Why Is My Ducted Gas Heating
Not Working?

Ducted gas heaters are a great way to efficiently heat your home in cold weather. They’re cost-effective and energy-efficient when in proper working condition, but faults can quickly compromise these benefits if they aren’t resolved. 

Your ducted gas heating system is subject to a lot of wear and tear throughout the year. Even if you’re keeping up with gas heating maintenance, there are certain things that can go wrong over time.

The most common ducted heating problems we see include:

  • Ducted heating not turning on
  • Heater blowing cold air 
  • Heater is noisy when running 
  • Poor ducted heating performance
  • Can’t program the thermostat 
  • Heating unit keeps cycling off
  • Pilot light problems 

Ducted gas heater issues can be caused by:

  • General wear and tear
  • Poor installation
  • Faulty parts
  • Weather damage
  • Lack of regular maintenance

If your ducted gas system isn’t heating a room properly, or it’s not working at all, your system may be in need of repairs. It’s important not to overlook gas heater issues, since putting it off can lead to full breakdowns or dangerous carbon monoxide leaks. 

Having trouble with your ducted heating?  Alliance Climate Control are the professionals you need for all your gas heating needs. We are one of the leading names in gas heating repairs in Sydney, and we’re trusted by thousands of local customers every year.

Signs Your Gas Heater Needs
To Be Repaired

If you’re noticing that your gas heater is not working as well as it used to, or if it’s completely stopped running, you’ve got an issue that needs to be repaired urgently. Gas heater repairs can be necessary if your system is overworked, or it hasn’t been serviced in a while. Some signs that your gas heater needs repairs include:

  1. Strange noises from your heater

    – This could be a sign that there is something wrong with the fan, the motor, or the compressor. These problems need to be repaired before your central heating is safe to use.

  2. Poor heating performance

    – If your home is slow to heat or certain areas cool too fast, there may be a fault with your gas heating unit. This could be a result of a clogged air filter, a broken heating element, or a problem with the thermostat. Repairing these problems can restore full performance to your heater.

  3. Gas heater is not turning on at all

    – This is an obvious issue that requires a licensed technician to repair. This could be a result of a broken fuse, a tripped circuit breaker, or a problem with the wiring.

  4. Increased energy bills

    – If you’ve been noticing that your gas bills are higher, it could be a sign that there is something wrong with your gas heater. Contacting a specialist like Alliance Climate Control can help identify the issue, saving you money in the long term.

  5. Poor indoor air quality

    – Noticeable change in air quality or respiratory symptoms can indicate a dangerous fault with your central heating. If your indoor air is stuffy or smells bad, a professional needs to address this urgently.

  6. Pilot light is going out

    – If you’re seeing that the pilot light on your gas heater is going out, it’s a sign that there is something wrong. This can be an urgent problem if the system is still pumping gas into your home, so needs fixing ASAP.
Ignoring gas heating problems can lead to safety hazards, and may mean the entire heating unit needs to be replaced further down the road. If you’re not sure whether you should be worried, it’s best to contact your local ducted heating specialist for an expert opinion.  Here at Alliance Climate Control, we understand that there are a variety of factors that can affect the performance of your gas heater. That’s why we perform thorough inspections to identify the cause of broken gas heating.  Our technicians come prepared to carry out a wide range of central heating repairs on the spot. For more complex problems, we can provide a full quote upfront and order any necessary parts at affordable prices.  If you’ve noticed signs of trouble, don’t wait – call the experts at Alliance Climate Control today.

Emergency Gas Heating
Repairs Sydney

While gas heaters are safe to use in your home, any faults can quickly lead to an emergency scenario. If your gas heating unit is damaged or not working properly, it can lead to a number of dangerous problems.

How Long Should A
Ducted Gas Heater Last?

Most ducted gas heating units should last between ten and fifteen years, but there are some factors that can affect this. How often the heater is used, how well it’s maintained and the quality of the model all play a part in your system’s lifespan. 

Regular maintenance is the best way to prolong the lifespan of your central heating. This includes annual ducted heating servicing, as well as acting quickly on any faults or issues you notice.

Ignoring necessary gas heater repairs can lead to decreased efficiency, shortened lifespan and even dangerous situations. Ensuring that all gas heater repairs are performed when necessary will help keep your system running smoothly, as well as extending its life.  

Prioritising ducted gas heater repairs can save you money in the long run, as a well-maintained system will be more efficient and last longer. You’ll have peace of mind knowing that your family is safe and comfortable during cold winter months, and you’ll avoid high energy bills that can result if faults aren’t repaired.

