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

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.

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.

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.

We had an AC unit installed by another company over a year ago and it’s sadly had several issues. Kody MB from Alliance was an absolute life saver in getting us sorted out and further helped us in setting up a future appointment for maintenance.

I can’t stress enough how helpful, kind and professional Kody was. I would highly recommend Alliance, and Kody, for any AC jobs you might be considering.

Back in mid December 2025, the guys from ACC installed our air con and did a fantastic job. Liam was consultative throughout the quoting process. And thanks to Jono, Ben, Charles, and Aaron, the final installation of the indoor and outdoor units, as well as electrical work was delivered to a high standard of workmanship. They left everything clean and tidy, and we're very happy with their work.

It also doesn't hurt that they were friendly! Bonus points for being unfazed by our vocal little dog! Thanks guys!

Lisa J.
Re: Dais, Sayed & Christian
Hello,
I have been meaning to send this email for quite some time, but due to poor health, and lots of other excuses, I simply haven't gotten around to it.

I wanted to provide feedback for the above job number, as the boys really did work their arses off! It was a complicated job (which even I could see as a layman), and yet nothing was off-limits. They really did everything to accommodate the job, and my individual requests. As an individual, I am very particular and hold very high standards, and yet, they did not blink and eyelid.

I would also like to mention that all three of them were a delight to have in my home. It goes without saying, that they are a credit to your company, and it was an absolute pleasure working with them.
Kind regards
Lisa
Noah B.
