Sydney’s Carbon Monoxide
Testing Experts

If you have a gas heating system, it’s important to know how to keep your home safe from carbon monoxide. As an invisible and odourless gas, carbon monoxide can’t be detected without proper carbon monoxide testing. 

A carbon monoxide leak can be deadly, which is why it’s important to have your home tested for CO levels. If you have any type of appliance that burns fuel, it’s important to have a carbon monoxide detector installed, and know who to call for regular carbon monoxide testing.

Carbon monoxide poisoning can cause serious health complications, from flu-like symptoms through to cardiac arrest. If you suspect a carbon monoxide leak, or haven’t had your gas appliances tested recently, you could be at risk. 

Here at Alliance Climate Control, we are Sydney’s carbon monoxide experts. We can test your home for CO levels and install a carbon monoxide detector if needed. 

For complete peace of mind, get in touch with Alliance Climate Control, the professional carbon monoxide testing experts.

What is Carbon Monoxide?

Carbon monoxide is a gas that’s produced by the incomplete burning of fuels such as natural gas, propane, oil, kerosene, coal or wood.

Any gas-powered appliance can produce carbon monoxide (CO) if it is not properly installed or maintained. The most common cause of carbon monoxide in the home is faulty gas appliances, such as heaters, cooktops, covens, fireplaces and hot water systems. 

In most cases, these gas appliances are perfectly safe. However, if something goes wrong, it’s critical to catch carbon monoxide build-up as quickly as possible to keep your home safe. 

Carbon monoxide build ups in your home can be incredibly hazardous to your health and should be investigated as soon as discovered.

Do All Gas Heaters Produce Carbon Monoxide?

When working properly, modern gas heaters produce a nearly negligible level of carbon monoxide and are perfectly safe in the home

However, improper maintenance and faults can cause gas appliances to leak carbon monoxide into the home, where it can be inhaled. All gas heaters have the potential to cause this problem if a fault develops, and the longer it goes undetected, the greater the risk. 

Any gas heater that is installed in your home should be tested at least annually for carbon monoxide emissions. It’s dangerous to ignore carbon monoxide tests, as this gas is odourless and invisible – and a carbon monoxide leak can be deadly before you’re even aware of it.

Because gas heaters can produce carbon monoxide, it is important to have your heating system inspected and serviced every year by a qualified technician. Here at Alliance Climate Control, we are licensed and insured to perform carbon monoxide testing on your gas heater. 

Could your gas appliances be causing carbon monoxide build-up? There’s one way to be certain – call us today to perform a carbon monoxide test.

What Causes Carbon Monoxide
In The Home?

Some of the things that can cause carbon monoxide in your home include: 

Blocked Chimneys or Flues – A blocked chimney or flue can prevent the exhaust fumes from your gas heater from escaping properly, which can cause carbon monoxide to build up in your home.

Exhaust Pipe Leaks –  A leak in the exhaust pipe can allow carbon monoxide to escape from your gas heater and enter your home. Gas heater leaks can be dangerous and should be fixed as soon as possible. A qualified technician should be called to fix any faults in your gas heater urgently. 

Cracked Heat Exchangers – A cracked heat exchanger can allow carbon monoxide to escape from your gas heater and enter your home. Similarly, a dirty or clogged heat exchanger can also cause carbon monoxide to build up in your home. If your gas heater is not properly maintained, it can produce carbon monoxide.

If you have any of these problems with your gas heater, it is important to call a qualified technician to fix them.

Carbon monoxide leaks can be deadly, so it is important to take precautions and have your gas heating inspected and serviced every year. 

Here at Alliance Climate Control, we are licensed and qualified to perform carbon monoxide testing on your gas heater. To book an appointment, contact our Sydney-based team today.

Signs You Have A
Carbon Monoxide Leak

Carbon monoxide is invisible and odourless, so it’s difficult to know if you have a carbon monoxide leak in your home. However, there are a few signs that you may have a carbon monoxide leak:

Dizziness – If you are feeling dizzy in your home, especially while your gas heater is on, it’s very possible you have a carbon monoxide leak. Carbon monoxide is odourless and colourless so it can be very difficult to detect. If multiple people in your home are feeling dizzy, exit your home and contact an expert immediately. 

Gas Heater Flame Discolouration – If the flame in your gas heater is discoloured, it could be a sign of carbon monoxide leakage. A yellow or orange flame is a sign that the fire may be mixing with the carbon monoxide in the air, and you should turn your system off, and contact a technician for urgent testing. 

Carbon Monoxide Tester Alerts – Installing a carbon monoxide tester is essential for every home with a gas heater. These machines will automatically detect carbon monoxide in the air and will alert you audibly. Carbon monoxide alarms save lives every year, and it’s always worth installing one.  

Visible Black Soot – There should not be visible black soot around your gas heater. If there is, it’s usually a sign of a bigger issue that could lead to carbon monoxide leakage. If you spot this issue, contact a gas heating technician urgently. 

