HVAC Engineer
Design heating, ventilation, and air conditioning systems for comfort and indoor air quality.
What HVAC Engineers Do
HVAC engineers design the systems that control building temperature, humidity, and air quality. This includes heating systems (boilers, heat pumps, furnaces), cooling systems (chillers, DX equipment, cooling towers), air distribution (ductwork, diffusers, VAV boxes), and ventilation per ASHRAE 62.1.
A core skill is performing Manual J load calculations for residential projects and detailed block/zone load calculations for commercial buildings. HVAC engineers use software like Carrier HAP, Trane TRACE, or eQUEST for energy modeling and equipment selection. They coordinate closely with electrical engineers for power requirements and with controls engineers for building automation.
Specialties within HVAC engineering include central plant design (large chiller/boiler plants), cleanroom HVAC (pharmaceuticals, semiconductors), data center cooling, and industrial process ventilation. Energy efficiency and sustainability are increasingly important, with net-zero building standards driving innovation in heat recovery, geothermal systems, and VRF technology.
