Heater Repair & Replacement Melbourne

Fixed Price - Local Expert

When a heater — or central heating system, as it's also commonly called — stops working, the first question is almost always the same: is this worth repairing, or should I be looking at a new system? The Heater Repairman exists to answer that question honestly. We're a specialist heating and cooling technician serving Melbourne's eastern, southeastern and northeastern suburbs from our Ferntree Gully base, with over 35 years of hands-on experience across every major brand and heater type. Our approach starts with repair, not replacement — we only recommend a new system when it genuinely makes more sense than fixing what you've got.

Signs you need heater repair or replacement

Your heater has stopped working completely, or turns on but produces no warm air
The system heats some rooms but not others, despite zone controls being set correctly
You can smell gas, sulphur or a burning odour when the heater runs — turn it off and call immediately
The heater runs briefly then shuts itself off before the home reaches the set temperature
Your controller is displaying a fault code, error light, or the screen has gone blank
The system makes loud banging, rattling or grinding noises on start-up or during a cycle
Your gas bills have risen noticeably compared to the same period last year with no change in usage
Your heater is 10–15+ years old and performance has gradually declined over recent winters

Not sure if your issue is a full breakdown or something less urgent? Our Heater Repair & Replacement page walks through how to weigh up repair versus replacement if it's not an emergency

How to decide between repair and replacement

This is the question we get asked most, and the honest answer depends on three things: the age of the system, the nature of the fault, and the cost of the repair relative to a new unit. As a general rule, a heater under 10 years old with a straightforward fault — a failed ignitor, a faulty thermostat, a worn fan motor — is almost always worth repairing. Once a system passes the 15-year mark, or the fault involves a cracked heat exchanger (a safety issue, not just a performance one), replacement usually becomes the more sensible long-term option. We'll walk you through the real numbers on your specific system rather than pushing you toward whichever option is more profitable for us.

Frequently asked questions

How much does heater repair cost in Melbourne?

The Heater Repairman charges a fixed price of $250 + GST + parts for all repairs, regardless of how long the job takes. This means no surprise bills - you know the labour cost upfront.

How do I know if my heater needs repair or replacement?

If your heater is under 15 years old and develops a fault, repair is almost always the more cost-effective option. If it's over 15 years old, has a cracked heat exchanger, or requires repeated expensive repairs, replacement may be the better long-term investment. We'll always give you an honest recommendation.

How long does a heater repair take?

Most heater repairs are completed in 1–2 hours on the first visit. We carry common parts, so many faults are resolved same-day. If a specific part needs to be ordered, we'll advise you of the expected turnaround time.

Do you repair all heater brands?

Yes - we repair all major brands including Brivis, Braemar, Bonaire, Vulcan, Lennox, Omega, Kaden, Rinnai and more. With 35+ years of experience, we've worked on virtually every ducted gas heater system installed in Melbourne's eastern suburbs.

What's a cracked heat exchanger, and why does it matter?

A heat exchanger separates the combustion process from the air blown into your home. If it cracks, combustion by-products including carbon monoxide can potentially enter your living space, which makes it a safety issue rather than just a performance one. This is one of the few faults where we'll always recommend replacement over repair.

Do you offer a guarantee on your repairs?

Yes. We stand behind our work with a satisfaction guarantee on every repair. If the same fault recurs after our repair, contact us and we'll make it right.
