Sizing duct work on your own can be a tedious and complicated task. Sometimes it’s best to leave it to a ductwork replacement company to get the most accurate sized duct work that works perfectly with your central AC unit and furnace to regulate home temperatures efficiently. You need to know the following: 

• Square footage of your home. 


• Square footage of each individual room in your home. 


• Cubic feet per minute calculations (explained below.) 


• Duct’s Sizing Friction Loss Rate 

HVAC systems work a lot more efficiently when the ductwork you use is the right size for your home. Install duct sizes that are too small, and your system will have to work harder to keep your home heated and cooled. If your duct sizing is too big, the velocity will be compromised, meaning you may not be able to feel it through the air vents.
