Thank you, Zac for your assistance.
We greatly appreciate your follow up and the job done by you and your team. I would have no hesitation in recommending ACC

Tommy, Shaad and Kim did an amazing job on installing our air-conditioning. They took great care of our place - it was cleaner after they left than when they arrived! They were prompt, polite and professional and I couldn’t be happier with the work they did!

Jonathan & Eric were excellent. Very respectful and managed to do a tricky install of a new machine to update our old system that stopped working. They were efficient and did a great job, I would highly recommend Alliance and this team for any new aircon installations.

IF I CAN GIVE YOU A MILLION STAR RATING its not enough. Thank you to B.J, THEO, LUKE,PETER LIAM and the new guy working with Peter the electrician. Amazing customer service, excellent work outstanding professionalism and for most very respectfully. You guys are a great assest to Alliance climate control
THANK YOU FOR THE AMAZING WORK YOU DONE AND EXPLAINING EVERY STEP OF THE PROCESS.

Alliance provides excellent services and a honest company. Jason is the best tradesman I ever see. He is very professional and friendly. He explain the issues and solutions very clearly. I certainly recommend Alliance and particularly Jason to anyone need aircon repair and service.
They are rare example of service companies should be.

We had a new aircon unit installed by Gokhan and Louis from the Alliance Team. They arrived on time, clearly explained what needed to be done, the installation was high quality and they cleaned up before they left. Highly recommend.

We couldn’t be happier with the outstanding service from Alliance Climate Control! The team delivered a truly seamless installation of four split systems at our home (Service Ref. #101598) from start to finish.

A special commendation goes to Ahmad Maisam and Meedy for their exceptional leadership, organisation, and genuine care in addressing our needs. Their professionalism, clear communication, and attention to detail made the entire process smooth and stress-free.

The workmanship was excellent, the team was punctual and respectful of our home, and everything was left spotless at the end. Simply put—the best team ever. Highly recommended to anyone looking for top-tier air conditioning service!

Andres from Alliance was excellent, professional and very clear. Our units are now operating perfectly and he detected a major issue and presented multiple solutions. Would recommend the service highly.

I couldn't be happier with the excellent service and clean provided by Emre.
He was punctual, thorough with his assessment of my aircon units and managed to identify the source of why my aircon has a mouldy smell. He was professional, knowledgeable and clear with his explanation of what can be the problems as well as recommending appropriate options to address the problems.
5/5 will call upon his services again if my aircons ever give me grief (though I doubt it with the level of servicing he performed).

Awesome company, awesome service. Quick reliable, very friendly and very informative.

Class act team! Love your work!

Pete Mac.

Gokhan and Louis did an amazing job installing my air conditioner! We had them install a split system in our bedroom, and couldn’t be happier

Their communication was excellent - explained the whole process and were very helpful and accommodating. The little things like helping to test different power mains to find the best configuration, the care they took to cover up and move my furniture, and the spotless cleaning job they did afterwards really set them apart. They even gave us a small gift bag at the end, which was a nice touch.

Highly recommended to go with this company, they are professionals through and through!

I had a great experience from the first time I called with my initial enquiry until the completion of my installation. Excellent communication, customer care and follow up communications. I felt that I was being looked after throughout the entire experience. All of the technicians and tradesmen were very kind and extremely professional. I was kept updated throughout the installation. My place was left clean and tidy. I highly recommend this company - thanks!

Ivan, Brody, Miguel, B.J, Theo and Tim were amazing they kept everything clean and even without a lift they carried everything up and down. They finished in record time and I couldn't ask for a better team!

Air conditioning service found no problems. Dylan was excellent.
Electrical check found no problems. WAs also able to book for additional power points. Charles was excellent. Walked through all options.

Great team of friendly, efficient guys. Highly recommended.

Jason arrived on time. I was very impressed with Jason’s performance and his knowledge of the system we had. Jason explained in detail what was done to the system and suggested the best way to clean the filter when it requires cleaning.

