RESNET Certified Inspector | Builder Focused Turnaround | Immediate Electronic Reports
Stellar Building Performance is proudly based in Brevard County and works throughout Malabar’s rural, large-lot neighborhoods. The Town of Malabar holds inspections on Tuesdays and Thursdays, so we plan duct leakage testing around that window instead of against it.
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 Malabar it applies to every new home with conditioned space, custom or not.
This is a low-density town of large lots south of Palm Bay, building custom homes on acreage rather than production phases. Malabar holds inspections only on Tuesdays and Thursdays, 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 Malabar Building Department.

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 Town of Malabar Building Department handles plan review, permitting and inspections for the town. Inspections run Tuesdays and Thursdays, which is the real scheduling constraint here, so we plan duct testing to land before your inspection day rather than chasing it afterward.
Why is Duct Leakage Testing Beneficial?
Large-lot homes in Malabar tend to have longer duct runs per square foot of living space, which gives leakage more places to hide.
Ducts losing air outside the conditioned space can cause:
A clean result in Malabar 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 Malabar to be as easy as possible.
1.
Schedule your test
You tell us the Malabar address and when the home will be ready. With a two-day inspection week, the envelope test has to land before the slot, not after it.
2.
onsite testing
We show up at the Malabar 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 Malabar permit file is complete when the inspector opens it.
5.
Ready for Final Inspection approval
With the report on file, the Town of Malabar 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 Malabar home. The setup takes longer than the measurement itself, and nothing about it is destructive.
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 Malabar. This includes:
Common Structures Like:
Additional Structures Like:
In Malabar, 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 — an undocumented test is an incomplete permit file, and the Town of Malabar Building Department will not close it out. Being on time in Malabar is most of the job.
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.
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.
The Town of Malabar holds inspections on Tuesdays and Thursdays only. That is a real constraint on closeout timing.
We schedule duct leakage testing far enough ahead of your inspection day that the result and documentation are in hand before the inspector arrives.
The test itself does not change. The site does. Malabar zoning runs to 1.5-acre minimums in its rural residential district, and homes here are usually custom or owner-built one at a time rather than in production phases.
We schedule single-home visits rather than batching a subdivision run.
Duct Leakage Testing Code Reference
Duct Leakage Test Florida Requirements Explained
Duct leakage testing is required in Malabar 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.
