What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in West New York, 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?

During blower door test in West New York, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. 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 West New York, NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. Passing this requirement during a blower door test in West New York, NJ keeps your home efficient and aligned with local building code standards.

Why Do I Need A Blower Door Test?

NJ, along with many city governments, enforces the IECC, which requires blower door test for residential projects after construction or renovation. We regularly provide blower door test in West New York, NJ for home builders, contractors, and homeowners working to meet local code requirements and close permits.

Homeowners gain major advantages from blower door test in West New York, NJ. As the fan depressurizes the home, incoming air through leaks becomes easier to detect, revealing problem spots and potential energy-saving improvements. In only a few hours, a blower door test can deliver a long-lasting impact on energy efficiency, comfort, and indoor performance throughout NJ’ changing seasons.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Use high-quality air barrier materials like Tyvek or Zip Sheathing and confirm all seams are perfectly taped.
Install correctly rated insulation with the proper R-value and confirm it’s well positioned in every part of the 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 jurisdictions frequently publish compliance checklists — the Philadelphia version can be downloaded here.
With the help of thermal imaging tools, caulk, and spray foam, Local Energy Audits efficiently detects and seals leaks on-site./li>

Preparing for a Blower Door Test in West New York, NJ

To ensure accuracy during blower door test in West New York, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces outside the thermal envelope. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. 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. 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 West New York, NJ.
