J.W. Marriott Essex House
The retrofit of the HVAC systems at the iconic 44-story, 509-room J.W. Marriott Essex House hotel and residence in Manhattan exemplifies both the expertise of our staff as well as its ability to complete all aspects of a major HVAC project. Working for Marriott, we installed two 700-ton centrifugal chillers and two 3000-gpm cooling towers, as well as new pumps, filtration systems, air conditioning equipment and VFDs. As the project’s Prime Mechanical Contractor, the scope of work required us to also manage all demolition, rigging, sitework, structural, architectural, plumbing, automatic temperature controls, and electrical. The facility’s entire HVAC chilled water plant and system was taken off-line and put back in full operation only three months after construction started.
