Andrei Muller from Alliance Climate Control recently serviced the air conditioning at my home and did a fantastic job. He was very professional, polite, and clearly experienced.

He made sure everything was checked properly and kept the workspace clean and tidy throughout the visit. It’s always great to deal with someone who takes pride in their work and respects your home.

Very happy with the service and would happily recommend Andrei and the Alliance Climate Control team.

Huge thanks to Alliance Climate Control for a fantastic installation.

A special mention to Giannis Koutsourais (the “Golden Greek” painter) and Liam Stuart (plasterer) who finished off the air-conditioning install. Both were on time, highly professional, and clearly take pride in their work.

The workmanship was first class and the finish looks excellent. It’s always great to see trades who care about the details and leave everything looking perfect.

Highly recommended.

The team of technicians who installed our Ducted Air Conditioning were very professional and the most respectful trade staff we have ever engaged at our home. Their focus on clean and efficient work was exemplary.
We would recommend this company to anyone who are contemplating engaging them to do any work for you.

Damon was very courteous and professional. He provided a thorough maintenance of our split system as well as helpful tips for keeping it running well. He kept his work area tidy and cleaned up afterwards. Thank you.

pleasure dealing with the team. Very tidy and efficient. Very happy with the result dealing with Alliance. The team I dealt with was Matt, Callum and Nikola. Thanks guys

I’m very impressed with Kody’s professionalism during the air-conditioning diagnostic at my apartment. He thoroughly explored all possible options and was careful not to jump to conclusions, which really demonstrated his patience, expertise, and integrity. It was clear he was focused on finding the right solution rather than being money-oriented.

The team also went above and beyond by waiving the initial call-out fee due to a booking error, which was a very appreciated and thoughtful gesture.

Highly recommend their service. Wishing Kody and the team a Merry Christmas and a Happy New Year!

**Adding on post 1st visit**
Following my initial review, I had to call Kody back as my aircon started leaking after the first visit. We discussed a repair that might involve cutting into the gyprock to resolve the issue.
On the day, Dylan, Colin and Ioannis attended and were extremely professional and accommodating. Instead of immediately cutting the gyprock, they took the time to explore alternative solutions and managed to fix the issue without opening up the ceiling, which I really appreciated.
Big shout out to Ioannis as well for offering to patch up some paint on the ceiling free of charge - a very thoughtful gesture. Really impressed with the team’s creativity, professionalism, and willingness to go the extra mile. Highly recommend them.

Amazing work very detailed and thorough with ensuring what needed to be done and also recommending what could be fixed. Completed work beyond expectation and timeframe, will recommend to others

Dylan and Connor were very professional, they did a great job, tidy and kept me informed about everything they were doing.

From quote to install I had nothing but fantastic service. The tech who quoted was patient and explained everything asked about. The techs who arrived to install were polite and worked quickly and efficiently. They cleaned up after themselves and explained the use of the system to me. All round I’m really pleased with the whole experience.

Excellent service from Aden & TK. Professional, polite & got the job done. Highly recommend, a credit to your company.

Excellent work from team professional and proficient. Tommy, Dragan, Emerson, Ben, Kaspar and Harry

Mohamed and Ryan of Alliance Climate Control took care of the electrical needs of the installation and they were very efficient and worked well.
They communicated with us and instructed us with a detailed summary of what they did and provided us with contact details.
Very happy with how they just got on with the job.

Split system air conditioning installed by Alliance. Great non-intrusive design initiated by installers. Ie, the cabling was put under the upper floor and then into an existing air vent, then out under the eaves and down behind existing drain pipe, causing minimal visual impact.
Plasterer work and electrical work also excellent. (Painting to be done by owner. My choice.)
Very happy with the outcome and the service provided by Vy, Eric, Meddy, Harry, and JJ. Job no. 99701.

We are both very happy with the team who installed our multiair conditioner. Excellent team who are proficient in their work.

Ahmed, Louis and Maisauri did an amazing job in extreme conditions.
They are certainly a great asset to the Company and we would have no hesitation in recommending them.

Punctual, friendly, knowledgeable and in formative. was given options and choices of work that needed to be done.

