As Australia’s weather becomes more and more unpredictable, a reliable heating and cooling system is more important than ever. Of the numerous options available, ducted gas heating continues to be a popular choice for Melbourne homes and businesses. However, like any system, it needs regular attention to perform at its best. 

Whether you’re dealing with cold air blowing through the vents, odd noises, or strange smells, knowing who to call and what’s involved in a service can make all the difference. In this guide, we’ll cover everything you need to know about ducted gas heating servicing, from who should be handling them to the key benefits of maintaining your system.

Let’s jump into it!

Who Can Handle a Ducted Gas Heating Service?

When your ducted gas heating system needs attention, it’s not something to be left to the untrained. As noted by the Australian DCCEEW, “servicing should be done by a licensed technician.” (Source)

Why is this so important? Unlike portable heaters, ducted systems are complex and involve components that can pose safety risks, especially if mishandled. That’s why you should always hire licensed and experienced gasfitters who have the training required to understand the technical specifics of your system. 

At Maroondah Air Services, our technicians have been working with ducted heating systems for over 25 years. Every member of the team knows their way around the burners, fans, and ducts that keep your home warm and comfortable. The entire Maroondah Air Services team is well-trained and operates in accordance with OHS requirements.

A Quick Guide to Type A and Type B Gasfitters

Not all gasfitters are the same, and we can explain this by quickly outlining the difference between Type A and Type B gasfitters in Australia. 

Type A gasfitters are qualified to work on most domestic appliances, including your typical ducted gas heating systems. They also have the necessary training certification to handle things like the gas connections, burner systems, and basic maintenance tasks. On the other hand, Type B gasfitters are trained for larger, industrial-scale gas appliances—think boilers and commercial gas systems. 

If you’re booking a service for your home, a Type A technician is usually all you need. At Maroondah Air Services, we have fully licensed Type A gasfitters who are well-versed in ducted systems–and if you ever need help with something more complex (like checking for gas leaks or testing the system for carbon monoxide), our team has the skills to keep your home safe.

The Benefits of Regular Servicing

In the past, ducted systems were primarily used during the autumn and winter months. However, since the introduction of add-on cooling, they’ve become much more of a year-round climate solution. This makes the need for regular servicing even more vital.

1. System Efficiency

Because ducted heating and cooling is such a significant investment, no one deserves to settle for an inefficient system. Remember, any underlying issues tend to lead to sub-par performance and higher utility bills.

Over time, dust, dirt, and debris will build up in your ducts, clogging airways and causing the system to work harder than it should. This puts more of a strain on the components, which may then affect how evenly your home is heated or how long it takes for the system to kick into gear. 

During a routine service, technicians will clean out the ducts, burners, and fans to make sure that air flows smoothly through your system. After everything is cleaned and cleared, your system won’t have to work overtime just to keep your home warm. In turn, you’ll enjoy a home that heats up faster and stays warm for longer. 

Regular servicing allows technicians to detect potential issues that could affect performance, keeping your system running efficiently all year long.

2. Lower Bills

An efficient ducted gas heating system is designed to keep you comfortable–but that doesn’t mean you have to pay an arm and a leg just to keep it operating. Although energy prices have risen across the board in the state of Victoria, a well-maintained system is much less likely to leave you with hefty bills.

When the system is clean, fully functional and well-maintained, it uses less gas to achieve the same results. If the system is struggling due to blocked ducts or failing components, it has to work much harder, which ultimately drives up gas consumption. 

During a service, an HVAC technician will use cutting-edge diagnostic tools and equipment to identify any underlying issues. If issues are present, they will be able to provide on-the-spot repairs or provide recommendations for the action required.

Over time, these small savings add up, especially during Melbourne’s colder months when heating is on full-time.

3. Safety

Safety and gas heating should always go hand-in-hand. Over time, components may wear down, and the risk of dangerous gas leaks (such as carbon monoxide) increase. Although it is both odourless and colourless, carbon monoxide can be deadly if undetected. This is why a professional ducted gas heating service will involve checks for any leaks and above all, verifying that everything is safe for use.

At Maroondah Air Services, our technicians are trained to test for carbon monoxide leaks, which can occur due to faulty burners or cracked heat exchangers. If any safety concerns arise during the inspection, we’ll walk you through what needs to be done and make sure you or your tenants are safe.

4. Preventing Costly Repairs

A regular service can save you from the headache of emergency breakdowns. Catching small issues early, like a faulty fan or blocked duct, will prevent more significant problems down the line. 

The longer a problem is left unaddressed, the more strain it puts on the system, which could eventually lead to costly repairs or even a complete system replacement. For instance, if a blower motor starts to wear out, it could lead to uneven heating or excessive noise. Addressing this early on is far more affordable than replacing the entire unit.

 Routine check-ups also keep your warranty intact, giving you coverage if larger repairs are needed. The bottom line? Regular servicing prolongs the life of your system and saves you money in the long run by tackling underlying issues head on.

5. Replacing Key Components

Even with regular maintenance, some components of your ducted gas heating system will eventually need replacing. Parts like the thermostat, burners, and air filters can all wear out over time and affect your system’s overall performance.

So, if you notice that your system isn’t heating your home as effectively, or if you’re constantly adjusting the thermostat, it could be time for a key component to be replaced. Our technicians will be able to assess each part of your system, then let you know if anything needs replacing before it becomes a bigger problem. 

With upfront quotes and clear communication, the Maroondah Air Services team will be there to guide you through the entire process and provide a clear picture of the costs involved.
