What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Lyndhurst, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. 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 built in Lyndhurst, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect.

Passing this threshold during your blower door test in Lyndhurst, NJ ensures both energy savings and full compliance with local regulations.

Preparing for a Blower Door Test in Lyndhurst, NJ

For blower door test in Lyndhurst, NJ, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust fans. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond the thermal envelope. With all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Lyndhurst, NJ efficiency standards.
