What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. Too frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. When there are too many air leaks, drafts and discomfort can occur, along with moisture problems such as mold and condensation. A blower door test in Hi-Nella, NJ identifies air leakage issues before they become serious, ensuring efficiency, comfort, and long-term durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Hi-Nella, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Hi-Nella, NJ, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. For most regions, achieving 3 air changes per hour or less on a blower door test ensures that the home is properly energy efficient. Achieving this goal during your blower door test in Hi-Nella, NJ promotes energy savings and demonstrates adherence to local building rules.

Preparing for a Blower Door Test in Hi-Nella, NJ

When preparing for blower door test in Hi-Nella, NJ, we first switch off the home’s heating, cooling, and exhaust systems. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond 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. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Hi-Nella, NJ.
