What Is A Blower Door Test?

A blower door test calculates the rate of air changes per hour in a property, verifying that proper ventilation keeps air fresh and clean. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced 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 Middletown, NJ helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Middletown, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. 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.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.

What Is A Passing Blower Door Test Score?

Preparing for a Blower Door Test in Middletown, NJ

Getting ready for blower door test in Middletown, NJ involves turning off all heating, cooling, and exhaust ventilation systems. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within the thermal envelope. Once everything is closed off, we set up the blower door fan on a centrally located exterior door and depressurize the interior to 50 Pascals to assess air leakage accurately. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Middletown, NJ.
