What Is A Blower Door Test?

A blower door test is performed to identify the rate of air changes per hour, confirming your home receives a healthy exchange of fresh air. 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. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Roselle, NJ locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Roselle, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Construction in Roselle, NJ must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. In most jurisdictions, 3 air changes per hour or less is the benchmark for acceptable blower door test results and energy efficiency. By meeting this standard in your blower door test in Roselle, NJ, you can enjoy lower utility bills and peace of mind with code compliance.

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.

Preparing for a Blower Door Test in Roselle, NJ

Preparation for blower door test in Roselle, NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. With the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Roselle, NJ efficiency codes.
