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. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in Manalapan, NJ identifies potential air leakage problems early so homeowners and builders can improve comfort, energy performance, and home durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Manalapan, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. 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?

Homes throughout Manalapan, NJ are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. Meeting this benchmark in your blower door test in Manalapan, NJ reduces ongoing energy costs while ensuring local regulatory compliance.

Why Do I Need A Blower Door Test?

Preparing for a Blower Door Test in Manalapan, NJ

For blower door test in Manalapan, NJ, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust fans. Next, we inspect each room to confirm all exterior doors and windows are properly closed — including any leading to garages, basements, or other spaces beyond the thermal envelope. After sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. Once pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Manalapan, NJ energy efficiency codes.
