What Is A Blower Door Test?

A blower door test calculates the rate of air changes per hour in a property, verifying that proper ventilation keeps air fresh and clean. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. When there are too many air leaks, drafts and discomfort can occur, along with moisture problems such as mold and condensation. A blower door test in Clifton, 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?

While performing blower door test in Clifton, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Homes throughout Clifton, NJ are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Meeting this level during your blower door test in Clifton, NJ supports energy efficiency and verifies that your home meets local codes.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Select a proper air barrier such as Tyvek or Zip Sheathing and ensure every seam is thoroughly taped for airtight sealing.
Use insulation with the right R-value and confirm it is properly installed throughout 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.
Ensure all penetrations between conditioned and unconditioned areas—like attics, basements, and crawl spaces—are tightly sealed.
Many local municipalities issue code compliance checklists — the Philadelphia example is available here.
Local Energy Audits technicians carry thermal imaging devices, caulk, and spray foam to pinpoint and seal air leaks immediately./li>

Preparing for a Blower Door Test in Clifton, NJ

Preparation for blower door test in Clifton, NJ begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. 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 the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed 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. After sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Clifton, NJ.
