Duct leakage testing is a vital component in verifying the air-tightness of HVAC ductwork systems. It ensures compliance with energy codes, improves indoor air quality, enhances system efficiency, and reduces operational costs. This specification outlines the requirements for conducting duct leakage testing in accordance with industry standards.
2. ScopeThis document specifies the procedures, equipment, acceptance criteria, and documentation required for performing duct leakage testing on newly installed or existing HVAC duct systems. It applies to both supply and return air ducts in residential, commercial, and industrial buildings.
3. Standards and ReferencesDuct leakage testing shall be conducted in accordance with the following:
-
SMACNA HVAC Air Duct Leakage Test Manual
-
ANSI/ASHRAE Standard 215 – Method of Test for Determining Leakage of Operating HVAC Air Distribution Systems
-
ASTM E1554 – Standard Test Methods for Determining Air Leakage of Air Distribution Systems by Fan Pressurization
-
IECC (International Energy Conservation Code)
-
Project-specific specifications
All test equipment must be calibrated within 12 months prior to testing and include:
-
Calibrated duct leakage tester (blower door, duct blower)
-
Digital manometer (minimum accuracy ±1%)
-
Flow capture hood (if required)
-
Temporary duct sealing materials (e.g., tape, plastic)
-
Pressure tap and tubing
-
Seal all intentional openings: registers, diffusers, and grilles.
-
Inspect ductwork for visible leaks or damage.
-
Ensure ducts are clean and dry.
-
Close all access panels and dampers.
-
Connect the duct tester to the duct system through a designated port or removed grille.
-
Pressurize the system to the specified test pressure (typically 25 Pa or 0.1 in. w.g. for residential, up to 1000 Pa for commercial).
-
Measure leakage airflow in cubic feet per minute (CFM) at the target test pressure.
-
Record pressure differential and leakage rates.
-
Conduct at least two tests for verification.
-
Leakage ≤ 4 CFM per 100 ft² of conditioned floor area (post-construction test)
-
Leakage ≤ 3 CFM per 100 ft² (rough-in test with air handler installed)
-
Leakage Class defined per SMACNA based on pressure class and duct surface area
-
Allowable leakage rates calculated using the formula:
CL = (F × P^0.65) × (A / 100)
Where:-
CL = leakage (CFM)
-
F = leakage factor (Class A: 6, Class B: 3, Class C: 1)
-
P = test pressure (in. w.g.)
-
A = duct surface area (ft²)
-
Test reports must include:
-
Project name and location
-
Date and time of test
-
Tester’s name and certification (if applicable)
-
Equipment used (make, model, serial, calibration date)
-
Duct system description (location, type, area)
-
Test pressure and leakage rate (CFM)
-
Compliance statement (Pass/Fail)
-
Annotated duct layout (optional)

An AC Aluminium Grill is a component used in air conditioning systems to provide efficient air distribution and ventilation. It is typically installed at the outlet of an air conditioning unit or duct system to ensure that conditioned air is evenly distributed throughout a space. Here’s a detailed description of its features and specifications:
Description:1. Product Overview:
- Type: AC Aluminium Grill
2. Key Features:
- Material: Made from high-quality aluminium, which provides durability, resistance to corrosion, and an attractive finish.
- Design: Features a sleek and modern design that complements various interior styles while offering effective air distribution.
- Adjustable Louvers: Equipped with adjustable louvers or blades that allow for precise control of airflow direction, enabling customization of air distribution to meet specific needs.
- Easy Installation: Designed for straightforward installation, typically featuring mounting flanges or clips for secure attachment to ducts or air conditioning units.
- Maintenance-Friendly: Smooth surface and removable grille design facilitate easy cleaning and maintenance to ensure optimal performance and hygiene.
3. Specifications:
- Size and Dimensions: Available in various sizes and dimensions to fit different air conditioning units and duct openings. Common sizes include standard dimensions for residential and commercial applications.
- Finish: Often finished with a powder-coated or anodized surface to enhance durability, resistance to wear, and aesthetic appeal.
- Airflow Capacity: Designed to handle varying airflow capacities based on the size and requirements of the air conditioning system, ensuring efficient air distribution.
4. Applications:
- Residential: Used in homes for distributing conditioned air from central air conditioning systems or ductless units, enhancing comfort and airflow.
- Commercial: Suitable for offices, retail spaces, and other commercial environments where effective air distribution and a professional appearance are required.
- Industrial: Applied in industrial settings to ensure proper ventilation and air circulation in large spaces with high air conditioning needs.
5. Maintenance and Support:
- Maintenance Requirements: Regular cleaning is recommended to prevent dust buildup and ensure efficient airflow. The grille can typically be removed for easy access during cleaning.
- Support: Usually supported by the manufacturer’s warranty and customer service, providing assistance with product installation, maintenance, and any issues that may arise.