Emre was allocated to help with the aircon service for my apartment. I was very impressed with his professionalism. He is one of few dedicated technicians I have come across as knowledgeable who explained everything in details, patient with my questions, friendly, polite and on the whole, he did an amazing job. A very happy client. Thanks, Emre! Highly recommended!

One of the few vendors who did an on-site inspection before install and took into account my requirements. Gokhan, Louis and Nicholas did a great job with an installation of a split system to an upstairs bedroom. Routed relatively well to avoid outside challenges. Left everything nice and clean afterwards.

Thank you Tommy, Kim and James for your professional courteous service this week. Very efficient and neat work. Explained options well and provided the best solutions for our awkward house.

Such a great team from Alliance just installed my new air con - life changing! Thanks to B.J., Theo, Tim, Emre and in the office Peter, T.K. and Will

5 Star Service, fast, efficient, clean and a pleasure to deal with, from initial consultation with Kirk, follow up from Zac, and great work by installers Matt, Maran, Jono, Tom & Tom!

Update - latest review for the Electrical Safety Inspection on 29/12/25 and Electrical Work on 07/01/26.

We are very impressed with Joshua, Vash and Mohammed. So, we are giving each one of them 5 stars.  Joshua was very detailed and very systematic when he conducted the safety inspection last 29/12/25. Also, giving us practical tips about safety and to monitor the old power points. He also patiently explained the importance of getting the electrical system and smoke alarm up to code and all the things that needs to be replaced. He is also courteous in his behaviour and how he engages with us.

Vash and Mohammed arrived early for the electrical work on 07/01/26.  These young blokes are very thorough, they know what they're doing. They worked as a team and non-stop for several hours. They are also impressive, respectful, and polite. Before they left, they double checked everything and even vacuumed the dining chairs and floor to keep thing tidy. We learned a lot from them and how to use electrical extensions safely.

These young men ( Joshua, Mohammed and Vash )will go far. They arrived neat, clean looking and ready to do the job. They have a high standard in workmanship, dedication and most importantly they have the right attitude about their work and how they treat us.

Kindly let them know that even though they might think they just did the electrical work. For us, they did more than that, they contributed to our health and safety.

Please, don’t stop inspiring these young men to continue developing their trade. They are the kind of professionals that our society needs. Thank you. Jennifer from Macquarie Fields.

Updated my review to include our recent service experience October 11, 2025 with Gabriel.

I want to share our recent experience with Gabriel, who provided a complete tune-up and service on our Fujitsu multi system last October 11, 2025. Overall, our experience was outstanding. My husband and I truly appreciate Gabriel’s dedication—his professionalism, expertise, and meticulous care stood out throughout the visit. He walked us through the air-conditioning health report, clearly explaining the tasks he completed and the performance of our air conditioner, while also offering practical and easy-to-follow maintenance suggestions that put our minds at ease.

Gabriel consistently demonstrates professionalism and a positive attitude toward his work, just as he did in January 2022. His respectful and polite manner made the entire process enjoyable. Thanks to Gabriel’s thorough service, we feel much more at ease knowing our air conditioner is in top condition and our home’s air quality is supporting a healthy lifestyle.

We are happy to recommend Gabriel to others, and we hope to see him again in another year or so. Thank you once again for your excellent service—Gabriel is truly deserving of 5 stars. Thank you, Gabriel.

On the 19th of Jan 2022 an inspection was conducted by Gabriel. He was punctual and did a thorough inspection. He came back with Bailey for the AC cleaning and tune up on the 21st of Jan as per agreement. We have rated both of them 5 stars for the following reasons and base on our observations. Punctuality, tidy in appearance and work, very knowledgable with their trade, well mannered, they did a meticulous job in servicing our AC. Most of all, they were both efficient because they worked as a team. We are a very happy customer. Thank you Gabriel and Bailey.

