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. Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. When there are too many air leaks, drafts and discomfort can occur, along with moisture problems such as mold and condensation. A blower door test in Brooksi, DE helps uncover these issues early, enabling homeowners and builders to detect air leaks, enhance energy efficiency, and ensure a more comfortable, long-lasting home.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Brooksi, DE, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in DE conditions.

What Is A Passing Blower Door Test Score?

In Brooksi, DE, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. Satisfying this requirement in your blower door test in Brooksi, DE helps optimize energy use and ensures you meet local building standards.

Why Do I Need A Blower Door Test?

The State of DE, together with many cities and counties, enforces the IECC (International Energy Conservation Code), which calls for blower door test on new or renovated residential properties. We often work with home builders, contractors, and homeowners requiring blower door test in Brooksi, DE to meet local energy codes and obtain permit approval. A duct leakage test requirement applies if ducts or HVAC units are positioned outside the structure’s thermal envelope. Learn more about energy code compliance.

Homeowners gain major advantages from blower door test in Brooksi, DE. As the fan depressurizes the home, incoming air through leaks becomes easier to detect, revealing problem spots and potential energy-saving improvements. A blower door test may take just a few hours, yet its long-lasting impact can greatly improve your home’s comfort and energy use across DE’ hot summers and cool winters.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Choose an appropriate air barrier, like Tyvek or Zip Sheathing, and ensure all seams are accurately and securely taped.
Use insulation with the right R-value and confirm it is properly installed 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.
Seal all joints and gaps that connect conditioned and unconditioned areas such as basements, attics, and crawl spaces.
Local permitting offices often offer official compliance checklists — review the Philadelphia sample here for reference.
Our professionals at Local Energy Audits use caulk, spray foam, and thermal imaging to detect and seal leaks on-site for better efficiency./li>

Preparing for a Blower Door Test in Brooksi, DE

To get ready for blower door test in Brooksi, DE, our team turns off the HVAC system and shuts down kitchen and bathroom fans. 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 everything is closed off, we set up the blower door fan on a centrally located exterior door and depressurize the interior to 50 Pascals to assess air leakage accurately. After the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. Our technicians arrive with chalk, spray foam, and weatherstripping materials, ready to work with homeowners or contractors to fix visible air leakage problems right away. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Brooksi, DE efficiency codes.
