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. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Westwood, NJ locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

To perform blower door test in Westwood, NJ, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Houses in Westwood, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. Satisfying this requirement in your blower door test in Westwood, NJ helps optimize energy use and ensures you meet local building standards.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Apply an air barrier like Tyvek or Zip Sheathing, making sure all connecting seams are properly taped and sealed.
Ensure insulation with the specified R-value is properly installed and fitted throughout the entire 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 all openings between conditioned and unconditioned areas, including basements, attics, and crawl spaces.
Many local municipalities issue code compliance checklists — the Philadelphia example is available here.
Local Energy Audits uses thermal imaging tools, caulk, and spray foam to detect and seal leaks directly on-site./li>

Preparing for a Blower Door Test in Westwood, NJ

Before starting blower door test in Westwood, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or 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 home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Westwood, NJ efficiency standards.
