Commercial HVAC Design.
Load calculations, equipment selection, and mechanical design coordination for commercial projects. The architect operates independently under their own seal.
At a glance
Design coordination at a glance
Load calculations
Heating and cooling loads calculated for the actual building, occupancy, and envelope, not rules of thumb.
Equipment selection
Selections from all major manufacturer lines, matched to the load, the available electrical service, and the roof or mechanical room.
Duct and piping layout
Routing planned around structure, ceilings, and other trades so it can be built as drawn.
Architect-aligned
The architect operates independently under their own seal. Icebox provides the mechanical coordination that supports it.
Design Coordination Scope
Icebox coordinates the mechanical design process for commercial HVAC projects. This includes performing heating and cooling load calculations, selecting equipment from the appropriate manufacturer line, laying out duct routing and system configurations, and coordinating with the project architect and engineer to align the mechanical scope with the overall building design.
The goal of design coordination is to produce a complete mechanical scope that can be executed cleanly during installation, with equipment properly sized and positioned for the building's operational requirements.
Design that installs cleanly
Design coordination that installs cleanly
The purpose of the design phase is an installation with no surprises: equipment that fits through the freight door, ductwork that clears the beams, refrigerant runs within manufacturer limits, and electrical loads the building can actually supply. Icebox brings the field perspective into the design package early.
Coordination runs through the project architect and engineer of record, who operate independently under their own seal. Icebox contributes load calculations, selections, and layouts, and stays engaged through submittals so the approved design and the installed system match.
- Heating and cooling load calculations
- Equipment selection with lead-time and access checks
- Duct, piping, and refrigerant-line routing
- Submittal and shop-drawing coordination
- Field verification before fabrication
What Icebox Handles vs. What the Architect Coordinates
Icebox Handles
- Heating and cooling load calculations
- Equipment selection and specification
- Duct layout and system configuration
- Mechanical coordination with the project team
- Equipment procurement coordination
Architect Coordinates Independently
- Sealed and stamped drawings under their own professional seal
- PE and RA professional services under their own license
- Final sealed-document delivery directly to the client or AHJ
- Code review and compliance sign-off under their professional responsibility
The architect operates independently under their own seal and professional license. Icebox does not provide PE or RA professional services directly.
Sealed-Document Delivery
Sealed and stamped construction documents are delivered by the architect directly. The architect operates independently under their own seal and is solely responsible for the content, accuracy, and delivery of sealed documents. Icebox provides the mechanical design coordination inputs that support the architect's work but does not produce, stamp, or deliver sealed documents.
What the design package typically covers
- Packaged rooftop units
- Split and VRF systems
- Air handlers and fan coils
- Dedicated outdoor-air systems
- Exhaust and make-up air
- Ductwork and diffuser layout
- Refrigerant piping
- Controls points and sequences
Icebox is not an authorized dealer, distributor, or agent of any manufacturer.
