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 air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in Washington township (Burlington), NJ locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Washington township (Burlington), NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in NJ.

Preparing for a Blower Door Test in Washington township (Burlington), NJ

When preparing for blower door test in Washington township (Burlington), NJ, we first switch off the home’s heating, cooling, and exhaust systems. Next, we conduct a quick walkthrough of the home, confirming that all exterior doors and windows are securely closed — including those to unfinished basements, garages, or any area outside 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. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. 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 Washington township (Burlington), NJ.
