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.

Chris and the team took on a niche home networking job for me to cable up 12 runs across 5 rooms.

From the start I was consulted with on different options, fantastic communication throughout and an absolutely stellar end result. Massive thank you to Chris who was present throughout and handled the job with ease, though I know it wasn't simple. Thanks again team!read more
