HVAC Mechanical Designer

Summary

New England Tech Air Inc creates air systems for healthier environments in schools, hospitals, labs, and other facilities. The HVAC Mechanical Designer will design complete air systems from airflow and load parameters, including ductwork routing, system layouts, and equipment selection. The role also coordinates with other trades, produces construction documents, and partners with engineers and clients during preconstruction.

Responsibilities

• You start with the airflow and velocities the project calls for, then build the ductwork routing, the system layout, and the equipment selection from scratch. No tracing off an existing model
• You size the duct, set the volumes and capacities, and pick equipment against the parameters the engineer of record hands over on day one. When a client questions the finished design, the numbers behind it hold up because they are yours to defend
• The load calculations arrive complete from someone else. You translate those numbers into a full air system inside the model, sizing duct and laying out routing so the design carries every capacity the calc outputs specify
• The translation is exact. A finished calc set always has a matching, buildable air system design behind it that the project team can trust
• You coordinate with the electrical, plumbing, and architectural teams so routing and space conflicts get resolved on screen, not on the job site. Multi-trade drawings get reviewed and integrated so the air system fits the space it shares
• When a collision can reasonably be cleared, you clear it. When it cannot, you escalate to the general contractor with a specific ask. The field crew installs to a model that already accounts for everyone else in the building
• You produce complete construction document sets the shop and the field build from directly. Every set reflects the final air system design, the resolved trade coordination, and the sizing decisions behind it
• The documents are accurate enough that the people building from them do not have to re-check the work or chase gaps. A finished set tells the shop and the crew exactly what the air system is and how it fits
• You work directly with the engineer of record and the client through preconstruction. You attend design meetings and help shape the air system before it is locked in. You assist with equipment selection alongside the preconstruction and project management team, and you independently size and lay out air systems in partnership with the client
• This includes travel, averaging about one in-person meeting a month. The client sees us as a design partner, and the air system that comes out of those meetings is one everyone agreed to and can build

Skills

• 3 to 7 years of HVAC design experience on commercial and industrial projects
• A background in sheet metal design
• Proficient in AutoCAD for air system design and construction document production
• Proficient in Revit for air system modeling
• A working command of airflow, capacities, loads, and duct sizing at a level that holds up to client scrutiny
• Experience selecting HVAC equipment against design parameters and project requirements
• Experience coordinating routing and space with electrical, plumbing, and architectural trades
• Comfortable working directly with an engineer of record and a client through preconstruction
