Ductwork.
In-house sheet-metal fabrication, ductwork installation, modification, and air balancing for commercial HVAC projects.
At a glance
Ductwork at a glance
In-house fabrication
Duct sections, fittings, transitions, and plenums fabricated at the Huntington Station shop to project specifications.
Field-measured
Modifications are measured on site and fabricated to match existing systems.
Balanced after install
Air balancing verifies that each zone gets its design airflow.
Sealed and supported
Hangers, sealing, and insulation to the approved design and applicable codes.
Fabrication
Icebox operates a fabrication shop for custom sheet-metal ductwork. Duct sections, fittings, transitions, and plenums are fabricated in-house to project specifications. In-house fabrication allows Icebox to control quality, lead times, and fit-up accuracy for each project.
Shop to ceiling
From shop drawing to balanced airflow
Ductwork that is fabricated to the drawing but not to the building ends up with field-cut fittings, leaks, and rooms that never reach setpoint. Icebox surveys the ceiling cavity, checks beam and sprinkler clearances, and fabricates in its own shop from verified dimensions.
Installation includes hangers and supports, sealed joints, insulation where specified, and tie-ins to equipment. Once the system runs, air balancing measures and adjusts each outlet so the design airflow reaches every zone.
- Galvanized sheet-metal fabrication in-house
- Tenant build-out modifications and rerouting
- Equipment tie-ins and transitions
- Duct sealing and insulation
- Air balancing with documented readings
Installation
Icebox installs ductwork for new construction, tenant build-outs, and system replacements. Installation includes hangers, supports, sealing, insulation, and connections to HVAC equipment. All ductwork installation follows the approved mechanical design and applicable building codes.
Fire-suppression systems and fire-suppression-related ductwork are outside the scope of Icebox Mechanical Corp's services.
Modification & Rerouting
For existing buildings, Icebox performs ductwork modifications, extensions, and rerouting to accommodate tenant changes, equipment replacements, and system reconfigurations. Modifications are field-measured, fabricated to match existing system specs, and installed to maintain proper airflow throughout the system.
Air Balancing
Icebox performs air balancing to verify and adjust airflow distribution across duct systems. Balancing is performed after installation or modification to ensure each zone receives the airflow specified in the mechanical design. Proper balancing supports consistent temperature control and system efficiency.
Fire-suppression systems are outside the scope of Icebox Mechanical Corp's services. Icebox does not design, install, service, or modify fire-suppression systems.
