RESNET Certified Inspector | Builder Focused Turnaround | Immediate Electronic Reports
Stellar Building Performance is proudly based in Brevard County and regularly tests the acreage homesites across Grant-Valkaria. The town office runs a four-day week and is closed Fridays, which we build into the schedule when a project is heading for closeout.
What Is a Duct Leakage Test?
Every new home in Grant-Valkaria with conditioned living space has to be tested. Grant-Valkaria is a rural town of large parcels between Palm Bay and Micco, and the work here is custom and scattered-lot construction.
A duct leakage test measures how much air escapes the duct system instead of reaching the rooms it was sized for. On one-off builds there is no second house to learn from — each duct system is its own, which is why we would rather test before things are closed up than after.
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 documents compliance with the Florida Energy Conservation Code for the Town of Grant-Valkaria 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 Grant-Valkaria Building Department reviews and inspects permits for the town, on a Monday through Thursday schedule. Most work here is custom homes on acreage rather than repeated plan types, so each project gets its own visit and its own documented envelope result.
Why is Duct Leakage Testing Beneficial?
On custom work in Grant-Valkaria the owner is usually standing right there when the number comes back, so it is worth getting right the first time.
Ducts losing air outside the conditioned space can cause:
In Grant-Valkaria, 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 Grant-Valkaria to be as easy as possible.
1.
Schedule your test
You tell us the Grant-Valkaria address and when the home will be ready. A four-day town week means a Friday problem waits until Monday, so we test with room to spare.
2.
onsite testing
Our inspector arrives at the Grant-Valkaria 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 Grant-Valkaria job, documenting code compliance for the inspection file.
5.
Ready for Final Inspection approval
With the report on file, the Town of Grant-Valkaria Building Department can close out the permit and issue the certificate of occupancy.

Frequently asked questions about Duct Leakage Testing
Most duct leakage tests in Grant-Valkaria 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 Grant-Valkaria. This includes:
Common Structures Like:
Additional Structures Like:
In Grant-Valkaria, 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 Town of Grant-Valkaria Building Department can hold final approval until it is. That is the whole reason to use a provider who is local to Grant-Valkaria 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.
The Town of Grant-Valkaria runs a four-day week, open Monday through Thursday and closed Fridays.
We factor that into scheduling so a project heading into closeout does not stall against a town office that is closed.
It affects scheduling more than method. The town charter is built around preserving a rural, low-density character, so work here is one custom home at a time rather than repeated plan types.
Each home gets its own visit and its own envelope result, with no assumptions carried over from a previous build.
Duct Leakage Testing Code Reference
Duct Leakage Test Florida Requirements Explained
Duct leakage testing is required in Grant-Valkaria 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.
