What Is A Blower Door Test?

A blower door test calculates the rate of air changes per hour in a property, verifying that proper ventilation keeps air fresh and clean. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Weymouth township, NJ helps discover hidden leaks early so homeowners can save energy, enhance comfort, and improve home resilience.

What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Weymouth township, 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. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.

In Weymouth township, NJ, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. Meeting this benchmark in your blower door test in Weymouth township, NJ reduces ongoing energy costs while ensuring local regulatory compliance.

Preparing for a Blower Door Test in Weymouth township, NJ

Before conducting blower door test in Weymouth township, NJ, we make sure all heating, cooling, and ventilation fans are switched off. 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 all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Weymouth township, NJ energy efficiency codes.
