Job brief

We are seeking a detail-oriented HVAC Design Engineer to join our high-performing MEP engineering team and lead the design of complex climate control systems. You will take ownership of mechanical design projects, from initial feasibility studies through to final commissioning and operational handover. In this role, you will collaborate with cross-functional stakeholders to deliver energy-efficient, sustainable, and cost-effective HVAC solutions for our upcoming multi-million dollar developments. If you possess a deep understanding of thermodynamics and fluid mechanics and are passionate about innovative sustainable building design, we want to hear from you.

Key highlights

Perform complex heating and cooling load calculations to accurately size HVAC equipment and distribution systems for large-scale commercial structures.
Develop comprehensive mechanical construction documents, including detailed ductwork, piping schematics, and mechanical plans using Revit and AutoCAD MEP.
Ensure all system designs strictly adhere to ASHRAE, SMACNA, and local building codes, as well as NFPA fire safety and life-safety standards.
Select and specify high-efficiency boilers, chillers, AHUs, and VRF systems that align with project budgets and sustainability certification requirements.

What is a HVAC Design Engineer?

An HVAC Design Engineer is a specialized mechanical engineer who plans, designs, and optimizes heating, ventilation, and air conditioning systems for commercial and industrial facilities. Using advanced engineering software, an HVAC Design Engineer performs critical heat load calculations and psychrometric analysis to ensure building energy efficiency and indoor air quality. Their technical expertise is fundamental in transforming architectural schematics into functional, code-compliant mechanical systems that regulate climate control for diverse building portfolios.

What does a HVAC Design Engineer do?

A typical day for an HVAC Design Engineer involves performing precise heating and cooling load calculations using software like Carrier HAP or Trane TRACE 700 to determine equipment sizing. They develop detailed construction documentation, including ductwork layouts, piping diagrams, and mechanical equipment schedules using Revit or AutoCAD. They regularly interface with architects, electrical engineers, and plumbing contractors to resolve design conflicts, ensure compliance with ASHRAE 90.1 energy standards, and conduct field inspections to verify that installed equipment meets rigorous performance specifications.

Key responsibilities

Perform complex heating and cooling load calculations to accurately size HVAC equipment and distribution systems for large-scale commercial structures.

FAQs

What does an HVAC Design Engineer do?

An HVAC Design Engineer is responsible for designing the mechanical systems that control temperature, humidity, and air quality within buildings. They perform thermodynamic calculations, select mechanical equipment, and create the detailed blueprints (CAD/BIM) that contractors use to install heating, cooling, and ventilation hardware.

What software do HVAC Design Engineers use?

HVAC Design Engineers typically utilize Revit MEP for 3D building information modeling (BIM) and AutoCAD for 2D construction documentation. For performance analysis, they use specialized tools such as Trane TRACE 700, Carrier HAP, or IESVE to perform energy modeling and calculate heating and cooling loads.

How do you become an HVAC Design Engineer?

To become an HVAC Design Engineer, you typically need a Bachelor’s degree in Mechanical Engineering. Many employers look for candidates who have successfully completed the Fundamentals of Engineering (FE) exam and have gained hands-on experience with mechanical system design and building codes under the supervision of a licensed Professional Engineer (PE).

Why is an HVAC Design Engineer important for new construction?

An HVAC Design Engineer is critical because they ensure that a building is safe, energy-efficient, and comfortable for occupants. Their design choices directly impact a building's operational costs, carbon footprint, and adherence to complex life-safety codes, making them a vital link between architectural concepts and functional construction.
