What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors. A blower door test in Hillsborough township, NJ enables early identification of air leaks, helping improve comfort, durability, and energy savings.

What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Hillsborough township, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Houses in Hillsborough township, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. Complying with this benchmark during a blower door test in Hillsborough township, NJ helps cut energy expenses and meet local building regulations.

Install correctly rated insulation with the proper R-value and confirm it’s well positioned in every part of 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.
Eliminate air leaks by sealing all openings between conditioned areas and unconditioned spaces, including basements and attics.
Local authorities often publish checklists to confirm compliance — get the Philadelphia example here.
At Local Energy Audits, we utilize thermal imaging equipment, caulk, and spray foam to identify and fix air leaks during testing./li>

Preparing for a Blower Door Test in Hillsborough township, NJ

To prepare for blower door test in Hillsborough township, NJ, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve the thermal envelope. Once everything is sealed, we choose a centrally located exterior door and set up the blower door frame and fan. The fan then depressurizes the home to 50 Pascals, allowing us to measure airflow and leakage precisely. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems 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 Hillsborough township, NJ.
