Detect hidden air leaks and improve efficiency with professional blower door test in Chatham township, NJ. Our experts help homeowners, builders, and contractors pinpoint air leaks, improve efficiency, and comply with NJ building energy standards.

What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption 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 Chatham township, NJ makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in Chatham township, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. 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?

Homes in Chatham township, NJ are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. Satisfying this requirement in your blower door test in Chatham township, NJ helps optimize energy use and ensures you meet local building standards.

Why Do I Need A Blower Door Test?

In accordance with the IECC, the State of NJ and various local authorities require blower door test for new or remodeled residential properties. We routinely help home builders, contractors, and homeowners requiring blower door test in Chatham township, NJ for energy code compliance and permit closure. A duct leakage test is often required whenever ducts or HVAC units are found outside the building’s thermal envelope. Learn more about energy code compliance.

Homeowners benefit from blower door test in Chatham township, NJ because depressurization exposes airflow through cracks, helping identify leaks and boost efficiency. It only takes a few hours to perform a blower door test, but the long-lasting impact on comfort and efficiency is felt through NJ’ hot summers and cool winters.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Choose Tyvek or Zip Sheathing as your air barrier and check that all seams are securely taped to maintain airtightness.
Apply the correct R-value insulation and verify that it’s properly fitted to seal the whole 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 off any access points or gaps between conditioned and unconditioned spaces like attics, crawl spaces, and basements.
Local building authorities commonly offer checklists to verify code compliance — review the Philadelphia example here.
Local Energy Audits technicians carry thermal imaging devices, caulk, and spray foam to pinpoint and seal air leaks immediately./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 Chatham township, NJ

Preparation for blower door test in Chatham township, NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within the thermal envelope. Once the home is prepared, we mount the blower door fan and frame in a central exterior doorway and depressurize the building to 50 Pascals to measure air leakage precisely. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. We’re equipped with chalk, spray foam, and weatherstripping materials, so we can partner with homeowners or contractors to repair visible air leakage problems right 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 Chatham township, NJ.

Blower Door Test for Contractors in Chatham township, NJ

Most professionally insulated homes undergoing blower door test in Chatham township, NJ can resolve small issues on-site during the contractor’s visit.
