What Is A Blower Door Test?

A blower door test determines the air changes per hour of a house or building, ensuring proper ventilation as old air cycles out and fresh air flows in. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing 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 Brooklawn, NJ identifies air leakage issues before they become serious, ensuring efficiency, comfort, and long-term durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Brooklawn, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Homes built in Brooklawn, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Achieving this standard in your blower door test in Brooklawn, NJ lowers utility bills and guarantees adherence to local code requirements.

Preparing for a Blower Door Test in Brooklawn, NJ

Preparation for blower door test in Brooklawn, NJ begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond 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 pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Brooklawn, NJ.
