Awesome Job. Great work by BJ, Cristam, Peter, Blade, JJ, Liam, Will and all the team.

Impressed from first minute to last. Not the cheapest but they do not claim to be.

We were delighted with our experience with the Alliance team of Tommy, Nick and Luan. They went about the job professionally, expertly and with no fuss. They left the job site as they found it, perfectly clean. What a wonderful example of hard working young men and a credit to your organisation. All contacts with these young men were courteous and polite. Well done Alliance.

I'm very pleased with the service. 100% we'll be returning clients. Thanks Kody for being very professional. Appreciate the recommendations.

Great job Miguel and Andre thanks

A big thank you to Andres Iván T Yunus James and Harry. It ended up being a difficult job and they were helpful polite and did everything they could to ensure the job went smoothly. A lovely team .

ACC were fantastic - Had a broken mainboard in my dankin unit. Need parts which would take up to a week. They offered me a portable aircon to help with my sick kids temp issues and it kept us happy until the part arrived. The work was done quickly and easily and the aircon after a service and new mainboard is better then ever.... Insanely good service and will be 100% keeping these guys on speed dial for all my aircon needs at my investment and home property ongoing .

Very impressed with the quality of service and professionalism from Alliance Climate Control. The initial consultation was thorough and considered, the installation was very clean and respectful, and the back-end admin and communications were easy, straightforward and transparent. I'm very pleased with final product (ducted Ac). I've no hesitation in recommending Alliance. Thank you James, Ken, Shadi, Trung, Harry and Jason! You did a great job!

Very professional and prompt. Couldn’t have asked for a better service.

Dealing with Alliance was a smooth experience. With my ducted air conditioning system failing and summer approaching, I anticipated getting quotes and scheduling installation would take a long time.However, just a couple of days after my initial quote request, a representative came over and explained my options, following up the lot clearly via email.Once we decided on the best option for our needs and made the call, the installers arrived within a week.Installers were friendly and professional, double-checking everything before starting the installation and cleaning up thoroughly afterward.We are delighted with the service provided, and our home is now ready for summer! I strongly recommend their services! 👌Thank you Alliance!

Andre and James were excellent in installing our new air con unit. They really went the extra mile in something which wasn’t necessarily a straightforward job and were extremely polite and helpful throughout. Would definitely recommend.

Great job! Huge thanks to Kevin, Dragan and Miguel for a smooth and efficient process. The install was a hassle free!

A really thorough and professional installation.

Tommy, Nick, Julian and Luan were fantastic. We moved into our new house, enquired about air con with Chris (who was also awesome!), and within 10 days we were fully installed with ducted throughout and split cycle in one room. We are so happy with their service, communication and professionalism. Thank you

Raj our technician was on time and very thorough in his assessment of our problem

Shazim, the technician who performed the service, was excellent. Extremely competent, polite, turned up on time. Clearly a very skilled individual.

Yiannis from Alliance Climate Control came to my house to fix the damage that happened during installation. Not only did he do an excellent job. He also helped me with a stubborn bayonet connection. This in extremely hot conditions. All the staff are friendly and take pride in doing a good job.Thanks Jane

Andre and Miguel did our aircon installation and both were very professional and courteous. They explained the installation process, consulted with us on any details that needed clarification and cleaned up when the job was completed. Very happy with the service.

Great product and service. Friendly & helpful staff. Would recommend Alliance unreservedly.

I was impressed by the excellent communication and efficient installation. I would highly recommend them.

Alliance client control team installed new split air conditioner in my house today and it is great experience. B.J., Christian, Ivan are the best and awesome engineers ever and friendly guys, they did excellent and quality job and good customer service (they cleaned up everything even the outdoor gutter after work), so I very appreciate their service today. Also thanks very much to Alex, Chris and Keely! They are the customer service team members who did quotation, job booking and payment. Overall, definitely I will rate 200% satisfaction of my journey with ‘Alliance’ team. Regard, Joel Yang

Very professional and punctual. Great job overall

Thank you once again to the team at Alliance Climate Control. This was one of the smoothest home renovation projects I've experienced.My previous air conditioner was a complete nightmare after installation—I bought it from a certain large electronics store that handed off the job to unreliable third-party contractors. Within months, it started leaking from the base and couldn’t drain properly, it was angled weirdly. It became one of the most stressful events for me, especially during summer when we relied on the air conditioning. The constant repairs and cleaning added up quickly in both time and costs.When I finally surrendered and started to do my research i came across Alliance Climate Control. They not only promised to fix the issue but also ensure me they will install a new air conditioner the right way (they even stated this on their website - where they will make sure you are satisfied will their work before they finish). So when the team arrive, Kevin and Dragan took on a challenging job—my old unit was installed in an awkward position, with improper drainage and poorly done piping within the walls. But they were undeterred. They assessed the setup carefully, discussing how to best resolve the issues rather than just doing a quick install and leaving.Their attention to detail was impressive, and they left my place spotless after the job, ensuring I wouldn’t have to clean up after them. safe to say - my room is now cool and ready for the summer heat!The takeaway here: don't go with just any third-party installer. Air conditioning installations are complex, and cutting corners can cost you more in the long run. Alliance Climate Control's high ratings speak for themselves—they know what they’re doing.Thanks again, Kevin and Dragan—I truly appreciate all your help!
