If you're coming from the traditional HVAC (heating, ventilation, and air conditioning) world, you'll recognize a lot of this work. If you're coming from IT or construction, a lot of it will be new. But the core of the job is physical, technical, and practical. You're not sitting at a desk; you're on job sites, in crawlspaces, in mechanical rooms, and sometimes in a trench up to your knees in mud.
