What Is A Blower Door Test?

A blower door test is designed to measure air changes per hour inside homes, promoting a balance between airtightness and necessary ventilation. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in Lower township, NJ detects air leaks early on, helping builders and homeowners boost efficiency and strengthen overall home comfort.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Lower township, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. 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 nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the NJ climate.

What Is A Passing Blower Door Test Score?

In Lower township, NJ, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. Complying with this benchmark during a blower door test in Lower township, NJ helps cut energy expenses and meet local building regulations.

Why Do I Need A Blower Door Test?

The State of NJ and local municipalities have implemented the IECC code, which mandates blower door test on new and remodeled residential homes. Our experts assist home builders, contractors, and homeowners needing blower door test in Lower township, NJ to ensure compliance with energy codes and complete final permits. A duct leakage test is often required whenever ducts or HVAC units are found outside the building’s thermal envelope. Learn more about energy code compliance.

Homeowners gain major advantages from blower door test in Lower township, NJ. As the fan depressurizes the home, incoming air through leaks becomes easier to detect, revealing problem spots and potential energy-saving improvements. A blower door test usually takes just a few hours but delivers a long-lasting impact on your home’s comfort, performance, and efficiency—particularly during NJ’ hot summers and cool winters.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Install an effective air barrier, for example Tyvek or Zip Sheathing, and make certain all seams are sealed with durable tape.
Ensure the insulation used meets the proper R-value and is well fitted throughout the structure’s 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 complete sealing of all openings between conditioned rooms and unconditioned areas like basements, attics, and crawl spaces.
Building departments typically release step-by-step compliance lists — download the Philadelphia sample here as an example.
Local Energy Audits identifies and repairs leaks on-site using thermal imaging tools, caulk, and high-quality spray foam./li>

Preparing for a Blower Door Test in Lower township, NJ

To ensure accuracy during blower door test in Lower township, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. Next, we conduct a quick walkthrough of the home, confirming that all exterior doors and windows are securely closed — including those to unfinished basements, garages, or any area 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 the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Lower township, NJ energy efficiency codes.

Blower Door Test for Contractors in Lower township, NJ

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