What Is A Blower Door Test?

A blower door test checks the number of air changes per hour in your home, ensuring old air is replaced with new, clean air for a healthier environment. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. Excessive air changes often cause drafts, discomfort, and humidity-related issues such as condensation and mold growth inside the home. A blower door test in Camden, DE detects early-stage air leaks, enabling effective energy use and a more durable, comfortable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Camden, DE, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. 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.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under DE weather.

What Is A Passing Blower Door Test Score?

In Camden, DE, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. Meeting this requirement during your blower door test in Camden, DE helps reduce energy costs while keeping your home compliant with local building codes.

Why Do I Need A Blower Door Test?

Following the IECC guidelines, DE and many local jurisdictions require blower door test on newly built or renovated residential dwellings. Our experts assist home builders, contractors, and homeowners needing blower door test in Camden, DE to ensure compliance with energy codes and complete final permits.

There are many benefits of blower door test in Camden, DE for homeowners. When the fan lowers indoor pressure, leaks become visible, allowing for easy identification of inefficiencies and energy-saving opportunities. Typically completed within a few hours, a blower door test provides a long-lasting impact on comfort, energy efficiency, and overall home performance in DE’ varied climate.

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Ensure complete sealing of all openings between conditioned rooms and unconditioned areas like basements, attics, and crawl spaces.

Preparing for a Blower Door Test in Camden, DE

We start the process of blower door test in Camden, DE by ensuring all heating, air conditioning, and exhaust systems are turned off. 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. Once preparation is complete, the blower door fan and frame are installed in a centrally located exterior door. The fan then reduces pressure to 50 Pascals, allowing accurate leakage assessment. 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. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. After sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Camden, DE.
