Air Duct Leak Repair Sweetwater, FL

Professional Air Duct Leak Repair Services in Sweetwater

Foil tape that has peeled or cloth duct tape that has dried out no longer holds duct joints tight. Our duct repair technicians bring testing and sealing equipment to every job. We begin with a walkthrough of your property and a visual check of accessible ducts. Then we patch torn sections and wrap the joints with UL-rated foil tape. We also seal the boot connections where ducts meet each room. Once the repairs are done, we retest the system to confirm the leaks are sealed. The specific duct leak repair services we handle for homes and businesses are listed below.

AC Duct Leak Repair in Sweetwater

Supply ducts carry cooled air under positive pressure, so every gap in a supply run pushes cooling you paid for straight into the attic. Our technician tests airflow at each register and pressurizes the system to find which supply runs lose the most air. We trace those runs through the attic with a thermal camera, which shows cold spots where air escapes at seams and takeoffs. Each leak gets cleaned of dust and old tape, then sealed with a thick coat of water-based mastic. Gaps wider than a quarter inch get fiberglass mesh tape embedded in the mastic before the final coat. Rooms at the end of long supply runs cool faster, and the AC shuts off sooner each cycle. Dryer vent camera Inspection can also help identify hidden blockages, damaged sections, or disconnected joints within a dryer exhaust system.

Return Duct Leak Repair in Sweetwater

Return ducts work under negative pressure, so leaks pull in hot attic air, insulation fibers, and dust instead of room air. We check the return plenum, the return trunk, and each return grille with a smoke pencil while the system runs. Smoke drawn into a seam or joint marks the exact leak city. We seal return joints with mastic and mesh tape and seal the return box to the surrounding framing and drywall. Closet returns built on a wood platform get every framing joint sealed, since those cavities often leak the most. Filter racks with gaps get fitted with gaskets so unfiltered air stops slipping past the filter. The system pulls cleaner air from your rooms, and indoor humidity and dust levels drop.

Plenum Leak Sealing in Sweetwater

Plenums connect directly to the air handler, where air pressure is highest, so small gaps at plenum seams leak large volumes of air. Our team inspects the supply and return plenums and the flange joints at the air handler cabinet. We tighten loose fasteners, seal the flanges with mastic, and seal the cabinet connection with UL 181 foil tape. Duct board plenums with crumbling edges get rebuilt or repaired before sealing. Access panels on the air handler get fresh gaskets where the old ones have hardened. A pressure reading at the plenum confirms the seals hold at full blower speed. Air leaves the air handler and enters the duct system instead of escaping into the closet or attic, helping maximize AC efficiency by keeping conditioned air inside the duct system.

Duct Joint and Seam Sealing in Sweetwater

Cloth-backed duct tape dries out in attic heat, and the joints it once sealed slowly open over the years. Our technician walks every accessible duct run and inspects each joint, elbow, and takeoff for gaps and loose tape. We remove failed tape, clean the metal, and fasten loose joints with sheet metal screws before sealing. Each joint gets a brushed coat of mastic that stays flexible through heating and cooling cycles. Takeoff collars at the trunk get sealed around their full circumference. A follow-up smoke test along each run confirms no joint still pulls or pushes air. Airflow at the registers improves throughout the house, and the sealed joints hold for the long term.

Flex Duct Leak Repair in Sweetwater

Flex duct leaks where the inner core tears, where it slips off its collar, or where the vapor jacket splits and lets air escape into the insulation. Sweetwater Air Duct Cleaning Pro inspects each flex run for torn cores, loose connections, and inflated or damp jackets that signal hidden leaks. We cut out torn sections and join new insulated flex with a sheet metal coupling, tie bands, and mastic. Loose ends get pulled back over their collars, secured with a tie band on the inner core, and sealed. The outer jacket gets pulled over each connection and taped so humid attic air stays off the inner core. Air reaches each register at full volume, and condensation stops forming on the flex jacket. Whole home vent cleaning can also help remove accumulated dust and debris from ventilation pathways throughout the home, supporting cleaner airflow from room to room.

Register Boot Leak Sealing in Sweetwater

Gaps between the register boot and the drywall let attic air leak into rooms and conditioned air leak into the ceiling. We remove each register and check the boot edge for gaps and dust streaks. We seal the boot to the drywall from inside the room with mastic or a foam sealant rated for the gap size. From the attic, the crew seals the seam where the boot meets the branch duct. Insulation gets restored over the boot so the metal stays above the dew point. Every register gets reinstalled with a foam gasket behind its frame. Dust streaks around vents stop forming, and ceilings around the registers stay dry.

Duct Leakage Testing in Sweetwater

Leaks rarely show themselves, and a visual inspection can miss gaps hidden under insulation or behind walls. Our crew seals every register and return, connects a calibrated fan and pressure gauge to the system, and pressurizes the ducts to a standard test pressure. The gauge reports total leakage in cubic feet per minute, and a house pressure test can add a separate reading for leakage to the outside. We use the result to decide whether targeted sealing will fix the problem or whether damaged runs need replacement. You receive the test numbers in writing for your records. The test turns a guess into a measured starting point with a clear before-and-after comparison. Bathroom exhaust duct cleaning can also help clear dust, lint, and buildup from bathroom exhaust pathways so air moves freely through the duct.

Duct Board Leak Repair in Sweetwater

Fiberglass duct board breaks down at its seams and edges over time, and the foil tape that holds it together peels in attic heat. Our technician inspects duct board plenums and trunks for peeling tape, crushed corners, and separated seams. We clean and dry each failed seam, then reseal it with UL 181A pressure-sensitive foil tape and a layer of mastic. Crushed or water-damaged sections get cut out and replaced with new duct board fabricated on site. Exposed edges get sealed so loose fiberglass stops entering the airstream. The duct board holds its shape and seal, and the system stops pulling fibers into the house.
