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.

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.

Andy P.
Absolutely perfect service from the initial quote right through to the completion of the job! The team Liam, Goran, B.J., Meady Juan, Ivan, Maso, Will and Vash were all professionals and experts for getting everything done! Highly recommend Alliance Climate Control 🙂
isobel H.
What a pleasure to encounter a polite, professional and knowledgeable tradesman. My air conditioners were sparkling clean both inside and outside. Emre left my home in an immaculate condition. I would highly recommend this service
Clare B.
You really feel like you are in good hands with Alliance. From the quote with Will, problem solving a difficult install, to the install team with Tommy, Miguel and Gokhan, the service was fantastic. Always kept informed, not assuming what you prefer, I was always asked which is not always the case with trades people. The job was clean, professional with extra effort put in to make it tie into the house exterior neatly. So happy with the result.
Joanne
Another happy customer!
We are very grateful to Jake and James for working out a way to install three split system units without having a huge motor attached to the front of the house.
Thank you also to Tommy, Miguel and Diego for working so hard (and long) to finish on time despite the wet weather. Thank you to the electricians, plasterers and painter who were all punctual, courteous and tidy.
We are delighted with the result.
Michael B.
Wonderfully professionally executed.
The process from start to finish was without fault. It’s exactly as you advertised a fast clean well done job.
Richard K.
Emre, our technician, was awesome. Prompt. Thorough. Knowledgeable. And above all, honest. He did a cracking job and our aircon system, long overdue a service, is like new.
Janine R.
Thank you for making the experience so professional. It was not stressful at all. Staff are easy to deal with and take the time to build trust. Also will take the time to explain what is happening. I will certainly recommend them to others.

Alliance Climate Control were customer focused and excellent to deal with at every step of the process. Our installer, Adam did a great job. We are very happy with our new Daikin from alliance.
Edmund B.
I had an aircon installed in our commercial premises by Alliance yesterday. They did an excellent job - the techs (B.J., Meedy, Charles, blade and electricians Peter & Aden had a complex job installing through a very narrow roof cavity across the office. They results were very professional - and the work cleanup very thorough.
Andrew N.
Alliance were great from start to finish! Very professional service, they provided honest consultation on the ducted options we had for our property. Install team did a very fast and efficient job within one day. Would highly recommend Alliance CC!
Mike U.
Andre Stephen and Coby did a great job installing an upgraded system. Thorough, professional and helpful at every step. At no time did I feel pushed into making any decision and only chose what was right for us. Great service and installation, would highly recommend
Robynne K.
Andre was punctual, friendly, respectful & efficient. And you can’t really ask for more than that. The technicians Alliance use are always consummate professionals.
Noemi S.
I recently had the aircon in my unit upgraded from a 10+ year old ducted system to a new 16kw beast. From the first interaction with Alliance I could tell it is a professional, well oiled outfit.

The quote inspection was arranged promptly after sending my enquiry, and Liam Doyle came to inspect the apartment and make recommendations. He was very pleasant, attentive to the requirements and thorough. I appreciated his very professional interaction with me and his detailed explanation of how the system would work. He was very prompt in sending through the quote. Strata took some time to approve the implementation, and I received two follow-ups from the team in that time. Nothing pushy, I was pleased with the contact as I felt it was another indication of a good process behind the scenes. After receiving strata approval I asked Liam to come back to discuss some cosmetic changes to the internal layout and he was very obliging and once again very attentive and professional. He came over on his way home that same afternoon and had the updated quote to me two days later.

I subsequently dealt with Will Williams who was the scheduler assigned to the job. He was also very professional and gave me a run-down of the installation process, timings, and answered all my questions without hassle, and with a great attitude once again. He was able to schedule me in promptly within two weeks which was ideal for our timing.

I know its unusual to call out the accounts team, but I paid a deposit and two instalments through Eric Zhang who once again blew me away with his professionalism and prompt response. He was pleasant, efficient and cordial on the phone and issued formal receipts within minutes of payment going through.

