Excellent
The guys were great, fast and informative. Definitely go with them again.
Gokhan, Can and Niko have installed our new AC and removed the old one. Professional, kind, polite and very respectful. They cleaned all rubbish and packing materials from the works. They left the area clean and all the works have been done with good workmanship. Very careful with our belongings. Happy with the installation. Electrical works are still ongoing.

Edit to add the electrical installation- Mohamed and James were amazing. The job was very long, but the persevered and did a very nice neat conduit. They cleaned up after drilling and the cut offs- very neat work and great quality. Very polite and professional.
AC works ! Thank you for your services, would not hesitate to use ACC crews again.
Response from the owner:Dear Iva, Thank you for taking the time to share such detailed feedback about your experience. Gokhan, Can and Niko will really appreciate your kind words, taking care with our customers’ homes, working respectfully and leaving the area clean and tidy is something we place great importance on. It’s great to hear the workmanship met your expectations and that you felt your belongings were treated with care. We’re also glad Mo and James delivered such a neat and professional electrical installation. Long jobs can be demanding, but perseverance and attention to detail, especially with conduit work and clean-up are all part of maintaining our standards of Excellence and Hard Work. It’s fantastic to know the system is up and running and that you would happily use the Alliance crews again. We truly appreciate the recommendation. Mel - Alliance Climate Control
Mohamed and Ryan of Alliance Climate Control took care of the electrical needs of the installation and they were very efficient and worked well.

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.
Response from the owner:Dear Helen, Thank you for taking the time to share your feedback. We’re so pleased to hear you’re happy with the outcome. Aesthetics are incredibly important to us, so it’s great to know the team carefully routed the cabling to minimise visual impact while still delivering a high quality installation. We hope you enjoy the comfort of your new split system for many years to come. Thank you for trusting Alliance with your installation. Mel - Alliance Climate Control
Great service at a predictable firm cost. Friendly staff, everything explained well, and best of all the guys kept the job clean while working around a house of busy home office workers. Bonus points for making sure the dog didn't escape (and giving him pats). Thank you and we'll be back.
Response from the owner:Dear Rob, We really appreciate you sharing this, and your continued loyalty truly means a great deal to our team. We’re so glad you found the process clear and the pricing transparent from the start.

Re: Dais, Sayed & Christian
Hello,
I have been meaning to send this email for quite some time, but due to poor health, and lots of other excuses, I simply haven't gotten around to it.

I wanted to provide feedback for the above job number, as the boys really did work their arses off! It was a complicated job (which even I could see as a layman), and yet nothing was off-limits. They really did everything to accommodate the job, and my individual requests. As an individual, I am very particular and hold very high standards, and yet, they did not blink and eyelid.

I would also like to mention that all three of them were a delight to have in my home. It goes without saying, that they are a credit to your company, and it was an absolute pleasure working with them.
Kind regards
Lisa
Response from the owner:Dear Lisa, It was a pleasure to assist you with your installation, and we truly appreciate you taking the time to share such thoughtful feedback, especially given everything you’ve had going on. We’re so glad to hear that Qais, Sayed and Cristian made such a positive impression. Complex installations can certainly present challenges, but our team is committed to approaching every job with care, determination and attention to detail. It means a great deal to know they worked tirelessly to accommodate both the technical demands of the project and your individual requests without hesitation. We also value the way our team presents themselves in our customers’ homes. Being respectful, considerate and easy to have around is just as important to us as delivering a high standard of workmanship. Hearing that they were a delight to work with and upheld the high standards you expect is something we’re incredibly proud of. They truly are a credit to our business. We hope you’re now enjoying the comfort of your new system, and we’re always here should you need us. Mel - Alliance Climate Control
