What Is A Blower Door Test?

A blower door test is designed to measure air changes per hour inside homes, promoting a balance between airtightness and necessary ventilation. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Bellmawr borough, NJ detects air leaks early on, helping builders and homeowners boost efficiency and strengthen overall home comfort.

What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Bellmawr borough, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in NJ.

What Is A Passing Blower Door Test Score?

Construction in Bellmawr borough, NJ must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. In most jurisdictions, 3 air changes per hour or less is the benchmark for acceptable blower door test results and energy efficiency. When your blower door test in Bellmawr borough, NJmeets this requirement, you benefit from reduced energy bills and code compliance.

Anticipate potential air leaks before testing begins.
Use a reliable air barrier like Tyvek or Zip Sheathing and make sure all seams are securely taped.
Ensure the insulation used meets the proper R-value and is well fitted throughout the structure’s building envelope.
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.
Many cities provide compliance checklists through their building departments — see the Philadelphia version here.
Local Energy Audits identifies and repairs leaks on-site using thermal imaging tools, caulk, and high-quality spray foam./li>

Preparing for a Blower Door Test in Bellmawr borough, NJ

Preparation for blower door test in Bellmawr borough, NJ begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. We then perform a detailed walkthrough to verify that all exterior windows and doors are tightly shut, including any that lead to spaces beyond the thermal envelope. With the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. We carry chalk, spray foam, and weatherstripping materials, allowing us to work directly with homeowners or contractors to fix visible air leakage issues 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 Bellmawr borough, NJ.
