Duct airtightness testing

Duct airtightness testing measures how much air is leaking from your HVAC duct system and confirms that it meets applicable energy and building code requirements. Leaky ducts can significantly reduce system efficiency, increase energy costs, and compromise comfort—making testing an important step for many new construction and renovation projects.

Our Duct Airtightness Testing service helps builders, homeowners, and project teams verify that duct systems are installed correctly and performing as intended. Using calibrated testing equipment, we pressurize the duct system and measure air leakage to assess overall airtightness. The results can be used to demonstrate compliance with energy efficiency requirements, support energy modelling, or satisfy municipal and program-specific documentation needs.

Our process focuses on accuracy, clear reporting, and practical coordination with the construction schedule. We work alongside builders and installers to ensure testing is completed efficiently and that results are clearly documented.

Benefits of duct airtightness testing include:

• Verification of HVAC duct sealing and installation quality
• Support for BC energy and building code compliance
• Improved energy efficiency and system performance
• Reduced risk of inspection or occupancy delays
• Clear documentation for permitting and compliance records

Whether your project requires duct airtightness testing for compliance or you want confirmation that your HVAC system is performing efficiently, we provide reliable testing and straightforward reporting to support a successful build.
