Blower Door Test in Pequannock, NJ

Protect your energy investment and verify airtightness with advanced blower door test in Pequannock, NJ. Our licensed professionals help homeowners, builders, and contractors identify air leaks, enhance comfort, and achieve NJ energy compliance.

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 a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Pequannock, NJ locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

To perform blower door test in Pequannock, NJ, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

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. 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 Pequannock, NJ, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. By meeting this standard in your blower door test in Pequannock, NJ, you can enjoy lower utility bills and peace of mind with code compliance.

Why Do I Need A Blower Door Test?

Both NJ and local jurisdictions adopt the IECC energy code, making blower door test mandatory for new and renovated residential structures. We routinely help home builders, contractors, and homeowners requiring blower door test in Pequannock, NJ for energy code compliance and permit closure. A duct leakage test may also be necessary if any ducts or HVAC systems are positioned outside the building’s thermal envelope. Learn more about energy code compliance.

Homeowners experience real energy benefits from blower door test in Pequannock, NJ. The fan’s depressurization highlights air leaks, helping identify inefficiencies that can be sealed for savings. 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.
Apply an air barrier like Tyvek or Zip Sheathing, making sure all connecting seams are properly taped and sealed.
Use properly rated insulation with the right R-value and ensure consistent coverage throughout 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.

Preparing for a Blower Door Test in Pequannock, NJ

Getting ready for blower door test in Pequannock, NJ involves turning off all heating, cooling, and exhaust ventilation systems. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside 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 occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to unconditioned areas. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. 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 Pequannock, NJ.
