What Is A Blower Door Test?

A blower door test evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing 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 Merchantville, NJ helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Merchantville, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. 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 extracts air, exterior air begins entering the house through any unsealed spaces or cracks. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in NJ.

What Is A Passing Blower Door Test Score?

In Merchantville, NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. Reaching this target in your blower door test in Merchantville, NJ helps maintain lower energy bills and fulfills local code obligations.

Preparing for a Blower Door Test in Merchantville, NJ

When preparing for blower door test in Merchantville, NJ, we first switch off the home’s heating, cooling, and exhaust 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. With all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. After the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Merchantville, NJ energy standards.
