What Are The Benefits Of
Regular Gas Heater Servicing?

A gas heating system is something you rely on to keep your home warm, and it’s important to keep it in good working order. Regularly having your ducted heating serviced helps avoid costly repairs, keeping it running safely and efficiently. 

Benefits of regular gas heater servicing include:

Cheaper operating costs – A well-maintained gas heating system will run more efficiently, saving you money on your energy bill.

Better heating performance – A regularly serviced system will heat your home more evenly, offering faster and more efficient climate control.

Fewer repairs – A well-serviced system is less likely to break down, while skipping gas heating maintenance can lead to premature wear and tear.

Cleaner air circulation – A properly serviced system will help to circulate clean air throughout your home, improving your indoor air quality.

Helps prevent carbon monoxide poisoning – Carbon monoxide is a deadly gas that can be produced by faulty or poorly maintained gas heating systems. By having your gas heater serviced regularly, you can help prevent carbon monoxide poisoning in your home.

Protects your warranty – Some manufacturers require proof of regular servicing to validate the warranty. Regularly scheduled servicing will help protect and validate that warranty if you need it later down the track.

Having your ducted heating serviced is an essential investment in your home’s safety and energy-efficiency. To book your next service, contact the experts at Alliance Climate Control.

How Often Should You Service
Your Gas Heater?

Keeping gas central heating in good working order is important for a number of reasons, ensuring your heating system is reliable, safe and long-lasting. But how do you know when your gas heater needs servicing? 

The average gas heating system needs to be serviced every 12 months, but this may vary depending on the make and model of your heater, as well as how often it’s used. For example, if you’re using your gas heater for over 7 hours a day, it’s going to need more frequent servicing to avoid performance decline. 

If you’re not sure when your gas heater was last serviced, or if it needs servicing, don’t put it off any longer. Here at Alliance Climate Control, we’re Sydney’s experts in gas heating. We’re here to help you keep your home’s heating working efficiently, saving you dollars on your gas bills.  

Here at Alliance, we understand that keeping your home warm and comfortable is important. Keeping our clients’ gas systems in safe working order is our top priority. 

If it’s time for gas heating maintenance, book an appointment with our technicians today. 

What’s Involved in a
Ducted Gas Heating Service?

When the team at Alliance Climate Control comes to your home, we start every heating maintenance service with a thorough inspection. We’ll make sure that all components are in good working order, and look for any hidden signs of wear or damage. 

Ducted gas heater servicing includes: 

Carbon Monoxide Testing – We use specialised equipment to test your home for any carbon monoxide leaks. Our carbon monoxide testing equipment is incredibly accurate ensuring any dangerous leaks can be dealt with immediately. 

Fan Assembly Cleaning – Fan assembly systems can build up dust and debris which can lead to reduced efficiency and higher wear and tear. A clean fan assembly is essential to prolonging the life of your ducted heating. 

Flame Sensor Testing – The flame sensor is an essential part of your gas heating system. As part of our gas heating service, we clean and test flame sensors. 

Igniter Adjusting – Keeping the igniter in working order is required for any gas heating system. As part of our maintenance, we check the spark gaps in your igniter and test them to ensure they are working correctly. 

Capacitor Checking – We will inspect the capacitors in your system and compare it to the output in your home to make sure everything is running at a safe and efficient voltage. 

Airflow Inspections – Airflow is essential no matter what type of heating system you have. As part of our service, we inspect ductwork to ensure there are no blockages or faults impacting efficiency. 

Return Air Filtration & Grille Examining – The return air filters and grilles are another component that can get dirty and clogged over time which will reduce air flow and efficiency. We also treat these parts to prevent bacteria build-up. 

Voltage Testing – We use voltage testing units to ensure your gas heating unit that they are not overdrawing power. We can also test to see if an older system is drawing an unusual amount of power. 

Mounting Inspections – We check the mounting level of your heat exchanger to ensure it’s properly and safely installed. 

Thermostat Calibration – Thermostats can be incorrectly calibrated due to ageing, upgrades or renovations. We recalibrate thermostats as part of our service to make sure they are working efficiently. 

Flue Connection Inspections – We test the flue connections throughout your home during a service. This is part of the system that will remove harmful gases out of your home, so is critical to maintain. 

Electrical Connection Checking – We will go through and test the electrical connections in your system to ensure they are all safe and working correctly. Addressing wear and tear prevents wiring-related electrical fires. 

Carbon Monoxide Alarm Testing – Having a carbon monoxide alarm in your home is essential to your home safety. We provide carbon monoxide alarm installations, as well as regular testing. 

After the service is complete, we’ll give you a full system report of what we found and what was done during the service. This maintenance tune-up report is one of the many things that makes Alliance Climate Control unique, giving you a thorough servicing record and keeping you in the loop every step of the way. 

