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. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Middle township, NJ helps discover hidden leaks early so homeowners can save energy, enhance comfort, and improve home resilience.

What Our Clients Say

How Is A Blower Door Test Conducted?

To perform blower door test in Middle township, NJ, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Homes built in Middle township, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. Achieving this goal during your blower door test in Middle township, NJ promotes energy savings and demonstrates adherence to local building rules.

Why Do I Need A Blower Door Test?

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.

Preparing for a Blower Door Test in Middle township, NJ

To ensure accuracy during blower door test in Middle township, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within 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. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to 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. After all leaks are sealed, we retest immediately to confirm the desired blower door score has been met and that your home satisfies efficiency requirements in Middle township, NJ.
