Stellar Building Performance serves Merritt Island, the largest unincorporated community in central Brevard, from Sykes Creek across to the Banana River for infill, townhome and multifamily work.
What Is a Duct Leakage Test?
Duct Leakage Testing is required for new residential construction in Merritt Island — but the first thing to settle here is not the test, it is the paperwork. Merritt Island is not a true barrier island, but Brevard’s septic ordinance explicitly names it inside the barrier-island designation, so new septic installations need advanced treatment at 65 percent nitrogen removal.
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 Merritt Island, and it applies to any conditioned structure built as living space.
Merritt Island is unincorporated, so there is no city building department. Every residential permit here is issued and inspected by Brevard County Planning and Development.
One local rule catches people out. Merritt Island is a peninsula rather than a true barrier island, but Brevard’s septic ordinance explicitly names it inside the barrier-island designation, which means new septic installations require advanced treatment achieving at least 65 percent nitrogen removal. Several septic-to-sewer conversion areas are active across Merritt and Sykes Creek, with sewer service from the county’s Sykes Creek regional plant.
The new construction here is infill rather than greenfield: townhomes and multifamily on already-developed land, including a D.R. Horton townhome community in the 1,463 square foot range. Attached product is tested unit by unit with the party walls treated as part of the envelope.
Brevard County offers VuSpex virtual inspections, and the eligible list includes Insulation and Mechanical Final. That is worth thinking about: the county inspector may never be standing in the house at the exact moments the envelope and the duct system are open and visible, which raises rather than lowers the value of an independent test.
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?
Past the paperwork question, a Merritt Island home either holds its conditioned air or it does not.
Ducts losing air outside the conditioned space can cause:
A clean result in Merritt Island 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 Merritt Island to be as easy as possible.
1.
Schedule your test
You tell us the Merritt Island address and when the home will be ready. The county allows VuSpex virtual inspections on items including Insulation and Mechanical Final, which means an inspector may never be onsite while the envelope is open.
2.
onsite testing
Our inspector arrives at the Merritt Island 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. We note the problem areas while we are still standing in the house.
4.
Report delivered same day via email
Documentation is emailed the day of the test so the Merritt Island permit file is complete when the inspector opens it.
5.
Ready for Final Inspection approval
With the report on file, Brevard County Planning and Development can close out the permit and issue the certificate of occupancy.

Frequently asked questions about Duct Leakage Testing
Most duct leakage tests in Merritt Island take 30 to 60 minutes. It is quick, non-destructive, and easy to slot in before final inspection.
In Merritt Island, 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.
It can. Brevard County Planning and Development needs the documented result in the file before it closes the permit, so a missing report in Merritt Island is a stalled CO. We schedule so that does not happen.
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 Merritt Island 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.
