What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced 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 Mount Holly township, NJ helps discover hidden leaks early so homeowners can save energy, enhance comfort, and improve home resilience.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Mount Holly township, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in NJ.

Preparing for a Blower Door Test in Mount Holly township, NJ

As part of preparing for blower door test in Mount Holly township, NJ, we power down the HVAC system along with kitchen and bathroom exhaust fans. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve the thermal envelope. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Mount Holly township, NJ.
