Excellent
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.
Fantastic service. We had a bit of a difficult job and they came in with ease, no issues, job done. Very pleased !
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.
Very happy with Alliance. Thorough, professional and reliable. The electrician who came to my home was a great problem solver too
Response from the owner:Dear Penny, It was a pleasure to assist you with your air conditioning. Thank you for your kind words and 5 Star Rating! Mel - Alliance Climate Control

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.
Response from the owner:Dear Oz Butterfly, Thank you for taking the time to share such a thoughtful review of your experience. Complex installations such as multi split systems in strata units can certainly present challenges, so it’s fantastic to hear that the team worked together to make everything fit seamlessly and keep the day hassle free for you. We know how important it is in smaller spaces to leave everything exactly as we found it, so we’re pleased the team ensured everything was cleared away and returned to its place at the end of a long day. We’re also glad Kathrine and Luka made the process smooth from the office, clear communication and coordination are key to delivering the right outcome and long term comfort in your home. Thank you for choosing Alliance for your heating and cooling. We hope you enjoy the comfort of your new system for many years to come. Mel - Alliance Climate Control
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.
Response from the owner:Dear Dimitri, Thank you for your thoughtful and detailed review, we really value you sharing your experience. We’re so pleased to hear our technicians were polite, respectful and thorough during their visit.

Great service experience. I needed indoor LEDs and pendants and power points replaced, as well as some outdoor lights. Josh provided a quote and Peter and TK did the work.

Totally impressed by Alliance. The communication was very good and the technician (Kody) was personable, professional and most helpful.

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
