What Is A Blower Door Test?

A blower door test determines the air changes per hour of a house or building, ensuring proper ventilation as old air cycles out and fresh air flows in. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Fairfield township, NJ helps discover hidden leaks early so homeowners can save energy, enhance comfort, and improve home resilience.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Fairfield township, 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.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the NJ climate.

Preparing for a Blower Door Test in Fairfield township, NJ

To prepare for blower door test in Fairfield township, NJ, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. Next, we inspect each room to confirm all exterior doors and windows are properly closed — including any leading to garages, basements, or other spaces 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 the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to unconditioned areas. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Fairfield township, NJ efficiency codes.
