What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. Too frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. Excessive air changes can also lead to drafts and discomfort caused by air leaks, along with moisture, condensation, and mold problems inside the home. A blower door test in Birdsboro, PA helps spot air leaks before they worsen, improving efficiency, comfort, and long-term structural quality.

What Our Clients Say

How Is A Blower Door Test Conducted?

To perform blower door test in Birdsboro, PA, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the PA climate.

What Is A Passing Blower Door Test Score?

Homes throughout Birdsboro, PA are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. Passing this requirement during a blower door test in Birdsboro, PA keeps your home efficient and aligned with local building code standards.

Why Do I Need A Blower Door Test?

The State of PA and its local governments follow the IECC standards, which require blower door test on newly built or remodeled residential dwellings. We work closely with home builders, contractors, and homeowners who need blower door test in Birdsboro, PA to ensure compliance and successful project completion. 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 experience real energy benefits from blower door test in Birdsboro, PA. The fan’s depressurization highlights air leaks, helping identify inefficiencies that can be sealed for savings. 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.
Apply an effective air barrier such as Tyvek or Zip Sheathing, ensuring every seam is tightly sealed with proper tape.
Use insulation featuring the proper R-value and verify complete, gap-free coverage across 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.
Seal the transitions between conditioned and unconditioned zones, particularly around basements, attics, and crawl spaces.
Many cities provide compliance checklists through their building departments — see the Philadelphia version here.
Using thermal imaging technology along with caulk and spray foam, Local Energy Audits identifies and seals leaks during the inspection./li>
Over 90% of our projects pass within two hours, with all required paperwork issued immediately to close the permit.

Preparing for a Blower Door Test in Birdsboro, PA

We start the process of blower door test in Birdsboro, PA by ensuring all heating, air conditioning, and exhaust systems are turned off. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve the thermal envelope. Once all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and 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 sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Birdsboro, PA building codes.
