Duct Calculator Elite

Excellent app, but you guys need to add m3/hr this is the only reason I don’t give you 5 stars

When sizing based upon airflow, the result gives random fractional duct sizes like 5.3 x 9.6; doesn’t allow even numbered duct sizes. Pretty worthless to me, even if it were free.

For $6.99 this app is not worth purchasing. It leads you to believe it will help you solve duct size airflow problems. IMHO, it is not worth purchasing.

When using on a system that was sized corectly per ACCA or whatever load calc program your country uses its spot on

Doesn’t work. Rip off. Placed it my iphone max, strong internet doesn’t work !

This hvac app is the best by far. I was debating the price tag at first but am very happy with the purchase.

The best I have used and that's several. I only use this one now, so easy. Thank you very much.

Go to a ductulator , it's far better !!!!

By far the best duct calc. Extremely easy to use. I absolutely love this thing.

This is much easier than the sliders to enter the exact values I want....use it all the time...A+ Well worth the money!
