Blower Door Test in Laurel Springs, NJ

Ensure your property meets energy codes and maintains efficiency through expert blower door test in Laurel Springs, NJ. Our certified team partners with homeowners, builders, and contractors to uncover air leaks, enhance comfort, and ensure NJ energy code adherence.

What Is A Blower Door Test?

A blower door test helps calculate air changes per hour in your property. This natural air exchange process refreshes the indoor environment with new air. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Laurel Springs, NJ helps spot air leaks before they worsen, improving efficiency, comfort, and long-term structural quality.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Laurel Springs, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. 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 Laurel Springs, NJ, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. Achieving this goal during your blower door test in Laurel Springs, NJ promotes energy savings and demonstrates adherence to local building rules.

Why Do I Need A Blower Door Test?

NJ and local city codes follow the IECC (International Energy Conservation Code), which mandates blower door tests on residential buildings after construction or renovation.

There are many benefits of blower door test in Laurel Springs, NJ for homeowners. When the fan lowers indoor pressure, leaks become visible, allowing for easy identification of inefficiencies and energy-saving opportunities. A blower door test requires minimal time but makes a long-lasting impact on home comfort and energy performance during NJ’ extreme temperatures.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Choose an appropriate air barrier, like Tyvek or Zip Sheathing, and ensure all seams are accurately and securely taped.
Apply insulation of the correct R-value and make sure it fits snugly in all areas 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.
Ensure complete sealing of all openings between conditioned rooms and unconditioned areas like basements, attics, and crawl spaces.
Local jurisdictions frequently publish compliance checklists — the Philadelphia version can be downloaded here.
Local Energy Audits brings thermal cameras, caulk, and spray foam to locate and seal leaks while performing on-site testing./li>
In over 90% of tests, we obtain a passing score within two hours and issue all paperwork required for permit closure.

Preparing for a Blower Door Test in Laurel Springs, NJ

To get ready for blower door test in Laurel Springs, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom 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. 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. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. 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. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Laurel Springs, NJ.
