What Is A Blower Door Test?

A blower door test measures the air changes per hour within a home or building. Air exchange is a normal and healthy process that allows stale indoor air to be replaced with fresh air. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Haledon, 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 conduct blower door test in Haledon, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal 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?

Homes built in Haledon, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Satisfying this requirement in your blower door test in Haledon, NJ helps optimize energy use and ensures you meet local building standards.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Apply an air barrier like Tyvek or Zip Sheathing, making sure all connecting seams are properly taped and sealed.
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 off any access points or gaps between conditioned and unconditioned spaces like attics, crawl spaces, and basements.

Preparing for a Blower Door Test in Haledon, NJ

Before starting blower door test in Haledon, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining 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 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. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Haledon, NJ energy standards.

Blower Door Test for Contractors in Haledon, NJ

For contractors conducting blower door test in Haledon, NJ, well-insulated homes generally require only minimal on-site corrections during the test.
