Test your home’s air barriers and meet energy regulations through dependable blower door test in Southampton, PA. Our experts help homeowners, builders, and contractors pinpoint air leaks, improve efficiency, and comply with PA building energy standards.

What Is A Blower Door Test?

A blower door test helps calculate air changes per hour in your property. This natural air exchange process refreshes the indoor environment with new air. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Southampton, PA detects air leaks early on, helping builders and homeowners boost efficiency and strengthen overall home comfort.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Southampton, PA, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. 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 built in Southampton, PA are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Satisfying this requirement in your blower door test in Southampton, PA helps optimize energy use and ensures you meet local building standards.

Install insulation that meets the required R-value and check that it’s evenly and securely placed throughout the building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Close gaps and penetrations between conditioned zones and unconditioned sections like attics, basements, and crawl spaces.
Local building authorities commonly offer checklists to verify code compliance — review the Philadelphia example here.

Preparing for a Blower Door Test in Southampton, PA

As part of preparing for blower door test in Southampton, PA, we power down the HVAC system along with kitchen and bathroom exhaust fans. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces outside the thermal envelope. After ensuring the home is fully sealed, we mount the blower door fan and frame on a central exterior door and depressurize the interior to 50 Pascals for accurate testing. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Southampton, PA.
