A classic

This app has been around for years, and I finally got around to rating it. I use it daily and it's all i can ask for a simple duct sizing app. I love the emailing capability. Sure beats a ductulator. Love it!

Great update

I find I use this daily for doing rule-of-thumb duct calcs. Results appear accurate and it's good to see periodic updates coming out. I'd love to see a native iPad version developed, too.

high quality accuracy.

Very accurate and useful. Relatively easy to use if you know how to properly size ducts. The only problem with the app is after you enter a value, the screen stops scrolling up and down so you can't see the results. You have to back out to the main menu then re-select the category (i.e. Size by airflow) to see the answer.

A classic

I’ve had this app for 4 or 5 years now, and I can’t believe how use it still is. It’s great that Carmel keeps updating it and now I can use it on my iPad.

Great duct sizer

I’m an HVAC engineer and I use this at work almost every day. It’s a great way to quickly size a run of duct and easily switch between duct types.

Works great on my old iPod touch

I downloaded it on my old iPod touch (2 years old, I think). Anyway, it works great. I find that this app are a godsend; it is convenient to use, so that I do not have to run to the nearest computer every time I need to estimate duct sizes or velocity flow. Keep them coming!

Good app, needs iPod touch support

I bought this app for my iPhone. Very handy and good for duct sizing in the field. Next iteration might want to tabulate duct runs for friction loss. I hope the author of the program reviews the abilty for it to load on an iPod touch. When I tried to buy it for the touch it said that the application won't work on the touch because it needed a microphone. Unless there is a sound or db meter application I don't see why this is the case.I also bought the sister app for pipe siZing. Good little app also, hope the author continues to write and develop software for HVAC. Maybe pyschtometric app?

Happy so far, but.....

My only complaint is that there is no rectangular to round duct conversion function. This would be extremely helpful to me. Other than that I am pleased with the app.

Works great.

You should see the eyes of an engineer when I pull out my phone and use this app to show him that I can change the size of his duct correctly because of a beam the engineer "missed" when designing the system. The best is when I go into a home and show the owners why my competitor installed too small of ductwork for their top of the line a/c unit.

HVAC Design & Sales

This is the most useful app I have on my phone, as my profession is designing HVAC systems. The app is intuitive, versatile and functional. It fits in my pocket. It's accurate. I use it every day.

Description

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 iPad. Tens of thousands of happy users have downloaded this useful application for performing quick and simple duct sizing analysis.

The HVAC Duct Sizer is a universal duct sizing app so that it works on both the iPhone and iPad and adjusts its screen size accordingly. This app includes the HVAC Equipment Locator. Click here for details: http://bit.ly/1BPl1Nr Just a couple of comments from our users: "I'll be presenting your iPhone program to my HVAC class as an easy compact tool to have in hand when making sales and service calls." - R. Black "I like this app and use it daily" - V. Joe The 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.
