What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. When there are too many air leaks, drafts and discomfort can occur, along with moisture problems such as mold and condensation. A blower door test in Wenonah, NJ finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Wenonah, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal 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 Wenonah, NJ, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Meeting this requirement during your blower door test in Wenonah, NJ helps reduce energy costs while keeping your home compliant with local building codes.

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 often work with home builders, contractors, and homeowners requiring blower door test in Wenonah, NJ to meet local energy codes and obtain permit approval.

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 all openings between conditioned and unconditioned areas, including basements, attics, and crawl spaces.

Preparing for a Blower Door Test in Wenonah, NJ

To prepare for blower door test in Wenonah, NJ, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen 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 everything is sealed, we choose a centrally located exterior door and set up the blower door frame and fan. The fan then depressurizes the home to 50 Pascals, allowing us to measure airflow and leakage precisely. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. We’re equipped with chalk, spray foam, and weatherstripping materials, so we can partner with homeowners or contractors to repair visible air leakage problems right on-site. Once sealing work is done, we immediately retest to verify that the desired blower door score has been achieved for compliance with local standards in Wenonah, NJ.
