What Is A Blower Door Test?

A blower door test helps calculate air changes per hour in your property. This natural air exchange process refreshes the indoor environment with new air. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Hanover, 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?

For blower door test in Hanover, NJ, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. 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.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under NJ weather.

What Is A Passing Blower Door Test Score?

Homes throughout Hanover, NJ are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators.

Preparing for a Blower Door Test in Hanover, NJ

We begin blower door test in Hanover, NJ by switching off the HVAC system and shutting down all exhaust fans throughout the home. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve the thermal envelope. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Hanover, NJ building codes.
