HVAC Duct Sizer voted favorite mobile app by readers of Contracting Business magazine.The HVAC Duct Sizer app is the #1 selling duct sizing application for the Apple iPhone and now iPad. Thousands of happy users have downloaded this useful application for performing quick and simple duct sizing analysis. The HVAC Duct Sizer is the only universal duct sizing app on iTunes meaning this app works on both the iPhone and iPad and adjusts its screen size accordingly.This app now includes the HVAC Equipment Locator.

Black'I like this app and use it daily' - V. JoeThe Duct Sizer application allows you to quickly size one HVAC duct run or a range of duct sizes using the constant friction method. Think of this application as a digital version of the classic Trane Ductulator. In the 'Size by Airflow' mode, you can specify the total airflow in CFM (or L/s), the aspect ratio and one of either the velocity of air or the friction loss per 100 feet (30 meters). The results include both the exact and rounded height and width (or diameter) dimensions and the calculated velocity and friction loss.In the 'Size by Dimensions' mode, you can analyze an existing duct system. There are options to input the existing duct dimensions and one of either the airflow or velocity values to derive the calculated duct friction loss.In the 'Range of Duct Sizes' mode, you can specify minimum and maximum friction loss and airflow values to display a range of duct sizes that fall in between the friction loss bounds.You can specify additional parameters such as the duct shape (rectangular, round, or oval), the air temperature and the air pressure. You can also choose to display values in either English (IP) or Metric (SI) units.This application uses slider controls that allow you to quickly increment or decrement the input values and immediately observe the calculated results. This app now works on your iPhone and iPad and adjusts its screen size accordingly.Finally, you can email all of the inputs and results from all 3 input modes to perform further analysis using your desktop computer. The email includes HTML text and a .CSV attachment that can be imported into any popular spreadsheet.The 'HVAC Duct Sizer' application was designed by Carmel Software Corporation, a leader in HVAC design software since 1995. In fact, Autodesk (the makers of AutoCAD) acquired our load calculation software and incorporated it into their leading 3D modeling software called Revit. In addition, we developed a number of customized apps for ASHRAE, DNV GL, and other organizations.This app now includes the HVAC Equipment Locator which allows you to keep track of all of your equipment and store it in the cloud.
