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. 

Wondering if it’s time to replace your ducted system? Give Alliance Climate Control a call to book your assessment and quote.

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.

We Are cm3
Qualified Contractors

Cm3 certification is a Work Health & Safety (WHS) prequalification system. Being Cm3 certified, means our business has demonstrated the highest-level health and safety capabilities as well as having the right insurances and licences to protect our customers. 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.

Great service from first call to installation. Tommy, Shabi and Miguel have done a great job. Worked carefully, provided lots of information, kept us in the loop about what was being done. Everything tested and system explained. Cleaned up and left in great condition. All round best service we have had from tradespeople.
Terry H.
From the moment Liam arrived to give us a quote the whole process was seamless and so professional. Great price and perfectly designed for our house. I cannot speak highly enough of the installers. Yunus and his team were so accommodating and professional. Perfect installation plus they left the house perfectly clean and tidy and removed all the rubbish. Alliance are big on customer satisfaction and what’s not to like about that. We will be using Alliance again.
Paul S.
The installation of my mother-in-law's split-system went better than expected, a good team with B.J., Daniel and the others, from the quotation to the electrician, doing a quick turnaround with minimal noise and mess. The previous system and all materials were removed along with all packaging. Thanks guys.
John M.
Good job.
Judy
Tommy, Dragan, Miguel, JJ and Peter did the job for me and were great - super efficient, cleaned up well and made sure none of my furniture was damaged, and the aircon works great! Definitely recommend.
Ashok J.
I am very pleased with the professionalism and efficiency of Alliance Climate Control as a company and also want to make special mention of Jake Perri, Zach Grenfel, Tommy and his team who installed the new ducted unit and Harry and his team who resealed the ceiling, for their excellent work.
Gravy 2
Excellent work from team professional and proficient. Tommy, Dragan, Emerson, Ben, Kaspar and Harry
James W
Jason and his team at Alliance were professional, punctual and transparent with all the works and fees required. They were responsive and fast with diagnosing, fixing and servicing our air conditioning units on the same day. They also gave us multiple options to keep costs as low as possible which is wonderful considering all works had itemised pricing so that level of transparency was very much appreciated. Thank you and would highly recommend!
James A.
Even the word “outstanding” wouldn’t be a strong enough adjective to describe the professionalism, responsiveness, thoughtfulness and quite possibly unmatched competence of this organisation. This is the second time I’ve engaged their services to rectify issues with my apartment’s ducted air conditioning system and will absolutely do so again.
Peter C.
Great
Michael K.
This company did a great job in changing over our ageing ducted system. The whole process from the initial enquiry, visit from the technician and the installation team was second to none. Alliance provided regular updates and ensured that communication was clear and costs were transparent. A great example of quality workmanship and professional customer service.
Jennifer L.
Alliance installed aircon to our 2 storey 1970s house. The team - Thomas, Gokhan, Dragan, Emre and led by Yunus, were fantastic, from arriving on time to leaving the house perfectly clean after the installation process. They went about everything professionally and expertly, always keeping us informed as they progressed through the various stages, and clearly explaining how the system would be configured and how it operates. They dealt with challenges such as working at heights, their workmanship inside and out was expert and immaculate. They were a pleasure to have in our home. Our great thanks to Yunus for all his thoughtful guidance and each of the team, who all went out of their way to ensure a remarkable job, exceeding our expectations.
Julian S.
Very professional and thorough. No damage and all mess cleaned up. New air con working flawlessly.
Mitchell R.
Yunus and team were very professional and did a very neat job. Worked late Friday afternoon and evening to get it done.
chris P.
Extremely helpful, the team that installed the New air conditioning fantastic they went out of there way, also cleaning up afterwards. Big shout out to Yunus 👍
Linden D.
The team at Alliance were incredible - professional, helpful and knowledgeable in all aspects of the job. From quote to service on site, the Alliance team made us feel as though we were the most important people in their business. There was no pressure to buy - they simply presented us with options that were both cost effective and were tailored to meet the unique needs of our property. The instal team - Yunus, Gothan and Emie- were incredible. They protected our space with considerable care and did an amazing job - even ensuring our pets were comfortable and not disturbed by the noise of instal, dust or their work. Yunus led his team well and was extremely knowledgeable- happy to share that knowledge with us to ensure we made the most of the air con unit they installed. To be honest the air con unit became less the focus of our experience with Alliance - really my rating is for the Alliance team and their amazing attention to first rate service and focus on the customer as an individual. Did we get a good product and value for money - yes, definitely. But it is the total experience of working with the Alliance team that we will remember and tell others about. Hence this rather long google review. Every word is true. They’re great.
LuLu S
Alliance were recommended to us by friends. James, the sales guy, came out and gave us a few options for our a/c installation. I never, at any point, felt pressured to use their company but I'm glad I did. We chose a multi head Panasonic which suited our house restrictions. You can control it using the normal remote or an App. Which is good for when your kid forgets to turn it off and you aren't home!

The communication was excellent with Alliance every step of the way (sales, accounts, schedulers, installers, electricians etc) and we were very happy with the final installation by Yunus, Gokhan, Dragan and Thomas. Everyone was polite, neat and seemed to know what they were doing.

Alliance were able to the whole job, including electrical work. Very convenient and recommended. Thanks.
Kim H.
I was very happy with very professional work done in installing my aircon units . Very clean & careful with my furniture &unit.The whole crew were good Yumus, Gokhon,Emre plus the units are a lot quieter then expected & I love that they match the outside with colour bond cover over the the pipe. They had all the diagrams & certificates for strata & also electricians. So have no trouble recommending this company.
indra A.
Andres R/Ivan T Galvis did an excellent job installing our ducted air conditioning. They were very professional, punctual, kept our house really tidy and cleaned up after. The Allianz team and the guys did a wonderful job and were very happy
Patrick W.

Pamela C.
Excellent service - very professional - happy with the outcome - would recommend
Lucinda O.
Responsive, quick, communicative and really lovely to deal with. Will be using ACC again!
Kuan C.
We had our air con installed. From initial consultation to final installation took less than 2 weeks. Jake, Yunus, Gotham, Emre and their team has been exceptionally great. The sales consultation was thorough and easily understood. Jake was personable, personable and communicative.

Yunus's installation team was prompt, and engaging. The installation took no time at all and best of all, the place was cleaned up and spotless by the time they are done.

The air con is working fantastically. I'm super grateful. Would definitely recommend them and use them again in the future
Cosmas K.
They deployed all the resources necessary to finish a big tricky job on time. Polite and professional - thanks Tommy, Dragon and Ben
John S.
Really happy with the service done by Alliance's technicians. Very prompt, responsive and polite. They even came with boots cover to keep our place clean and tidy when they came and do our AC service and maintenance. Thanks guys!
Sarah D.
I was really happy with Alliance from start to finish. The initial communication and appointments and notifying me on approach was excellent. The two technicians were very clean and polite and conscious of not dirtying or damaging my property with their equipment or ladders. They properly advised and explained the processes and options and I’m very happy with the end result. I’ll definitely use them again.
