2.1 Safe to install
This application, developed by the Sheet Metal and Air Conditioning Contractors’ National Association (SMACNA), offers a user-friendly yet efficient solution for estimating air leakage from ductwork. Designed for engineers, architects, designers, and contractors, this tool facilitates accurate assessments of ductwork leakage. It also simplifies the process of establishing pass/fail criteria for properly specified Duct Air Leakage Tests (DALT).
- Users can aggregate various ductwork sections of differing sizes and shapes to determine total allowable leakage.
- The application adopts the methodology detailed in SMACNA’s HVAC Air Duct Leakage Manual and incorporates suggested leakage classes from the latest edition of the manual.
- The methodology employed complies with ASHRAE 90.1, IECC, IGCC Version 2, IMC, and the UMC standards.

FAQ
What is DALC?
DALC stands for the HVAC Duct Air Leakage Class, which is a standard for measuring the air leakage in HVAC ductwork.
Who developed DALC?
DALC was developed by the Sheet Metal and Air Conditioning Contractors' National Association (SMACNA).
Why is DALC important?
DALC is important because it helps ensure that HVAC systems are properly sealed to prevent energy loss and maintain indoor air quality.
What are the different classes in DALC?
DALC has four classes: A, B, C, and D, with Class A having the lowest allowable air leakage rate and Class D having the highest.
How is DALC determined?
DALC is determined through testing procedures outlined in SMACNA's HVAC Air Duct Leakage Test Manual.
What are the consequences of not meeting DALC requirements?
Failure to meet DALC requirements can result in increased energy costs, decreased system efficiency, and potential indoor air quality issues.
Can DALC be improved in existing HVAC systems?
Yes, existing HVAC systems can be retrofitted to improve their DALC by sealing leaks and ensuring proper duct insulation.
Is DALC a mandatory standard for HVAC systems?
While DALC is not a mandatory standard in all regions, it is recognized as a best practice for achieving energy efficiency and indoor air quality.
