Need an energy test before final inspection?

New Utah building code requirements mean new homes—and some commercial projects—need a blower door test and a duct leakage test before final approval and a certificate of occupancy. We make that part easy:

Blower Door Testing

Checks the home for air leaks and confirms whether it meets the blower door requirement needed for final approval.

Duct Leakage Testing

Checks the ductwork for air leaks and confirms whether it meets the duct leakage requirement needed for final approval.

A straightforward process

Testing shouldn’t slow down your build.

Call to Schedule

Tell us the project address, test needed, approximate size, and preferred timing.

We Test

We perform the appropriate diagnostic test onsite using specialized equipment.

Get Your Results

Receive clear test results and documentation so you know what comes next. Once the project passes, we send you a certified report to submit to your building department.

Testing services

The right test for the project.

For new construction, energy-code documentation, HVAC verification, or targeted leakage diagnosis.

Residential Blower Door Testing

Checks the home for air leaks and shows whether it meets the required blower door standard.

Duct Leakage Testing

Checks the HVAC ductwork for air leaks and shows whether it meets the required duct leakage standard.

Diagnostic Testing & Retesting

If a project doesn’t pass the first time, we help identify the problem areas and return to retest after repairs are made.

Repeat-project ready

Built for builders, HVAC contractors & new construction.

You shouldn’t have to become a building-science expert just to close out a house. The testing process should be clear, responsive, and easy to coordinate.

Frequently asked questions

Building science, in plain English.

What is a blower door test?

A blower door test uses a calibrated fan installed in an exterior doorway to create a controlled pressure difference. The equipment measures the airflow needed to hold that pressure, which shows how airtight or leaky the building envelope is.

What does ACH50 mean?

ACH50 means air changes per hour at a pressure difference of 50 Pascals. It expresses how many times the home’s indoor air volume would be replaced in one hour under the standardized test condition.

What happens if the house doesn’t pass?

A failed result is information, not the end of the project. We can help clarify the result, support leakage diagnosis, and return for verification after corrections are completed.

When should I schedule testing?

Schedule when the building envelope is complete and the home can be prepared for testing, but early enough that there is still time to correct problems before the relevant inspection or project deadline.

Do you perform duct leakage testing?

Yes. Duct leakage testing measures air escaping from the HVAC duct system. Tell us the project stage and what documentation has been requested so we can confirm the appropriate test.
