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. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Haddonfield borough, NJ identifies air leakage issues before they become serious, ensuring efficiency, comfort, and long-term durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Haddonfield borough, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Haddonfield borough, NJ, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties.

Preparing for a Blower Door Test in Haddonfield borough, NJ

Preparation for blower door test in Haddonfield borough, NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. Next, our team walks through the home to verify that every exterior door and window is sealed shut — including access points to unfinished basements, garages, or areas beyond 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 home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. We carry chalk, spray foam, and weatherstripping materials, allowing us to work directly with homeowners or contractors to fix visible air leakage issues on-site. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Haddonfield borough, NJ building codes.
