Air Duct Repair in Ojus - Leakage Measured, Then Priced in Writing

Fast, Reliable Air Duct Repair Across Ojus

Older Ojus ranch homes hide a specific problem: the original 1980s and 1990s flex duct retrofits are failing at the register boots, where decades of 130 – 140°F attic heat have pulled connections apart. That means raw attic air, carrying mold spores and fiberglass, leaks into your living space. Linden Air Duct Cleaning repairs and replaces ductwork in Ojus every week, and our techs know exactly what to look for in these CBS-block homes before they even open the attic hatch. If your AC runs constantly or certain rooms never cool down, call (980) 447-2498. We’ll schedule a real inspection and give you a written price before any work starts.

Ojus homeowners get a written guarantee on every repair, and if a covered repair fails, we return and fix it at no charge.

Air Duct Replacement in Ojus

Air Duct Replacement in Ojus usually means pulling out aged, sagging flex duct and running new insulated lines through the attic, then sealing every connection at the register boots and air handler. In these 1950s – 1970s ranch homes, the original metal duct was often swapped for flex during 1980s – 1990s renovations, and that material is now well past its useful life. A typical full replacement in Ojus runs $2,800 – $5,200 depending on the number of runs and attic accessibility. Partial replacement of one or two failed runs costs $450 – $900 per run, materials and labor included.

When Replacement Makes More Sense Than Repair

Flex duct that has been baking in a 130°F attic for 25 years loses its inner liner integrity. Once the liner cracks, fiberglass particles can enter the airstream. If we find more than a third of your runs are sagging, crushed, or detached at the boots, replacement is the honest answer. Re-sealing old, brittle flex is a temporary patch, not a fix.

What We Replace and What We Keep

We replace the flex runs, the register boots, and the takeoff collars where needed. We don’t upsell you on new plenums or air handlers unless there’s a real failure. The job includes static pressure verification with a manometer when we finish, so you know the system is balanced before we leave.

Ductwork Repair in Ojus

Ductwork Repair in Ojus typically targets specific failure points: detached boots, crushed flex, or torn outer jackets that leak conditioned air into the attic. Because Ojus sits on the low-elevation Miami-Dade limestone plain near the C-9 canal system, ground-level humidity stays high year-round, and any leak in a cold supply duct pulls that moist attic air into the system. Repair costs in Ojus range from $275 for a simple boot re-secure and seal to $1,100 for replacing a crushed 25-foot run with new insulated flex.

Boot Detachment at the Ceiling Register

This is the most common repair we perform in Ojus. Thermal expansion cycles in 130°F attics gradually separate the flex duct from the ceiling collar. The room never cools properly because the supply air spills into the attic instead of the living space. We re-secure the boot, seal it with mastic, and verify airflow at the register before we call the job done.

Crushed and Kinked Runs in Low-Clearance Attics

Older ranch homes in Ojus have shallow attic spaces where old flex gets kinked around truss intersections. A crushed run restricts airflow, making the air handler work harder and often leading to blower motor failure. We locate the restriction, cut out the damaged section, and splice in new flex with proper support straps.

Common Air Duct Repair Problems We See in Ojus Homes

• Detached flex boots at ceiling registers. Decades of attic heat cycling in 130 – 140°F conditions have pulled the flex away from the ceiling collar above bedrooms and living rooms. The fix is mechanical re-securing plus mastic sealing, not tape, which fails again within a few seasons.
• Sagging flex runs trapping condensation. When flex duct sags between trusses in these low-clearance ranch attics, cold conditioned air meets humid attic air at the low point. Condensation pools, mold grows inside the duct, and the musty smell comes through the vents every time the AC kicks on.
• Crushed or kinked flex behind old framing. Original 1960s truss layouts weren’t designed for flex duct retrofits. Our techs regularly find runs pinched against roof decking, dropping airflow 40 percent or more and causing uneven cooling between rooms.
• Raw attic air infiltration through torn outer jackets. South Florida’s heavy pollen load plus fiberglass particles from degraded insulation get pulled through tears in the flex jacket. The result is more dust on furniture, worse air quality, and higher electric bills as the AC runs longer to compensate.
