What Is a Duct Leakage Test?
Duct Leakage Testing is required for new residential construction in Cocoa — but the first thing to settle here is not the test, it is the paperwork. A Cocoa mailing address does not mean the City of Cocoa, because Port St. John and Sharpes both carry Cocoa 32927 addresses and are permitted by the county.
A duct leakage test measures how much air escapes the duct system instead of reaching the rooms it was sized for. We confirm the reviewing department before scheduling, then test and report the same day.
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 documents compliance with the Florida Energy Conservation Code.

Florida Energy Code Duct Leakage Requirements
The Florida Energy Conservation Code governs every residential permit in Cocoa, and it applies to any conditioned structure built as living space.
The City of Cocoa Building Division reviews and inspects permits inside the city limits. Be careful with addresses here: a Cocoa mailing address does not mean the City of Cocoa. Port St. John and Sharpes both carry Cocoa 32927 addresses and are permitted by Brevard County Planning and Development instead. We confirm the reviewing department before scheduling.
Cocoa’s growth is heading west and northwest toward the interstate. Windward Preserve is the largest approved project in the area at up to 385 homes on roughly 200 acres, and there is workforce housing and a seven-story residential building moving through approvals in and near Cocoa Village.
One scheduling rule matters for cost: inspections requested with less than 24 hours notice incur additional fees. We book duct testing far enough ahead that a same-day scramble is not what triggers your final inspection.
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?
Whichever department reviews your Cocoa 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:
In Cocoa, 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 Cocoa to be as easy as possible.
1.
Schedule your test
You tell us the Cocoa address and when the home will be ready. Inspections requested with less than 24 hours notice carry additional fees here, so we book far enough ahead that a late request is not what holds up your final.
2.
onsite testing
Our inspector arrives at the Cocoa 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 Cocoa job, documenting code compliance for the inspection file.
5.
Ready for Final Inspection approval
With the report on file, the City of Cocoa 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 Cocoa take 30 to 60 minutes. It is quick, non-destructive, and easy to slot in before final inspection.
In Cocoa, 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.
Common Structures Like:
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 City of Cocoa Building Division can hold final approval until it is. That is the whole reason to use a provider who is local to Cocoa 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.
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.
Duct Leakage Testing Code Reference
Duct Leakage Test Florida Requirements Explained
Duct leakage testing is required in Cocoa 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.
