How Long Does a Gas
Ducted Heater Last?

The lifespan of your ducted gas heater depends on how well you maintain and service it. A ducted gas heating system can last anywhere between 10 and 20 years, with the average life expectancy being 15 years.

There are three key factors that will impact the lifespan of your ducted gas heater:

Quality – Ducted gas heating systems across the market will vary in quality. Opting for a lower-end heating unit may reduce upfront installation costs, but cheaper systems will need replacing sooner.

Model – The type and model of ducted gas system you choose will impact its lifespan. An undersized heating unit will have to work harder to heat your home efficiently, meaning it will wear out more quickly.

Maintenance – Proper maintenance is key to the longevity of your gas ducted heater. Annual gas heating servicing and proactive maintenance gives it the best chance at a long lifespan.

It’s also important to have any issues with your heating system inspected and repaired as quickly as possible to avoid deterioration. Most parts of a ducted gas system can be repaired or replaced easily, which can help prolong the system’s lifespan.

Depending on your heating unit’s condition, though, it can be more cost-effective to replace the system altogether. The latest gas heating units on the market are far more energy-efficient than older models – meaning the energy savings can quickly balance out the cost of a replacement.

Why Replace My
Ducted Gas Heater?

If your old gas heater is starting to struggle, you may be considering the benefits of replacing it. Up-to-date heating units from Brivis, Braemar and Lennox offer superior performance and energy-efficiency.

Some of the great reasons to replace your gas heating system include:

Modern Efficiency Rating

Old gas heating units have a lower efficiency rating compared to newer models. By continuing to run an old heater, you’ll be missing out on the energy savings up-to-date heating systems offer.

Avoid Repair Costs

If your heating unit is more than 10 years old, key components will be wearing out - and even if parts don’t need replacing yet, they’ll inevitably need fixing over the next 5 to 10 years. It can be far more cost-effective to install a new energy-efficient heater than to keep an old one ticking along.

More Effective & Reliable

Up-to-date gas heating units offer much greater performance, heating your home more quickly and evenly. Especially if your existing unit isn’t sized correctly, you’ll see a drastic difference when you replace it with a modern gas heater.

Environmentally Friendly

In addition to using up to 30% less energy, a modern 6 Star gas heating system emits up to 75% fewer greenhouse gases than electric heating. Upgrading to a new gas heating unit remains far better for the environment than electric heaters.

Safe For Your Family

A more serious concern is whether an old heater is affecting you or your family's health. Carbon monoxide leaks can occur as your heating unit deteriorates, and older ducted heating can also impact indoor air quality. Symptoms of carbon monoxide poisoning include headaches, dizziness, shortness of breath or nausea. In some cases, CO leaks can even be deadly. Many of our Sydney customers choose to replace older heating systems to ensure the family home is a safe environment.

Silent operation

Ducted gas heating systems are some of the quietest on the market. You won’t be disturbed by any noise coming from the system, even if it’s running all day. It’s a comfortable and discreet way to keep your home heated.

If your gas heating system is wearing out, it may pose a safety hazard. Replacing your old gas heating unit with a new, energy-efficient model ensures it’s both safe and cost-effective to heat your home.

How Do I Know If My
Gas Heating System Needs Replacing?

There comes a time when your run-down heater is beyond repair, or it isn’t cost-effective to fix. But how do you know if it’s time for a replacement?

Signs your ducted gas heating may need replacement include:

Repairs are too frequent or too expensive

Energy bills are increasing

Visible damage or wear

Heats slowly or unevenly

Strange noises coming from heater

Gas or carbon monoxide leaks

Temperature needs adjusting constantly

If your heater is experiencing one or more of these symptoms, book an assessment with Alliance Climate Control. Our expert technicians across Sydney can advise whether your system can be repaired, or if it’s better value to replace the heating unit.

When your heater is requiring regular repairs, or heating performance has gone downhill, it may be time to bite the bullet and replace your gas heating unit. Upgrading to a new model ensures you’ll be heating your home cheaply, efficiently and safely this winter.

If it’s time to replace your ducted gas heater, the experts at Alliance Climate Control can help. Call us today to book your assessment and quote.

How Much Does It Cost
to Replace a Ducted Gas Heater?

The replacement price of a ducted gas heating unit varies depending on several factors. Luckily, a replacement or upgrade is significantly cheaper than installing a brand new heating system from scratch.

If you are just replacing a broken gas heating unit, you should already have the ducting, vents and controls in place which will cut back a lot of costs. However, if there are internal parts that are outdated or inefficient, it may be better to replace these.

Damaged ductwork can undermine the performance of your heating system and increase running costs. However, the lifespan of ductwork is often longer than the gas heater itself, and they can also be patched or repaired.

The model, manufacturer, and kilowatt output of your new and existing ducted heating system will be the major factor when it comes to cost.

However, all homes are different, and you’ll want to ensure the heating unit is appropriately sized. This means the best way to determine the cost of replacing your gas heating is to get a personalised quote from a Sydney gas heating professional.

Our expert team can calculate exactly which gas heating unit is best for your property’s layout. To book your obligation-Upfront Quote, call Alliance Climate Control today.

Cm3 certification is a Work Health & Safety (WHS) prequalification system.

Using a Cm3 certified technician is crucial to ensuring you and your project are in safe and protected hands.

How Much Could You Save By Upgrading
Your Gas Heater?

Ducted gas heating systems are much more efficient, and they’re designed to comply with modern environmental standards. A 6-star rated Brivis gas heater saves Aussie households an average of $567 a year, when compared to old 3-star models.

If you’re upgrading your gas heater, a higher star rating means it’s more energy efficient – meaning you’ll save more on your annual running costs. While upgrading to a newer model does come at an upfront cost, this is quickly offset by reduced running costs within years.

