LintGuard Air Vent Cleaning repairs and seals accessible ductwork across South Florida. The work covers disconnected runs, torn and crushed flex duct, leaking joints and boots, damaged plenums, and failed connections at the air handler. Repairs are quoted after the damage is located and shown to you.
What Air Duct Repair & Sealing Includes
Disconnected and fallen duct reconnection
Flex duct works loose from collars and boots over time, especially in hot attics where tape and mastic age fast. Disconnected runs are reattached and secured so conditioned air reaches the room it was meant for.
Flex duct section replacement
Torn, crushed, or deteriorated sections of flexible duct are cut out and replaced. Inner liners that have separated from the outer jacket cannot be patched reliably, so the damaged section is replaced.
Joint and boot sealing
Leaks at joints, collars, and register boots are sealed. These connection points are the most common leak sites in local duct systems, and sealing them keeps conditioned air inside the duct.
Plenum and connection repair
The plenum takes the full output of the air handler. Gaps at the plenum and at the air handler connection leak the highest-pressure air in the system. These connections are resealed and secured.
Air Duct Repair & Sealing for Every Property Type
Attic ductwork repair
Most South Florida single-family homes run ductwork through the attic, where summer heat is extreme. Materials age faster in that heat. Attic duct repair is the most common repair call in Miami Gardens, Oakland Park, and the other single-family neighborhoods.
Duct sealing after cleaning
A cleaning visit often reveals leaks. Sealing is quoted separately and scheduled with your approval. Cleaning and sealing together address both the buildup inside the ducts and the leaks that let attic air in.
Commercial duct repair
Commercial spaces with exposed or drop-ceiling ductwork get the same repair scope: reconnect what came apart, replace what failed, and seal what leaks. Work is scheduled around business hours where the space allows.
Common Issues We Handle in South Florida
One room never cools down
A room that stays warm while the rest of the property cools is the classic sign of a disconnected or crushed duct run feeding that room. The air handler works, the air just never arrives.
High humidity indoors
Leaking return ducts can pull hot, humid attic air into the system. The air handler then fights moisture it should never have seen. Sealing the return side removes that load.
Dust around the vents
Supply leaks can stir attic dust into the airstream. Dark streaks on the ceiling around a register often trace back to a leak at the boot above it.
The system runs constantly
When a share of the conditioned air never reaches the rooms, the thermostat keeps calling for more. The system runs long cycles, and the property still feels uneven. Duct leaks are one of the causes worth ruling out.
When to Book Air Duct Repair & Sealing
When one room never matches the rest
A persistent hot or cold room is the most common reason repair calls come in. The sooner a disconnected run is reattached, the sooner the room rejoins the rest of the house.
After roof or attic work
Roofers, electricians, and insulation crews work around ductwork, and ducts get stepped on, crushed, and knocked loose. A look at the attic runs after any trade works up there catches the damage early.
When dust streaks appear at the vents
Dark edging around a register often means a leak at the boot above it. Booking the repair when the streaks show up keeps attic dust out of the airstream going forward.
Air Duct Repair & Sealing FAQ
How do I know if my ducts are leaking?
Common signs are rooms that never reach temperature, dust streaks around registers, musty attic odors when the system runs, and long run times. A visual check of the accessible ductwork confirms or rules out leaks before any repair is quoted.
Can flex duct be repaired, or does it need replacement?
Small connection failures can be resecured and sealed. Torn inner liners, crushed sections, and deteriorated jackets are replaced rather than patched, because patches on flex duct do not hold. You see the damage and the plan before work starts.
Do you replace full duct systems?
Section replacement and targeted repairs are the core of the service. If a system is at the end of its life, you get a straight answer about the condition of the accessible ductwork, and full replacement can be quoted where the layout allows it.
Will sealing my ducts cut my energy bill by a set percentage?
No fixed percentage is promised here, and any company quoting one without measuring your system is guessing. Sealed ducts keep conditioned air inside the system, which supports normal operation. The actual effect depends on how much was leaking.
What does duct repair cost?
Repairs are quoted after the damage is located. A single reconnection is a different job than replacing several runs of flex duct. Call (645) 228-6597 to schedule a look and get a quote.
