide covers the background.

Decommissioning the gas heater: capped, removed, photographed

Under the program the old heater cannot simply be switched off and left in the roof. It has to be made permanently unusable, the gas line has to be capped, and the installer has to photograph the result. We do all of it on the day.

The gas side. The gas line to the heater is disconnected and capped by a licensed gasfitter. Only the heater line is touched; a gas cooktop or hot water service stays connected unless you decide to move those too. If the ducted heater was the last gas appliance in the house, we will tell you, because the daily supply charge on a gas account with nothing on it is worth a conversation with your retailer. Our gas disconnection guide goes into that.

The heater. In a weatherboard or a period home the heater usually sits in the roof space near the manhole. In a 1970s or 1980s brick veneer it is often under the floor with outlets in the floorboards. Either way it comes out and is taken away, and the space it leaves is where the fan coil goes on a roof-mounted system. If there was an old add-on cooling unit bolted to the heater, the refrigerant in it is recovered by an ARC-licensed technician before it goes anywhere.

The photos. The program requires a photo record showing the old heater rendered unusable. You get those photos, along with the before and after shots we take on every job, so you can see the capped line and the empty roof space for yourself.

The ductwork decision: what we look at before we say reuse

This is where changeover quotes go wrong. The program guidance recommends replacing the ductwork and fittings when a gas ducted heater becomes ducted reverse cycle, and it says so because the two systems ask different things of the ducts. A gas heater pushes a small volume of very warm air through narrow runs. A reverse cycle fan coil moves a much larger volume of air at a gentler temperature, and in summer that air is cold and the duct has to be insulated well enough not to sweat in a hot roof. Duct that was adequate for gas is often undersized, under-insulated or simply worn out for reverse cycle.

We have spent fifteen years inside Melbourne roof spaces cleaning and inspecting ducts, so we do not guess. Before the quote is confirmed, we look at every run and photograph it: the insulation thickness, the joints, whether the flex has been crushed by stored boxes or chewed by possums, how the outlets are sized, and where the return air grille sits. Sound, well sized, well sealed duct with a good return can sometimes stay. Underfloor duct feeding floor outlets is the case we most often end up replacing, and it is one we decide only after looking.

Whatever we find, you see the photos and get a plain recommendation. If new ducts are the right answer we say so up front, and the office builds them into the firm price. We will not quote reuse to win the job and change our mind on the day.

Ducted reverse cycle, a multi-split or four singles: three ways to replace one gas heater

The Victorian program recognises three replacement paths for a ducted gas heater, and the right one depends on the house rather than the discount.

Ducted reverse cycle is the like-for-like path: one fan coil in the roof, every room from ceiling outlets, zones on the controller. It suits most three and four bedroom homes with a usable roof space and is what our ducted reverse cycle page covers in detail.

A multi-split is one outdoor unit feeding wall heads in two to five rooms. Under the program every indoor unit has to come from the same manufacturer as the outdoor unit. It suits period homes with no roof space for a fan coil, homes where only some rooms need conditioning, and anyone who wants each room on its own remote. Our multi-head page explains it.

Four single splits, typically one larger head in the living area and three smaller ones in bedrooms, is the path when the outdoor units can be spread around the house and the walls are easy. It gives each room independence at the cost of more outdoor units.

On the call the office asks about the roof space, the rooms you actually use and the walls, and recommends one path. The discount differs between the three, and the office confirms the figure on the quote rather than on this page.

What you actually get

What a gas-to-reverse-cycle changeover includes

Every line below is part of the job and part of the price the office confirms.

Included as standard

  • A licensed gasfitter to disconnect the heater and cap the gas line
  • The old heater removed from the roof or underfloor and taken away, with the photo record the program requires
  • A licensed electrician for the new dedicated circuit and switchboard work
  • An ARC-licensed technician for the refrigerant pipework, vacuum, pressure test and commissioning
  • A ducted reverse cycle system listed for the Victorian discount, sized from the plan and the roof
  • Every existing duct inspected and photographed, and replaced where it should be
  • The VEU discount arranged through our accredited installation partners and taken off your quote
  • Before and after photos of the roof space, the outlets and the outdoor unit

And the things we will not do

  • Tell you the old ducts are fine without getting into the roof
  • Promise a fixed discount figure before the office has confirmed your quote
  • Cap a gas line with anyone other than a licensed gasfitter
  • Tell you the system costs nothing – a minimum co-payment always applies
  • Start any work before the discount has been arranged – the program requires it first
How it works

From a gas heater to heating and cooling in every room

1. Tell us about the heater

Where it is, how old it is, whether it still runs on gas and how many rooms it feeds. The office gives you a free estimate over the phone.

