What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Bayonne, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. 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?

In Bayonne, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. In most areas, an acceptable blower door test result is 3 air changes per hour or less, confirming that the home achieves optimal energy efficiency. By meeting this standard in your blower door test in Bayonne, NJ, you can enjoy lower utility bills and peace of mind with code compliance.

Preparing for a Blower Door Test in Bayonne, NJ

To properly prepare for blower door test in Bayonne, NJ, the HVAC system and all bathroom and kitchen fans are turned off. 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. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. 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 Bayonne, NJ.
