NY Air Leakage Test provides professional blower door testing and Duct leakage testing services for residential and commercial buildings throughout New York City and the surrounding areas. We help contractors, architects, developers, and building owners meet NYC Energy Conservation Code requirements — on time and on budget. 

 A blower door test measures how much air leaks through your building envelope — walls, windows, doors, and penetrations. It is one of the most important energy code compliance tests required for new construction and major renovations in New York City.

We test to:

• ASTM E779 — Standard Test Method for Determining Air Leakage Rate by Fan Pressurization

Results are reported in:

• CFM50 (Cubic Feet per Minute at 50 Pascals)
• ACH50 (Air Changes per Hour at 50 Pascals)

A detailed written report is provided within 24–48 hours of testing — suitable for submission to the NYC Department of Buildings (DOB).

•  General Contractors — meeting NYC Energy Code compliance for new construction
• Architects & MEP Engineers — verifying building performance meets design specifications
• Developers — ensuring projects pass inspection without delays
• Homeowners — identifying air leakage issues causing high energy bills
• Building Owners — improving energy efficiency and indoor comfo
