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. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors. A blower door test in Bordentown township, NJ helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Bordentown township, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.

Preparing for a Blower Door Test in Bordentown township, NJ

Before starting blower door test in Bordentown township, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. 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 the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. After the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas 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 completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Bordentown township, NJ.
