Blower Door Test in West Conshohocken, NJ

Improve insulation performance and meet energy code requirements through thorough blower door test in West Conshohocken, NJ. Our certified technicians assist homeowners, builders, and contractors in detecting hidden air leaks, boosting comfort, and ensuring full compliance with NJ energy codes.

What Is A Blower Door Test?

A blower door test determines the air changes per hour of a house or building, ensuring proper ventilation as old air cycles out and fresh air flows in. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in West Conshohocken, NJ helps discover hidden leaks early so homeowners can save energy, enhance comfort, and improve home resilience.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in West Conshohocken, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.

What Is A Passing Blower Door Test Score?

In West Conshohocken, NJ, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. Achieving compliance in your blower door test in West Conshohocken, NJ helps improve energy efficiency and meet all local code mandates.

Why Do I Need A Blower Door Test?

The State of NJ and local municipalities have implemented the IECC code, which mandates blower door test on new and remodeled residential homes. We regularly provide blower door test in West Conshohocken, NJ for home builders, contractors, and homeowners working to meet local code requirements and close permits. If any part of the HVAC system or ductwork sits beyond the building’s thermal envelope, a duct leakage test may be required. Learn more about energy code compliance.

There are many benefits of blower door test in West Conshohocken, NJ for homeowners. When the fan lowers indoor pressure, leaks become visible, allowing for easy identification of inefficiencies and energy-saving opportunities. Taking only a few hours, a blower door test creates a long-lasting impact by improving comfort, performance, and efficiency in NJhomes.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Use a reliable air barrier like Tyvek or Zip Sheathing and make sure all seams are securely taped.
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.
Seal cracks and openings between conditioned interiors and unconditioned areas such as crawl spaces, attics, and basements.
Many cities provide compliance checklists through their building departments — see the Philadelphia version here.
Local Energy Audits arrives fully equipped with thermal imaging, caulk, and spray foam to detect and seal leaks in one visit./li>
Typically, over 90% of the time we record a passing score in two hours and handle all permit-related documentation.

Preparing for a Blower Door Test in West Conshohocken, NJ

We begin blower door test in West Conshohocken, NJ by switching off the HVAC system and shutting down all exhaust fans throughout the home. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces outside the thermal envelope. With all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with West Conshohocken, NJ energy standards.
