Hitachi Air Conditioning Sydney

I had a fantastic experience working with the team at Alliance for some maintenance and cleaning for the AC in our home. Damon was incredibly knowledgeable, professional and friendly. He did a thorough examination and talked me through the Pros & Cons of various levels of servicing. The quality of the works carried out were impeccable. Will be working with these guys again.

Alliance Climate Control were very prompt and efficient when fitting our air conditioning unit. Jonathan, Juan and Kim were thoroughly professional and completed the fitting in good time. Everything was left clean and tidy . I would highly recommend them.

Alliance Air conditioning just installed my new Mitsubishi unit. I chose them because their past service was always good. Today Tommy, Staad and Samet did the new work. Awesome team. Very efficient workers, explained every aspect of what they were doing with photos to show what I couldn’t see. No blaring radios, no loud voices or swearing. Lovely workers who cleaned up beautifully afterwards. They can do regular electric work too, so I will have no hesitation in calling them back when needed in the future. AWESOME WORK, thank you guys!

Aircon service and update

From the initial quotation to the 3 PM installers, it was excellent to deal with Alliance! They were professional, fast and made an extra effort to take care of the house. Thanks guys!

Thanks BJ, Theo, Moe and Jake. I think it was probably a challenging installation but they were totally professional, friendly and had great communication. Thanks team! Now I'm looking forward to the warmer weather so I can blast cool air into what would otherwise be a very hot room!

We had a tech from Alliance booked yesterday for a service call on our air con system. A really decent, engaged operator who couldn’t do enough for us through his visit. There was even a couple of extra, system housekeeping tasks that he undertook in a really discrete manner which we didn’t discover until after he’d left. This company has done our air con work for some years now, and we can’t fault them. Thanks very much to the Alliance team (and Emre) for the outstanding customer service.

Absolutely wonderful service from these wonderful guys — Evan, Maisam and Can! They were so friendly, helpful, and professional, and made the whole experience so enjoyable. Their customer service was outstanding, and they really went above and beyond to make sure everything was taken care of. Thank you, Evan, Maisam and Can, for your amazing service! You guys are fantastic and truly deserve the recognition. Highly recommended! ❤️👏 Aircon Installation

Incredibly impressed by Alliance Climate Control and the technicians/installers that came out to help us with our new air conditioning install. We were lucky to have B.J, Theo and Shazim. They were all polite, friendly, knowledgeable and professional. Customer service from the installers and phone line is great. If you're looking for a new air conditioner, maintenance etc I would highly recommend Alliance. Thank you heaps!

Alliance was recommended by a friend and the experience was seamless from James as the initial contact to the installation team headed by Jonathan Juan Kim and electrician Charles. All team members were polite and introduced themselves and cleaned and tidied after themselves. We were kept informed through the whole installation process . Any issues were discussed with us and resolved. Would definitely recommend

Ahmad, Louis and Carlos were fast, efficient and polite. I would definitely recommend them.

Tommy, Staad, and Charles did an excellent job installing a replacement split system. Charles took time to work out the most efficient cable routing. Tommy led the team in an installation where the outdoor unit needed to be maneuvered over an outdoor cat enclosure (catio). Calls on approach and arrival on time helped us too.

Super fast and professional install of split system in tricky spot

Alliance were great from start to finish, tailoring their air conditioning solution for us to meet our needs, and all at a great price. Very happy with the result, would highly recommend.

Excellent service - the team went above and beyond - thank you!

I’m pretty satisfied with the project from the beginning to the end! The installation team wit Ivan, Maisan and Mosa were very efficient and punctual! After completing their work they cleaned and removed all the debris and vacuumed! I was quite pleased and hopefully the new system will work perfectly, as I have not used it since the installation as there is no need due to the weather conditions. Ivan gave me the tour and clearly explained how to operate it! Thank you 🙏

Charlie, JJ, James , Mia and Tia, Lila Were here for most the day and all of them were terrific: efficient, charming, and very professional Charlie came back for another afternoon checking wiring and power points and again was charming and efficient and tidied up after himself JJ was very good at organising everything and making sure all was working before he left I am very grateful to them all

Christian is great and extremely professional his help was much appreciated

Damien did a great job. My aircon was absolutely filthy and he made it look brand new. Would happily recommend

Andre Muller came out today to conduct an eco clean of air conditioning unit to get rid of a build up of mould. He was punctual, polite and very professional. I was impressed by his efficiency and workmanship.

All members of the Alliance team I dealt with were knowledgeable, respectful, and friendly. During both the inspection and the follow-up visit to complete the work, they took great care to respect our home and carried out the job professionally, leaving everything clean and tidy. The entire process went smoothly, and the price was fair considering the high quality of the service provided. Their excellent customer service stood out, and I would happily recommend then to my family and friends.

I would like to thank Jonathan and his wonderful team with Juan, and Jacky for this expertise and professionalism. They were absolutely wonderful and I would recommend them any day of the week. Thank you so much. Jane and Nabil.

⭐⭐⭐⭐⭐ Outstanding Service from Alliance Climate Control! I honestly couldn’t be happier with the service I received from Alliance Climate Control. From the very first time I reached out for a quote, the entire experience has been nothing short of excellent. The communication and professionalism from the team were fantastic from day one. Harry, who came out to provide the quote, was extremely professional, knowledgeable and easy to deal with. On top of that, their pricing was by far the best I received — making the decision to go with Alliance an easy one. I also had Kody come out to look at another request I had, and once again, the service was exceptional. Darra, the installation engineer, did an outstanding job. He was professional, thorough and clearly took pride in his work. And the service didn’t stop once the installation was completed. James followed up afterwards to make sure everything was going well. That level of after-sales service really says a lot about the company. I genuinely cannot find anything to fault. Every person I dealt with was friendly, professional, knowledgeable and genuinely committed to providing great service. Alliance Climate Control really are the complete package — great people, great service, great workmanship and great pricing. I’ll definitely be using them again in the future. They can have my money any day! 😂 If you’re looking for an air conditioning company, I highly recommend Alliance Climate Control. You won’t be disappointed. 10/10 service from start to finish! 👏👏👏
