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.

I am very happy to support a local business, especially when they go "above and beyond" in customer service and professionalism, from Chris doing the quote, the office team handling the booking (thank you so much for bringing my job forward!), and the install team, Dragan, Cristian and Miguel, who consulted with me at every step and paid attention to the finer details, like plumbing in both discharge pipes to the downpipe a couple of metres away. Great job, thank you boys!

I have had an amazing experience from start to finish. We first met James who walked us through the different models and what was possible for our unit. James also was very efficient with the necessary paperwork required for strata approval. In regards to the installation Dzagan, Christian and Harry were amazing and did a great job with installing and cleaning up!. I also loved the fridge magnet that doubles as a bottle opener. Great experience and would recommend to anyone.

Alliance did a great job installing our AC units. They were prompt in their replies, quick in quoting, reasonably priced, and the install process was smooth.

I could not be happier with the installation of our ducted heating and cooling system, right in time for the hot summer season. All the options were clearly explained and Liam was great at providing his expert recommendations. The job was scoped and booked in quickly considering the time of year. A truly professional, courteous and efficient team did the install, thank you so much Vy, Shabi, Miguel, Benjamin, Peter and Vash. Everything was seamlessly coordinated with minimal disruption, including electrical work. Highly recommend. Thank you so much!

I recently had my old ducted air conditioning system replaced by Alliance Climate Control. It was an excellent experience from initial contact right through to installation completion, with the company's focus on quality solutions and service very apparent. I am absolutely thrilled with my new system and highly recommend Alliance Climate Control.For those interested in more detail...The original ducted air conditioning system installed when my house was built had been inoperable for a few years, had needed extensive maintenance while it was working, and never really performed satisfactorily when temperatures were outside a moderate range. The orientation of my house with respect to the summer sun, the use of specific rooms, and a fair quantity of heat-generating gear added a special twist to my requirements.Goran and Jake clearly took these requirements and my priorities fully into consideration in the solution they designed, as typical setups like the original just do not work for me. With a dual system required the cost was obviously higher than a single system so they also provided a less expensive alternative, but ultimately I decided on the premium solution as the ability to operate effectively, without restriction, on both the hottest days and coldest nights was important to me. Goran's help in finalising this was greatly appreciated.It was a three-day installation, starting in near-40-degree temperatures and ending in pouring rain, but the team worked hard to ensure the installation was completed on time.The core installation team of Andres, Ivan and Benjamin were fantastic, and were there for all three days including the whole of the final extremely long day. Other Alliance team members attended at various times throughout the installation as needed. Everyone was friendly, professional, and clearly took pride and care in their work. There were a few hurdles during the installation which the team took in stride: as the customer it definitely felt like ensuring I was happy was the priority.I was impressed with the care they took, for example when manouvering bulky equipment around my house, double-checking that things were storm-safe after the initial work in the roof, protecting nearby surfaces when cutting holes in the ceiling, meeting my super-pedantic requirements for positioning equipment... even wrangling manufacturer-faulty ceiling grilles so I would not be bothered by their out-of-alignment appearance for the few days until they were replaced. They also cleaned up thoroughly at the end of each day's work.The new systems are amazingly quiet, both inside and outside, easy to control, and very effective in the limited use they've had so far. I'm actually looking forward to a stinking hot day to truly bask in the contrast, and in the meantime am happily enjoying how much more comfortable my house is.

Very happy with the work yesterday by Dragan, Louis, JJ et al to install an air conditioner at our terrace house - and with James who prepared the quote. It was a complex job and I was impressed at how Alliance was able to swing in extra resources to get the job finished on time. They were very courteous, hard working and cleaned up well at the end of the job.

Very happy with this service! Organising the callout was super convenient, the team were very patient and explained everything very clearly. I was able to call back and easily arrange a service after double checking with other providers. Raj was really helpful during the callout, he went immediately into work and fixed my old ducted system and gave his suggestions on next actions. He answered all my questions and took care to go through the issues. He gave exact 30min call before his arrival and was done within the hour or so. I will go back to ACC for any future jobs!

Goran, Zac and Michael were super helpful and patient in answering all my questions prior to installation of a split system in my strata apartment. BJ, Kim and Anthony, the installers on the day, were fantastic, everything ran smoothly and my home was left tidy. I am very happy with Alliance and would not hesitate in recommending them.
