What Is A Blower Door Test?

A blower door test helps determine the air changes per hour to confirm that your home has sufficient fresh air replacement. Too many air changes, however, can be detrimental because every time the air is replaced, it must be reheated or recooled, leading to higher energy use and lower efficiency. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in Marlboro, NJ detects early-stage air leaks, enabling effective energy use and a more durable, comfortable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Marlboro, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under NJ weather.

What Is A Passing Blower Door Test Score?

In Marlboro, NJ, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. 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. Achieving this goal during your blower door test in Marlboro, NJ promotes energy savings and demonstrates adherence to local building rules.

Preparing for a Blower Door Test in Marlboro, NJ

Before starting blower door test in Marlboro, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. 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. 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 pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Marlboro, NJ energy standards.