We had 2 teams at our house.
B.J,Theo and James installed units in 2 bedrooms upstairs and an inverter outside. They did a great job and had it done in one day.
We also had 2 other unots serviced and cleaned by TK and Eric who were thorough and gave us maintenance tips. The quote from Kody was spot-on and heaps betyer than the main competitor.

Original Review:
I had a split air con unit installed in my apartment by Alliance last week. Yunun and his team did a fantastic job from start to finish. They were friendly, professional and ensured that the unit, compressor, cabling and ducting was installed neatly and blended in with the surroundings. They left my apartment in showroom condition after they finished! I couldn't be happier. Highly recommended.

Update – April 2026:
Andre G came out to complete the annual maintenance on my aircon under job #105771, which Alliance installed last year. The unit was particularly dusty inside, and Andre carried out a thorough service and deep clean. He was professional, meticulous, and explained each step clearly in advance. He did a terrific job and left the apartment spotlessly clean. Thanks again to the Alliance team for consistently great service.
Nina F.
The technicians were on time and professional, they did a really good job deep cleaning our AC units which were very dirty and blocked by molds causing water dripping. I am happy that my ACs was fixed and working well now.
Jacinda M.
2026 - Kyle and Nikola came for my yearly service. They were a pleasure to have. Very professional and did such a good job! I wish I could give them 20/10 stars

Great experience! All the staff are extremely professional. It’s obvious the company has invested a lot into tech and their process to give a great customer experience. Special mention to Gabriel, BJ and Zac for their help!
JJ F.
Very good experience with Alliance Climate Control.

Ivan led the team with Mosa, Zac and electrician Mohamed. Two split units installed and condenser placed neatly at the back.

Process was smooth from start to finish. Clear quote, easy scheduling, no surprises. They arrived at 7:15am and finished by 3pm.

Old heritage terrace, not an easy job. They adapted on site and improved a couple of original decisions. Final result is better because of that.

Workmanship is clean. Conduits through the roof cavity are tidy, indoor units fit well above the windows, and the outdoor unit is discreet.

Ivan communicated clearly throughout and set everything up on our phones at the end.

Professional team. Good execution. Would highly recommend.
stefan W.
Alliance is an amazing company. I thought professional service like this had disappeared years ago. Not only that - but all team members really know their stuff. From the initial sales call with James to comms with the office, booking the day doing the install and cleaning up afterwards everything went like a training movie. How do you get everyone on the same page??? All I can say guys is thank you for an outstanding job - I'd hate to be your opposition.
Joey L.
I had the team from Alliance (Aysa, Vi, Nikola, Eric, Harry, Aiden and James) put in aircon at my apartment. The whole process was great from start to finish. They were professional, punctual, tidy and very friendly. Highly recommend!
Lachlan
The team at Alliance is excellent.

Their knowledge and service lead to an install that was a day shorter and significantly cheaper than quoted. This was completely unexpected after another local company couldn't be bothered to tell me my project was beyond their skill level and ghosted me without providing a quote.

Jason was able to avoid cutting into our ceiling which was amazing after preparing ourselves for a significant patch and paint job.

They are professional, fast and everyone I had contact with was eager to help.

If anyone even slightly mentions air con or an aircon issue I'll be recommending Alliance.
David H.
Alliance Climate Control were a pleasure to deal with. Really professional & a smooth experience from start to finish. I was really happy with the installation team - Qais, Louis & Callum did a fantastic, neat job & left the place immaculate. I asked for a minor change to the drain lines and they were very accommodating.
Stephen K.
Excellent professional service.
Turned up on time, knowledgeable technicians.
Lily L.
We recently had a new ducted air conditioning system installed by Alliance Climate Control and couldn’t be happier with the experience. Liam was the first to attend our home when our 20-year-old system failed. He took the time to thoroughly assess the situation, explain our options clearly, and provide a very competitive quote. His friendly and professional approach made the whole process easy and stress-free from the start. On installation day, Vy and his team were great. They were punctual, efficient, and kept us informed throughout the entire process. They took care to keep our home clean and made sure everything was working perfectly before they left. Overall, the service was outstanding from start to finish. We really appreciated the professionalism, clear communication, and attention to detail. Highly recommend Alliance Climate Control to anyone looking for a reliable and high-quality air conditioning installation.
Leo N.
Fantastic team and great work on replacement system install. 👍 Huge thank you to Qais, Louis & Christian.
Guy M.
Great all-round service from Alliance! Communication was timely from Will and Chris in the office, and Liam, BJ, Theo and Nic were great to deal with for the job quote, service, and install. The install required access to my neighbour’s property, he also commented that they were incredibly polite—asking to move pots and putting everything back exactly as it was. Highly recommend!
Lance L.
Good, professional installation, very happy.
Innes P.
As usual, a pleasure to work with the team, installation went well with the team completing the work in the time they said they would, and following up when needed.

