What Is A Blower Door Test?

A blower door test evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. 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 Stone Harbor borough, NJ assists in finding and sealing air leaks early to improve home comfort, energy efficiency, and overall durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Stone Harbor borough, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the NJ climate.

What Is A Passing Blower Door Test Score?

In Stone Harbor borough, 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. Complying with this benchmark during a blower door test in Stone Harbor borough, NJ helps cut energy expenses and meet local building regulations.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Use an air barrier system such as Tyvek or Zip Sheathing and verify that each seam is properly sealed with tape.
Use properly rated insulation with the right R-value and ensure consistent coverage throughout 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.
Properly seal all connections between conditioned and unconditioned zones, including basements, crawl spaces, and attics.
Most building departments provide detailed compliance resources — view the Philadelphia checklist example here.
Our professionals at Local Energy Audits use caulk, spray foam, and thermal imaging to detect and seal leaks on-site for better efficiency./li>

Preparing for a Blower Door Test in Stone Harbor borough, NJ

As part of preparing for blower door test in Stone Harbor borough, NJ, we power down the HVAC system along with kitchen and bathroom exhaust fans. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. After sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Stone Harbor borough, NJ.
