A blower door test measures how many air changes per hour occur in your home, ensuring fresh air circulation and improved indoor air quality. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Somerdale borough, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. 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.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the NJ environment.

Preparing for a Blower Door Test in Somerdale borough, NJ

Getting ready for blower door test in Somerdale borough, NJ involves turning off all heating, cooling, and exhaust ventilation systems. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside the thermal envelope. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. Our team brings chalk, spray foam, and weatherstripping supplies to every job, enabling us to collaborate with homeowners or contractors to seal visible air leakage areas immediately. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Somerdale borough, NJ building codes.
