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. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Morristown, NJ finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

To conduct blower door test in Morristown, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. 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.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. 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?

Homes built in Morristown, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. Passing this threshold during your blower door test in Morristown, NJ ensures both energy savings and full compliance with local regulations.

Why Do I Need A Blower Door Test?

Both NJ and local jurisdictions adopt the IECC energy code, making blower door test mandatory for new and renovated residential structures. We often collaborate with home builders, contractors, and homeowners who require blower door test in Morristown, NJ to meet energy efficiency standards and close permits. A duct leakage test might be necessary if your home’s HVAC units or ducts are located outside its thermal envelope. Learn more about energy code compliance.

Homeowners see real value in blower door test in Morristown, NJ. As the fan draws air out, leaks become clear, making it easy to target repairs and improve efficiency. Although it’s a short process, a blower door test produces a long-lasting impact by improving comfort and lowering energy costs throughout NJ’ climate extremes.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Apply an effective air barrier such as Tyvek or Zip Sheathing, ensuring every seam is tightly sealed with proper tape.
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 joints and gaps that connect conditioned and unconditioned areas such as basements, attics, and crawl spaces.
Building departments typically release step-by-step compliance lists — download the Philadelphia sample here as an example.
Local Energy Audits is equipped with thermal imaging tools, caulk, and spray foam to find and seal air leaks immediately on-site./li>

Preparing for a Blower Door Test in Morristown, NJ

Preparation for blower door test in Morristown, NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve the thermal envelope. Once everything is closed off, we set up the blower door fan on a centrally located exterior door and depressurize the interior to 50 Pascals to assess air leakage accurately. Once pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and 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. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Morristown, NJ.
