We were very pleased doing business with Ultimate Air Conditioning and are repeat customers due to the quality of service we had from start to finish. Our technicians, Keahi and Levi, were top notch! They worked efficiently, were knowledgeable and friendly, and took time to review the setup with us. The AC unit we purchased direct from Ultimate Air appears to be top of the line. Mahalo Keahi and Levi for taking good care of us!

Much thanks to Ultimate Air Conditioning. Steve and his family went above and beyond for my ac install. Couldn’t be happier with my new unit. Love supporting hard working/honest local businesses like this. Will be recommending them to my family and friends. Best AC company on the island hands down!

Timely response as advertised on Yelp. Guys came earlier than expected in 3 days and cleaned the heck out of my split AC units that have not been cleaned in over 6 years — it was gross. Now my units are running like they’re brand new! Highly recommended!
