What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. When there are too many air leaks, drafts and discomfort can occur, along with moisture problems such as mold and condensation. A blower door test in Bloomfield, NJ detects air leaks early on, helping builders and homeowners boost efficiency and strengthen overall home comfort.

What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Bloomfield, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. 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 the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.

What Is A Passing Blower Door Test Score?

Homes built in Bloomfield, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Passing this threshold during your blower door test in Bloomfield, NJ ensures both energy savings and full compliance with local regulations.

Preparing for a Blower Door Test in Bloomfield, NJ

For blower door test in Bloomfield, NJ, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust fans. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve the thermal envelope. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Bloomfield, NJ efficiency standards.
