Blower Door Test in Rocky Hill, NJ

Improve insulation performance and meet energy code requirements through thorough blower door test in Rocky Hill, NJ. Our qualified specialists help homeowners, builders, and contractors locate hidden leaks, improve comfort, and fulfill NJ energy code standards.

What Is A Blower Door Test?

A blower door test is conducted to assess air changes per hour inside a home or structure, ensuring the right balance between air leakage and fresh airflow. Too frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. Excessive air changes can also lead to drafts and discomfort caused by air leaks, along with moisture, condensation, and mold problems inside the home. A blower door test in Rocky Hill, NJ assists in finding and sealing air leaks early to improve home comfort, energy efficiency, and overall durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in Rocky Hill, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under NJ weather.

What Is A Passing Blower Door Test Score?

In Rocky Hill, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. By meeting this standard in your blower door test in Rocky Hill, NJ, you can enjoy lower utility bills and peace of mind with code compliance.

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.

  • Employ an appropriate air barrier system such as Tyvek or Zip Sheathing and verify that each seam has been correctly taped.
  • Place insulation with the accurate R-value and check for proper installation and full coverage in 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 all openings between conditioned and unconditioned areas, including basements, attics, and crawl spaces.
  • Local building departments often supply a detailed checklist to ensure compliance — you can download the Philadelphia example here for guidance.
  • Local Energy Audits provides on-site leak detection and sealing using advanced thermal imaging tools, caulk, and spray foam./li>

Preparing for a Blower Door Test in Rocky Hill, NJ

We begin blower door test in Rocky Hill, NJ by switching off the HVAC system and shutting down all exhaust fans throughout the home. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other spaces outside the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Rocky Hill, NJ efficiency codes.
