What Is A Blower Door Test?

A blower door test is designed to measure air changes per hour inside homes, promoting a balance between airtightness and necessary ventilation. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Hamilton township (Mercer), NJ detects early-stage air leaks, enabling effective energy use and a more durable, comfortable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

For blower door test in Hamilton township (Mercer), NJ, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. 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.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in NJ.

What Is A Passing Blower Door Test Score?

In Hamilton township (Mercer), NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. Passing this threshold during your blower door test in Hamilton township (Mercer), NJ ensures both energy savings and full compliance with local regulations.

Through blower door test in Hamilton township (Mercer), NJ, homeowners can easily find leaks. When the fan reduces internal pressure, air movement through problem areas becomes noticeable, offering chances to save energy. A blower door test usually takes just a few hours but delivers a long-lasting impact on your home’s comfort, performance, and efficiency—particularly during NJ’ hot summers and cool winters.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Employ an appropriate air barrier system such as Tyvek or Zip Sheathing and verify that each seam has been correctly taped.
Install insulation of the appropriate R-value and inspect to confirm it’s correctly fitted in all envelope areas.
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.
Many local building offices offer a step-by-step checklist to confirm compliance — view the Philadelphia sample here.

Preparing for a Blower Door Test in Hamilton township (Mercer), NJ

To get ready for blower door test in Hamilton township (Mercer), NJ, our team turns off the HVAC system and shuts down kitchen and bathroom 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 all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to 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 sealing work is done, we immediately retest to verify that the desired blower door score has been achieved for compliance with local standards in Hamilton township (Mercer), NJ.
