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. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Woodbury city, 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?

To perform blower door test in Woodbury city, NJ, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.

What Is A Passing Blower Door Test Score?

In Woodbury city, NJ, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. Reaching this target in your blower door test in Woodbury city, NJ helps maintain lower energy bills and fulfills local code obligations.

Ensure the insulation used meets the proper R-value and is well fitted throughout the structure’s building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal every transition point between conditioned and unconditioned environments, including attics, crawl spaces, and basements.

Preparing for a Blower Door Test in Woodbury city, NJ

To get ready for blower door test in Woodbury city, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom 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. With all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Woodbury city, NJ.
