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.

ACC did a really great job with my difficult installation on a thick walled terrace with limitations of where piping could go. They were efficient and had the job done over 2 days, the week of booking. They were tidy, discussed placement options and what would look best and gave me a better than expected outcome. They were considerate and tidied up after themselves. I would strongly recommend.