If there is any need for a part to be replaced, we’ll always give you a cost estimate and keep you fully informed of your options. If more extensive gas heating repairs are required, our technician will give you an honest and competitive quote on any work recommended. 

During the service, our friendly team members are more than happy to walk you through what we are doing, and give you advice on how to run your central heating more efficiently. We’ll gladly address any questions you have during the appointment. 

Here at Alliance Climate Control, we provide a comprehensive heating service and tune-up, giving you complete peace of mind. When you choose Alliance, our expert technicians will help your system run smoothly all winter long.

Why Choose Alliance for Ducted Heating
Servicing in Sydney?

Alliance Climate Control are the trusted experts in gas heating in Sydney. All of our team are licensed and qualified, with years of experience performing quality servicing and repairs. But not every technician is familiar with all models and brands, and not all have the same level of expertise. 

As a result, choosing the right gas heating professional is crucial. Poor quality gas servicing is a common cause of costly repairs and replacements later down the track. 

Small issues can be missed by an inexperienced gas heating technician, and these can cause huge issues if overlooked. Some of these issues can include:

Faulty thermostats – A faulty thermostat can cause your gas heater to turn off and on frequently, leading to more expensive energy bills.

Damaged heat exchangers – A damaged heat exchanger can lead to carbon monoxide leaks, putting your family’s safety at risk. As this usually occurs between services, it can also hide small leaks which are very dangerous without any visible signs.

Clogged venting ducts – If the venting ducts throughout a house get clogged up with dirt, waste or other debris (such as particles from smoking) then the overall efficiency of your heating system decreases considerably.

Having your system serviced by a reliable technician is the only way to ensure you won’t suffer from any of these issues. Because poorly serviced gas systems can be dangerous, you need to work with a technician you can count on to keep your family safe. 

That’s why so many families turn to Alliance Climate Control for gas heating servicing in Sydney. We’re the trusted name across Greater Sydney, and we provide a high-quality service at accessible prices. 

Don’t risk using any other company – give Alliance a call today to book your next gas heating service and tune-up.

Our Gas Heating
Maintenance Services

Alliance provides excellent services and a honest company. Jason is the best tradesman I ever see. He is very professional and friendly. He explain the issues and solutions very clearly. I certainly recommend Alliance and particularly Jason to anyone need aircon repair and service.
They are rare example of service companies should be.

We had a new aircon unit installed by Gokhan and Louis from the Alliance Team. They arrived on time, clearly explained what needed to be done, the installation was high quality and they cleaned up before they left. Highly recommend.

Excellent job today.

We couldn’t be happier with the outstanding service from Alliance Climate Control! The team delivered a truly seamless installation of four split systems at our home (Service Ref. #101598) from start to finish.

A special commendation goes to Ahmad Maisam and Meedy for their exceptional leadership, organisation, and genuine care in addressing our needs. Their professionalism, clear communication, and attention to detail made the entire process smooth and stress-free.

The workmanship was excellent, the team was punctual and respectful of our home, and everything was left spotless at the end. Simply put—the best team ever. Highly recommended to anyone looking for top-tier air conditioning service!
Lina F.
Excellent service from start to finish..after contacting 2 prior air conditioner companies weren’t interested in doing the job , I found Alliance recommended by my friend Vicki .. highly recommend
Craig L.
We were very happy with the work undertaken by Dylan last week. He was very courteous and professional. He answered our questions very clearly and investigated the 2 issues we raised very thoroughly.
Laura
The team who attended my home last week to install a split system were impeccable - Gokhan, Louis and Rodrigo - as was Errol who attended to provide the initial quote and the office team when I called with some questions pre-installation. Everyone was helpful and professional. They set high expectations and delivered!
Christian B.
Andres from Alliance was excellent, professional and very clear. Our units are now operating perfectly and he detected a major issue and presented multiple solutions. Would recommend the service highly.
Sky S.
I couldn't be happier with the excellent service and clean provided by Emre.
He was punctual, thorough with his assessment of my aircon units and managed to identify the source of why my aircon has a mouldy smell. He was professional, knowledgeable and clear with his explanation of what can be the problems as well as recommending appropriate options to address the problems.
5/5 will call upon his services again if my aircons ever give me grief (though I doubt it with the level of servicing he performed).
Nikki M.
I had a great experience from the first time I called with my initial enquiry until the completion of my installation. Excellent communication, customer care and follow up communications. I felt that I was being looked after throughout the entire experience. All of the technicians and tradesmen were very kind and extremely professional. I was kept updated throughout the installation. My place was left clean and tidy. I highly recommend this company - thanks!
Ana N.
Ivan, Brody, Miguel, B.J, Theo and Tim were amazing they kept everything clean and even without a lift they carried everything up and down. They finished in record time and I couldn't ask for a better team!

