There’s never a good time for the heater to pack it in, but somehow it always waits for the coldest week of the Melbourne winter, usually the first frosty morning you actually need it. The good news? Most heating faults are common, well understood, and fixable, often on the same day.
The trick is knowing which warning signs actually matter, what a repair should reasonably cost, and when a tired old system is quietly telling you it’s cheaper to replace than to keep patching. This guide walks through all three, based on what our technicians see in Melbourne homes every single winter.
At Climate Control Solutions, we’ve been repairing and servicing heating and cooling systems for over 20 years, with technicians licensed across refrigeration, electrical and plumbing. So whatever your system turns out to need, the person at your door is actually qualified to fix it.
in Melbourne, a routine heater service usually runs $150 to $300 and most repairs land between $250 and $900 depending on the part. Call a technician if your heater won’t start, blows only cold air, trips the power, or you smell gas. Simple things like a flat thermostat battery, a tripped switch or a clogged filter are worth checking yourself in two minutes first. We offer fixed upfront pricing and same-day options, with a free quote within 24 hours.
The warning signs your heater needs attention
Heating systems rarely die without warning. Honestly, most of the callouts we get in July come down to one of six things, and the earlier you catch them, the smaller (and cheaper) the fix tends to be. If your heater won’t start, runs but only pushes out cold air, makes a rattle or grinding noise it never used to, struggles to reach the temperature you set, or throws an error code on the controller, it’s time to book a look.
One of those, the heater running but blowing cold air, is so common we wrote a whole troubleshooting guide on it. It’s worth a read before you pick up the phone.
First, the two-minute checks before you call
A surprising number of “broken” heaters aren’t broken at all. Before you book anything, it’s worth a quick look at:
The thermostat: set to heat, above room temperature, and if it’s battery-powered, swap the batteries. Flat batteries mimic all sorts of faults.
The switchboard: a tripped breaker or a switched-off isolator (often outside near the outdoor unit) is one of the most common callout causes.
The return-air filter: a badly clogged filter chokes airflow and can trip an overheat cut-out. Cleaning it is safe and takes minutes.
Repair, service or replace: what’s the difference?
These three get muddled constantly, and the difference matters because it changes what you should expect to pay. A service is preventative care on a system that still works. A repair fixes a specific fault that’s already stopped it working properly. And replacement only really enters the chat when a system is old, inefficient, and staring down a major repair.
Here’s the honest bit a lot of people don’t hear: pouring $1,500 into a 20-year-old ducted heater rarely makes sense when the Victorian Energy Upgrades (VEU) rebate can knock a serious chunk off a modern, far cheaper-to-run reverse cycle system. If you’re weighing that up, our guide on upgrading from gas to electric runs through the actual running-cost maths. A good technician should walk you through this trade-off before a big repair, not after.
What heating repairs cost in Melbourne
Every fault is a little different, so treat these as ballpark ranges for typical Melbourne jobs rather than a fixed price list. The number that matters more than any range below is the one you get before work starts. We quote on fixed upfront pricing, so you know the full cost after diagnosis, not after the invoice lands.
| Job | What’s involved | Typical cost |
|---|---|---|
| Routine service | Clean, test and tune a working system | $150 to $300 |
| Thermostat / controller | Repair or replace a faulty control unit | $250 to $600 |
| Ignition / pilot (gas) | Fix ignition or pilot faults on gas heating | $300 to $700 |
| Fan or motor | Replace a worn or seized blower motor | $400 to $900 |
| Refrigerant / gas leak | Locate, repair and recharge a reverse cycle system | $400 to $800 |
| Major component | Heat exchanger or compressor, often the repair-vs-replace point | $1,000+ |
What a proper heating service includes
A real service is a lot more than a filter clean. On a typical system we clean or replace the return-air filters, test the thermostat and controls, check the electrical connections, inspect the fan and motor, confirm airflow at the vents, and run the whole thing through a full heating cycle.
