Blower Door Test in Glassboro, NJ

Ensure your home is sealed properly and energy-efficient with quality blower door test in Glassboro, NJ. Our certified technicians assist homeowners, builders, and contractors in detecting hidden air leaks, boosting comfort, and ensuring full compliance with NJ energy codes.

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. An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Glassboro, NJ helps spot air leaks before they worsen, improving efficiency, comfort, and long-term structural quality.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Glassboro, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. 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 air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.

What Is A Passing Blower Door Test Score?

In Glassboro, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. Achieving this standard in your blower door test in Glassboro, NJ lowers utility bills and guarantees adherence to local code requirements.

Why Do I Need A Blower Door Test?

Both NJ and local jurisdictions adopt the IECC energy code, making blower door test mandatory for new and renovated residential structures.

  • Install insulation of the appropriate R-value and inspect to confirm it’s correctly fitted in all envelope areas.
  • Seal all penetrations in exterior walls using caulk or spray foam.
  • Ensure doors and windows are properly installed, caulked, and weather-sealed.
  • Close any gaps connecting conditioned and unconditioned spaces, such as those leading to basements, attics, or crawl spaces.

Preparing for a Blower Door Test in Glassboro, NJ

We begin blower door test in Glassboro, NJ by switching off the HVAC system and shutting down all exhaust fans throughout 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. 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. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. After all leaks are sealed, we retest immediately to confirm the desired blower door score has been met and that your home satisfies efficiency requirements in Glassboro, NJ.
