What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. Too many air changes, however, can be detrimental because every time the air is replaced, it must be reheated or recooled, leading to higher energy use and lower efficiency. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home. A blower door test in Bedminster, NJ helps homeowners and builders find and fix leaks promptly, boosting energy efficiency and indoor comfort for years to come.

What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Bedminster, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.

Preparing for a Blower Door Test in Bedminster, NJ

To prepare a home for blower door test in Bedminster, NJ, we shut off the HVAC system and disable all exhaust fans. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. We’re equipped with chalk, spray foam, and weatherstripping materials, so we can partner with homeowners or contractors to repair visible air leakage problems right on-site. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Bedminster, NJ efficiency standards.
