Stellar Building Performance serves Indiantown, the newest municipality in Martin County, out in the western interior along SR-710 and SR-76.
What Is a Duct Leakage Test?
A duct leakage test measures how much air escapes the duct system instead of reaching the rooms it was sized for. In Indiantown it is required on every new home with conditioned living space, and given the most affordable new-construction market in Martin County by a wide margin, most of that work runs on a schedule that does not leave room for a re-test.
We handle Terra Lago by Ryan Homes, townhomes and single-family on repeating plan types alongside one-off spec work. 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 result documents compliance under the Florida Energy Conservation Code before the Village of Indiantown Building Division signs off.

Florida Energy Code Duct Leakage Requirements
The Florida Energy Conservation Code governs every residential permit in Indiantown, and it applies to any conditioned structure built as living space.
Indiantown incorporated at the end of 2017 and is the county’s newest municipality. It runs its own Village of Indiantown Building Division, so permits here do not go through the county.
Indiantown has adopted the 2023 Florida Building Code, 8th Edition, which applies to submittals made on or after January 1, 2024. It is also the most affordable new-construction market in Martin County by a wide margin. Terra Lago by Ryan Homes is building townhomes and single-family homes here at price points well below anything on the coast, which in practice means a small set of repeating plan types built over and over.
That repetition is useful. Once we have tested the first few of a plan type, we know where that plan tends to leak, and the builder can correct it upstream instead of chasing a failing test at CO.
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.
Why is Duct Leakage Testing Beneficial?
Volume builders in Indiantown do not just need a passing number, they need to know which detail moved it.
Ducts losing air outside the conditioned space can cause:
A clean result in Indiantown 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 Indiantown to be as easy as possible.
1.
Schedule your test
You tell us the Indiantown address and when the home will be ready. Once we have tested the first few of a plan type we know where it leaks, so the builder can correct upstream instead of chasing a failure at CO.
2.
onsite testing
We show up at the Indiantown address with everything needed. Registers are sealed and the duct blaster is connected to the system, which is then brought up to test pressure.
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. You get the number and, if it needs work, the reason behind it.
4.
Report delivered same day via email
Documentation is emailed the day of the test so the Indiantown permit file is complete when the inspector opens it.
5.
Ready for Final Inspection approval
With the report on file, the Village of Indiantown Building Division can close out the permit and issue the certificate of occupancy.

Frequently asked questions about Duct Leakage Testing
Typically 30 to 60 minutes for a Indiantown home. The setup takes longer than the measurement itself, and nothing about it is destructive.
In Indiantown, 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 — an undocumented test is an incomplete permit file, and the Village of Indiantown Building Division will not close it out. Being on time in Indiantown is most of the job.
It is recommended to test as close to completion as possible. Our best suggestion is to be one of the last vendors in the project before the cleaners do their final clean. We provide a pre-inspection, get ready checklist in all of our proposals that is designed to make being prepared for your duct leakage test as simple and easy as possible.
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.
Duct Leakage Testing Code Reference
Duct Leakage Test Florida Requirements Explained
Duct leakage testing is required in Indiantown 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.