2. Discount confirmed, price confirmed

The office checks your eligibility, arranges the discount through our accredited installation partners and confirms the firm price with the discount taken off, before any work.

3. Changeover day

Gasfitter caps the line, heater out, fan coil and outdoor unit in, ducts replaced where they should be, circuit wired, system commissioned and zoned.

4. Photos, then you pay

You see the capped line, the cleared roof space and the finished system in photos, and pay only after the job.

Straight answers

Gas-to-reverse-cycle questions, answered straight

Can I get a discount in Victoria for replacing my gas ducted heating with electric?

Yes. The Victorian Energy Upgrades program gives an upfront discount when a connected gas ducted heater that is the main heating is replaced with an approved reverse cycle system. FreshDuct arranges it through our accredited installation partners and it comes off your quote. The indicative figures are published by the Victorian Government and the office confirms yours.

Does my gas heater need to still be working to qualify?

It needs to be connected to the gas supply and be the main heating in the home. A heater that was removed or disconnected some time ago does not qualify under the replacement scenarios. If yours was shut off for a safety reason, tell the office, because that case is treated differently and we check it before quoting.

What can I replace my gas ducted heating with?

Three paths carry the Victorian discount: a ducted reverse cycle system using ceiling outlets, a multi-split with one outdoor unit and heads in several rooms, or four single split systems. A like-for-like gas heater is also possible but carries no discount. The office recommends one path after asking about the roof space and the rooms you use.

Is reverse cycle cheaper to run than gas ducted heating?

A reverse cycle system moves heat rather than burning fuel to make it, so each unit of electricity delivers several times the heat of a plug-in electric heater. Whether your bill drops depends on your tariffs, insulation, zoning and how you run it, so we do not promise a figure. The Victorian Government publishes indicative bill savings alongside the discounts.

Can my old ducts be reused for the new system?

Sometimes. The program guidance recommends new ductwork on gas-to-reverse-cycle changeovers because reverse cycle moves more air at a lower temperature. We inspect and photograph every run before the quote is confirmed and tell you which can stay. Underfloor ducts feeding floor outlets are the runs we most often end up replacing.

Do I have to disconnect gas from the whole house?

No. Only the line to the ducted heater is capped, by a licensed gasfitter. A gas cooktop or hot water service stays as it is. If the heater was your last gas appliance, it is worth talking to your retailer about the supply charge on an account with nothing connected to it.

Can I get the discount as a renter?

Yes. Private rental properties are eligible under the program, but heating and cooling upgrades need the landlord’s approval. For a landlord, the discount makes replacing a tired ducted heater with a system that also cools an easier decision, and cooling is a common tenant request. The office can talk to the property manager directly.

Is a reverse cycle system warm enough for a Melbourne winter?

Yes, when it is sized properly. Systems listed for the Victorian discount must meet a cold-climate heating efficiency rule, so they are built to heat on a frosty Melbourne morning, not just cool in February. The sizing and the ductwork matter more than the brand, which is why we look at the house before quoting.

Should I wait until my gas heater dies?

We would not. The discount needs the heater still connected, so a heater that has already been pulled out loses it. A heater that fails in June also forces a rushed decision in the coldest month. Planning the changeover in autumn or spring lets you choose the path calmly and book a day that suits you.

Free estimate over the phone, firm price before any work, pay after the job.

Gas ducted heating to electric: the Victorian discount

The Victorian Energy Upgrades program takes an upfront discount off the quote when a connected gas ducted heater that is the main heating is replaced with an approved reverse cycle system. FreshDuct arranges it through our accredited installation partners. The indicative figures are published by the Victorian Government and the office confirms yours on the quote, with a minimum co-payment always applying.

Gas heater decommissioning by a licensed gasfitter

Under the program the old heater must be made permanently unusable and photographed, and the gas line must be capped. A licensed gasfitter does the gas side; the heater comes out of the roof or from under the floor and is taken away; you receive the photo record and our before and after shots.

Ductwork on a gas-to-reverse-cycle changeover

The program guidance recommends new ductwork and fittings when gas ducted becomes ducted reverse cycle. After fifteen years inspecting and cleaning Melbourne ducts we agree, and we photograph every run before the quote is confirmed so you can see why a duct stays or goes.
