Air Duct Replacement Miramar, Florida

Professional Air Duct Replacement Services in Miramar, FL

Ductwork wears out over time as insulation breaks down, joints separate, and flex runs sag or tear in the attic heat. A worn duct system loses airflow before the air reaches your rooms, and patching single leaks rarely fixes the problem. Miramar Air Duct Cleaning Pro starts every project with a duct leakage test and a full attic inspection to decide whether partial or full replacement makes sense. Our crew removes the failed ductwork, installs new sealed and insulated runs sized to your equipment, and tests the system again after installation. The specific duct replacement services we offer in Miramar are listed below.

Residential Air Duct Replacement in Miramar

Many homes need full duct replacement after 20 or more years, when insulation and connections begin failing at the same time. Our technician runs a leakage test, inspects every run in the attic, and photographs damaged sections before recommending replacement. The crew removes the old trunk, branches, and boots, then installs a new layout with a sheet metal trunk, insulated flex branches, and new register boots. Every connection gets sealed with mastic, and each branch gets a balancing damper. A second leakage test confirms the improvement before we close the attic. Your home cools evenly, and far less cooled air escapes into the attic. Our air duct and dryer vent cleaning services are also available for homeowners wanting both systems cleaned at the same time.

AC Air Duct Replacement in Miramar

Cooling systems move cold air through the ducts for most of the year, and that constant temperature difference wears down insulation and vapor barriers. Our AC duct cleaning team checks the supply ducts for sweating, stained ceilings below duct runs, and wet insulation, which signal a failed vapor barrier. We replace the affected supply runs with R-8 insulated duct in an intact vapor jacket and seal every seam against humid attic air. Plenum connections at the air handler get rebuilt with new sheet metal collars and mastic. The technician measures supply air temperature at the registers before and after the replacement. Cool air reaches each room colder, and water stops dripping onto ceilings under the ducts.

Heating and Air Duct Replacement in Miramar

Heat pumps and furnace-and-AC systems push both warm and cool air through the same ducts, so the ductwork expands and contracts with each seasonal switch. Our technician inspects joints, collars, and seams for gaps that open as the metal moves between heating and cooling. We replace failed sections with sheet metal fittings joined by screws and sealed with mastic, which holds through temperature swings better than tape. For gas furnaces, the crew also confirms the supply plenum connection meets the manufacturer's clearance and material requirements. Airflow gets checked at each register in both heating and cooling mode once the system restarts. Rooms stay comfortable in both seasons through the same tight ductwork.

Air Duct Boot Replacement in Miramar

Register boots rust, separate from the drywall, or lose their insulation, which lets attic air leak straight into the room and causes vents to sweat. Our technician removes each grille and inspects the boot from inside the room and from the attic side. We cut out rusted or crushed boots and install new insulated boots sized to the register opening and the branch duct diameter. Each boot gets fastened to the framing, sealed to the drywall with mastic, and connected to its branch with a tie band and mastic seal. New grilles go back on with foam gaskets around the frame. Dust streaks around the vents stop forming, and each register delivers its full share of air.

Flex Duct Replacement in Miramar

Flex duct in hot attics loses strength as its outer jacket breaks down and its inner core tears, sags between supports, or gets crushed by foot traffic. Our air duct repair team traces each flex run and marks sections with kinks, tears, or long sags. We remove the failed flex and install new R-8 flex duct pulled tight to its full length, with no extra slack coiled in the attic. Supports go in at close intervals using wide straps that do not pinch the core. Each end gets a tie band on the inner core, a mastic seal, and a strapped outer jacket. Air travels through straight, open runs, and rooms at the end of long branches receive full airflow again.

Trunk Line Replacement in Miramar

The main trunk carries all the supply air from the air handler, so rust, open seams, or crushed sections there affect every room in the home. Our air duct installation team tests static pressure at the trunk and inspects each seam and takeoff connection. We fabricate a new sheet metal trunk sized with Manual D calculations and replace the old line in sections to limit the time your system stays off. Each takeoff gets a new collar sealed with mastic, and the trunk receives R-8 insulation wrap. The crew reconnects every branch before restarting the system. Static pressure drops back into the equipment's rated range, and every room gets stronger airflow.

Mold-Damaged Duct Replacement in Miramar

Condensation inside poorly insulated ducts soaks the inner liner or flex core, and mold grows in that damp material where cleaning cannot fully remove it. Our technician inspects the ducts with a camera and checks insulation moisture before recommending replacement over cleaning. Crews seal off the work area with plastic sheeting and run a HEPA air scrubber while removing contaminated sections. The damaged ducts get bagged in the attic before being carried through the home. We install new insulated duct with an intact vapor barrier to stop the condensation that caused the growth. Musty odors leave the home, and the new ducts stay dry through humid months.

Duct Board Replacement in Miramar

Many local homes use fiberglass duct board for plenums and trunks, and its foil facing peels as the tape on its seams loses adhesion in attic heat. Our HVAC duct cleaning team inspects the board for crushed corners, separated seams, and exposed fiberglass that can shed into the airstream. We cut new duct board panels with shiplap edges using grooving tools, then close each seam with staples and UL 181A foil tape or mastic. Plenum sections that meet the air handler get a metal collar connection sealed with mastic. Damaged board around the supply takeoffs gets rebuilt so each collar sits firmly. The rebuilt plenum holds its shape, seals tightly, and keeps fiberglass out of the air you breathe.
