When it comes to selecting the right ducts for your home or business, there are a few key differences between metal and flexible ducts that you should take into account. Metal ducts are rigid and provide superior air flow, while flexible ducts are easier to install and more cost-effective. However, opinions vary widely on which type of duct is best for your needs. Metal ducts are rigid and require precise measurement and adjustment during installation. They are more durable than flexible ducts, and can help reduce energy bills in areas like George, Utah, since the furnace and air conditioning unit won't have to work as hard to supply air to the entire building.
However, metal ducts can be exposed to a highly corrosive (rust-producing) environment, which can reduce their lifespan. Flexible ducts are significantly easier to install than metal ducts. They are lightweight and can be folded, making installation much faster and reducing labor costs and downtime. Flexible ducts come in a variety of materials that adjust to the shape of the building as needed, such as rubber, stainless steel, silicone, and polyurethane. However, flexible ducts can be easily pierced with any sharp object, and they can be deformed in such a way that it makes it difficult for the supplied air to reach the designated ventilation hole in the roof. In addition, each time a metal duct rotates, there will be two more seams, one at each end of the elbow.
Less experienced contractors may also arrange flexible ducts in complicated configurations with sharp curves and sections that sag under their own weight, reducing air flow at the far end of the flexible duct. In conclusion, both metal and flexible ducts have their advantages and disadvantages. Metal ducts provide superior air flow and are more durable, while flexible ducts are easier to install and more economical. Ultimately, it's important to consider your specific needs when deciding which type of duct is best for your home or business.