On gas ducted heating, the safety side matters most. We check the burner and ignition, inspect the heat exchanger for cracks, and test for carbon monoxide spillage. Energy Safe Victoria recommends a gas heater service at least once every two years, which we’d treat as the bare minimum on anything over a decade old.
Common faults by system type
Different systems fail in different ways. Here’s what tends to go wrong with each of the four we repair most across Melbourne.
Split systems
Temperature inconsistency, weak airflow and noisy operation, usually traced back to filters, sensors or the fan motor. See our split system heating page.
Gas ducted heating
Ignition faults, airflow problems and thermostat issues dominate winter callouts, alongside the all-important heat-exchanger safety check.
Reverse cycle ducted
Zoning faults where rooms stop responding, error codes, and airflow imbalances across the ducted system.
Evaporative cooling
Mostly summer work, but pump issues, leaks and reduced airflow are cheaper to sort in the off-season while calendars are quiet.
When it’s urgent: gas and carbon monoxide safety
If you smell gas, don’t wait for a convenient appointment.
Turn the system off, open windows and doors, avoid using electrical switches near the smell, and call a licensed gasfitter straight away.
The quieter danger is carbon monoxide. You can’t see or smell it, and a cracked heat exchanger can release it into your home. Headaches, dizziness or drowsiness that ease when you leave the house are classic warning signs. This is exactly why the two-yearly service on gas heaters isn’t really optional maintenance; it’s a safety check.

Frequently asked questions
How much does a heater repair cost in Melbourne?
Most heating repairs in Melbourne fall between $250 and $900, depending on the faulty part. A thermostat or controller is usually $250 to $600, while a fan or motor runs $400 to $900. A routine service is cheaper at around $150 to $300. Major components like a heat exchanger start at $1,000+, which is often the point where replacing the system makes more sense. We give you a fixed price after diagnosis, before any work starts.
Why is my heater blowing cold air?
A heater that runs but only blows cold air is usually caused by a thermostat set incorrectly, a clogged filter, an ignition or pilot fault on gas systems, or a fan running while the burner has shut down on a safety cut-out. Some of these you can check yourself; others need a technician. We cover the full list in our guide, Why Is My Heater Blowing Cold Air?
Should I repair or replace my old gas heater?
As a rule of thumb, repair it if the system is under about 10 to 12 years old and the fix is minor. Consider replacing it if it’s older, inefficient, and facing a major repair like a cracked heat exchanger. Because the Victorian Energy Upgrades (VEU) rebate can substantially cut the cost of a modern reverse cycle system (far cheaper to run than old gas ducted heating), replacement often works out better value than a big repair on an old unit.
How often should a gas heater be serviced?
Energy Safe Victoria recommends having gas heaters professionally serviced at least once every two years, mainly as a carbon monoxide safety check. For units more than 10 years old, once a year is safer. Reverse cycle and split systems benefit from an annual service before winter, plus a filter clean every couple of months during heavy use.
Do you offer same-day heating repairs?
Yes. We offer same-day repair options for urgent breakdowns, subject to technician availability and where you are in Melbourne. The fastest way to get booked in is to call or request a quote through our contact page, tell us the symptoms, and we’ll prioritise it.
Which Melbourne suburbs do you cover?
We repair heating and cooling systems right across Melbourne, including Brunswick, Richmond, South Yarra, St Kilda, Knox, Rowville, Narre Warren and the surrounding suburbs. If you’re not sure whether we reach you, check our areas we service page or get in touch and ask.
Is it safe to keep using a heater that smells like gas?
No. If you smell gas, turn the heater off, open windows and doors, avoid using electrical switches near the smell, and call a licensed gasfitter immediately. A gas smell, or symptoms like headaches and dizziness that ease when you leave the house, can point to a leak or carbon monoxide, which is a genuine safety risk, not something to wait on.
What heating systems do you repair?
We repair all the main system types found in Melbourne homes: wall-mounted split systems, gas ducted heating, reverse cycle ducted systems, and evaporative cooling. Our technicians are licensed in refrigeration, electrical and plumbing and service all major brands.
