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. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. Excessive air changes often cause drafts, discomfort, and humidity-related issues such as condensation and mold growth inside the home. A blower door test in Stone Harbor, 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 perform blower door test in Stone Harbor, NJ, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Homes built in Stone Harbor, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. In most areas, an acceptable blower door test result is 3 air changes per hour or less, confirming that the home achieves optimal energy efficiency. Passing this threshold during your blower door test in Stone Harbor, NJ ensures both energy savings and full compliance with local regulations.

Preparing for a Blower Door Test in Stone Harbor, NJ

To properly prepare for blower door test in Stone Harbor, NJ, the HVAC system and all bathroom and kitchen fans are turned off. 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 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 pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. With the help of a thermal imager, we can uncover leaks and weak spots by spotting temperature differences across walls, ceilings, and surfaces near 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. Once sealing work is done, we immediately retest to verify that the desired blower door score has been achieved for compliance with local standards in Stone Harbor, NJ.
