RESNET Certified Inspector | Builder Focused Turnaround | Immediate Electronic Reports
Stellar Building Performance is a Florida local, family-run company serving builders throughout Vero Beach and Indian River County. Inside the City of Vero Beach, building permits are issued by the Indian River County Building Division rather than a city department, and we document results to match what the county reviewer expects.
What Is a Duct Leakage Test?
Before anything gets tested in Vero Beach, one question has to be answered: who holds the permit. Vero Beach has no city building department, so the county is the authority even inside the city, while the city’s own Planning and Development handles site plan and zoning first.
Vero Beach is the county seat, with barrier island construction alongside mainland infill, and the work runs to custom coastal work and mainland infill. A duct leakage test measures how much air escapes the duct system instead of reaching the rooms it was sized for.
Registers are sealed and a calibrated duct blaster pressurizes the system to 25 Pascals, reporting the result as CFM25 per 100 square feet of conditioned floor area. The report goes to whichever department is actually reviewing, documented under the Florida Energy Conservation Code.
About Me
Before founding Stellar Building Performance, I spent more than 4 years overseeing residential energy code compliance services across two branches covering Southeast Florida including Vero Beach for a national engineering firm, supporting builders, contractors, and developers on projects ranging from single-family homes, to developments, to multifamily construction.

Florida Energy Code Duct Leakage Requirements
A duct test is required here whenever any part of the duct system or the air handler sits outside the conditioned space. Total leakage must be no more than 4 CFM25 per 100 square feet of conditioned floor area, or 3 CFM25 per 100 square feet at rough-in where the air handler is not yet installed. Where every duct run and the air handler are inside the thermal envelope, the code does not require a test at all.
Inside the City of Vero Beach, building permits are issued by the Indian River County Building Division rather than a city department, with the City handling site plan and zoning approval first. We test both mainland production work and elevated barrier island construction, where ducts and air handlers behave very differently from slab-on-grade homes.
Why is Duct Leakage Testing Beneficial?
Whichever department reviews your Vero Beach permit, the number they want is the same one — and what it tells you about the house matters beyond the inspection.
Ducts losing air outside the conditioned space can cause:
A clean result in Vero Beach means the file is complete and nobody is making a second trip. A failure caught early means it is still cheap to fix.
How We Keep Our Services Simple and Easy
We want completing your Duct Leakage Testing in Vero Beach to be as easy as possible.
1.
Schedule your test
You tell us the Vero Beach address and when the home will be ready. We confirm which desk the report goes to before we schedule.
2.
onsite testing
Registers are sealed and the duct blaster is connected to the system, which is then brought up to test pressure. We work around whoever else is still on site in Vero Beach, so nobody has to clear out.
3.
Diagnostics and Measurements
We measure total duct leakage in CFM25 per 100 square feet and compare it against the limit for the test stage. If it is over, we identify where it is going rather than just handing you a fail.
4.
Report delivered same day via email
Documentation is emailed the day of the test so the Vero Beach permit file is complete when the inspector opens it.
5.
Ready for Final Inspection approval
With the report on file, Indian River County Building Division can close out the permit and issue the certificate of occupancy.

Frequently asked questions about Duct Leakage Testing
Budget half an hour to an hour on site in Vero Beach, depending on the size of the house. Nothing is drilled, cut or removed.
In Vero Beach, duct leakage testing is required for new residential buildings where any part of the duct system or the air handler sits outside the conditioned space. That covers most homes with ducts in an attic, a garage, a crawlspace, or a soffit chase. If every duct run and the air handler are inside the thermal envelope, the code exempts the system from testing.

Additional Structures Like:
Either one is allowed. A rough-in test is run before the drywall closes the system up, which is the better moment to catch a problem because the ducts are still reachable. A postconstruction test is run near the end, once the air handler is in and the home is approaching final inspection. The limit is 4 CFM25 per 100 square feet in both cases, except at rough-in without the air handler installed, where it tightens to 3.
Yes. If duct leakage testing is on the permit and the result is not documented, Indian River County Building Division can hold final approval until it is. That is the whole reason to use a provider who is local to Vero Beach and shows up when they said they would.
Not 100% complete in every cosmetic detail, but complete enough that the building envelope is representative of the finished home. Windows, doors, and penetrations should already be installed and sealed before testing takes place. We generally recommend having your inspection within a few days of requesting final inspection.
Usually not. The test runs while the crew keeps going; what matters is that the building is buttoned up the way it will be at handover.
The Indian River County Building Division, not a city department. The county has jurisdiction within the unincorporated county and within the City of Vero Beach.
The City’s Planning and Development Department handles site plan and zoning approval first, then the county issues the building permit and performs inspections.
The procedure is the same, but elevated construction behaves differently. Vero Beach city limits straddle both the mainland and the barrier island.
On elevated homes, ducts and air handlers often sit in semi-conditioned or unconditioned space within or below the floor system, which changes where leakage shows up and often makes duct leakage testing the more revealing of the two.
Duct Leakage Testing Code Reference
Duct Leakage Test Florida Requirements Explained
Duct leakage testing is required in Vero Beach under R403.3.3 of the 2023 Florida Building Code, Energy Conservation, Eighth Edition, which calls for ducts to be pressure tested at 25 Pascals either at rough-in or after construction.
The limits live in R403.3.4. Total leakage must be no more than 4 CFM25 per 100 square feet of conditioned floor area on a postconstruction test, and the same 4 CFM25 on a rough-in test where the air handler is installed. If the air handler is not in place at rough-in, the limit tightens to 3 CFM25 per 100 square feet.
There is a real exception: no duct test is required where the ducts and air handlers are located entirely within the building thermal envelope. Homes on the performance path under R405 are handled differently again, and are tested against the duct leakage rate assumed in the energy calculation.
We keep the full code language, including the complete text of R403.3.3, R403.3.4 and the R405 provisions, on our main duct leakage page: read the full Florida duct leakage code references.
