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. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors. A blower door test in Berlin township, NJ enables early identification of air leaks, helping improve comfort, durability, and energy savings.

What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Berlin township, NJ, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the NJ climate.

What Is A Passing Blower Door Test Score?

In Berlin township, NJ, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Complying with this benchmark during a blower door test in Berlin township, NJ helps cut energy expenses and meet local building regulations.

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal off any access points or gaps between conditioned and unconditioned spaces like attics, crawl spaces, and basements.

Preparing for a Blower Door Test in Berlin township, NJ

When preparing for blower door test in Berlin township, NJ, we first switch off the home’s heating, cooling, and exhaust systems. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside the thermal envelope. After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. We carry chalk, spray foam, and weatherstripping materials, allowing us to work directly with homeowners or contractors to fix visible air leakage issues on-site. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Berlin township, NJ.
