What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. When there are too many air leaks, drafts and discomfort can occur, along with moisture problems such as mold and condensation. A blower door test in Spring Lake, 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?

During blower door test in Spring Lake, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. 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 extracts air, exterior air begins entering the house through any unsealed spaces or cracks. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in NJ.

What Is A Passing Blower Door Test Score?

In Spring Lake, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. 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 Spring Lake, NJ helps maintain lower energy bills and fulfills local code obligations.

Use Tyvek or Zip Sheathing as your air barrier and carefully tape all seams to prevent air leakage.
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.
Close any gaps connecting conditioned and unconditioned spaces, such as those leading to basements, attics, or crawl spaces.
Building departments in many areas share checklists for verifying compliance — download the Philadelphia version here as a sample.

Preparing for a Blower Door Test in Spring Lake, NJ

We start the process of blower door test in Spring Lake, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. Next, a brief home walkthrough ensures every exterior door and window is closed — even those opening to unconditioned areas like garages or basements outside the thermal envelope. Once all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining 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. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Spring Lake, NJ.
