Commercial & Industrial

From the Founder

"I found joy in making things work at an early age. As I began my career path in the HVAC industry, I quickly realized that I had chosen the right profession. Then, as I progressed in my career, I discovered that I was just as passionate about customer service as I was about mechanical systems. This desire to repair and serve culminated in the creation of Riggs Mechanical in 2020. With the addition of Chris Higginson as a partner in 2023, Riggs Mechanical has been rebranded as ProTherm Mechanical Contracting Inc -- and the future has never looked brighter!"
