What Is A Blower Door Test?

A blower door test calculates the rate of air changes per hour in a property, verifying that proper ventilation keeps air fresh and clean. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Palmyra, NJ finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Palmyra, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. 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 drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the NJ climate.

What Is A Passing Blower Door Test Score?

Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. By meeting this standard in your blower door test in Palmyra, NJ, you can enjoy lower utility bills and peace of mind with code compliance.

Preparing for a Blower Door Test in Palmyra, NJ

Preparation for blower door test in Palmyra, NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. Next, we inspect each room to confirm all exterior doors and windows are properly closed — including any leading to garages, basements, or other spaces beyond the thermal envelope. After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed 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. 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 Palmyra, NJ.
