About Us



My name is Devin Ruiz. I’m the owner and founder of Smart AC Systems. I’m one of the early pioneers in Hawaii during the solar PV (photovoltaic) revolution and through my other company, Solar Training Institute, a State of Hawaii certified company, we trained contractors and individuals entering the growing solar industry. We trained hundreds of workers across Hawaii to safely and properly install quality solar systems and provided the highest certifications in the solar industry. Then in 2012 under the name STI Solar we started installing solar panels on Oahu, and later on Kauai, and eventually air conditioners.

The experience with air conditioning drove me to start a new company called Smart AC Systems. And in 2020, we became the fastest growing air conditioning company in Hawaii through a contract to install almost 800 Daikin split air conditioners at a large resort in Princeville, Kauai, which is part of the largest vacation ownership resort management company in the world.

Today, Smart AC Systems is an innovative, local air conditioning company that uses control technology and software to manage and maintain air conditioners for maximum performance remotely.

Our employees and technicians are trained in solar, air conditioning, and smart technology with a focus on continuous training and customer service. We desire to use our skills to provide energy-efficient air conditioning systems to better our Hawaii community and environment.
