Test your home’s air barriers and meet energy regulations through dependable blower door test in Crum Lynne, PA. Our trained team assists homeowners, builders, and contractors by detecting hidden air leaks, boosting comfort, and meeting PA energy regulations.

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. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. 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 Crum Lynne, PA helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

To perform blower door test in Crum Lynne, PA, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in PA conditions.

What Is A Passing Blower Door Test Score?

Homes throughout Crum Lynne, PA are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Reaching the target during your blower door test in Crum Lynne, PA guarantees lower energy consumption and full code compliance.

Why Do I Need A Blower Door Test?

If any part of the HVAC system or ductwork sits beyond the building’s thermal envelope, a duct leakage test may be required. Learn more about energy code compliance.

Homeowners gain major advantages from blower door test in Crum Lynne, PA. As the fan depressurizes the home, incoming air through leaks becomes easier to detect, revealing problem spots and potential energy-saving improvements. Typically completed within a few hours, a blower door test provides a long-lasting impact on comfort, energy efficiency, and overall home performance in PA’ varied climate.

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.
Apply the correct R-value insulation and verify that it’s properly fitted to seal the whole building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal the transitions between conditioned and unconditioned zones, particularly around basements, attics, and crawl spaces.
Local authorities often publish checklists to confirm compliance — get the Philadelphia example here.
With the help of thermal imaging tools, caulk, and spray foam, Local Energy Audits efficiently detects and seals leaks on-site./li>

Preparing for a Blower Door Test in Crum Lynne, PA

Preparation for blower door test in Crum Lynne, PA begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. Next, our team walks through the home to verify that every exterior door and window is sealed shut — including access points to unfinished basements, garages, or areas beyond 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. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Crum Lynne, PA.
