What Is A Blower Door Test?

A blower door test is performed to identify the rate of air changes per hour, confirming your home receives a healthy exchange of fresh air. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in Gibbsboro 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?

To carry out blower door test in Gibbsboro borough, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Construction in Gibbsboro borough, NJ must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. When your blower door test in Gibbsboro borough, NJ meets this requirement, you ensure energy efficiency and maintain compliance with building codes.

Preparing for a Blower Door Test in Gibbsboro borough, NJ

To properly prepare for blower door test in Gibbsboro borough, NJ, the HVAC system and all bathroom and kitchen fans are turned off. Next, our team walks through the home to verify that every exterior door and window is sealed shut — including access points to unfinished basements, garages, or areas beyond the thermal envelope. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. After the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors on-site. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Gibbsboro borough, NJ.
