What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. 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 Holmdel, 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?

When performing blower door test in Holmdel, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the NJ climate.

What Is A Passing Blower Door Test Score?

Homes throughout Holmdel, NJ are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Passing this threshold during your blower door test in Holmdel, NJ ensures both energy savings and full compliance with local regulations.

Preparing for a Blower Door Test in Holmdel, NJ

For blower door test in Holmdel, NJ, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust fans. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces outside the thermal envelope. Once all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Holmdel, NJ energy efficiency codes.
