What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in West Collingswood, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under NJ conditions.

Preparing for a Blower Door Test in West Collingswood, NJ

Preparation for blower door test in West Collingswood, NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. We follow with a quick walkthrough to ensure all exterior doors and windows are fully closed — including those that connect to garages, basements, or any part outside the thermal envelope. After sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to West Collingswood, NJ energy efficiency codes.