Emre was allocated to help with the aircon service for my apartment. I was very impressed with his professionalism. He is one of few dedicated technicians I have come across as knowledgeable who explained everything in details, patient with my questions, friendly, polite and on the whole, he did an amazing job. A very happy client. Thanks, Emre! Highly recommended!
Matthew K.
One of the few vendors who did an on-site inspection before install and took into account my requirements. Gokhan, Louis and Nicholas did a great job with an installation of a split system to an upstairs bedroom. Routed relatively well to avoid outside challenges. Left everything nice and clean afterwards.
Emma W.
Thank you Tommy, Kim and James for your professional courteous service this week. Very efficient and neat work. Explained options well and provided the best solutions for our awkward house.

Update - latest review for the Electrical Safety Inspection on 29/12/25 and Electrical Work on 07/01/26.

We are very impressed with Joshua, Vash and Mohammed. So, we are giving each one of them 5 stars.  Joshua was very detailed and very systematic when he conducted the safety inspection last 29/12/25. Also, giving us practical tips about safety and to monitor the old power points. He also patiently explained the importance of getting the electrical system and smoke alarm up to code and all the things that needs to be replaced. He is also courteous in his behaviour and how he engages with us.

Vash and Mohammed arrived early for the electrical work on 07/01/26.  These young blokes are very thorough, they know what they're doing. They worked as a team and non-stop for several hours. They are also impressive, respectful, and polite. Before they left, they double checked everything and even vacuumed the dining chairs and floor to keep thing tidy. We learned a lot from them and how to use electrical extensions safely.

These young men ( Joshua, Mohammed and Vash )will go far. They arrived neat, clean looking and ready to do the job. They have a high standard in workmanship, dedication and most importantly they have the right attitude about their work and how they treat us.

Kindly let them know that even though they might think they just did the electrical work. For us, they did more than that, they contributed to our health and safety.

Please, don’t stop inspiring these young men to continue developing their trade. They are the kind of professionals that our society needs. Thank you. Jennifer from Macquarie Fields.

Updated my review to include our recent service experience October 11, 2025 with Gabriel.

I want to share our recent experience with Gabriel, who provided a complete tune-up and service on our Fujitsu multi system last October 11, 2025. Overall, our experience was outstanding. My husband and I truly appreciate Gabriel’s dedication—his professionalism, expertise, and meticulous care stood out throughout the visit. He walked us through the air-conditioning health report, clearly explaining the tasks he completed and the performance of our air conditioner, while also offering practical and easy-to-follow maintenance suggestions that put our minds at ease.

Gabriel consistently demonstrates professionalism and a positive attitude toward his work, just as he did in January 2022. His respectful and polite manner made the entire process enjoyable. Thanks to Gabriel’s thorough service, we feel much more at ease knowing our air conditioner is in top condition and our home’s air quality is supporting a healthy lifestyle.

We are happy to recommend Gabriel to others, and we hope to see him again in another year or so. Thank you once again for your excellent service—Gabriel is truly deserving of 5 stars. Thank you, Gabriel.
----------------------------------------------
On the 19th of Jan 2022 an inspection was conducted by Gabriel. He was punctual and did a thorough inspection. He came back with Bailey for the AC cleaning and tune up on the 21st of Jan as per agreement. We have rated both of them 5 stars for the following reasons and base on our observations. Punctuality, tidy in appearance and work, very knowledgable with their trade, well mannered, they did a meticulous job in servicing our AC. Most of all, they were both efficient because they worked as a team. We are a very happy customer. Thank you Gabriel and Bailey.
Googie W.
The boys were so helpful, nothing was a trouble & they knew their stuff, very professional which made a great experience all round!

Karim M.
Charles and Aaron arrived on time and were patient and professional while answering all of my questions. They provided clear, written quotes, explained exactly what was included and what wasn’t, and even suggested and implemented a solution on the same day for a problem that wasnt even part of the job they initially came out to do.
William B.
Service Technician arrived within the advised block time. He carried out the required service very efficiently and provided a written report of the condition of all aspects of the A/C and cleaned all the filters, unit cover and the outdoor unit. Very satisfied with a thoroughly professional performance.
C W.
Had new AC units installed and an old one replaced. My experience with ACC and their team was fantastic from start to finish. The team that supported us included Liam, Vash, Will, B.J, Theo and Jun. Cannot thank them enough for being such a pleasure to work with. They were incredibly professional, good at what they do and showed great care in helping us with our installations. I would highly recommend ACC and this team! Thank you to the Team again!
