When it comes to choosing the right ductwork for your home, there are a few factors to consider. Sheet metal ducts are the most recommended type of air ducts, since they are not porous and do not allow mold or bacteria to reproduce. They also help prevent potential health risks from fiberglass air ducts. Flexible ducts are a good option for adapting to small spaces, but they can be easily damaged during installation and can lead to air leaks.
Galvanized steel is strong, durable, and corrosion-resistant, and is widely used as a duct material. Rectangular ducts are more flexible when it comes to fitting in limited spaces, but they have a higher basic cost per pound than galvanized steel. Fiberglass ducts are insulated as part of their construction and are the easiest to install, but they can be easily damaged and can reduce airflow. Wood fiber ducting is often the most economical option, but it can trap dust and dirt and affect airflow. Choosing the right type of ductwork for your home depends on the materials, the overall design, your heat retention or noise reduction needs, and your budget.
It's also important to choose a contractor who has experience installing different types of ductwork. This will ensure that your home's HVAC system is operating efficiently and safely for years to come.
