ESC of Central Ohio HVAC System Replacement & Server Room Cooling Upgrade

Prodigy provided engineering, labor, and materials to modernize the HVAC systems serving the first and second floors of the Educational Service Center of Central Ohio. The project included replacement of two large rooftop units, installation of a new split‑DX cooling system for the server room, zoning improvements, new VAV boxes with electric reheat, and full mechanical, electrical, and ceiling restoration work.

Two new 50‑ton cooling‑only rooftop units were installed to replace the existing equipment. Each unit features thermally broken double‑wall construction (R‑13), 20,000 CFM supply fans, 0–100% economizers with enthalpy control, plenum exhaust fans, MERV‑8 filtration, R‑32 refrigerant, four compressors with 4‑step capacity control, and low‑ambient operation down to 25°F. Factory warranties include one‑year parts and five‑year compressor coverage.

To improve reliability for critical IT infrastructure, Prodigy installed a 5‑ton Liebert split‑DX air handling unit dedicated to the server room. The system includes a variable‑speed EC fan, condensate pump, non‑locking disconnect, new rooftop condensing unit, and R‑410A refrigerant. The outdoor condensing unit is rated for operation down to ‑30°F and provides 40–100% digital capacity control. All equipment is fed from a new electrical panel installed in the server room.

To correct zoning issues and improve comfort, Prodigy installed nine new VAV terminal boxes—four single‑duct units and five parallel fan‑powered units with electric reheat. Work included duct modifications, new thermostats for each zone, relocation of up to ten existing thermostats, and removal/reinstallation of ceiling systems to accommodate new ductwork. All new and existing VAV boxes were fully rebalanced on both floors.

Additional services included furniture protection and movement, owner coordination for personal items, and phased scheduling to minimize disruption.

Prodigy also provided signed and sealed engineering drawings, secured all required permits, and managed site coordination and subcontractor oversight throughout the project.

This renovation delivers improved comfort, better zoning control, increased energy efficiency, and enhanced server room redundancy for the Educational Service Center of Central Ohio.
