What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. Excessive air changes can also lead to drafts and discomfort caused by air leaks, along with moisture, condensation, and mold problems inside the home. A blower door test in Morristown, NJ helps homeowners and builders find and fix leaks promptly, boosting energy efficiency and indoor comfort for years to come.

What Our Clients Say

How Is A Blower Door Test Conducted?

When performing blower door test in Morristown, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.

What Is A Passing Blower Door Test Score?

Construction in Morristown, NJ must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. When your blower door test in Morristown, NJmeets this requirement, you benefit from reduced energy bills and code compliance.

Homeowners who choose blower door test in Morristown, NJ can easily locate leaks. As the fan depressurizes the home, airflow through gaps becomes apparent, exposing areas needing improvement. Completing a blower door test takes just a few hours, yet its long-lasting impact enhances comfort and performance in every NJseason.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Choose an appropriate air barrier, like Tyvek or Zip Sheathing, and ensure all seams are accurately and securely taped.
Use insulation of the correct R-value and confirm that it’s tightly installed throughout every section 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.
Ensure complete sealing of all openings between conditioned rooms and unconditioned areas like basements, attics, and crawl spaces.
Local code offices often issue compliance checklists — access the Philadelphia example here for reference.
With the help of thermal imaging tools, caulk, and spray foam, Local Energy Audits efficiently detects and seals leaks on-site./li>

Preparing for a Blower Door Test in Morristown, NJ

Before conducting blower door test in Morristown, NJ, we make sure all heating, cooling, and ventilation fans are switched off. 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. After sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Morristown, NJ.