Water Leaks – Water or liquid leaking from your gas heater can be a serious sign of damage. If water is able to leak from your system, so can carbon monoxide. If you notice water leaks, the safest option is to contact a local specialist. 

If you have any of these signs, it is important to call a qualified technician to inspect your gas heater ASAP. 

For the best in carbon monoxide testing in Sydney, look no further than the team at Alliance. We are licensed and insured to perform carbon monoxide testing on your gas heater, so you can be sure that it is safe to use.

What Are The Harmful Effects Of
Carbon Monoxide?

Gas Central Heater

Carbon monoxide is a potentially deadly gas that can cause serious health problems if you are exposed to it. Carbon monoxide is known to cause flu-like symptoms, such as migraines, nausea, and dizziness. It can also cause more serious health problems, such as chest pain, heart attack, and stroke.

If exposed to large amounts of carbon monoxide or exposed for long periods of time, you can experience chest pain and impaired vision. Carbon monoxide can also cause death. That’s why it’s important to have your gas heater inspected by a trained technician if you think you may have a carbon monoxide leak. It’s also essential to have a carbon monoxide detector in your home.

If you start to feel sick or dizzy when you are in your home and you have a gas heater, it may be because of the carbon monoxide in your home. If you have any of these symptoms, it is important to get out of your home and call a doctor.

A carbon monoxide test can be done quickly by a professional to see if you have any carbon monoxide in your home. The test is fast and inexpensive and can help to keep your family safe. Here at Alliance, we offer carbon monoxide testing to ensure that your gas heater is safe to use. For more information, or to book an appointment, call us today.

What Should I Do If I Have A
Carbon Monoxide Leak?

If you have a carbon monoxide leak, you should immediately turn off your gas heater and leave your home. Once it’s turned off, make sure to call a qualified gas technician to come and inspect your gas heater. 

Carbon monoxide testing is the only way to be certain whether your heating system is giving off dangerous gases. If there is a positive reading, your technician will also be able to find the source of the leak and repair it.

When your gas heater technician is repairing your gas heater, it is important to stay out of the home. The fumes from the gas heater can be dangerous, and you don’t want to breathe them in. When they fix the leak, you can ask them to test the carbon monoxide levels in your home to ensure it’s safe to return.

A gas heating specialist is also able to install or test your carbon monoxide detector to ensure that it is working properly. A carbon monoxide tester is essential for your safety and the safety of your family – so if you don’t have one, this should be your top priority.

If you need a gas heater specialist to come and take a look at your gas heater, the team at Alliance Climate Control is here to help. We are fully licensed and insured and can help you to keep your family safe if you have a carbon monoxide leak. 

If you have or suspect you have a carbon monoxide leak, call us immediately on (02) 8046 9984.

Alessandro C.
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).
Pete M.
Awesome company, awesome service. Quick reliable, very friendly and very informative.

Class act team! Love your work!

Pete Mac.
James D.
Gokhan and Louis did an amazing job installing my air conditioner! We had them install a split system in our bedroom, and couldn’t be happier

Their communication was excellent - explained the whole process and were very helpful and accommodating. The little things like helping to test different power mains to find the best configuration, the care they took to cover up and move my furniture, and the spotless cleaning job they did afterwards really set them apart. They even gave us a small gift bag at the end, which was a nice touch.

Highly recommended to go with this company, they are professionals through and through!
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!

Jason arrived on time. I was very impressed with Jason’s performance and his knowledge of the system we had. Jason explained in detail what was done to the system and suggested the best way to clean the filter when it requires cleaning.
JJ
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.
Megan B.

Charles & Mo from Alliance were great, they did a difficult installation perfectly and cleaned up afterwards as well. Will be using their services again in the future.

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!
Garry K.
We are delighted with the level of service and the quality of the job. The technicians, Mitesh and Nick were fantastic

We have already referred one of our friends to Alliance
Gary W.
Alliance has done an amazing job from providing the solution , quoting and install by Vy and his team. The install was competed in one day with an even better outcome than originally designed. Well done to the entire Alliance Team and would highly recommend.
Russell O.
ACC was thorough and professional on their quote and their installation was all completed ahead of schedule. They made an effort to minimize the mess caused by the work and their cleaned up and hauled away all packaging. The AC has made our house a home!
Maria M.
Extremely impressed with Shaby, Michael and Benjamin from Alliance. Professional AC installation work, polite and friendly and very helpful. I would highly recommend these guys and the costumer service team from Alliance .
Helena M.
From the very beginning I knew I would receive good service from this company. The lady that answered the phone ( Kayley I believe) was very efficient in assessing what I needed and organising a supervisor to come in and arrange quote. That was Alex - he was very straightforward and a very good salesman!! The service itself was also straightforward with two techs coming in (Mitiesh and Nick) and they just got on with it while dealing with a very curious pet! Overall a very positive experience and I will be signing up with them for regular maintenance and refer the company for anyone who has a similar issue that I had. Thanks
Anne B.
We were very pleased with the whole process. Thank you.
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.
Paul M.
Very proficient and easy Company to work with. Quality product and workmanship.
