The Blower Door Test — Paterson, NJ
The blower door test is a standardized diagnostic that measures how leaky a home’s thermal envelope is. The result is expressed as air changes per hour at 50 Pascals (ACH50) — a single number that tells you how many times per hour the full interior air volume is being exchanged with outdoor air under a controlled pressure.
For Paterson, NJ homes, ACH50 is what your building inspector uses to determine whether the house meets IECC requirements. Too leaky and you fail; too tight and you may need mechanical ventilation.
What Our Clients Say
Saima Faiz — October 2024
I recently contacted Local Energy Audits for help with a suspected duct leak. From the start, they asked all the right questions and even requested pictures to better understand the situation. Based on the information I provided, they recommended a specific service, which, surprisingly, they didn’t even sell. They didn’t charge me anything for their time, and the advice they gave was invaluable. Their honesty, professionalism, and genuine desire to help really stood out. I highly recommend them.
Max Young — September 2024
Frustrated with my high electric bills — despite an efficiency drive in lighting and appliances — I suspected HVAC was to blame but didn’t know where to start. Research suggested an energy audit, and I’m very happy I chose Local Energy Audits. Ori was extremely professional, thorough, and on-time. After the blower door test, he walked every room with me, patiently reviewing leaks and possible fixes. Particularly given the new federal tax credits, I found the price extraordinarily reasonable. Highly recommend.
Robin Rafkin — June 2024
I had called numerous companies and had numerous individuals to our house. No one could figure out the issues. Ori explained everything and fixed the issues. He and his crew are wonderful!

How Is the Blower Door Test Conducted in Paterson?
For your blower door test in Paterson, NJ, the technician ensures all exterior doors and windows are sealed and interior doors stay open. An adjustable aluminum frame with a fabric panel is installed in a central exterior door. A calibrated fan depressurizes the home to 50 Pascals — roughly the force of a 20 mph wind pressing on the house.
As air is drawn out, outside air rushes in through unsealed spaces. A manometer measures fan airflow against the pressure differential, and the result converts to air changes per hour (ACH).
What Score Do You Need to Pass in Paterson?
Most of Paterson, NJ enforces the 2015 IECC, which sets the pass threshold at 3 ACH50 or lower. Some jurisdictions in Passaic County have adopted newer codes with slightly different numbers, but 3 ACH50 remains the working target for most residential projects.
Homes built with modern air barrier systems (Tyvek, ZIP sheathing with taped seams, well-installed insulation) regularly pass under 2 ACH50. Older homes — anything built pre-2000 in Paterson — often land between 5 and 10 ACH50 without retrofit work.
Why Do I Need a Blower Door Test in Paterson?
NJ enforces the IECC, requiring blower door tests on residential construction and substantial renovations. We regularly run tests for builders, HVAC contractors, and homeowners in Passaic County needing to meet code and close out permits. A duct leakage test may also be required if ductwork sits outside the thermal envelope.
Strategies for Passing in Paterson
- Plan the air barrier before framing starts. Catching leaks on paper is free; catching them during test day is expensive.
- Use a quality housewrap (Tyvek, Typar, or equivalent) and tape every seam — including around windows, doors, and penetrations.
- ZIP sheathing with factory-taped seams is increasingly popular in Passaic County new construction for good reason: it delivers excellent blower door numbers.
- Insulation R-values for NJ’s climate zone must be correct — undersized insulation won’t fail the blower door but will hurt downstream energy performance.
- Caulk or foam every penetration in exterior walls (plumbing, electrical, ductwork, dryer vents).
- Don’t forget attic hatches, recessed lights, and basement rim joists — common failure points.
- Reference the air barrier checklist for your inspector’s jurisdiction.
- We bring caulk, spray foam, and weatherstripping to every test in Paterson so small leaks can be addressed on the spot.
- More than 90% of our tests pass on the first try, under two hours.
What to Expect on Test Day in Paterson
On the day of your blower door test in Paterson, NJ, we’ll ask you to shut off heating, cooling, and exhaust fans. When our tech arrives, they’ll walk the house to make sure every exterior opening is closed and every interior door is open.
The blower door frame goes into a central exterior door, the calibrated fan depressurizes the home to 50 Pascals, and we use a thermal imager to locate leak points. We carry caulk, spray foam, and weatherstripping — so if we find leaks that are easily addressable, we can seal them on-site and retest. Most Passaic County appointments wrap up in 1–2 hours.
Contractor-Friendly Blower Door Testing in Paterson
We’ve run thousands of blower door tests across Passaic County for production builders, custom homebuilders, and HVAC subs. Our approach: bring the right gear, work fast, and carry caulk and foam so we can fix small issues in real time rather than making you reschedule. 90%+ first-try pass rate, same-day documentation, and pricing that works for production schedules.

Frequently Asked Questions
What ACH50 do I need to pass the blower door test in Paterson, NJ?
Under 2021 IECC (via the NJ Uniform Construction Code, N.J.A.C. 5:23), the pass threshold is 3 ACH50 or lower for most residential construction. Newly built homes in Paterson with attention to air sealing typically achieve 1.5-2.5 ACH50.
How long does a blower door test take in Paterson?
Most blower door tests in Paterson take 1-2 hours total, including setup, testing, leak identification with thermal imaging, and documentation. Minor sealing work, if needed, can often be done on-site.
Does my NJ home need mechanical ventilation?
If your Paterson home tests at 3 ACH50 or tighter (which current code requires), 2021 IECC (via the NJ Uniform Construction Code, N.J.A.C. 5:23) also requires balanced mechanical ventilation per ASHRAE 62.2 to maintain indoor air quality. This is typically an ERV or HRV system sized to the home.
What insulation R-values are required in Climate Zone 4A?
For Paterson (4A (Mixed-Humid)): R-49 ceilings, R-20 walls (or R-13 + R-5 continuous), and R-10 continuous or R-13 cavity for basement walls per 2021 IECC (via the NJ Uniform Construction Code, N.J.A.C. 5:23). These minimums drive what your home needs to pass overall energy code.