Finally, the installation team blew me away. Our installers Garret, Shabi and Daniel H were all extremely professional and took great care to tidy up after themselves and ensure everything was left in good order over the three days they took to install. I cannot speak highly enough of the excellent job they did with the installation. Nothing was too difficult, they made a number of suggestions that added to their workload but would be more aesthetically pleasing and had absolutely no issues answering questions or making changes as the install went along. Honestly a dream crew.

Lastly, we wrapped up the installation with Harry the plasterer, and the painters whose names I didnt catch. Once again all extremely professional, pleasant individuals that I was very comfortable with, and nothing was too much trouble. Harry in particular was especially helpful, and encountered the inevitable issue of uneven concrete slabs and walls not at right angles but promptly found solutions without letting these issues cause either concern, or delays. Harry was truly excellent and did an amazing job on a relatively difficult site.

Thank you Alliance team, you should be very proud of the work you all do, I could not be happier and have been singing your praises to everyone I know. I almost wish I had more aircon to install so I can engage you again!

Thanks again for a wonderful job and a great finished product, I should probably add that the aircon also works great!
Philip H.
Good reliable service !
marie C.
Very impressed with Alliance Climate Control professionalism from their starting quote to the finished outcome in our Victorian terrace. Clear communication throughout the job. Shout out to a great Install and maintenance team, Ivan, Broody, Ahmad Qais and Emre. All outstanding nice guys. Very punctual, courteous, hard working and I much appreciated the clean up at the end of the day. Highly Recommend.
Wendy W.
Emre your technician was very thorough, explained all and made sure we were happy when he was finished. Will certainly recommend you to others
Paul L.
Alliance staff were very professional in advising my wife and I at all times what they intended to do and whether this was okay. They cleaned up after their work and provided feedback about air conditioning issues. I appreciated Mr Yim explaining to me the various features of the Daikin air conditioner controller.
Damon L.
Outstanding service! I called yesterday for a second opinion on our ducted gas heating, which had stopped working. Another company told us we needed to replace the entire Braemar unit for $6,000. Thankfully, Appliance Serviceman Gabriel took the time to properly diagnose the issue, cleaned the sensors, and had it running again — all for the cost of a very reasonable service call. His expertise, honesty, and excellent customer service truly made my day. Couldn’t be happier and highly recommend Gabriel!
Barbara L.
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.
Tristan C.
Couldn't be happier with the amazing service. Super quick turnaround (sent an email on a Monday night, by Wednesday it was sorted). Kody was super helpful and reasonable in diagnosing and quoting, then Emre tackled the pretty big job (took him hours) without complaint, and was super helpful in answering any questions we had and resolving an unexpected issue. Just top notch service and I can't imagine calling anyone else next time we need help with the AC units.
Michael J.
I was very pleased with the result. I booked a service call some weeks away, but got a call a few days later that an earlier time was available. Excellent. I took it. Kyle came on time, did the job very thoroughly. And he did not complain about parking in the area! Excellent again. I really appreciated the communication so that I knew when he was coming. I signed up for the future!
Laila
Three years on from the initial airconditioner installation and upgrading our external electrical board, I again needed Alliance to fix some old wiring inside the house and look at the air conditioner unit that had stopped working. Again, their service was great. The issues were tricky to fix, but I cannot fault their service. It was friendly, attentive and competent. Even more impressive was the follow-up of the technicians very early the next morning to make sure the air conditioner problem was fixed - and when it wasn't, they were straight back. Thank you to all who attended over those few weeks, including - Vishal, Andre, Christian, Peter, Steve, and young Andre. It's not yet fully resolved, but it's now a warranty issue with Actron - here's hoping they live up to the service standards of their dealer. Thank you Alliance.
avinesh N.
Good team of workers who care
Linley M.
Big thanks to Alex who did the initial quote and then Jason and Nik who came and completed the job. Company was efficient from the time of online enquiry through to quote and then servicing. Air con was well overdue for a service and is now working far better than before. Thanks team!
