Charles and Aden from Alliance Climate Control have demonstrated exceptional work ethic and professionalism.
From a courtesy call, to his arrival, Charles provided a clear explanation of the procedure to identify the issue and rectify the electrical problem. I was particularly impressed by their continued diligence in locating the problem.
I have hesitation in recommending Charles and Aden and of course your company,

Kind regards
Peter & Michelle
A terrific job. Took great care in doing all that was required and left the place clean and tidy afterwards. Polite and respectful team. We are enjoying having aircon finally!
Jason was extremely helpful fixing our aircon unit. Arrived on time and kept me updated with his whereabouts, he diagnosed the problem quickly and completed the repair efficiently. My AC is running perfectly now - highly recommend.
We have high regard for the whole interaction that we had with Alliance Climate Control personnel. Aysa helped us to make our informed choice with the ac system that the technicians installed. Aysa is very friendly, courteous and knowledgeable. The technicians, Yunus, Can and Carlos, were very punctual and called us in advance to let us know of the time they will be coming. Their advice, workmanship and attention to detail were amazing. We take this opportunity to thank Yunus, Carlos, Can and Aysa and the supporting staff from the office, Luke and Cara. 👍👍👍

I couldn't be happier with the excellent service and clean provided by Emre.
He was punctual, thorough with his assessment of my aircon units and managed to identify the source of why my aircon has a mouldy smell. He was professional, knowledgeable and clear with his explanation of what can be the problems as well as recommending appropriate options to address the problems.
5/5 will call upon his services again if my aircons ever give me grief (though I doubt it with the level of servicing he performed).
Response from the owner:Dear Sky, Thank you for your 5-star rating and for taking the time to share such detailed feedback about your experience with Emre. His punctuality, care in assessing your system and ability to pinpoint the cause of the mouldy smell reflects the high standards and values we aim to deliver with every service visit.

Gokhan and Louis did an amazing job installing my air conditioner! We had them install a split system in our bedroom, and couldn’t be happier

Their communication was excellent - explained the whole process and were very helpful and accommodating. The little things like helping to test different power mains to find the best configuration, the care they took to cover up and move my furniture, and the spotless cleaning job they did afterwards really set them apart. They even gave us a small gift bag at the end, which was a nice touch.

Highly recommended to go with this company, they are professionals through and through!
Response from the owner:Dear James Your feedback means a great deal to our team, and it’s wonderful to hear how impressed you were with Gokhan and Louis throughout your installation.
