What Is A Blower Door Test?

A blower door test evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. Too many air changes, however, can be detrimental because every time the air is replaced, it must be reheated or recooled, leading to higher energy use and lower efficiency. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Roselle, NJ helps discover hidden leaks early so homeowners can save energy, enhance comfort, and improve home resilience.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Roselle, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the NJ environment.

What Is A Passing Blower Door Test Score?

In Roselle, NJ, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Complying with this benchmark during a blower door test in Roselle, NJ helps cut energy expenses and meet local building regulations.

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 gaps and openings separating conditioned spaces from unconditioned areas, including crawl spaces, basements, and attics.
Local authorities often publish checklists to confirm compliance — get the Philadelphia example here.
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 Roselle, NJ

To get ready for blower door test in Roselle, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom fans. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within the thermal envelope. With the home properly sealed, we mount the blower door frame and fan in a central exterior door, using it to depressurize to 50 Pascals for exact airflow readings. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. 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. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Roselle, NJ building codes.
