What Is A Blower Door Test?

A blower door test measures how many air changes per hour occur in your home, ensuring fresh air circulation and improved indoor air quality. Too many air changes, however, can be detrimental because every time the air is replaced, it must be reheated or recooled, leading to higher energy use and lower efficiency. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in Woodlyn, PA makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Woodlyn, PA, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. 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 sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in PA conditions.

What Is A Passing Blower Door Test Score?

Homes in Woodlyn, PA are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Achieving this standard in your blower door test in Woodlyn, PA lowers utility bills and guarantees adherence to local code requirements.

Install insulation of the appropriate R-value and inspect to confirm it’s correctly fitted in all envelope areas.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal all openings between conditioned and unconditioned areas, including basements, attics, and crawl spaces.

Preparing for a Blower Door Test in Woodlyn, PA

When preparing for blower door test in Woodlyn, PA, we first switch off the home’s heating, cooling, and exhaust systems. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. Once pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Woodlyn, PA efficiency codes.
