Maintain compliance with energy codes and reduce energy loss using expert blower door test in Mountain Lakes, NJ. Our trained team assists homeowners, builders, and contractors by detecting hidden air leaks, boosting comfort, and meeting NJ energy regulations.

What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Mountain Lakes, NJ finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

To conduct blower door test in Mountain Lakes, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.

What Is A Passing Blower Door Test Score?

Houses in Mountain Lakes, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Achieving compliance in your blower door test in Mountain Lakes, NJ helps improve energy efficiency and meet all local code mandates.

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Close and seal every opening between heated or cooled spaces and unconditioned areas such as basements, attics, and crawl spaces.
Local building authorities commonly offer checklists to verify code compliance — review 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 Mountain Lakes, NJ

Preparation for blower door test in Mountain Lakes, NJ begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. Next, we inspect each room to confirm all exterior doors and windows are properly closed — including any leading to garages, basements, or other spaces beyond the thermal envelope. After ensuring the home is fully sealed, we mount the blower door fan and frame on a central exterior door and depressurize the interior to 50 Pascals for accurate testing. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors on-site. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Mountain Lakes, NJ.

Blower Door Test for Contractors in Mountain Lakes, NJ

For contractors overseeing blower door test in Mountain Lakes, NJ, most properly insulated homes can manage small on-site repairs during testing.
