Air Duct Calculators: How To Size A Duct System For A House

In this video I explain how I have used a ductulator to design a duct system for a house. This video is filmed to help fellow HVAC technicians learn industry standards for supply and how to size duct systems for homes. This is particularly helpful for the NATE Review Exam.

In this design we are working with a three ton system with 400 CFMs per ton which is the industry standard for supply. We'll also walk through the process of determining when and how to add more than one return to your system.

It's important to use the correct duct sizing in your design so that your unit is not over taxed, does not experience high amp draws and does not experience various issues with your air handler or compressor.

Thanks for watching!
