Free iPhone App Estimates Air Duct Leakage -Image

A free app from SMACNA the Sheet Metal and Air Conditioning Contractors’ National Association, allows contractors, engineers, architects, and designers to easily and accurately estimate the leakage of air from ductwork.

The free app, for iPhone, iPad and iPod Touch, also provides a quick way to determine the pass/fail mark for properly specified duct air leakage tests (DALT) and generates a report that can be e-mailed directly from the app.

Users can combine multiple sections of ductwork that vary by size and shape to calculate total allowable leakage. The app uses the methodology found in SMACNA’s “HVAC Air Duct Leakage Test Manual,” 2nd edition, and provides applicable leakage classes from the publication’s latest edition. The method complies with ASHRAE 90.1, IECC, IGCC Version 2, IMC, and the UMC.

Anyone can access the tool by going to http://www.smacna.org/dalt.

Search the iTunes store using key words “SMACNA,” “HVAC,” “DALC,” “DALT” or “duct leakage” and download the app free of charge. Send feedback and questions to iTunes.
