What Is A Blower Door Test?

A blower door test checks the number of air changes per hour in your home, ensuring old air is replaced with new, clean air for a healthier environment. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Highland Lakes, 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. 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.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.

What Is A Passing Blower Door Test Score?

In Highland Lakes, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Passing this threshold during your blower door test in Highland Lakes, NJ ensures both energy savings and full compliance with local regulations.

Preparing for a Blower Door Test in Highland Lakes, NJ

We start the process of blower door test in Highland Lakes, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces 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. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Highland Lakes, NJ efficiency codes.
