What Is A Blower Door Test?

A blower door test is conducted to assess air changes per hour inside a home or structure, ensuring the right balance between air leakage and fresh airflow. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. 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 Little Egg Harbor, 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?

In preparation for blower door test in Little Egg Harbor, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. 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.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.

What Is A Passing Blower Door Test Score?

Houses in Little Egg Harbor, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version.

Passing this threshold during your blower door test in Little Egg Harbor, NJ ensures both energy savings and full compliance with local regulations.

Preparing for a Blower Door Test in Little Egg Harbor, NJ

As part of preparing for blower door test in Little Egg Harbor, NJ, we power down the HVAC system along with kitchen and bathroom exhaust fans. We continue with a walkthrough inspection to confirm every exterior door and window is firmly closed — especially those to unconditioned spaces outside the thermal envelope. Once all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to 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. 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 Little Egg Harbor, NJ.
