Sutherland Shire Air Conditioning Installation & Service

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.

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.

Excellent professional service.
Turned up on time, knowledgeable technicians.

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.

Fantastic team and great work on replacement system install. 👍 Huge thank you to Qais, Louis & Christian.

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!

Good, professional installation, very happy.

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!

Professional service, arrived on time and good communication throughout the appointment process

Excellent and efficient service.
Good humoured in spite of having to climb stairs because of broken lift.

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 🙏

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.

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.

Service is fabulous. Great customer service. Professional and very competent technician. I would recommend without hesitation.

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.

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.

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.

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.

Great service. Damon & Brendan arrived on time, worked quickly, explained everything, tidied up. Thank you!

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.

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!

Excellent service, punctual and extremely thorough and helpful.

I was happy with the service from Alliance through the whole process. Harry spent a alot of time at our house discussing the various options for aircon (ducted vs. Split systems) and the pros and cons of each - he even tried to find the manhole access to our roof. He was also very responsive to questions I had about the quote once we'd made a decision.
BJ and Carlos came for the install. They were very professional, did a good job of cleaning up afterwards, and spent time explaining the whole install process and how to use the systems once they had left.
I would use Alliance again for any further aircon installation. I was really happy with their service and the quality of the work.

I had a fantastic experience with the entire team who installed my air conditioning system. From the initial coordination to the final installation, everything was handled professionally and smoothly.

A big thank you to BJ, Theo, Can, Matthew, Cara, Eric and Will — each of them was knowledgeable, friendly, and clearly took pride in their work. The team arrived on time, communicated clearly throughout the process, and left the place clean and tidy after the job was completed.

Highly recommend this team to anyone looking for reliable and professional air conditioning supply and installation. Couldn’t be happier with the result.

P.S. Andre returned to install the wooden aircon cover—fantastic job, great energy, and super efficient. Really appreciated it!

Very professional. Great company. Efficient.

We are so very pleased with the installation of our new system. Kevin, Dragan and Ivan were so professional, thoughtful, with every aspect of the installation. Kevin’s instructions to me re the control pad were very clear with him constantly checking that I understood all aspect of the control panel. Their clean up and the way they left our home on completion was just perfect.
Kevin, Dragan and Ivan are a credit to your company, we feel very fortunate to have had three such competent team members of Alliance Climate Control carry out our requirements.

I can't speak too highly of the service we received from Alliance. From first contact and ongoing attention from Cara and Luke in the office to the assessment stage with Steven, the service was courteous and efficient, answering all our questions without hesitation.
When it came to installation B.J. and Theo were very prompt and helpful, taking great care to ensure that we were well informed and happy about every stage , leaving us with written directions and a demonstration of how to use the controller.
We have no hesitation in highly recommending Alliance.

Thanks Aden and Ryan for your amazing work and leaving the place so tidy afterwards.

Stephen, Rahul and Alex were all very professional and did a fantastic job on our system. Highly recommended

Dylan phoned 30 minutes before arriving. He was clean, very efficient, knowledgeable and thorough. He patiently walked me through the timer process and left written directions. We kept him longer to answer questions. He did not tear out the door.
