What Is A Blower Door Test?

A blower door test is designed to measure air changes per hour inside homes, promoting a balance between airtightness and necessary ventilation. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Montville, NJ makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Montville, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the NJ climate.

What Is A Passing Blower Door Test Score?

In Montville, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. Meeting this requirement during your blower door test in Montville, NJ helps reduce energy costs while keeping your home compliant with local building codes.

Preparing for a Blower Door Test in Montville, NJ

Getting ready for blower door test in Montville, NJ involves turning off all heating, cooling, and exhaust ventilation systems. 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. Once everything is sealed, we choose a centrally located exterior door and set up the blower door frame and fan. The fan then depressurizes the home to 50 Pascals, allowing us to measure airflow and leakage precisely. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Montville, NJ energy standards.
