What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in Palm, PA 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?

To perform blower door test in Palm, PA, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in PA climates.

What Is A Passing Blower Door Test Score?

Homes built in Palm, PA are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Meeting this level during your blower door test in Palm, PA supports energy efficiency and verifies that your home meets local codes.

Preparing for a Blower Door Test in Palm, PA

To prepare for blower door test in Palm, PA, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. 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 sealed, we choose a centrally located exterior door and set up the blower door frame and fan. The fan then depressurizes the home to 50 Pascals, allowing us to measure airflow and leakage precisely. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Palm, PA energy code requirements.
