Enhancing Results

Our Approach

Mechanical engineering is the core competency on which Wood Harbinger was founded and remains a passion in our practice today.

We emphasize operational resiliency, system integration, and energy efficiency. We focus on optimizing environments for comfort, humidity and temperature control, and ventilation to support the needs of various spaces and the overall user experience. We prioritize client communication so that they understand the issues clearly and can make informed choices.

We take our responsibility seriously and assure that the tremendous trust placed in us rewards clients with systems that will work, on time, on budget, with a positive experience for all involved. Collaboration is the keystone of our culture.