The more energy-efficient your new heating unit is, the more savings you’ll keep in your pocket this winter.

Brivis research shows that on average:

A 4 star system uses 13% less energy – annual savings of $236

A 5 star system uses 22% less energy – annual savings of $420
A 6 star system uses 30% less energy – annual savings of $567

*compared to a 3-star gas heating unit.

He was professional, and friendly and answered all our queries and concerns to a T.Harry and his team were fantastic. They are professional, courteous, prompt and hard working. They took care of our wooden floors and carpet and worked very hard throughout the whole time. They also had no problem in removing the big old Brivis heating box and replacing it with the efficient new outlet. In addition, they did a good job of cleaning everything up. They truly are a great team and I highly recommend them.read more

Matt with his team Aiden and Noah installed new aircon equipment for us. They were fast efficient, clean, tidy and hard working. They were also polite and friendly, explaining everything we wanted to know. I recommend them very highly.

Alliance were extremely helpful and professional from the first moment. From enquiring and booking with Zac, to the day of the A/C removal and installation with Jonathan and Thomas, everyone was so courteous and friendly, and the level of... professionalism was fantastic. Wouldn’t hesitate to recommend them!read more

From the initial visit and quote by Lachlan and Zac, through to the installation by Dee and Josh I cant fault this business at all. They were all super professional and lovely to deal with. The boys did an excellent job installing our AC on what was... possibly the coldest and windiest day this year, scaling my house and third story roof to complete the job. They remained upbeat and helpful, fully explaining the whole process to me and leaving the house neat and tidy afterwards. Great service!read more

The customer service support from Zac and Sam was excellent. The professional service of Dee, Rodriquez and Andrea was amazing, they were clean, tidy and efficient. We will definitely continue to use Alliance.

Quick professional and polite. Definitely recommend them

Goran was my first real interaction with Alliance. He was on time and knew every aspect of the job. He was thorough and you felt you were in good hands. Compared to other companies that quoted Goran was just superior in every aspect of his... approach and product knowledge. He knew the system would require a lean to attachment to fit the space, he took time to explain that when asked and was responsive to all my questions. The installation team were polite, on time and did a great job (Martin and Ash) even going out their way to show me the operations of the thermostat and setting it up for me.Thanks so far so good.Andrewread more

Jamie was polite and helpful. Very clear about what the issue was and next steps. I'll definitely call them again if I need help!

The Team from Alliance Climate Control were very professional with my dealing with them. The entire process from the initial call to the installation exceeded my expectations. The Tradesman which came were punctual, cleaned up after they completed... the requires electrical and Air Conditioning works. I have no hesitations in recommending Alliance Climate Control, and will be the first call I make for any future Electrical and HVAC jobs I need.read more

I want to start off by saying THANK YOU.After 9 years living here, we finally have aircons! Big thanks to the Alliancecc team. The boys pulled 2 days of hard work in getting the aircons installed. The job was done professionally and everything is... perfecto~ .We understood from the get go that this was a complex project to start with as we went through multiple companies and none of them managed to come up with a plan that works for us esp when it comes to getting it done in a way that satisfies both aesthetics and practicality. After the job was finished, everything was cleaned up. No mess was made. I have to say I'm absolutely impressed with the level of professionalism with the whole team.Lastly, BIG shoutout to the boys that have helped in pulling this off. Please send our thanks and appreciation to B.J., Zac, Mack, Sam, Kirk, Noah, Shadi, Rodriguez, Peter, Andre, Matt and Ben!read more

Amazing work done by the team today ( Jonathan Thomas and Andres) aswell as Goran and Zac. They have done an amazing job today. Very professional and informative when installing the air-conditioning.

5/5 - wonderful service!

JJ is a real asset to the business. You guys know how to hire the right people. Happy with outcome.

I had a split system installed in my apartment over a year ago and had a similar high quality experience as many others here. A year on and I can confirm that Alliance's maintenance team is just as professional, approachable and effective as their... install crew. Big thanks to Lachlan and Ewan for being incredibly attentive, helpful and kind. Highly recommend this company.read more

Great service. The installers were on time and did a professional job. They asked how I wanted the layout of the installation and did it very well. They also helped me out fixing some other bits and pieces. Special thanks to Dee, Shadi, Rodriguez,... Arron and Tory for the initial inspection and quote. Thanks guys!read more

Thanks to Kevin, Martin and team for installing our A/C back in Feb! Great team & service, highly recommend. Rebecca and Huw.

Great service, Very professional and great products, Attention to detail on Installation. Will defiantly use this company again. Comes highly recommended.Great work B.J , Peter, J.J, Chris & Goran

Matt and Aiden from Alliance handled our recent Multi-split installation at a terrace in the Inner West. They worked tirelessly to get both units installed, took care during the installation to not only get everything placed well, but kept the home... tidy as best they could as well. Two electricians came to do the wiring (sorry, don't have their names), who similarly did a good job in a relatively tricky build (switchboard at back of house, AC units at front).Everything is working well so far and we've been happy with the quality of works. We had used Alliance several years ago for an AC install in an apartment, and that was of similar high quality. We still readily recommend Alliance to friends and family.read more

Prompt polite service

Professional service provided by the whole team I dealt with being Goran, Jonathan, Thomas, and Zac everyone knew their job and performed it exceptionally. Customer service was great and performed with a smile taking time to explain all the work... performed so we were kept informed and understood the entire process.read more

Lads were great, we had Jonathan, Tommy, JJ and Chris do our apartment which was no simple task. All boys were nothing but professional and did the job to what are expectations were and even more. The best part these blocks also showed humanity and... were always up for a good chat. Couldn’t recommend moreread more

Great team thanks Dee, Shadi, Rodriguez, Kirk and Zac for good humor and good quality work.
