Supply Duct
A supply duct is a crucial part of heating, ventilation, and air conditioning (HVAC) systems that delivers conditioned air throughout a building. Think of it like the roads that transport warm or cool air from the main HVAC unit to different rooms. These ducts are typically made of metal, flexible materials, or fiberglass, and they need to be properly sized, installed, and maintained to ensure efficient heating and cooling. When you see this term in resumes, it usually relates to installation, repair, or maintenance of these air delivery pathways.