Matt, Nick and Carlos from Alliance Climate Control were fantastic. They installed our air conditioning and the whole experience was seamless from start to finish. The team was professional, efficient and incredibly helpful throughout the process.

They took great care in our home, covering the floors and all nearby valuables with drop sheets before starting work, and when they finished the area was completely spotless. It’s clear they take pride in what they do.

Highly recommend Matt, Nick and Carlos from Alliance Climate Control if you’re looking for a reliable and professional team.

The technikcian arrived on time, clearly explained what he was going to do, worked efficiently, and tidied up after completing the job. He was very open, professional and easy to deal with.

Vy, Eric and Meedy! High praise for this exceptional team you have. They brought great expertise and customer service! Job id 103898. These guys were such a pleasure to have in my home and the quality of the finished product is top notch! Alliance CC are very lucky to have this crew on their team. I couldn’t be any happier. Thank you Vy, Eric and Meedy.

Fantastic service. We had a bit of a difficult job and they came in with ease, no issues, job done. Very pleased !

Extremely happy with the light and switch installation. Good clean up and return of furniture that was moved to correctly position the installation. Many thanks to Mohamad and Ryan. Keep up the fantastic work.

It was a complex installation - a multi split system - in a small strata unit too high up for ladder work. Liam, BJ, Theo, Aaron & Ken made it fit together & the installation on the day was challenging, but hassle free. Everything cleared away and back in its place at the end of the long day.Kathrine & Luka in the office made the set up easy.

Excellent service, technicians appointed were superb very polite and respectfull during their visit at our premises. They were excellent pointing out the incorrcect filter mesh was used on initial installation allowing a considerable amount of dust passing through the return air grill and highly suggested we replace this with a more appropriate filter media. Left us a diagnostics sheet showing all checks complete which was also a positive.

Late arrival due to meeting for technicians,
Thereafter did a good job, friendly and helpful.

Damon was professional, friendly and efficient. Every service we have ever had has been great. Alliance are wonderful to deal with.

Alliance CC runs a streamlined service from first planning to installation. Our installation manager Goran was very accomodating as we worked through a prolonged strata approval process. The installation itself was efficient with several workers onsite under careful supervision by Sam. A couple of minor issues noticed after installation was complete were quickly rectified within 48 hours. We now have a flexible and economic system with internal Daikin units in 4 rooms suppled by 2 external Multi Inverters. Our only hesitation with this whole process was the trunking required externally, which is an unfortunate but unavoidable compromise to having the luxury of airconditioning.

New installation completed 20/02/26: Given our previous positive experience using Alliance CC we used them again to install ducted AC in our new house. Similarly smooth process and commitment to great customer service. James who quoted was very thorough taking time to walk us through the options and approachable in answering our further questions in the lead up. Yunus and his team including Matthew, Veysel and Carlos were courteous, efficient and careful with our property during installation. Thanks all!

Charlie & James returned to problem solve an inadvertent issue by the competent & amiable Andre. They tested all possibilities, & found the solution. They stopped another problem & promptly fixed that. They were pleasant & professional throughout. All sorted since.
Much appreciated, thank you.

We are extremely happy with the service we received from Alliance. From quoting, scheduling, installation, right through to patching and painting everyone we dealt with at Alliance was prompt, polite and professional. We had delays on our side of things due to issues with strata approval, but throughout Alliance remained patient and understanding (despite us having to reschedule the work a number of times). The work itself was high quality and the air conditioning system is fantastic. Highly recommended.

This was a tricky job replacing an inbuilt exhaust system for the kitchen. Alliance solved the problem and now I have a fantastic exhaust system . Thankyou

Affirming the wonderful service of Alliance. Reliable, professional. They fixed our air conditioning problem with clarity and efficiency. Mitesh and Andre were excellent. Thank you Team.

Great service from the Team and technicians Emre and Connor

Everything about Alliance was first class.
The service work was done no fuss by Dylan a nice young bloke. Thank you Alliance

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.

James did a great job and went above expectation to provide a cost effective solution

The service person arrived when he said he would, did the service efficiently, quickly and respectfully. The explanation of what was done was clear and the information provided comprehensive.

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.

Excellent service of multiple split systems by Emre and Connor. Very professional, friendly and thorough. Highly recommend and will definitely use Alliance again for next service.
