RESNET Certified Inspector | Builder Focused Turnaround | Immediate Electronic Reports
Stellar Building Performance serves Indialantic, the beachside town at the east end of the Melbourne Causeway, for rebuilds, remodels and mechanical replacement work.
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. On a 0.97 square mile beachside town with a median age over 50, it is the last check before a project that has already cleared flood, wind and coastal review can close out.
What we test in Indialantic is replacement and improvement work rather than new subdivisions. The town has streamlined online permitting for exactly the categories that dominate here, HVAC, windows, doors, shutters and re-roofing, and requires emailed photographs for HVAC final.
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 is filed with the Town of Indialantic Building Department against the Florida Energy Conservation Code.

Florida Energy Code Duct Leakage Requirements
The Florida Energy Conservation Code governs every residential permit in Indialantic, and it applies to any conditioned structure built as living space.
The Town of Indialantic Building Department covers this 0.97 square mile town. Indialantic offers online permitting specifically for HVAC, windows, doors, shutters and re-roofing, which is a fair description of what the market here actually is: a built-out beachside town with a median age over 50 where the work is replacement and improvement rather than new subdivisions.
One local quirk worth planning around: the town requires emailed photographs for HVAC final inspection, including the condenser with breaker size, the air handler with breaker size, labeled panel breakers and disconnects. If you are replacing a system, budget time for that documentation step.
For envelope work, the rule that matters most is the substantial improvement threshold. Once a remodel passes 50 percent of market value, the building is treated as new for code purposes, and the air leakage requirement comes along with it.
On elevated construction, mechanical equipment has to be elevated or flood-protected. That pushes air handlers and duct distribution either into the conditioned envelope or onto elevated platforms, and any duct crossing the flow-through space below the floor is a flood-compliance problem and a leakage-to-outside problem at the same time. It is worth testing before those runs are buried.
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 Indialantic’s barrier island stock most projects are rebuilds and improvements, which means the duct system is usually being replaced, not just verified.
Ducts losing air outside the conditioned space can cause:
A clean result in Indialantic 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 Indialantic to be as easy as possible.
1.
Schedule your test
You tell us the Indialantic address and when the home will be ready. We work with the town’s online permitting flow.
2.
onsite testing
We show up at the Indialantic 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 Indialantic permit file is complete when the inspector opens it.
5.
Ready for Final Inspection approval
With the report on file, the Town of Indialantic Building Department 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 Indialantic home. The setup takes longer than the measurement itself, and nothing about it is destructive.
In Indialantic, 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 Town of Indialantic Building Department will not close it out. Being on time in Indialantic 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 Indialantic 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.
