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.

Elle Jay Q.
We didn't go ahead with the quote, only because another company fitted our needs more closely, but I would still 100% recommend including Alliance as part of who you call when looking for aircon. Liam Doyle quoted us and he was very knowledgeable and friendly. I would definitely advise calling them if you need aircon.
Darby J.
From start to end excellent professional team, great communication, very well organised and coordinated, installation teamwork was superb, clean up was very well done.
James, Tommy, Matt, Miguel and Harry were all excellent, courteous and respectful of working in our house.
Overall they were a team that I would have back again and recommend to any future customers.
andre M.
Did what they said they would do very efficiently
Jennifer H.
The team were punctual, extremely polite and did a great job!
James H.
Andres, Ivan and Juan from Alliance Climate Control replaced two old air conditioners efficiently and timely. They were friendly and knowledgeable about the products and I highly recommend them.
Helen R.
It was raining heavily the day the Alliance Climate Control technician came to my house to provide a maintenance and check up for my two air conditioners. He carried out the job, working both inside and outside without complaint (about the rain). He was on time and efficient. I have confidence that he did an excellent job. Thank you.
Jay K
Dragon and his two mates were very polite and respectful, they drilled the wall from both sides to minimize the chipping, installed everything nicely, and completed the job on time. I am really pleased with them.
John M.
Good job.
Aaron J.
Wow! I called Alliance Climate Control to get some advice on my ageing air-conditioniers and from that moment on, it was a pleasure to deal with such a customer focused company. After emails / texts from Head Office explaining the process, Raj turned up to give me a diagnostic report on my almost broken air-conditioning system. After explaining all of the possible scenarios, I decided to purchase a new system. Team Leader Vy and Cristian turned up a couple of days later and from that point on, it was all systems go. Everything was explained simply and professionally as the process went along. Other technicians turned up ( Harry, James and Moller) to help with the installation (which at some points was more difficult than expected due to my ageing terrace house) and it was all carried out in an expert manner.
I would highly recommend Alliance Climate Control for any air-conditioning needs.
spencer B.
Great team very professional
Levi's D.
Kyle was very professional and courteous.
Kim
Alliance installed a Daikin 15.5Kw ducted unit one week ago. The team of Garrett, Lewis and Qais worked really well together. Qais was particularly impressive with his work ethics.
Also, Harry who did the plastering, and Yiannis who finished the job off with very careful painting of our ceiling.
Peter K.
Our old ducted air conditioner failed, so we contacted the team at Alliance for a replacement. They provided a competitive quote and completed the installation quickly. James Greene thoroughly explained the process and presented us with several options. Alliance offers exceptional before-and-after sales service, and we have enjoyed trouble-free air conditioning for the past two summers.
Michael W.
Tommy, Miguel and Nick did an excellent installation. Very tidy and neat.
Andrew L.
Alliance were outstanding from start to finish. Made an initial enquiry and James came out the next day. Comprehensive quote on the spot. Accepted and the whole install was done the following week - ducted system and two split systems. Install team of Yunus, Gokhan and Emre were outstanding - courteous, clean and knowledgeable - and worked hard. I'm a pedantic customer - and part of the house is very old - they were more than happy to be accomodating and sort any issues I raised. Very pleased with the quality of the work and the team - would highly recommend.
Rod W.
I needed to replace a reverse cycle central air-conditioning system that was about 20 years old and add a smaller new system in a different part of the house. I decided to use Alliance Climate Control after doing some research meeting their salesperson at my home in a very productive exchange.
Gerald B.
Special thanks to Tommy, Nick and Miguel for their excellent work
jessie R.
This was my second aircon clean and service from Alliance. Both times the techs were on time, pleasant, and knowledgeable. I wouldn't now use anyone else.
Peter H.
What a pleasant and professional service Alliance Climate Control provided. From the initial phone contact to the friendly, courteous, and efficient service provided. Alex arrived on time checked both units and kept me informed at all timers as to the best solutions. We then had BJ, Daniel and Brandon install a new Daikin unit. As mentioned when it was booked they covered furniture and did a clean install. Zac also deserves a mention as coordinating and ensuring a smooth operation made it seamless. Thank you Alliance Climate Control for making it an professional experience, highly recommend.
Scott K.
The Alliance Climate Control team, from engagement, quotation, installation and customer support was excellent. The ACC install team of Tom, Nick, Miguel, Matt, Benjamin and JJ were very professional in all aspects of the install and commissioning. Would most highly recommend ACC.
Inti R.
Tommy and Nick were absolute legends, they did an aircon relocation from my living room to my attic. both Tommy and Nick did the job with no fuzz, fast efficient and more importantly quietly. I was working from home through the job, and they needed little to nothing from me once they were setup and ready to go. The aircon was moved professionally. Thank you!
karen S.
Great service. Very professional. Highly recommend.
Mary J.
BJ,Daniel, Brandon Aysa, Zac Peter & Aden.
From the first phone call thru to quote job & clean up to showing me the easy to use remote. Have all been wonderful, professional installation fantastic & very thorough with prep, covering furniture and clean up afterwards.
This was a very considered purchase.
I'm so happy I chose to go with Alliance.
Philip M.
BJ, Daniel, Brandon, Chris Divis & Zac were all very professional the service we received was excellent. Highly recommend them. Good Job All Round.
Maurice N.
Outstanding staff. Punctual, clean, knowledgeable and efficient.
chi-kan W.
Your installation has been mostly excellent but very recently I noticed that the condensation has not been flowing into the evaporation tray. There is a short horizontal section of the pipe for discharging the water into the tray but the water, instead of dripping into the tray, tracks backwards and drips onto the floor. I have remedied this by attaching a plastic cone to that short horizontal section. In the future, ensure that the last short section of the pipe SLOPES into the tray to ensure that water doesn't track backwards.
Lia
A big job completed with ease and professionalism by ACC, so happy my place is now cool! From James Greene’s initial quote to the install team of BJ, Daniel, Brandon, JJ, Vash, Blade and Giannis, plus Zac and Eric and Will and Joe behind the scenes, everyone has been delightful to deal with. Highly recommend
Gennaro S.
Professional Team , efficient and very pleasant to deal with . Wonderful service by Tommy ,
Nick and Chris , Vash and Blade .
Brett D.
We have a two level house with 5 bedrooms 3 bathrooms lounge room family room and kitchen
We needed a system to do the whole house
I had two quotes both of which the gentlemen giving the quote were at my house for no more than 30mins.
Darko from Alliance came and was totally professional and inspected the house roof cavity and all. He then sat down with me and discussed the system that would best suited, he explained the installation process and how Alliance worked in all he was here for over 2 hours. It is because of Darko knowledge and commitment we decided to go with Alliance.
The installers arrived on time being Matt,Aaron,Mahalo and Andre. They worked here for 3 days putting in the system. We were totally impressed with the way they worked and the quality they delivered. They were also courteous, respectful and ensured they cleaned up after every day work. TRUE TRADESMEN

WE could not rate the people we have dealt with from Alliance Climate control, highly enough. From the time of quotation to the time of installation we were constantly informed of what was going on.

So from us its a 5 out of 5 for everyone involved from Alliance Climate Control in giving us a great Air Conditioned house
Sam D.
Great service options and very detailed work. Highly recommend
