One thing to keep in mind is that in a typical house, about 20% to 30% of the air that moves through the duct system is lost due to leaks, holes, and poorly connected ducts. Often times, this is due to poor system configuration, which is a symptom of rectangular ducts.
Americans love their comforts. They don’t want to be too warm or too cold, preferring to toe the line between the two as much as possible. That is why so many homes have some form of air conditioning or heating units, depending on where the individual or family lives.
The air ducts in your home provide a very simple, yet important purpose. They’re responsible for temperature control in your house by cycling air through various vents. And it could be easy to assume that after the sheet metal fabricators have installed them and done their job, you never have to worry about them again.
Duct fabricators are having a bit of a moment. While builders have always required ducts for their buildings, until recently these features were tucked away behind walls and drop ceiling panels. Now, modern designers are incorporating exposed oval and spiral ducts and pipes into some of their hippest projects.
