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.

Liam was fantastic. Very friendly, clean and job well done. Highly recommend Alliance. Always such a good service. Have used many times and will continue to. Keely also super friendly and helpful giving me eta so I wasn’t waiting.
Amith S.
The service and follow up was prompt and as promised... We had a 9 year old AC unit which had stopped cooling and making unsteady noises... The initial review and assessment to change the unit foundations which was rotting and a service was point on. The service person was prompt, very kind and mindful despite the difficult access to the roof unit. Have to say, the only issue I'd have was the initial inspector and quote pushing us to replace the unit for double the service price which in itself was a bit pricey, but in these days a full days of work it's expected. All in all an happy customer, as happy to pay a premium for a job well done! Great service - definitely will use again.
Mary
Explanation and co-operation from go to woe. Couldn't be happier 😁
Jennifer F.
Replacing old gas heating system with new heating and cooling system. I was impressed with Jake’s knowledge when he came out to quote the job, then the Installation team was very experienced and professional, good communication and provided onsite solution. I am very happy with the result, thanks to Vy, Lyn, Eric & Peter.
Eric T.
We got AC for our North Bondi house and could not be happier.
From initial conversation Aysa came up with a very genius plan for placement installation of the AC. Installation team Gokhan, Louise and Charles was so helpful and made the idea happened
They were so clean, tidy up everything and super knowledgeable. They did a schmick job.
Many thanks guys 🙏🏻
Allan L.
Happy with the work done, clean up and respect for our property by Ivan and his partner (sorry name forgotten). Follow up plaster work was also done well and Liam is to be commended.
Ugur O.
Charles and Arron did a great job installing the pendant and outdoor lights. Took great care to leave everything perfect and clean.
Simon van W.
We installed our air conditioning 5 years ago. The installation was perfect and we have had no issues in all the time we have owned the system. We had to get them back because one unit was leaking water. They were prompt to attend to the problem, admitted that some of the problem was their issue and they would cover the fix themselves.

They owned the problem. They are always very polite. The engineers they send out are highly professional, leave no mess, take off their boots and are good at communication with the client.

I've recommended them to many people..
Tam T.
We have asked Alliance Climate Control to come and service our 2 air con systems (one central and the other, a stand slone unit). Andres - a young trademan came ontime with prior warning and did a really good job for us. We also had Kyle (?) coming later to fix a condensate leakage issue which he also did well, on time with prior phone call. We then signed a 3-year maintenance contrsct with ACC after our good experience with their workers. We strongly recommend this group, having professional and friendly staff working for the company. Thank you ACC
Ian B.
We were delighted with our experience with the Alliance team of Tommy, Nick and Luan. They went about the job professionally, expertly and with no fuss. They left the job site as they found it, perfectly clean. What a wonderful example of hard working young men and a credit to your organisation. All contacts with these young men were courteous and polite. Well done Alliance.
Angus H.
Connor and Steven completed some drainage works and also a service of three of my AC units today. They were friendly, professional and communicated excellently. Highly recommend these guys!
Christopher B.
Alliance team on time and efficient. Thanks Shabi and Louis for handling both the callouts so well.
Elliott Y.
The team Kristin, Aaron P, John M, and Chris D were as good as it gets. From my initial request with Adrian, confirmation appointment with Kristin to the actual work undertaken was all a pleasure. For me as a customer I was again impressed with their expertise and their communication. There's a lot to be said about Alliance, all good!
David B.
Very happy with the product and the installation, very professional and efficient. Highly recommend.
Clemence W.
We had Shabi, Louis and Nicolas install our aircon right before the heat wave this week. They worked really hard and we love the result.
Kathryn T.
A big thank you to the whole team for a professional and very clean job, can’t thank them enough. They fixed up our ducted system and installed a new system at the back of our house! Big shout out to Andre G for managing the ducted service, and to Gokhan, Veysel, Michael and the electrician Charles for installing the new system. We will now use them for all our servicing.
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
Roger P.
Excellent service from Andre. Thank You.
Cate C.
Service technician polite and efficient
Marcus W.
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!
