HVAC Engineer
Creating comfortable, efficient, and sustainable indoor environments.
What is a HVAC Engineer?
HVAC engineers design, develop, and oversee the installation and maintenance of heating, ventilation, and air conditioning systems. They analyze building requirements, select appropriate equipment, and ensure systems comply with energy efficiency standards and building codes. They also troubleshoot system malfunctions and optimize performance.
An HVAC engineer’s day mixes desk-based design with targeted site visits: computing load and water or air flow rates, checking plans in CAD, inspecting project sites against specifications, and coordinating with contractors by e-mail and phone. You’ll test soils or materials when rooftop units or foundations are involved, prepare technical advice for repairs or installations, and write the reports that feed permits and closeouts.
