RESNET Certified Inspector | Builder Focused Turnaround | Immediate Electronic Reports
Stellar Building Performance is a Florida local, family-run company serving Fellsmere and the surrounding Indian River County communities. Fellsmere issues its own permits, and with new residential construction expanding along County Road 512, we keep turnaround tight so closeout is never waiting on testing.
What Is a Duct Leakage Test?
Duct Leakage Testing is required on new residential construction in Fellsmere, and with the inland, agricultural western edge of Indian River County that usually means volume: new single-family construction on the city’s expanding growth boundary.
A duct leakage test measures how much air escapes the duct system instead of reaching the rooms it was sized for. Stellar Building Performance runs it for builders and developers working in Fellsmere and returns the report the same day, so the result is never what holds up a closing.
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. That reading is what the City of Fellsmere Building Division checks against the Florida Energy Conservation Code.

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.
The City of Fellsmere Building Division performs plan review, issues permits and conducts inspections within the city. With new single-family and townhome construction expanding along County Road 512, we keep turnaround tight so closeout is never waiting on a test report.
Why is Duct Leakage Testing Beneficial?
On a production schedule in Fellsmere, a failed duct leakage test is not one problem — it is the same problem repeated across every house on that plan.
Ducts losing air outside the conditioned space can cause:
In Fellsmere, duct leakage testing is what turns “it should be fine” into a documented number before final inspection. Passing the first time is what keeps the closeout on schedule.
How We Keep Our Services Simple and Easy
We want completing your Duct Leakage Testing in Fellsmere to be as easy as possible.
1.
Schedule your test
You tell us the Fellsmere address and when the home will be ready. A small department means direct contact, and we use it to lock the slot early.
2.
onsite testing
Our inspector arrives at the Fellsmere site and sets up. 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
The report goes out by email before we leave the Fellsmere job, documenting code compliance for the inspection file.
5.
Ready for Final Inspection approval
With the report on file, the City of Fellsmere Building Division can close out the permit and issue the certificate of occupancy.

Frequently asked questions about Duct Leakage Testing
Most duct leakage tests in Fellsmere take 30 to 60 minutes. It is quick, non-destructive, and easy to slot in before final inspection.
Simple rule of thumb: if it’s a conditioned space intended for people, it will require duct leakage testing.
By code definition, any dwelling unit permitted for residential use requires duct leakage testing in Fellsmere. This includes:
Common Structures Like:
Additional Structures Like:
In Fellsmere, 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.
Yes. If duct leakage testing is on the permit and the result is not documented, the City of Fellsmere Building Division can hold final approval until it is. That is the whole reason to use a provider who is local to Fellsmere and shows up when they said they would.
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.
No. Work does not have to stop and the building does not need to be cleared. We just need the envelope in its finished condition, with exterior doors and windows shut.
Yes. The City of Fellsmere Building Division performs plan review, issues building permits and performs inspections for construction within the city, separate from Indian River County.
Attached units are tested as individual dwelling units, which makes the party walls between them part of each unit’s pressure boundary.
New residential construction in Fellsmere includes a significant townhome component, and attached units generally take more setup than a detached home because adjacent units influence the result.
Duct Leakage Testing Code Reference
Duct Leakage Test Florida Requirements Explained
Duct leakage testing is required in Fellsmere 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.
