What Is A Blower Door Test?

A blower door test is performed to identify the rate of air changes per hour, confirming your home receives a healthy exchange of fresh air. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home. A blower door test in Monroe township, NJ makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

To perform blower door test in Monroe township, NJ, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.

What Is A Passing Blower Door Test Score?

Construction in Monroe township, NJ must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. When your blower door test in Monroe township, NJmeets this requirement, you benefit from reduced energy bills and code compliance.

Preparing for a Blower Door Test in Monroe township, NJ

To prepare for blower door test in Monroe township, NJ, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. 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 everything is closed off, we set up the blower door fan on a centrally located exterior door and depressurize the interior to 50 Pascals to assess air leakage accurately. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. 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 sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Monroe township, NJ.
