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 many air changes, however, can be detrimental because every time the air is replaced, it must be reheated or recooled, leading to higher energy use and lower 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 Norwood, PA allows early detection of air leaks, helping homeowners and builders boost efficiency and maintain a comfortable, durable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Norwood, PA, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the PA climate.

What Is A Passing Blower Door Test Score?

Homes built in Norwood, PA are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. For most regions, achieving 3 air changes per hour or less on a blower door test ensures that the home is properly energy efficient. Achieving this standard in your blower door test in Norwood, PA lowers utility bills and guarantees adherence to local code requirements.

Preparing for a Blower Door Test in Norwood, PA

We start the process of blower door test in Norwood, PA by ensuring all heating, air conditioning, and exhaust systems are turned off. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining the thermal envelope. Once all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. Once pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent 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 leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Norwood, PA.
