What Is A Blower Door Test?

A blower door test helps determine the air changes per hour to confirm that your home has sufficient fresh air replacement. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Maplewood, NJ makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Maplewood, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. 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?

Residential buildings in Maplewood, NJ must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Complying with this benchmark during a blower door test in Maplewood, NJ helps cut energy expenses and meet local building regulations.

Through blower door test in Maplewood, NJ, homeowners can easily find leaks. When the fan reduces internal pressure, air movement through problem areas becomes noticeable, offering chances to save energy. Although it’s a short process, a blower door test produces a long-lasting impact by improving comfort and lowering energy costs throughout NJ’ climate extremes.

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.
Install insulation that meets the required R-value and check that it’s evenly and securely placed 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.
Local authorities often publish checklists to confirm compliance — get the Philadelphia example here.

Preparing for a Blower Door Test in Maplewood, NJ

We start the process of blower door test in Maplewood, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. 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. Once all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. 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 arrive with chalk, spray foam, and weatherstripping materials, ready to work with homeowners or contractors to fix visible air leakage problems right away. 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 Maplewood, NJ.
