BAS Design Engineer — Commercial HVAC Controls

Picture your morning at Airco Mechanical in Round Rock or San Antonio: coffee in hand, contract set open, scoping a new building automation package that will keep a campus running smoothly through Texas heat. You translate specs into clear plans, balance performance with budget, and make sure every component plays well together. By afternoon, your Visio riser is buttoned up, the network architecture is clean, and your submittal tells the story of a system that just works.