All very tidy too, with everything, even the old fans taken away - great work, thanks Charles and team!
Ovi D.
Professional service, arrived on time and good communication throughout the appointment process
David B.
Excellent and efficient service.
Good humoured in spite of having to climb stairs because of broken lift.
Oliver L.
Allianz climate control were great! Super detailed and thorough service of our ducted air conditioning for about 2hrs on site. Cristiam the technician was awesome 🙏
Jason
We recently had our ducted air conditioning system replaced and couldn’t be happier with the experience. Their current google rating really reflects their level of service, From start to finish, the team delivered excellent customer service and made the whole process seamless.

Everyone we dealt with — VJ, Eric, Brody, Mosd, Harry K and Ionnaes — was friendly, knowledgeable, professional and always punctual. They were respectful of our home and took the time to explain everything clearly, which gave us a lot of confidence in their work.

We really appreciated the trusted advice provided throughout — it never felt like a sales push, just honest recommendations tailored to what we needed.

The operations were also very well organised. From the initial booking, through to installation and final payment, everything ran smoothly and on schedule.

Highly recommend this team if you’re looking for a reliable and professional air conditioning company.
M. G S.
The air conditioning service was outstanding. The technician arrived right on time, communicated clearly throughout the visit, and provided helpful information after the job was done. He serviced the equipment thoroughly and professionally. Couldn't be happier with the experience—highly recommended!

Update. March 2026

AGAIN! We had an outstanding experience with Alliance Climate Control, thanks to Gabriel & Nicolas.

They were extremely professional from start to finish; quickly diagnosed and resolved all of our air conditioning issues with confidence and precision. What really stood out was how informative they were, I was clearly explained the problems, the solutions, and how to prevent future issues.

The attention to detail, efficiency, and friendly approach made the entire process seamless. It’s rare to come across someone so knowledgeable and genuinely committed to great service.

A huge thank you to Gabriel and Nicolas; outstanding service.
Gail G.
Service is fabulous. Great customer service. Professional and very competent technician. I would recommend without hesitation.
Martin B.
Charles, James, Aden and JJ arrived on time and completed the installation in an exemplary professional manor. I would recommend the team to anyone. Cheers to you chaps.
Benjamin C.
I contacted Alliance Climate Control, due to leaking water from my air conditioner. I had Gabriel come to evaluate the condition, and he gave me quotes and explained options. He immediately scheduled the job through a phone call with the office. 2 weeks later, I had Emre and Luke come to my apartment to properly do a deep clean on my air conditioning system. They both did a fantastic job within 2 hours. After the AC is properly cleaned. It works perfectly and feels like new again. Really happy with the job they did. I think I'm going to do this every 12 months as they recommended.
Bill S.
The team led by Bokhan did an excellent job on the installation. They worked through the bad weather to get the job done, and were always ready to provide us feedback when needed. The instal team and the electrical team were very professional.
We would highly recommended Alliance Climate Control for their high quality work.
Helen C.
Dylan and Connor were punctual, professional and a pleasure to deal with. Painstaking in their work, they did an excellent job servicing my airconditioning unit.
Alison H.
Great service. Damon & Brendan arrived on time, worked quickly, explained everything, tidied up. Thank you!
Tim A.
Superb service - Ivan and hist team worked assiduously all afternoon to provide everything and more that I asked for - well beyond the call of duty! He and his team were receptive, polite and just got on with it. The best service I have ever had in fact.
Iva S.
Gokhan, Can and Niko have installed our new AC and removed the old one. Professional, kind, polite and very respectful. They cleaned all rubbish and packing materials from the works. They left the area clean and all the works have been done with good workmanship. Very careful with our belongings. Happy with the installation. Electrical works are still ongoing.

Edit to add the electrical installation- Mohamed and James were amazing. The job was very long, but the persevered and did a very nice neat conduit. They cleaned up after drilling and the cut offs- very neat work and great quality. Very polite and professional.
AC works ! Thank you for your services, would not hesitate to use ACC crews again.

I had a second job done by ACC - amazing electrician Mohammad and cannot fault his work. Always checking when things got tricky 😅 but we solved all the issues on the spot. He replaced our 24 years old main switch board and created 2 new outdoors el sockets. Neat, tidy, polite and very efficient. Even our cat liked him ☺️. Thank you for your service!
Helen C.
Excellent service, punctual and extremely thorough and helpful.
