What Is A Blower Door Test?

A blower door test is designed to measure air changes per hour inside homes, promoting a balance between airtightness and necessary ventilation. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. Excessive air changes often cause drafts, discomfort, and humidity-related issues such as condensation and mold growth inside the home. A blower door test in Sea Isle City, NJ assists in finding and sealing air leaks early to improve home comfort, energy efficiency, and overall durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Sea Isle City, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure 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 Sea Isle City, NJ

Preparation for blower door test in Sea Isle City, NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. 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. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Sea Isle City, NJ building codes.
