Value Delivered

Heritage Mechanical Services installed a cutting-edge HVAC system for the new, 371-bed Coney Island Hospital. 

The system was designed to promote energy efficiency and provides precisely controlled conditions for multiple environments, including a pharmacy, labs, operating rooms, MRI rooms, patient rooms, and more. 

Client Objectives

Our client set out to construct a world-class, state-of-the-art hospital in an effort to attract top notch doctors and generate new jobs for the community. The new hospital will help expand healthcare options in an area previously devastated by Hurricane Sandy. 


Working as the air side mechanical contractor, we delivered a range of HVAC and sheet metal solutions, including furnishing and installing more than 250 tons of ductwork. 

The completed system featured:

  • Welded stainless steel exhaust systems
  • Double and single wall galvanized duct for supply and return
  • Rooftop double-height steel duct supports
  • Domestic water heater
  • Steam boiler and dual fuel boiler flues
  • HEPA filtration
  • 30 fans with variable frequency drives and starters
  • 68 chilled beams
  • 489 variable air volume boxes
  • 22 staged air volume units including eight with duct humidification
  • 14 reduced air volume units
  • Six exhaust air valves
  • Two air curtains
  • Four cabinet unit heaters 
  • Seven air handling units including two with heat recovery wheels
  • Two cooling towers
  • Two horizontal and vertical units
  • 19 fan coil units
  • 17 computer room air handling unit

Completing the roof ductwork and support steel was a major challenge because it needed to be installed 15 to 20 feet above the slab, requiring our team to work closely with crane crews. Altogether, over 100 crane picks were required, conducted over the course of a week, in order to get all the equipment set.
