Equipment Replacement & Projects

Complex HVAC systems rarely come with simple answers. Zeyman brings more than 20 years of union field and project leadership to evaluate each situation in full considering the equipment, the facility it serves, and the long-term impact of the work.

When manufacturer involvement is required, Zeyman serves as the customer’s technical advocate clearly defining the issue, coordinating directly with manufacturer technical teams, and keeping the facility’s operational and long-term interests at the center of the resolution.
