What Is A Blower Door Test?

A blower door test measures how many air changes per hour occur in your home, ensuring fresh air circulation and improved indoor air quality. Too frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Closter, NJ identifies air leakage issues before they become serious, ensuring efficiency, comfort, and long-term durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

To perform blower door test in Closter, NJ, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Closter, NJ, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Satisfying this requirement in your blower door test in Closter, NJ helps optimize energy use and ensures you meet local building standards.

Preparing for a Blower Door Test in Closter, NJ

To prepare for blower door test in Closter, NJ, we start by turning off the heating and cooling system, along with all bathroom fans 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. 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 visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Closter, NJ.

Blower Door Test for Contractors in Closter, NJ

For contractors conducting blower door test in Closter, NJ, well-insulated homes generally require only minimal on-site corrections during the test.
