Hesnor Engineering Associates

What Hesnor Engineering Associates does

Hesnor Engineering Associates (HEA) is a privately held mechanical, electrical, and plumbing (M/E/P) engineering design firm founded in 1992 by Thomas Hesnor, Sr. and organized as a Professional Limited Liability Company (PLLC). The firm operates from two offices in Albany, New York (headquarters) and Adams, Massachusetts, serving public, private, and institutional clients across the Northeast United States. HEA employs 11-50 staff and is led by partners TJ Hesnor, PE (managing the New York office with 25+ years of experience) and Mike Trzcinski, PE, CPD, LEED AP (managing the Massachusetts office with two decades of experience).

The firm's service portfolio spans core M/E/P and fire protection engineering design, supported by specialty capabilities including sustainable/LEED design, HVAC systems, data center design, controlled environment agriculture (CEA) for cannabis production, energy services, commissioning, BIM modeling, project management, code compliance, and construction cost estimation. Technical differentiators include deep specialization in occupied 24/7 facility engineering with sophisticated construction phasing plans that minimize operational disruption, specialized HVAC systems for high-latent-load environments such as cannabis cultivation rooms, and strict protocol compliance for security-sensitive institutional clients. HEA holds approved consultant status under multiple government term contracts, including MA DHCD's House Doctor Program (third consecutive term), NY SUCF, DASNY, ORDA, MA DCAMM, and MA DOS, providing recurring public-sector engagement opportunities.

HEA generates revenue through project-based professional service fees for M/E/P design, commissioning, equipment procurement, and construction administration, supplemented by recurring term-contract billings with government agencies. The go-to-market is sales-led and relationship-driven, securing engagements through direct proposals, government term contracts, and professional referrals from facility owners, architects, and institutional clients. Customer segments include K-12 education, higher education, public sector, commercial, healthcare, industrial + research, multi-unit residential, data centers, and cannabis production. Notable project outcomes include multiple LEED-Gold certified K-12 school renovations (Hoosac Valley, Granby Elementary, Colegrove Park), one of the first net-zero-energy-capable multifamily housing projects in Massachusetts (Highland Woods Senior Housing), and 2,300+ multi-family housing units designed in the last five years alone.
