You design and optimize the systems that keep buildings comfortable — air conditioning, heating, ventilation. You're calculating loads, selecting equipment, and solving the puzzle of moving air and heat where they need to go.
Your work centers on designing systems that move air and heat — sizing compressors, calculating thermal loads, selecting equipment, and solving the puzzle of keeping buildings comfortable efficiently. You're reading blueprints, running calculations, specifying ductwork, and sometimes troubleshooting systems that aren't performing. It's applied physics with real constraints — budget, space, code requirements, energy efficiency. You might spend a morning modeling humidity control for a hospital, then the afternoon reviewing contractor drawings. What's harder than expected: requirements conflict constantly — quiet, efficient, cheap — pick two. You need judgment. What helps you thrive: comfort with calculation and CAD, interest in systems thinking, and ability to navigate trade-offs with architects and facility managers.
