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. Excessive air changes can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Middlesex, NJ helps uncover these issues early, enabling homeowners and builders to detect air leaks, enhance energy efficiency, and ensure a more comfortable, long-lasting home.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Middlesex, 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. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. 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?

In Middlesex, NJ, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Reaching the target during your blower door test in Middlesex, NJ guarantees lower energy consumption and full code compliance.

Ensure insulation with the specified R-value is properly installed and fitted throughout the entire building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal cracks and openings between conditioned interiors and unconditioned areas such as crawl spaces, attics, and basements.
Local authorities often publish checklists to confirm compliance — get the Philadelphia example here.
Using thermal imaging technology along with caulk and spray foam, Local Energy Audits identifies and seals leaks during the inspection./li>

Preparing for a Blower Door Test in Middlesex, NJ

To get ready for blower door test in Middlesex, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom fans. We follow with a quick walkthrough to ensure all exterior doors and windows are fully closed — including those that connect to garages, basements, or any part outside the thermal envelope. Once preparation is complete, the blower door fan and frame are installed in a centrally located exterior door. The fan then reduces pressure to 50 Pascals, allowing accurate leakage assessment. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors on-site. After all leaks are sealed, we retest immediately to confirm the desired blower door score has been met and that your home satisfies efficiency requirements in Middlesex, NJ.
