What Is A Blower Door Test?

A blower door test helps calculate air changes per hour in your property. This natural air exchange process refreshes the indoor environment with new air. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. 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 Saddle River, NJ identifies air leakage issues before they become serious, ensuring efficiency, comfort, and long-term durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Saddle River, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under NJ conditions.

What Is A Passing Blower Door Test Score?

Homes built in Saddle River, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. Complying with this benchmark during a blower door test in Saddle River, NJ helps cut energy expenses and meet local building regulations.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Choose an appropriate air barrier, like Tyvek or Zip Sheathing, and ensure all seams are accurately and securely taped.
Use properly rated insulation with the right R-value and ensure consistent coverage throughout 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.
Seal off any access points or gaps between conditioned and unconditioned spaces like attics, crawl spaces, and basements.
Many local municipalities issue code compliance checklists — the Philadelphia example is available here.
Local Energy Audits uses thermal imaging tools, caulk, and spray foam to detect and seal leaks directly on-site./li>

Preparing for a Blower Door Test in Saddle River, NJ

To get ready for blower door test in Saddle River, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom fans. 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. With all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. 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. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Saddle River, NJ.
