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. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Millville city, NJ makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Millville city, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.

What Is A Passing Blower Door Test Score?

In Millville city, NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. Meeting this requirement during your blower door test in Millville city, 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.
Seal off any access points or gaps between conditioned and unconditioned spaces like attics, crawl spaces, and basements.

Preparing for a Blower Door Test in Millville city, NJ

Preparation for blower door test in Millville city, NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. We then perform a detailed walkthrough to verify that all exterior windows and doors are tightly shut, including any that lead to spaces beyond the thermal envelope. Once all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Millville city, NJ.
