What Is A Blower Door Test?

A blower door test checks the number of air changes per hour in your home, ensuring old air is replaced with new, clean air for a healthier environment. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. Excessive air changes often cause drafts, discomfort, and humidity-related issues such as condensation and mold growth inside the home. A blower door test in North Hanover township, NJ enables early identification of air leaks, helping improve comfort, durability, and energy savings.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in North Hanover township, 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. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.

What Is A Passing Blower Door Test Score?

Houses in North Hanover township, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. Achieving this standard in your blower door test in North Hanover township, NJ lowers utility bills and guarantees adherence to local code requirements.

Preparing for a Blower Door Test in North Hanover township, NJ

When preparing for blower door test in North Hanover township, NJ, we first switch off the home’s heating, cooling, and exhaust systems. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining 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 the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. Our team brings chalk, spray foam, and weatherstripping supplies to every job, enabling us to collaborate with homeowners or contractors to seal visible air leakage areas immediately. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with North Hanover township, NJ efficiency standards.
