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.  Keeping with the tradition of quality workmanship at a competitive price, in 3 years, David has grown the company from 20 employees to over 40 employees including Engineers, building energy management services, licensed Sheet Metal Fabricators and Installers, licensed Plumbers, certified Welders, licensed Medical Gas Installers, and licensed HVAC Service Technicians serving Connecticut businesses.  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.

USA Mechanical & Energy Services continues to be a family business built on a reputation of dependable, quality and trusted service completing projects on schedule.  We are a full service mechanical contractor providing 24/7 HVAC Service & Maintenance.  We establish and value long-term partnerships with our customers who return to us to continue to help them solve problems at a competitive cost.
