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. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. Too many air changes can result in drafts and leaks that create discomfort and lead to moisture, mold, and condensation issues. A blower door test in Rahway, NJ finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Rahway, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Construction in Rahway, NJ must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. Generally, a blower door test result of 3 air changes per hour or less is considered acceptable, ensuring proper energy performance. Reaching this target in your blower door test in Rahway, NJ helps maintain lower energy bills and fulfills local code obligations.

Why Do I Need A Blower Door Test?

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Use a trusted air barrier like Tyvek or Zip Sheathing, ensuring all joints and seams are properly taped and sealed.
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.
Ensure all penetrations between conditioned and unconditioned areas—like attics, basements, and crawl spaces—are tightly sealed.
Local code offices often issue compliance checklists — access the Philadelphia example here for reference.
With the help of thermal imaging tools, caulk, and spray foam, Local Energy Audits efficiently detects and seals leaks on-site./li>

Preparing for a Blower Door Test in Rahway, NJ

We start the process of blower door test in Rahway, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Rahway, NJ building codes.
