The system you have
Note the heater brand and model if visible, its approximate age, where the unit lives, and any service history or paperwork you hold.

Before requesting proposals
Give every gasfitter the same heating brief
Your notes define the request; they do not establish appliance condition or safety. A licensed gasfitter still needs to assess the system before confirming scope.
2
What is prompting the decision
Describe the symptoms or reasons - faults, age, a safety concern, or a planned upgrade. What you want fixed shapes whether service, repair or replacement is on the table.
3
Home and ducts
Note the areas the ducts serve, any rooms that never worked well, and the approximate age of the home and ductwork.
4
Household usage
Describe when and how the heating is used. Usage patterns matter when weighing a like-for-like replacement against switching systems.
Property-specific checks
A heating quote is not a safety inspection
Servicing, licensing, flue, carbon monoxide and electrification questions belong in the brief before any work is agreed.
Regular servicing and carbon monoxide testing
Victoria's energy safety regulator recommends servicing gas heaters every two years by a qualified gasfitter, including carbon monoxide testing. Check the guidance and requirements for your own state or territory.
Gasfitting is licensed work
Work on gas appliances, pipes and flues must be performed by a licensed gasfitter. Licensing is state and territory based - check the register that applies to the property.
Flues and ventilation
Safe operation depends on the flue and ventilation around the appliance. Ask who inspects them and what the service covers, and do not block vents or modify flues yourself.
Carbon monoxide alarms
A CO alarm is a backup, not a substitute for servicing. Ask your gasfitter what alarm placement makes sense for your appliance and layout.
The electrification fork
When a gas heater ages, one option is switching to ducted reverse-cycle, which also cools. Compare it honestly against like-for-like replacement using your own usage and equipment.
Asbestos-era ductwork
Older homes can have duct materials from the asbestos era. Do not disturb old ducts; ask for an assessment before replacement work begins.
Scope and delivery
Ask which path the assessment actually supports
Service, repair, like-for-like replacement and electrification are different scopes. These questions surface which one each proposal describes.
Service, repair or replace
Ask what the assessment found, what a service or repair would cover, and what findings would make replacement the safer or more sensible path.
Like-for-like replacement
Ask exactly what a replacement includes - appliance, connections, flue work, controls, commissioning - and what existing parts are reused.
Switching to ducted reverse-cycle
Ask what changes: whether existing ducts can be reused, what electrical work is needed, and how the two paths compare for your home. See the ducted air conditioning page for that scope.
Certification and safety checks
Ask what compliance documentation, commissioning tests and carbon monoxide checks are performed and what records you receive.
Compare like with like
Make each heating proposal answer the same six questions
A total is only comparable when the findings, appliance, gas work and exclusions behind it are visible.
1
Assessment findings
What was inspected, the condition found, and any safety observations that shaped the recommendation.
2
Appliance and capacity rationale
The proposed appliance and how your home, ducts and usage informed the recommendation.
3
Gas work and certification
The gasfitting work included, who performs it, and the compliance documentation you receive.
4
Flue and ventilation scope
What flue, ventilation and clearance work is included or assumed.
5
Commissioning and safety checks
Testing on completion, including carbon monoxide checks, and the records you are given.
6
Warranty, exclusions and changes
Product and workmanship responsibilities, excluded conditions, and the written process for scope changes.
Provider due diligence
Check the provider against the actual job
Marketplace eligibility is not proof of a gasfitting licence, insurance policy or capability for your system. Verify the evidence that matters before hiring.
Gasfitting licence
Check the gasfitter holds the licence class required for the work in your state or territory before anything is opened or disconnected.
Insurance evidence
Ask what insurance applies to the proposed work and request current evidence.
Relevant examples
Ask for examples of comparable gas heating servicing or replacement work.
Who attends
Ask who performs the work, who supervises, and how any electrical or refrigerant trades are coordinated if you are comparing an electrification path.
Written changes
Require findings-driven changes to be priced and agreed in writing before the work proceeds.
Completion documentation
Agree which compliance certificates, test results and warranty documents you receive.

Requesting supplier matches is free and does not obligate you to hire.

FAQ
Frequently Asked Questions
Clear answers to the questions homeowners usually ask before comparing quotes.
1 How often should a gas ducted heater be serviced?
How often should a gas ducted heater be serviced?
Victoria's energy safety regulator recommends servicing gas heaters every two years by a qualified gasfitter, including carbon monoxide testing. Requirements and guidance differ by state and territory, so check the safety regulator responsible for your property and keep the service records.
2 What is the carbon monoxide risk with gas heating?
What is the carbon monoxide risk with gas heating?
A poorly maintained or faulty gas heater can spill carbon monoxide, which is colourless and odourless. Regular servicing with CO testing by a licensed gasfitter is the primary control; a CO alarm is a backup, not a substitute. Stop using a heater and seek advice if you suspect a problem.
3 Should I repair or replace my gas ducted heater?
Should I repair or replace my gas ducted heater?
That is an assessment outcome driven by age, condition, fault history, parts availability and safety findings. Ask the gasfitter what they found, what a repair covers, and what findings would make replacement the safer path.
4 Should I stay with gas or switch to ducted reverse-cycle?
Should I stay with gas or switch to ducted reverse-cycle?
When a gas heater ages you can compare like-for-like replacement against a ducted reverse-cycle system, which also cools. The right answer depends on your usage, tariffs, existing ducts and equipment - compare both scopes for your own home rather than following a universal rule.
5 Who is allowed to work on gas heating?
Who is allowed to work on gas heating?
Gas appliance, pipe and flue work must be performed by a licensed gasfitter, and licensing is state and territory based. Check the licence register that applies to the property, and ask what compliance documentation you receive when the work is done.
6 Can existing ducts be reused if I change systems?
Can existing ducts be reused if I change systems?
Sometimes. Duct age, sizing, insulation and condition determine whether existing ducts suit a new appliance or a reverse-cycle system. It is an assessment outcome, and older homes should have duct materials checked before anything is disturbed.
7 What should a gas heating proposal include?
What should a gas heating proposal include?
Compare the assessment findings, the appliance and capacity rationale, the gasfitting work and certification, flue and ventilation scope, commissioning and carbon monoxide checks, warranty responsibilities, exclusions and the written change process.

How does The Wombat ducted heating request work?
