What Is A Blower Door Test?

A blower door test measures the air changes per hour within a home or building. Air exchange is a normal and healthy process that allows stale indoor air to be replaced with fresh air. An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in Mount Olive, NJ assists in finding and sealing air leaks early to improve home comfort, energy efficiency, and overall durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Mount Olive, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under NJ conditions.

What Is A Passing Blower Door Test Score?

Construction in Mount Olive, NJ must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Meeting this level during your blower door test in Mount Olive, NJ supports energy efficiency and verifies that your home meets local codes.

Preparing for a Blower Door Test in Mount Olive, NJ

To properly prepare for blower door test in Mount Olive, NJ, the HVAC system and all bathroom and kitchen fans are turned off. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond the thermal envelope. With the home properly sealed, we mount the blower door frame and fan in a central exterior door, using it to depressurize to 50 Pascals for exact airflow readings. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Mount Olive, NJ.
