RESNET Certified Inspector | Builder Focused Turnaround | Immediate Electronic Reports
Stellar Building Performance serves Palm Shores, the small lagoon-front town between Melbourne and Suntree, for custom residential and waterfront infill construction.
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 Palm Shores it applies to every new home with conditioned space, custom or not.
This is a 0.60 square mile lagoon-front town wedged between Melbourne and Suntree, building custom and waterfront infill, with no production subdivision here. The town building official’s charter explicitly covers coastal construction and environmentally sensitive lands, and much of the buildable land sits inside the county’s 197-foot lagoon septic buffer, so the testing window is narrower than it looks.
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. Results are documented against the Florida Energy Conservation Code for the Town of Palm Shores.

Florida Energy Code Duct Leakage Requirements
The Florida Energy Conservation Code governs every residential permit in Palm Shores, and it applies to any conditioned structure built as living space.
Palm Shores is about 1,200 residents in 0.60 square miles sitting directly on the Indian River Lagoon, and it maintains its own building official through the Town of Palm Shores rather than deferring to the county.
That official’s charter explicitly covers coastal construction and environmentally sensitive lands, which tells you what drives approvals here. In a riverfront town this small, much of the buildable land sits inside the county’s 197-foot lagoon buffer, where new septic installations must use advanced treatment systems achieving at least 65 percent nitrogen removal under the county’s 2018 ordinance.
Everything we test in Palm Shores is custom or infill. There is no production subdivision here, which means each house is its own envelope rather than a repeating plan type, and the test is worth scheduling before the drywall is closed up rather than after.
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?
On custom work in Palm Shores the owner is usually standing right there when the number comes back, so it is worth getting right the first time.
Ducts losing air outside the conditioned space can cause:
For Palm Shores projects the test does two jobs at once: it satisfies the Town of Palm Shores and it tells the builder whether the assembly actually performed the way it was drawn.
How We Keep Our Services Simple and Easy
We want completing your Duct Leakage Testing in Palm Shores to be as easy as possible.
1.
Schedule your test
You tell us the Palm Shores address and when the home will be ready. We coordinate directly with the town office.
2.
onsite testing
We show up at the Palm Shores 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. If it is over, we identify where it is going rather than just handing you a fail.
4.
Report delivered same day via email
Everyone on the Palm Shores project team gets the signed report the same day, not on the next visit.
5.
Ready for Final Inspection approval
With the report on file, the Town of Palm Shores 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 Palm Shores home. The setup takes longer than the measurement itself, and nothing about it is destructive.
In Palm Shores, 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, the Town of Palm Shores can hold final approval until it is. That is the whole reason to use a provider who is local to Palm Shores and shows up when they said they would.
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.
In most cases, no. Other trades can keep working in Palm Shores while we test — we only need the openings closed and the house in its final configuration.
Duct Leakage Testing Code Reference
Duct Leakage Test Florida Requirements Explained
Duct leakage testing is required in Palm Shores 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.
