What Is A Blower Door Test?

A blower door test measures the air changes per hour within a home or building. Air exchange is a normal and healthy process that allows stale indoor air to be replaced with fresh air. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home. A blower door test in Pitman, NJ helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Pitman, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. 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?

Homes built in Pitman, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. Passing this requirement during a blower door test in Pitman, NJ keeps your home efficient and aligned with local building code standards.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Select a proper air barrier such as Tyvek or Zip Sheathing and ensure every seam is thoroughly taped for airtight sealing.
Apply insulation of the correct R-value and make sure it fits snugly in all areas of the building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Make sure to seal all separations between conditioned and unconditioned areas, including crawl spaces, basements, and attics.
Many cities provide compliance checklists through their building departments — see the Philadelphia version here.
Using thermal imaging technology along with caulk and spray foam, Local Energy Audits identifies and seals leaks during the inspection./li>
In more than 90% of cases, we secure a passing score within two hours and deliver the paperwork needed to close the permit.

Preparing for a Blower Door Test in Pitman, NJ

Preparation for blower door test in Pitman, NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. 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 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 structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. Once sealing is complete, we perform an immediate retest to verify that the desired blower door score is achieved and that your home meets all energy efficiency requirements in Pitman, NJ.

Blower Door Test for Contractors in Pitman, NJ

For contractors booking blower door test in Pitman, NJ, homes with quality insulation usually require only quick, on-site fixes during testing.
