Jason and Nicolas were great. They were efficient and did a comprehensive job!

Luke was really good today. He came to do a service and was so polite and considerate, first thing in the morning so we were all just getting ready to go to work and he quietly got on with the job.

We had our Air Conditioning serviced by Alliance. They were great. Christiam was professional, polite, careful, clean and got on with the job at hand. I would highly recommend them. Great service all round.

Ahmed, Louis, Cris and Liam did a wonderful job. I felt comfortable leaving them unsupervised in our home while we were out at work and they always gave me a full overview of the day in the morning and a report at the end of the day. They tidied up at the end of each day even though it was a 3 day job. Very happy - and now nice and warm too!

Response from the owner:Dear Catherine, What a wonderful review, thank you so much! It's great to hear that Ahmed, Louis, Cris and Liam made you feel at ease and confident leaving them to get on with the work. A three day job is no small undertaking, and knowing the team kept you informed each morning, wrapped up with a full report each afternoon and left everything neat and tidy at the end of each day is exactly the standard we strive for. And with the cooler weather settling in, we're especially pleased your home is now feeling warm and cozy! We'll make sure the whole crew hears your lovely feedback.

Excellent service. The guys helped me learn a few new tricks with my control panel as well. Explained in detail what they were doing and how it works, and after checking the air distribution through the ceiling vents, went back into the roof to tweak it just right.

Response from the owner:Dear Roderick, Thank you for sharing this, what a great experience to read about! It's brilliant to hear the team not only completed a thorough job but took the time to walk you through your control panel and fine-tune the airflow through your ceiling vents. That kind of attention to detail, going back into the roof to get the distribution just right, is exactly the level of care we want every customer to experience. We hope you're enjoying a noticeably more comfortable home as a result! Mel – Alliance – Air Conditioning, Heating & Electrical

The customer service was excellent and the installation for my new air conditioner was very professional and prompt..

I’m so glad I chose Alliance for my air con. From the consultation to post installation after care, everything has gone perfectly. Alliance has consistently delivered on their promise; they’ve turned up when they said they would, completed the job in the stated time frame and made sure I was happy with the work. The electrons even installed a towel rack for me - because they were there and they could. Nothing is too much trouble for these guys! Fantastic quality job and service.

Just had my initial inspection with a young man called Kyle. He was knowledgeable, polite, informative and friendly. I have locked in a date (of my choosing) for work to be done. I hope the technician who does the work also has the A1 customer service skills of Kyle. The lady i originally made the appointment with also had the A1 customer service skills. So far, so good Alliance - thank you!!!

We'll absolutely pass your kind words on to Kyle and to the team member who took your call; knowing their warmth, knowledge and professionalism stood out from the very first interaction means a great deal.

Ivan, Maisam and Mosa did an amazing job installing our new AC system. They showed up on time, they were courteous and clean operators and delivered a very neat finish. They did a really nice job fitting it in around our old terrace and were sympathetic to the outside appearance.

I recently used Alliance Climate Control to replace an old, broken air conditioner with a new ducted system. While their quote was higher than others I received, the level of professionalism and the final result made it worth every cent.
Our home has a very narrow roof space and significant temperature imbalances between rooms. Most companies simply told me what I wanted was unachievable. Jake, however, took a different approach. He was incredibly thorough—measuring everything and being completely upfront about the challenges. He walked me through several scenarios of what might happen once the roof was opened, giving me total confidence in their expertise.
The installation team, Yunus and his crew(Brody, Can and plasterer Liam) were professional, courteous, and went out of their way to accommodate my requests—including moving the outdoor units to a new location at no extra charge. Yunus made sure that each detail was perfectly executed.
The outcome is way better than our old system; thanks to Yunus, the new ducts are much better placed and the zoning works perfectly. The results actually exceeded my expectations.
I highly recommend Alliance Climate Control for anyone who wants peace of mind and a team that is willing to tackle difficult problems with honesty and skill.

Response from the owner:Dear Suzie, Thank you so much for such a thoughtful and detailed review, it truly means a great deal to everyone involved. Tackling a narrow roof space with significant temperature imbalances between rooms is exactly the kind of challenge we take seriously, and we're so pleased Jake's thorough approach and complete transparency gave you total confidence throughout the process. Yunus, Brody and Can will be thrilled to hear their care and workmanship on site stood out the way it did, keeping every detail perfectly executed, including relocating the outdoor units at no extra charge, is the standard we always aim to uphold. It's especially rewarding to hear the new zoning is working perfectly and that the outcome exceeded your expectations. We're so glad your home is now comfortable, balanced and ready for the seasons ahead, and we truly appreciate your recommendation. Mel – Alliance – Air Conditioning, Heating & Electrical

Response from the owner:Dear Teresa, Thank you for the ⭐️⭐️⭐️⭐️⭐️ review and for taking the time to share such generous feedback.

Routine service of a/c units. Alliance Climate Control had initially provided a 3 hour time window; Jason texted a 1/2hour prior to arrival and he & Nicholas were on time. They were attentive in listening to and understand my initial concerns. They were efficient and tidy in their work and then explained clearly what they had done. Overall excellent service. Barry

Response from the owner:Dear Peter, It's so lovely to hear your home comfort is in good hands, thank you for sharing such kind feedback. Regular servicing plays such an important part in keeping your system running efficiently and maintaining that warmth and comfort through the changing seasons, and we're so pleased Jason and Nicholas made the visit a positive one.

I received outstanding service from Jake, Ahmad, Louis, Callum Yas and Loannis. Highly professional, reliable and effective service from the inital quote to installation and then follow-up. Alliance was my highest quote but so worth every cent which speaks volumes about the peoduct and service I received. Absolute value for money. They went above and beyond to make me feel satisfied.

Kody was great explained everything that was going to occur. No hidden extras. Great communication and service

Response from the owner:Dear Iris, Kody is a fantastic ambassador for everything we stand for at Alliance, clear communication, no surprises, and a genuine commitment to doing right by our customers. We believe great air conditioning is as much about the experience as the equipment itself, and that means full transparency from quote to completion. So glad there were no hidden extras and that everything was explained upfront. Your comfort and trust are what we work for every day. Thank you! 🙌 Mel - Alliance - Air Conditioning, Heating & Electrical

10/10 customer experience and absolutely would recommend. Best tradies we've ever come across! Jason, Nick, Alex, Kyle were awesome and highly competent. After a lot of stress with 2 other aircon companies unable to solve our sensor and filter issues, Alliance came in and did an amazing job. Special shout out to Alex for diagnosing the problem so quickly, and to Jason for going above and beyond to fix it. Will be using them for the rest of our lives!

Matt, Carlos and Meedy installed the replacement ducted air con system at my home in Mona Vale. They went about it quietly, professionally and very respectfully. No dramas. Always available to answer my questions and consulted with me when decisions needed to be made. There was no fuss, just steady progress and completion on time. Exactly what I wanted.

Response from the owner:Dear Paul, Thank you for such a thoughtful review! Matt, Carlos and Meedy are a credit to our team, and we love hearing that the installation felt calm, considered and professional from start to finish.
