About Us

Au's Extinguisher Service was founded in January of 1935 by Harry Au. After 40 years of running the business he passed it on to his son, Victor Au, who then took over it for 36 years. In January of 2012 Au's Extinguisher Service, Inc. came to be and is currently run by Derick and Aimee Au.


We are aware that there are always new advances in fire protection technology as well as testing methods. For this reason we are constantly continuing our training and education with recognized fire protection organizations to expand our knowledge.


Over the years our small family business has grown to become one of the oldest and well respected fire safety companies in Hawaii. Here at Au's Extinguisher Service, Inc. we will personally work with you to achieve fire code compliance.