We are delighted with the level of service and the quality of the job. The technicians, Mitesh and Nick were fantastic

We have already referred one of our friends to Alliance

Alliance has done an amazing job from providing the solution , quoting and install by Vy and his team. The install was competed in one day with an even better outcome than originally designed. Well done to the entire Alliance Team and would highly recommend.

Charles and Aaron arrived on time and were patient and professional while answering all of my questions. They provided clear, written quotes, explained exactly what was included and what wasn’t, and even suggested and implemented a solution on the same day for a problem that wasnt even part of the job they initially came out to do.

We were very pleased with the whole process. Thank you.

Service Technician arrived within the advised block time. He carried out the required service very efficiently and provided a written report of the condition of all aspects of the A/C and cleaned all the filters, unit cover and the outdoor unit. Very satisfied with a thoroughly professional performance.

Very proficient and easy Company to work with. Quality product and workmanship.

Had my ducted aircon serviced. Very happy with the professionalism from booking the appointment to service provided by Andre Galvis.

Job is 100360 and technicians are Luan, Meedy, Eric. Their work was impressive and thorough. I like it all!

Had new AC units installed and an old one replaced. My experience with ACC and their team was fantastic from start to finish. The team that supported us included Liam, Vash, Will, B.J, Theo and Jun. Cannot thank them enough for being such a pleasure to work with. They were incredibly professional, good at what they do and showed great care in helping us with our installations. I would highly recommend ACC and this team! Thank you to the Team again!

I recently had air conditioning installed by Alliance Climate Control and couldn’t be happier with the experience. From start to finish, the service was outstanding.

A special mention to Vy, Luan, and Eric, who did an exceptional job on the day. They were professional, punctual, and clearly took pride in their work. The installation was carried out efficiently, with great attention to detail, and they left the place clean and tidy afterward. They also took the time to explain everything clearly and made sure the system was running perfectly before they left.

Highly recommend Alliance Climate Control to anyone looking for quality workmanship and excellent customer service.

When our apartment’s 12-year old Daikin air-conditioning system broke down, we called a few A/C companies, including Alliance Climate Control (ACC). We were immediately impressed by ACC’s professionalism, promptness and very friendly office staff and service technicians. Shazin and Brandon did an excellent job diagnosing the system’s problems and providing a range of options as to its repair and on-going guarantee conditions. Once contracted, Yunis, Nico and their colleague (whose name, regrettably, I have misplaced), took great care in replacing the larger components on the building’s roof and replacing the five individual control panels in our apartment. Not a trivial job, given the roof accessibility in our building. Conner and Steven worked hard on a following, very hot day to diagnose and correct a tricky leak in the coolant pipe on the roof that runs to the apartment. With the pipe sealed, they commissioned and tested the system thoroughly. ACC kept us well informed throughout the entire process. We are very happy with ACC and have no hesitation in recommending them!

Absolutely wonderful service from JJ and then 2 guys today Charles and ? They very professional and just nice guys. Thank you

Job #100840 Andre was punctual, presented himself well and knowledgeable. He was thorough in his servicing and we're happy with the results.

We recently bought our first home and when our AC started leaking into our ceiling we were so panicked. The Alliance team were so helpful, they got out to us quickly and gave us a very honest assessment. We were lucky enough to have our new AC installation completed by Qais, Cris, Eric and Mike and they were fantastic. They were so professional and super fast, we have been so happy with the service and are so glad we decided to employ Alliance to replace our old unit.

BJ & James did an excellent job installing our new Daikin split system…they were on time, professional and very tidy. Vash & TK did the electrical wiring and were great to deal with too. Aysa did the original quote and was brilliant, great guy and very helpful. Also spoke to Will & Cara in accounts. The Alliance guys are a super team and I would definitely recommend them for all your a/c needs!

In my view, Alliance provides a professional and responsive electrical service. My wife and I were impressed by the quality of the work undertaken by Charles and James.

Very good and reliable service
Another happy customer
Thanks Vy, Luna, Eric, and Mosa!
