Stellar Building Performance is a Florida family-run company providing energy code testing across Okeechobee County, including Fort Drum. Fort Drum is unincorporated, so permits and inspections run through the Okeechobee County Building Department.

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 Fort Drum, it is the last check before a new home or conditioned addition can close out with the Okeechobee County Building Department.

Fort Drum is an unincorporated community on US 441 about 20 miles north of the City of Okeechobee, between Okeechobee and Yeehaw Junction, and the namesake of the Fort Drum service plaza on Florida’s Turnpike. It grew up as cattle country after the Seminole Wars and is still rural today.

Registers are sealed and a calibrated fan pressurizes the system to 25 Pascals, reporting the result as CFM25 per 100 square feet of conditioned floor area. The result is filed with the Okeechobee County Building Department 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.

Fort Drum is unincorporated, so the Okeechobee County Building Department issues the permit and handles the inspections. The county runs the department under contract with SAFEbuilt, offers online permitting and inspection requests, and has a permit technician review construction documents for completeness before a submittal is accepted, so an incomplete package costs time before it ever reaches plan review.

Why is Duct Leakage Testing Beneficial?

Fort Drum sits in Florida’s hot, humid Climate Zone 2, which is unforgiving about air and moisture, and the duct system is where conditioned air goes missing.
Ducts losing air outside the conditioned space can cause:

  • Higher Energy and Utility Costs
  • Uncomfortable indoor temperatures
  • Humidity and condensation issues
  • Reduced HVAC performance

For Fort Drum projects the test does two jobs at once: it satisfies the Okeechobee County Building Department and it tells the builder whether the assembly actually performed the way it was drawn.

How We Keep Our Services Simple and Easy

We want completing your Duct Leakage Testing in Fort Drum to be as easy as possible.

1.

Schedule your test

You tell us the Fort Drum address and when the home will be ready. Okeechobee County is a longer drive for us than our coastal work, so put the test on our calendar as early as you can and we will line it up with your final inspection.

2.

onsite testing

We show up at the Fort Drum address with everything needed. Registers are sealed and the duct tester 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

Everyone on the Fort Drum project team gets the signed report the same day, not on the next visit.

5.

Ready for Final Inspection approval

With the report on file, the Okeechobee County Building Department can close out the permit and issue the certificate of occupancy.

Frequently asked questions about Duct Leakage Testing

How long does a Duct Leakage Test take in Fort Drum?

Typically 30 to 60 minutes for a Fort Drum home. The setup takes longer than the measurement itself, and nothing about it is destructive.

What kind of buildings in Fort Drum need Duct Leakage Testing?

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 Fort Drum. This includes:

Common Structures Like:

  • Single Family Homes
  • Duplexes
  • Townhomes
  • Apartments

Additional Structures Like:

  • Guest Houses
  • Pool Houses
  • Additions
  • Newly conditioned garages
  • Workshops
  • Mother-in-law suites
What kind of duct systems in Fort Drum need to be tested?

In Fort Drum, 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.

Can a missing Duct Leakage Test stop me from getting my CO in Fort Drum?

Yes. If duct leakage testing is on the permit and the result is not documented, the Okeechobee County Building Department can hold final approval until it is. That is the whole reason to book the test early, with a provider who shows up when they said they would.

Do we test at rough-in or after construction in Fort Drum?

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.

Do we need to stop work and get everyone out of the building for testing?

In most cases, no. Other trades can keep working in Fort Drum while we test — we only need the openings closed and the house in its final configuration.

Who permits construction in Fort Drum?

Okeechobee County. Fort Drum is unincorporated, so the permit and the inspections run through the Okeechobee County Building Department. We schedule the test against the county inspection date.

Is Fort Drum too far out for testing?

No. Fort Drum is part of our Okeechobee County service area. Okeechobee County is a longer drive for us than our coastal work, so put the test on our calendar as early as you can and we will line it up with your final inspection.

Duct Leakage Testing Code Reference

Duct Leakage Test Florida Requirements Explained

Duct leakage testing is required in Fort Drum 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.
