What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Barrington, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. 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?

Homes in Barrington, NJ are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally.

Preparing for a Blower Door Test in Barrington, NJ

To properly prepare for blower door test in Barrington, NJ, the HVAC system and all bathroom and kitchen fans are turned off. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining the thermal envelope. After sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Barrington, NJ building codes.
