What Is A Blower Door Test?

A blower door test helps calculate air changes per hour in your property. This natural air exchange process refreshes the indoor environment with new air. Too many air changes, however, can be detrimental because every time the air is replaced, it must be reheated or recooled, leading to higher energy use and lower efficiency. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors. A blower door test in Voorhees township, NJ helps homeowners and builders find and fix leaks promptly, boosting energy efficiency and indoor comfort for years to come.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Voorhees township, NJ, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.

What Is A Passing Blower Door Test Score?

In Voorhees township, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. Meeting this level during your blower door test in Voorhees township, NJ supports energy efficiency and verifies that your home meets local codes.

Preparing for a Blower Door Test in Voorhees township, NJ

Before conducting blower door test in Voorhees township, NJ, we make sure all heating, cooling, and ventilation fans are switched off. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond the thermal envelope. Once all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Voorhees township, NJ energy efficiency codes.
