What Is A Blower Door Test?

A blower door test helps determine the air changes per hour to confirm that your home has sufficient fresh air replacement. Too frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Alburtis, PA helps uncover these issues early, enabling homeowners and builders to detect air leaks, enhance energy efficiency, and ensure a more comfortable, long-lasting home.

What Our Clients Say

How Is A Blower Door Test Conducted?

When performing blower door test in Alburtis, PA, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. 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 creates negative pressure, outside air infiltrates the home through gaps and small openings. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in PA conditions.

What Is A Passing Blower Door Test Score?

Homes throughout Alburtis, PA are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Reaching the target during your blower door test in Alburtis, PA guarantees lower energy consumption and full code compliance.

Why Do I Need A Blower Door Test?

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Use a trusted air barrier like Tyvek or Zip Sheathing, ensuring all joints and seams are properly taped and sealed.
Ensure the insulation used meets the proper R-value and is well fitted throughout the structure’s building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Ensure complete sealing of all openings between conditioned rooms and unconditioned areas like basements, attics, and crawl spaces.
Local code offices often issue compliance checklists — access the Philadelphia example here for reference.
At Local Energy Audits, we utilize thermal imaging equipment, caulk, and spray foam to identify and fix air leaks during testing./li>

Preparing for a Blower Door Test in Alburtis, PA

We start the process of blower door test in Alburtis, PA by ensuring all heating, air conditioning, and exhaust systems are turned off. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond 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 depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. With the help of a thermal imager, we can uncover leaks and weak spots by spotting temperature differences across walls, ceilings, and surfaces near unconditioned spaces. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. 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 Alburtis, PA.
