What Is A Blower Door Test?

A blower door test evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. 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 Buena borough, NJ helps spot air leaks before they worsen, improving efficiency, comfort, and long-term structural quality.

What Our Clients Say

How Is A Blower Door Test Conducted?

To conduct blower door test in Buena borough, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

Preparing for a Blower Door Test in Buena borough, NJ

Getting ready for blower door test in Buena borough, NJ involves turning off all heating, cooling, and exhaust ventilation systems. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other 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. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to unconditioned areas. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Buena borough, NJ efficiency standards.
