What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use 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 Mount Ephraim, NJ detects early-stage air leaks, enabling effective energy use and a more durable, comfortable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Mount Ephraim, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. 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 device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under NJ weather.

What Is A Passing Blower Door Test Score?

In Mount Ephraim, NJ, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. Achieving this standard in your blower door test in Mount Ephraim, NJ lowers utility bills and guarantees adherence to local code requirements.

Why Do I Need A Blower Door Test?

Throughout NJ, the IECC (International Energy Conservation Code) is followed, making blower door test compulsory for new and renovated homes.

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.
Fit insulation with the correct R-value and make sure it’s installed without voids across the entire 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 permitting offices often offer official compliance checklists — review the Philadelphia sample here for reference.
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 Mount Ephraim, NJ

Before conducting blower door test in Mount Ephraim, NJ, we make sure all heating, cooling, and ventilation fans are switched off. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining the thermal envelope. After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. 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. Once sealing is complete, we perform an immediate retest to verify that the desired blower door score is achieved and that your home meets all energy efficiency requirements in Mount Ephraim, NJ.
