What We’re Testing For
Blower door testing measures how airtight your home is—which is now required for new construction in New York State.
Using specialized equipment, we temporarily pressurize or depressurize the home to determine how much air is leaking in and out. This is reported as Air Changes Per Hour (ACH).
👉 In New York, new homes must test at 3 ACH or less to meet code requirements.
This test ensures your home:
- Meets building code compliance
- Is properly sealed
- Performs as expected for energy efficiency
Why This Matters
If your home doesn’t pass, it can delay:
- Certificate of Occupancy (CO)
- Final inspections
- Project completion timelines
Our goal is simple:
✔ Get you accurate results
✔ Help you pass code
✔ Keep your project moving forward
What We Do (And What We Don’t Do)

That means:
- ✔ We perform certified blower door testing
- ✔ We provide clear pass/fail results
- ✔ We document results for inspectors/building departments

Blower Door Testing FAQs
What is a blower door test?
A blower door test measures how much air leaks in and out of a home by using a calibrated fan system. It determines the home’s airtightness and is required for new construction in many areas.
What is the required blower door test result in New York?
New construction homes in New York must test at 3 air changes per hour (ACH) or less to meet building code requirements.
What happens if my home fails the test?
If the home exceeds 3 ACH, additional air sealing may be needed before retesting. We provide clear results so you know what needs to be addressed.
How long does a blower door test take?
Most tests can be completed in a short amount of time, depending on the size of the home and site conditions.
Do you provide repairs if the home fails?
No. We focus strictly on testing and code compliance. We do not perform repairs but can help guide you on next steps.
When should a blower door test be scheduled?
Testing is typically performed near the end of construction before final inspections and issuance of the certificate of occupancy.
