What Is A Blower Door Test?

A blower door test evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. Too frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors. A blower door test in Hackensack, NJ finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Hackensack, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. 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.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

Preparing for a Blower Door Test in Hackensack, NJ

To prepare for blower door test in Hackensack, NJ, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. 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. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. 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 Hackensack, NJ.
