The company was founded in 2003 by Larry Fontaine.  Prior to starting U.S.A Mechanical, LLC, Larry was the Construction Sales Manager and a member of the Board of Directors for New England Mechanical.  Larry specializes in design-build HVAC projects for clean rooms, environmental chambers, laboratories, commercial office space, retail, industrial, manufacturing and universities.  In 2017, David Ford purchased U.S.A. Mechanical, LLC from Larry Fontaine and renamed the company USA Mechanical & Energy Services, LLC. On November 14, 2019, USA Mechanical & Energy Services celebrated their grand re-opening ribbon cutting event undergoing a complete renovation and expansion of the office, warehouse and fabrication shop to over 10,000 sq. ft.

The company partnered with Astra Service Partners in 2021 and is now part of a network of leading mechanical service companies that perform essential services to keep America running. With our People-First approach, our aim is to foster an environment in which the best talent can excel, grow, and call home. Keeping with the tradition of quality workmanship at a competitive price, in just under 2 years, USA has grown by close to 30 employees, nearly doubling our staff in that time. In January 2023, Steve Dion took over as the new President of USA Mechanical, since then, Steve has been working hard to continue growing USA.
