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.

What Our Community
Is Saying About Alliance

Based on 2400 reviews
Sue H.
We were very impressed with all aspects of the installation and replacement of our outdated ducted air conditioning system. The prompt response we got from Jake, who came out to scope the job & provide a quote was very impressive. As was the turnaround from accepting the quote to the installation (3 days). The team who carried out the installation, were terrific & worked tirelessly to get the job done with minimum disruption, which we appreciated as it was a fairly complicated job. We would like to thank each of them, Jonathan, Miguel, Matt, Maisam & Ahmad, they all deserve a shout out. All in all from start to finish it was a great experience & couldn't recommend Alliance highly enough.
Steven K.
Lachlan was professional,punctual and pleasant to deal with

Job well done, Jason was very clear in the process before hand and also explained everything well when finished.
Neil L.
Update: 3 Dec

Decided to ask ACC to do some straight electrical - powerpoint installs , sconce replacement.

JJ and Aden did a great job: quick, friendly, informative. Really neat job. Cleaned up after themselves and even took the old sconces for disposal.

Happy with the work.

JJ also noticed some switches were out of code in my switchboard and recommended and completed replacements.

So house electrics are a little safer too.

AIR COND INSTALL Review:

Two teams worked on our place:

Andres , Cristian and Qais replaced our ducted system, and Vy, Luan and Maison installed a separate split system where ducted couldn't reach.

Both teams did an excellent job.

Everyone arrived on time, walked us through what was going to be done and were happy to answer any questions. They were friendly and professional. Completed install on time, showed us how the new system worked and made sure we were happy. Cleaned up afterwards too - as promised.

Ducted team worked for two days in some hot conditions, removed old unit and ducting and disposed off. Hassle free for us. Install of new system, ducting and control system was trouble free for us.

Split team did a great job too - gave advice on best position for indoor and outdoor unit, clean efficient install, tidied up after themselves. Really professional.

Great from start to finish.
M E.
Tech was nice polite guy but he did not have the correct filters and wanted to cut some down to fit .. this does not work as cut down filters do not hold their shape so I told the guy not to replace them this time although the cut downs ones that were installed last year were quite clean, they were not in good shape.
Update: the company apologised for not having the correct filters at the time and promptly arranged for the correct units to be installed .. they really do follow up and fix any issue so deserve 5 Stars
Alex K.
Alliance are the best! Garret, Shane and Louis did a fantastic job installing our new AC unit. Protective mats were placed on all floors, they removed all mess and even took away our old unit. Garret ensured we were across the installation process, asked questions when required and also informed us of how to operate the new system. Great job!
Elaine B.
Excellent and professional service from start to finish. Particularly impressed with the team who did the installation. Efficient and careful. Attention to achieving optimum performance from the system much appreciated.
Karen P.
Jake and James were efficient, punctual, clean and courteous. My AC unit is as good as new. I would have no hesitation in recommending Jake and James and I will certainly use Alliance in the future. Thank you guys.
Maria C.
We had our split system air-conditioning installed almost two years ago now (April 2024) and I have been meaning to write a review, because we were really happy with the service and installation, and I have only just got around to it. But that may be good, as I can say that the system works perfectly, and we have had not problems.

We have an inner city terrace, and have over more than a decade got quotes, only to be told that "it is not possible". So, I looked for someone close, who I figured would have experience with our type of dwelling. The quote was very reasonable, the installation went smoothly, and we are very happy.
Tracey H.
Very good service from BJ, James, Errol and Will for our air conditioner installation. Errol and Will were very responsive and flexible during the consultation and booking phases - I felt like their advice was solid and really suited my circumstances. BJ and James were an incredibly professional and efficient installation team - they got it done, cleaned up, and made sure I was across our new aircon. Would recommend.
Kylie B.
Excellent service - on time, friendly and professionally completed the job ( air conditioning & two ceiling fans). Also cleaned up and put furniture back into position.

Thank you to the team who did the work - Shabi, Louis, Peter & JJ.
Also to Will behind the scenes who coordinated the scheduling of this job ( fans added in )
Thanks again

Vanessa S.
The team have just left after installing 2 split systems so this is a very early review, but very happy with the service so far. Errol initially gave a quote and took the time to go through several budget and design options and explain everything in detail, he was great! Installation happened very fast, booked in a week after acceptance of quote. BJ and James were here today and did an amazing job, being sensitive to the fact I had a full day of meetings trying to work from home, consulting with me around this. A lot of furniture and equipment had to be moved to facilitate access and they even went to the extent of moving things back to the exact place they had been, even plugging other electrical equipment back in and vaccuuming. They explained the workings with me afterwards and how to maintain, and left the place spotless. The air con is working perfectly at the moment, completely as described. Also would like to call out Eric who did some behind the scenes work. Great service all round so far! Would recommend highly!
Kamen C.
I had a very good experience. The service was efficient, and the staff were friendly and helpful throughout. Thank you for your support.

Wonderful workers. Efficient, polite & hard working
Vicki B.
I am so impressed by Damon from Alliance Climate Control who has just finished servicing my 3 air conditioners. He was efficient and polite and was very willing to answer my questions and his answers gave me confidence that he knew what he was doing. So impressed I’ve signed up for a 3 year maintenance plan. I highly recommend this bright young man and the company itself that presents as very professional.
Leesa E.
VY - Luaw- Miguel were amazing! Great professionals.. thanks Team! The outdoor installation and in room look great!
Patricia G.
Excelente work very profesional. Highly recommended.
Alexey B.
Amazing maintenance service one year after the installation. The technician arrived on time, on the dot effectively, and spent 2 full hours cleaning filters and aircon unit bodies, checking everything etc. The units and filters were in a good condition, but this demonstrates the thoroughness of the service.
