What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in Bay Head, NJ helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Bay Head, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. 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?

Houses in Bay Head, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. By meeting this standard in your blower door test in Bay Head, NJ, you can enjoy lower utility bills and peace of mind with code compliance.

Preparing for a Blower Door Test in Bay Head, NJ

Preparation for blower door test in Bay Head, NJ begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. Next, we conduct a quick walkthrough of the home, confirming that all exterior doors and windows are securely closed — including those to unfinished basements, garages, or any area outside the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. After the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. After all leaks are sealed, we retest immediately to confirm the desired blower door score has been met and that your home satisfies efficiency requirements in Bay Head, NJ.
