Is your ducted heating no longer working as well as it should be? Maybe the recent energy bills have been alarmingly high, or maybe certain zones feel cooler than others.
Whatever the case, you’re probably wondering how much it might cost to arrange a service or get it repaired. Although the final cost depends on the system’s age, condition, and size, getting a ducted system checked by a professional technician is always worth it in the long run.
In this article, we’re going to take a look at what ducted heating servicing and repairs currently cost in Melbourne. We will also explain the importance of ongoing maintenance and the telltale signs your system needs a little attention.
A lot of property owners only think about servicing their heating once something goes wrong. In reality, regular maintenance can improve efficiency, extend the life of your system and help you avoid expensive repairs.
As a general guide, gas ducted heating systems should be professionally serviced every one to two years. Older systems, or those that see heavy use throughout winter or summer, may benefit from an annual service.
Components naturally wear over time, and identifying small issues early can help prevent larger failures. If your heater is more than 10 years old, regular inspections become even more important. In this case, it’s definitely worth exploring your options for a replacement or switching to electric.
Note: Rebates are currently available for transitioning from gas to electric, and these are definitely worth exploring.
Just like your car, a heating system will often let you know when something isn’t right. Some of the most common warning signs you’re likely to come across include:

Planning an extension or major renovation? Just bought a home with an existing system? It’s always a smart idea to get your ducted heating assessed beforehand.
Any change to your home’s layout can affect airflow, duct sizing and zoning requirements. A technician can determine whether your existing system is still suitable or recommend modifications to keep every room comfortable.
If you’ve just purchased a new property, we certainly recommend getting the central heating checked. This will set you up well moving forward and help to prevent any nasty surprises down the line.
Higher bills are natural during winter or when the system is being used more regularly. A sudden jump in your gas bill without a clear reason, however, can point to an inefficient heating system.
Dirty filters, worn components, leaking ductwork and faulty thermostats are all factors that force your heater to work harder than necessary. Luckily, a professional service can identify these problems and restore your system’s efficiency.
Unlike portable air conditioners, you can’t simply take ductwork down to your local repairer. From the central thermostat to the outdoor unit, ductwork, air grille, and filters, there are so many components that need to be properly maintained.
Due to their complexity and positioning within your building, they are not something that can be left to the untrained. As noted by the Australian DCCEEW, “servicing should be done by a licensed technician.” (Source)
In Victoria, any work on gas ducted heating systems must be completed by a licensed or registered gasfitter with the appropriate Type A appliance servicing class. As detailed by Energy Safe Victoria, homeowners should always use a licensed gasfitter to carry out gas work and service gas appliances (Source: Energy Safe Victoria).
There isn’t a single price for ducted heating servicing or repairs because every system is different. The final cost depends on the type of work required, how accessible the unit is and whether replacement parts are needed.
As a general guide, Melbourne homeowners can typically expect:
Several factors can influence the final cost, including:
Older heaters often require more time to inspect, and replacement parts may be more difficult to source. In some cases, investing in ongoing repairs may not be the most economical option.
Replacing a clogged filter is very different from repairing a cracked heat exchanger or faulty gas valve. The complexity of the repair plays a major role in the overall cost.
Genuine manufacturer parts usually cost more than generic alternatives, and some older models may have limited parts availability.
Larger homes generally have larger ducted systems with more zones, longer duct runs and additional components to inspect and test during servicing.
Units installed in difficult roof spaces or areas with limited access may require additional labour, which can affect the overall price.
While nobody enjoys paying for repairs, regular servicing is one of the most effective ways to reduce the risk of unexpected breakdowns and keep your heating system running efficiently throughout Melbourne’s colder months.
Other than arranging a gas ducted heating service, your other option is to make the switch to reverse cycle heating and cooling. The good news is that every Victorian household and business is currently eligible for a heating and cooling discount through the Victorian Energy Upgrades program.
As long as the system is approved under the Victorian Energy Upgrades program, has a minimum 5‑year warranty (if for a home), and is a high‑efficiency reverse cycle air conditioner, you will be eligible for a discount.
Significant discounts are also available when you completely electrify your household, which means removing all gas-based appliances from the property. As you can see from the graph below, reverse cycle systems are also more efficient and cost-effective to run in the long term.

Knowing that you need to book a service is one thing, but finding the right HVAC technicians is another task in itself. Of course, you’ll always want to choose a reliable company with the right expertise.
Below, we’ve compiled some factors to consider as you search for a heating and cooling service provider in Melbourne.
The HVAC technicians you hire for ducted heating repairs and servicing must be fully licensed and qualified to work on these appliances (including specific training for gas). In Victoria, technicians should hold relevant gas servicing accreditations, such as Type A Gas Appliance Servicing qualifications.
They should also be registered with the Victorian Building Authority (VBA) and other relevant regulatory bodies.
Heating repairs often involve working in roof spaces and other hazardous areas. A reputable company will follow Occupational Health and Safety (OH&S) requirements to protect both their technicians and your property.
Look for a company with a strong reputation for quality workmanship. Online reviews, testimonials and years of industry experience can give you confidence in their reliability.
Different heating systems have different servicing requirements. Choose technicians with experience working on your brand and model, whether it’s Daikin, Rinnai or another manufacturer.
A reliable company will provide an upfront quote before work begins and explain any recommended repairs. Avoid businesses that rely on vague pricing or unexpected extra charges.
Some companies offer discounts for pensioners, referrals or seasonal promotions. It’s worth asking about any current offers that could reduce your servicing costs.
Trustworthy businesses are honest about the work your system needs, provide transparent pricing and complete jobs as promised. That level of professionalism helps build long-term confidence in their service.
