What Is A Blower Door Test?

A blower door test determines the air changes per hour of a house or building, ensuring proper ventilation as old air cycles out and fresh air flows in. An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. Excessive air changes often cause drafts, discomfort, and humidity-related issues such as condensation and mold growth inside the home. A blower door test in Galloway township, NJ allows early detection of air leaks, helping homeowners and builders boost efficiency and maintain a comfortable, durable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Galloway township, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the NJ environment.

In Galloway township, NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally.

Preparing for a Blower Door Test in Galloway township, NJ

We start the process of blower door test in Galloway township, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. We then perform a detailed walkthrough to verify that all exterior windows and doors are tightly shut, including any that lead to spaces beyond the thermal envelope. 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. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. With the help of a thermal imager, we can uncover leaks and weak spots by spotting temperature differences across walls, ceilings, and surfaces near unconditioned spaces. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Galloway township, NJ efficiency codes.
