Shabi, Louis & Maisam were very efficient, polite and cleaned up very well after installation. Very happy with the service.

Fast professional job installing air conditioner by Shabi and Louis.

Huge thanks to Charles and the team at Alliance. I had my air conditioning installed today and couldn't be happier with the result. Thanks guys !

Tommy, Kim and Meedy show up exactly on the dot they informed me, came in like old mates whos dropping by to install your aircon. Super friendly, explained really well about the AC youre installing. clean and quick job, no dramas. Thanks for the awesome job.

Exceptional level of service provided by Alliance to repair our Air Con unit. From quoting to communications to completion of job - this company goes above and beyond. Highly recommended

Dara and Guan did a great job installing an air in at our premises yesterday. They did a great job. They were competent, confident, efficient joyous people. If excellent service as well as a great product are important to you, I strongly recommend this company to you.

Wonderful workers. Efficient, polite & hard working

I am so impressed by Damon from Alliance Climate Control who has just finished servicing my 3 air conditioners. He was efficient and polite and was very willing to answer my questions and his answers gave me confidence that he knew what he was doing. So impressed I’ve signed up for a 3 year maintenance plan. I highly recommend this bright young man and the company itself that presents as very professional.

VY - Luaw- Miguel were amazing! Great professionals.. thanks Team! The outdoor installation and in room look great!

Excelente work very profesional. Highly recommended.

Amazing maintenance service one year after the installation. The technician arrived on time, on the dot effectively, and spent 2 full hours cleaning filters and aircon unit bodies, checking everything etc. The units and filters were in a good condition, but this demonstrates the thoroughness of the service.

From quoting to install, the Alliance team were helpful, professional and accommodating. They were competitive on price and went the extra mile on customer service

Damien serviced all 5 of our conditioners which took most of the day. Cheerful, friendly and efficient. Quietly got on with the job.

Kyle did a terrific job today servicing 3 split systems, great communication, very tidy, and good explanation of everything he found.

I also had Ivan Mosa and Brody install a new system in my bedroom. Very clean and neat job, terrific communication and I’m super happy with the results.

The professionalism blew me away. They were amazing from the quotation process through to the installation. When there was a bit not scoped correctly they honoured their fixed quote. Could not recommend these guys anymore espessially Yasin, if there were 10 stars I would give it to them!

On time, excellent communication when arranging aircon service. Friendly, efficient knowledgeable and courteous technician (Damon).

Rodriguez, Ivan and the Alliance Team were very professional and did a great job explaining everything to me and cleaned up thoroughly after the job was done. They are a credit to the Alliance team.

We installed our air conditioning 5 years ago. The installation was perfect and we have had no issues in all the time we have owned the system. We had to get them back because one unit was leaking water. They were prompt to attend to the problem, admitted that some of the problem was their issue and they would cover the fix themselves.

They owned the problem. They are always very polite. The engineers they send out are highly professional, leavve no mess, take off their boots and are good at communication with the client.

I've recommended them to many people..

Charles & Dara installed a new air conditioner in the loungeroom of my period home in Sydney's eastern suburbs and did an outstanding job. They talked me through the whole process and checked that I was happy at every step. They were also very clean, used loads of drop sheets and even vaccumed which was such a pleasure to see how much they cared and Dara quickly problem solved when it was necessary to alter plans without delay or extra cost. Charles also spent the time to carefully show me all aspects of the units operation and thoroughly checked through all its functions leaving me without any worry. This team is amazing and offer quality workmanship and peace of mind at every stage at a good price. I will definitely be using them again! In fact I have planned another air conditioning installation in 2 weeks!

Great I am so happy, finally can get a good sleep.

Excellent service by friendly and knowledgeable technician

Installation went very well. Great crew of happy workers. Efficient and polite.

Both team members were really lovely, polite and did a great, honest job. We were really happy with the service we received.

Alliance installed our air-conditioner. The whole team did a great job, but I specially have to acknowledge the electrical team who were given a bit of a difficult task running the wiring as we didn't have access under the floor. However they were meticulous and installed it to perfection. They were very thoughtful about covering areas of our kitchen so that it wouldn't be covered with dust too. We really appreciated the considerate nature of how this was managed. Many thanks!

We are very happy with our aircon installation (multi-split system). Alliance did an amazing job and were very thorough. Thankyou to Aysa for answering our lead up queries and to Tommy, Gokhan and Miguel for their professional, friendly and efficient work on the day of installation.

they were 100% and cleaned up really well. They came back a day later to make sure everything was OK. Thanks!

Great service, professional and friendly :).

BIG thank you - Eυχαριστώ - to Giannis (Yiannis) for patching up a few spots after our air con installation! As with any work done on an older home, we expected a few areas might flake or chip, totally understandable.

True to their word, Alliance Climate promised that if anything was scratched or damaged during installation, they’d fix it afterwards. Sure enough, Giannis reached out and came by to repair and paint everything back to good-as-new.

This guy is fantastic, he patched up everything perfectly!
Thanks again, Giannis, and thanks to the whole Alliance Climate team for standing by your service! 👏

HUGE shoutout to the Alliance Air Climate Control installation team — Vy, Luan, Kaspar, Harry (the MASTER ceiling cutter for old houses!!), Liam, Charlie, the electrician, and their co-worker — every single one of them was terrific and so friendly over the two days! 👏

We’ve just had our 5-zone ducted system plus 2 split units installed, and my wife and I couldn’t be happier with the result. Previously we had a gas heating system installed by another company, and it wasn’t done satisfactorily. The difference with Alliance has been night and day.

What really stood out to us was the strong team feel — they work seamlessly together, communicate clearly, and talk you through each step of the process. They also came up with excellent ideas to maximise the efficiency of our units.

A big thank you as well to James Greene, who provided the initial quote. He was highly professional, patient with our questions, and came up with a plan that matched exactly what we were hoping for.

Needless to say, my wife and I will be recommending Alliance Air to anyone looking for air conditioning installation — an outstanding experience from start to finish! 🌟
