The symptoms show up in the rooms: the bedroom over the garage that never cools, the room that's fine in the morning and hopeless by 4 p.m., the house that's cool but never dry. We test duct systems with real instruments — static pressure, airflow at the registers, leakage — then seal, repair, insulate, or replace what the numbers say needs it. Ductwork is invisible when it's done right and the reason nothing else works when it's wrong.
Signs your ducts are the problem
- One or two rooms never cool no matter what
- Airflow at some registers is visibly weak
- The house is cool but stubbornly humid
- Musty smell from the vents at startup
- Visible sweating on ducts or register boots
- Whistling, rattling, or boom-bang noises in the attic
- Attic duct insulation is crushed, torn, or missing
- Rising bills since the ducts are dumping air outdoors-ish

- Testing findings: leakage scope and static-pressure results
- Repair-and-seal vs. partial vs. full replacement scope
- Attic accessibility and existing duct condition
- Return-air corrections and new boot work
- Insulation restoration to R-8 where missing
- Bundling with AC replacement vs. standalone

Testing first: where the air actually goes
Duct problems hide in plain sight because the system still 'works.' We measure static pressure at the blower, airflow at registers, and temperature where it matters, then inspect the attic runs — disconnected boots, crushed flex, torn insulation, failed connections at the air handler. The findings explain the symptoms: that bedroom starved for air, that humidity the AC can't beat.
Reported duct-cleaning estimates in the Stuart area average $287–$309 (range $276–$320), but cleaning is only right when inspection finds contamination worth removing. Leaks are the more common and more expensive problem — and no amount of cleaning fixes a duct that's dumping air into the attic or sucking attic air into your returns.
Sealing, insulating, and repairing
Most duct systems we test don't need replacement — they need their joints and boots sealed with proper mastic, their crushed runs replaced, their insulation restored, and their returns un-starved. Sealing the supply side keeps conditioned air in the house; sealing the return side keeps attic humidity, insulation fibers, and dust out of it. Both show up immediately in comfort and humidity control.
Attic insulation on the ducts matters as much as the sealing: R-8 flexible insulation on ducts running through a 130-degree attic is the difference between delivering 58°F air and delivering 65°F air. We restore crushed or missing insulation as part of every sealing job, and we check the return-air path — undersized returns are the great silent killer of cooling performance in CBS homes across Rio, Golden Gate, and Waveland.
When replacement is the right call
Some ducts are past sealing: flex runs that are crushed beyond recovery, insulation that's rodent-ruined, layouts that fight the room layout entirely, or systems paired with a new high-efficiency AC that needs different airflow than the old ducts were built for. Replacement — sized by Manual D principles, routed properly, sealed at every joint, insulated to code — is a bigger project and worth doing once, correctly.
The best time is alongside an AC replacement: the system's open, the crew's already there, and the new equipment gets ducts that can actually feed it. We'll quote both paths — repair-and-seal versus replace — with the honest tradeoffs, in writing, whenever the decision is close.

Report the findings
What's leaking, what's crushed, what's starved — with photos from the attic and plain-language explanations.
- 3
Choose the scope
Seal, repair, or replace — quoted line-item with the tradeoffs honest.

Do the work
Mastic at every joint, proper supports, insulation restored, returns corrected.
- 5
Prove the improvement
Post-work measurements at the same registers so the difference is documented, not promised.

Ductwork Services FAQs
Only when inspection finds contamination worth removing — heavy dust, mold evidence, or debris. Reported Stuart-area duct-cleaning estimates average $287–$309. What's more often worth money is sealing and insulation: leaky ducts cost you comfort and money every single day, while a duct that's merely dusty mostly isn't hurting anything.
