What Is A Blower Door Test?

A blower door test is designed to measure air changes per hour inside homes, promoting a balance between airtightness and necessary ventilation. Too frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s 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 Edgewater, NJ helps spot air leaks before they worsen, improving efficiency, comfort, and long-term structural quality.

What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Edgewater, NJ, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under NJ conditions.

What Is A Passing Blower Door Test Score?

In Edgewater, NJ, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. An acceptable blower door test result in most areas is 3 air changes per hour or less, demonstrating solid energy performance. Meeting this requirement during your blower door test in Edgewater, NJ helps reduce energy costs while keeping your home compliant with local building codes.

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Eliminate air leaks by sealing all openings between conditioned areas and unconditioned spaces, including basements and attics.

Preparing for a Blower Door Test in Edgewater, NJ

When preparing for blower door test in Edgewater, NJ, we first switch off the home’s heating, cooling, and exhaust systems. 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. With the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. After sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Edgewater, NJ.
