Our Story
The Origins of Total Home Calculations
Hi my name is Scott Gervais, I am 38 years old and have a passion on building companies and helping out others. I grew up in the construction world and started plumbing when I was just a kid helping my dad. This led to me going to college and getting a degree in architectural engineering. I have also obtained my plumbing license and HVAC certifications. With all of this I partnered with my brother Jeff and we built a 14-million-dollar HVAC company that we ended up selling so we can pursue other passions in life. Outside of work I have 2 kids and been married for 13 years. We enjoy camping and going to good restaurants just to relax.
