Professional Ducted Gas Heating Installation You Can Trust
A ducted gas heating installation is one of the most significant home improvement investments a Melbourne homeowner can make. Get it right and you have a system that heats your entire home efficiently and reliably for 15 to 20 years. Get it wrong and you are dealing with uneven heating, high energy bills, safety compliance issues and a system that needs replacing far sooner than it should.
Gas Experts Melbourne takes care of every aspect of the installation from start to finish. We carry out a free in-home assessment to correctly size the system for your home, supply the unit from all major brands, complete the full installation to Australian Standards, and hand over a certificate of compliance and written report before we leave.
Whether you are installing ducted heating for the first time, replacing an ageing system that has reached the end of its life, or upgrading to a more energy-efficient model to take advantage of Victorian Government rebates, we make the process simple, safe and straightforward.
Why Melbourne Homeowners Choose Ducted Gas Heating
Is Now the Right Time to Install Ducted Gas Heating?
Consider installing or replacing your ducted system if any of the following apply:
Your current system is over 15 years old.
Most ducted gas heating systems have a functional lifespan of 15 to 20 years. A system approaching or past this age is likely to require increasingly frequent and expensive repairs. We can help you assess whether repair or replace is the right decision.
Your system is failing to heat the home properly.
A system that runs constantly without reaching the set temperature, heats unevenly, or has had multiple repairs in recent years is approaching the end of its service life.
You have no ducted heating and are relying on individual room heaters.
Running multiple individual heaters across the home is less efficient than a single ducted system. If your home has roof access suitable for duct installation, a ducted system will typically deliver lower running costs and significantly better whole-home comfort.
You are renovating or building.
Installation is most cost-effective when the roof space is accessible. During a renovation or new build, duct runs can be planned into the construction, reducing complexity and cost significantly.
You want to access Victorian Government energy efficiency rebates.
Eligible homeowners upgrading to a new high-efficiency ducted gas system may qualify for rebates under the Victorian Energy Upgrades (VEU) program. These rebates can substantially reduce the upfront cost of a new installation.
How Our Ducted Gas Heating Installation Process Works
- 1
Before we quote, we carry out a free in-home assessment. We inspect the roof space for suitability, assess the home's floor area and ceiling height, review existing gas connections and determine the correct system size. You receive a recommendation and a fixed-price quote, not a ballpark figure.
- 2
We present you with recommended options across brands and star ratings that suit your home's size and your budget. We are honest: we will not push you toward a more expensive system than you need. We explain the differences in plain terms so you can make an informed decision.
- 3
Our licensed gas fitters arrive at the agreed time and carry out the full installation. For a standard like-for-like replacement of an existing ducted system, installation typically takes one day. A new installation in a home without existing ducted heating may take one to two days depending on the complexity of the duct run.
- 4
Once the system is installed, we commission it, starting it up, running it through its full operating cycle, checking the gas pressure, testing the zone controller and confirming every vent is delivering heated air correctly.
- 5
Every installation includes a full carbon monoxide combustion test and gas safety inspection before we leave. You receive written confirmation that the system is safe to operate.
- 6
We walk you through how to operate the system and zone controller. You receive a written completion report, a certificate of compliance, and assistance with warranty registration where applicable. Your installation is fully documented from day one.

What Size Ducted Heating System Does Your Home Need?
Getting the system size right is one of the most important parts of the installation. System output is measured in megajoules per hour (MJ/h).
By Home Size (approximate)
| Home Floor Area | Recommended Output Range |
|---|---|
| Typical System | Up to 150m2 |
| 60 to 80 MJ/h | 3 to 4 star rated system |
| 150 to 250m2 | 80 to 120 MJ/h |
| 4 to 5 star rated system | 250 to 350m2 |
| 120 to 160 MJ/h | 5 to 6 star rated system |
| Over 350m2 | 160 MJ/h+ |
| 6 star rated or multiple zones | Factors that affect correct sizing: |
- Ceiling height higher ceilings increase the volume of air to be heated
- Insulation level well-insulated homes require less output
- Number of windows and glazing type
- Number of zones
- Home orientation
Our free in-home assessment takes all of these factors into account. We do not quote based on floor area alone.
Honest, Upfront Installation Pricing
We provide fixed-price quotes after the free in-home assessment. No hourly rates. No surprises.
