What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. 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 can also lead to drafts and discomfort caused by air leaks, along with moisture, condensation, and mold problems inside the home. A blower door test in Prospect Park, NJ helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Prospect Park, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.

What Is A Passing Blower Door Test Score?

In Prospect Park, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Meeting this requirement during your blower door test in Prospect Park, NJ helps reduce energy costs while keeping your home compliant with local building codes.

Why Do I Need A Blower Door Test?

Across NJ, the IECC (International Energy Conservation Code) is adopted by the state and local jurisdictions, requiring blower door test on residential constructions and renovations. We often collaborate with home builders, contractors, and homeowners who require blower door test in Prospect Park, NJ to meet energy efficiency standards and close permits. A duct leakage test may also be performed when ductwork or HVAC equipment extends beyond the thermal envelope. Learn more about energy code compliance.

Homeowners experience real energy benefits from blower door test in Prospect Park, NJ. The fan’s depressurization highlights air leaks, helping identify inefficiencies that can be sealed for savings. A blower door test requires minimal time but makes a long-lasting impact on home comfort and energy performance during NJ’ extreme temperatures.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Use materials like Tyvek or Zip Sheathing as your air barrier and ensure every seam is well taped for best results.
Use insulation of the correct R-value and confirm that it’s tightly installed throughout every section 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.
Ensure all penetrations between conditioned and unconditioned areas—like attics, basements, and crawl spaces—are tightly sealed.
Local building authorities commonly offer checklists to verify code compliance — review the Philadelphia example here.
Local Energy Audits provides on-site leak detection and sealing using advanced thermal imaging tools, caulk, and spray foam./li>
In most situations—over 90% of the time—we get a passing score within two hours and finalize all required paperwork.

Preparing for a Blower Door Test in Prospect Park, NJ

To prepare a home for blower door test in Prospect Park, NJ, we shut off the HVAC system and disable all exhaust fans. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other spaces outside the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and 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. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Prospect Park, NJ.
