What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Ocean township (Ocean), NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. 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. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home 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.

Preparing for a Blower Door Test in Ocean township (Ocean), NJ

To prepare for blower door test in Ocean township (Ocean), NJ, we start by turning off the heating and cooling system, along with all bathroom fans 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. Once all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into 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. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Ocean township (Ocean), NJ building codes.
