HEA provides mechanical, plumbing, and electrical engineering design services across industries that include Healthcare, Commercial, Multi-Unit Residential, Education, Data Centers and more. Engineering firms are hired for two things: their knowledge and expertise. Hesnor Engineering Associates (HEA) has the knowledge and expertise to deliver sound, experience-based, energy-efficient M/E/P engineering solutions. Many firms spend a lot of time talking about their client service philosophy. Ours is simple: we assess each project independently, deliver fundamentally sound designs, and implement them within budget and on schedule.
