What Is A Blower Door Test?

A blower door test measures how many air changes per hour occur in your home, ensuring fresh air circulation and improved indoor air quality. 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. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Upperdeerfield, NJ assists in finding and sealing air leaks early to improve home comfort, energy efficiency, and overall durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Upperdeerfield, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the NJ climate.

What Is A Passing Blower Door Test Score?

Homes built in Upperdeerfield, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. Meeting this requirement during your blower door test in Upperdeerfield, NJ helps reduce energy costs while keeping your home compliant with local building codes.

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.
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.
Eliminate air leaks by sealing all openings between conditioned areas and unconditioned spaces, including basements and attics.
Building departments typically release step-by-step compliance lists — download the Philadelphia sample here as an example.

Preparing for a Blower Door Test in Upperdeerfield, NJ

Getting ready for blower door test in Upperdeerfield, NJ involves turning off all heating, cooling, and exhaust ventilation systems. We continue with a walkthrough inspection to confirm every exterior door and window is firmly closed — especially those to unconditioned spaces outside the thermal envelope. Once all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. 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. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Upperdeerfield, NJ.

Blower Door Test for Contractors in Upperdeerfield, NJ

Most professionally insulated homes undergoing blower door test in Upperdeerfield, NJ can resolve small issues on-site during the contractor’s visit. Using simple yet effective materials like chalk and spray foam, we can seal most small leaks or gaps right during testing.
