What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Fair Lawn, 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?

To carry out blower door test in Fair Lawn, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.

What Is A Passing Blower Door Test Score?

In Fair Lawn, NJ, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. In most jurisdictions, 3 air changes per hour or less is the benchmark for acceptable blower door test results and energy efficiency. Achieving this standard in your blower door test in Fair Lawn, NJ lowers utility bills and guarantees adherence to local code requirements.

Preparing for a Blower Door Test in Fair Lawn, NJ

We begin blower door test in Fair Lawn, NJ by switching off the HVAC system and shutting down all exhaust fans throughout the home. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. 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. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Fair Lawn, NJ.
