Hard Duct: ExplainedĪlso known as metal ducts, hard duct provides a more permanent solution to commercial HVAC system due to its rigidness. It is made of aluminum or galvanized steel, featuring a thick, solid wall that makes it incredibly durable. Inside this ductwork is where dust, as well as debris and other particles, are trapped. Yet, you don’t have to worry because the surface of such ducting material is smooth and generally easy to clean. Hard duct requires measurements, computerized design, as well as careful ductwork installation.īefore installing them, professionals consider the existing parts of the commercial building’s cooling and heating system, including the air conditioner, furnace, heat pump, and others.Īside from that, professionals also consider the width-to-height ratio in a commercial building. Flexibility – For current trunk-and-branch heating and cooling systems, flex ducts are safer.The Difference Between Flex And Hard Duct The reason is that hard ducts require space to optimize performance and energy efficiency. This is because they’re more versatile and functional. Owing to the design of steel, hard ducts are stronger. Price – Flex ducts are significantly cheaper than hard ducts.For this reason, they are suitable for constructing an entire HVAC system. Since hard ducts are made of galvanized steel or aluminum, the cost of transporting, creating, and installing them is higher. On the other hand, a hard duct is an expensive upfront expense for a commercial building, but it saves money – regardless of the outside environment – by ensuring high indoor air quality and controlling indoor temperature.
