What Is A Blower Door Test?

A blower door test determines the air changes per hour of a house or building, ensuring proper ventilation as old air cycles out and fresh air flows in. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. 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 Lacey, NJ detects air leaks early on, helping builders and homeowners boost efficiency and strengthen overall home comfort.

What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Lacey, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the NJ climate.

What Is A Passing Blower Door Test Score?

Homes in Lacey, NJ are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. By meeting this standard in your blower door test in Lacey, NJ, you can enjoy lower utility bills and peace of mind with code compliance.

Preparing for a Blower Door Test in Lacey, NJ

As part of preparing for blower door test in Lacey, NJ, we power down the HVAC system along with kitchen and bathroom exhaust fans. 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 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 the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Lacey, NJ energy code requirements.
