Air Duct Replacement in Lake Worth, FL
Torn flex, crushed runs and disconnected joints send your cooling into the attic. Replace the sections that failed.
When cleaning is not enough
Ducts in South Florida attics spend years in heat and humidity. Flexible duct has an inner liner, insulation and a vapor jacket, and each layer can fail: the jacket tears, the insulation gets wet and sags, and the inner liner collapses. Once that happens, cleaning does not restore performance and replacement is the repair.
Replacement can be partial, such as a single crushed run or a failed trunk section, or complete, such as stripping an attic of old flex and installing a new system. Rodent damage, past roof leaks and long-ago homeowner patches are common reasons older Lake Worth homes need the work.
Signs ducts need replacement
- Cooling is weak in some rooms but strong in others
- You see torn or disconnected duct in the attic
- The duct insulation is wet, stained or crumbling
- There are rodent droppings or chewed flex
- Your cooling bills are high with a newer AC
- Duct tape or old patches have failed at the joints
- Ducts are crushed under stored items or attic traffic
How duct replacement is done
Inspect the system
We trace the attic duct, test for leakage where needed and mark damaged sections.
Plan the scope
We decide between replacing a section or the whole system and plan routing improvements.
Remove and install
We remove failed duct and install new sealed and insulated runs and boots.
Verify airflow
We check supply and return airflow and make sure rooms balance.
What affects duct replacement cost
Partial repairs and full replacements are priced very differently. These factors explain why.
Scope
Replacing one run is a small job. Replacing every run and the trunk is a large one.
Material choice
Flex duct, ductboard and metal each have different cost and durability.
Attic access
Tight attic space slows removal and installation.
Related repairs
Wet insulation, damaged drywall or pest cleanup can add to the scope.
Why AC Rangel Services for duct replacement
We work under Florida license CAC1825056 and see duct failures regularly because we also clean ducts and repair AC systems. That helps us tell a duct that needs replacement from one that only needs sealing or cleaning.
We also plan duct replacement around your air handler and coil, so improvements to the ducts are matched by the equipment they serve.

Air Duct Replacement questions answered
Can I just repair a torn duct?
Sometimes. A small tear can be repaired. If the insulation is wet or the duct is brittle, replacement is more reliable.
How do I know if my attic ducts are leaking?
Signs include uneven cooling, high bills and a dusty attic near joints. A duct leakage test measures it precisely.
Does replacing ducts help my AC cool better?
It can, if leaks or restrictions were the problem. Replacing ducts on a system that is too small will not fix the cooling issue.
How long does duct replacement take?
A section can be done in a few hours. A whole-house replacement often takes a day or more.
Should I replace ducts when I replace my AC?
Often it is a good time, because access is already open and a new system should not be connected to failing ducts.
