What Is Blower Door Testing?

Certified diagnostic testing to measure building efficiency.
Reduce air leakage and meet energy code compliance.
Required in many states for new construction and major renovations to comply with energy codes.
This test identifies air leaks, improves energy performance, and helps qualify for utility rebate programs.

When Blower Door Testing is Required

Blower door testing is often required to confirm that a building is properly sealed and meets energy efficiency expectation before final approval.

It is commonly required in situations such as:

New construction projects where airtightness must be confirmed before final inspection
Major renovations or additions that affect the building envelope
Before final inspections to confirm compliance with local and national energy codes
When documentation is required for inspectors, permitting, or project approvals

In most cases, blower door testing helps identify air leaks early, reducing the risk of failed inspections, approval delays, or costly rework later in the project.

Why Blower Door Testing Matters

Poor airtightness leads to energy loss, inconsistent temperatures, higher utility bills, and code violations. Blower door testing is essential for:

Meeting local and national energy code requirements
Verifying insulation and air sealing effectiveness
Identifying hidden drafts or leaks before final inspections
Increasing comfort and indoor air quality
Reducing HVAC system strain and operating costs

Benefits of Blower Door Testing

Required for code compliance in many jurisdictions
Helps qualify for utility rebates and energy programs
Supports passing final inspections with no delays
Prevents energy waste from air leaks and gaps
Improves long-term home performance

Frequently Asked Questions

Is blower door testing required for new homes?

Yes. Most local building codes (including IECC) require blower door testing for newly built or heavily renovated homes to verify airtightness.

How long does a blower door test take?

Typically 1–2 hours, depending on the size and complexity of the property.

What does a blower door test measure?

It measures the air changes per hour (ACH) at 50 pascals of pressure—showing how much air is leaking from the home.

Will a blower door test delay my inspection timeline?

No—JB’s offers quick turnaround and can provide test results the same day to keep your project on schedule.

Can a blower door test help me get rebates?

Yes! Many energy programs and utility incentives require blower door testing as part of the qualification process.

Why do builders fail blower door or duct leakage tests?

Builders most often fail due to unsealed air gaps, poorly sealed duct connections, or missing air barriers. Common problem areas include attics, mechanical rooms, recessed lighting, and duct joints that were not properly sealed during installation.

 Trustindex verifies that the original source of the review is Google. The owner of the company is super knowledgeable and responsive. While other companies told me I didn’t qualify for rebates, Josh told me otherwise and guided me through the process. In the end he was right, I got a sizable rebate. I highly recommend working with them and  would definitely use them again for future projects.

 Trustindex verifies that the original source of the review is Google. ★★★★★ 10/10 As a builder and real estate developer, I work with a lot of consultants, and JB’s Home Energy stands out. Josh and his team supported my six-unit multifamily new construction project from the very beginning, getting involved during design and helping us evaluate and compare different energy and compliance options before we ever broke ground. They were reliable, stayed on schedule, and communicated clearly throughout the process. The blower door testing at the end was seamless and executed flawlessly. I would not hesitate to work with Josh’s team again and would recommend them without reservation.

 Trustindex verifies that the original source of the review is Google. We enjoyed working with JBHE and Tacoma Energy over the past year to obtain our maximum MassSave rebates.  They were professional, timely, pleasant, and responsible.  The home energy installation, assessment, and rebate process in Massachusetts can be complex, and these folks always made it clear and easy for us to navigate. I would highly recommend Josh and Robin! Marc Draisen Roslindale, Massachusetts
