In most single-storey homes around Lake Charles, the ducts run through the attic, where summer temperatures climb far above the outdoor air. Flexible duct can sag, kink, get crushed or separate at a joint, and insulation can be torn or soaked. Every leak in a supply duct sends cooled air into the attic; every leak in a return pulls in hot, damp attic air.
Storms add their own wear: roof leaks soak duct insulation, and work after a storm can knock runs loose. A duct inspection looks for disconnections, crushed runs, missing insulation, condensation and whether each room gets the air it needs.

What you can check yourself
- Hold a hand at each supply vent with the system running. Note rooms with weak airflow.
- Look for water stains on ceilings below duct runs or near the air handler.
- Make sure furniture and rugs aren't blocking vents or the return grille.
- If you go into the attic, stay on the joists or walkway, and look for ducts lying flat, kinked or pulled off their fittings.
- Note dust lines around vents. They can point to leaks pulling in attic air.
The inspection
What gets checked
Disconnections and leaks
Joints pulled apart, torn inner liners and gaps at the air handler.
Sagging and kinked runs
Flexible duct needs support; a sagging run restricts airflow.
Sweating ducts
Condensation where insulation is thin or damaged.
Airflow measurement
Static pressure and room-by-room airflow show where air is lost.
Return sizing
Too little return air makes the system strain and noisy.
Repair or replace
Spot repairs for a few faults; replacement for old, brittle duct throughout.
Price ranges
Budgeting for attic ductwork repair
Figures to help you plan. Your price comes from the contractor after the system has been seen.
| Work | Typical planning range | Depends on |
|---|---|---|
| Duct inspection with airflow check | $100 – $300 | Size of the home, attic access |
| Repair or reseal several duct sections | $300 – $1,500 | Number of runs, access |
| Add or enlarge a return | $400 – $1,200 | Location, ceiling and duct work |
| Replace ductwork, single-storey home | $4,000 – $9,000 | Square footage, number of runs, materials |
Use these figures to plan, not to budget to the dollar. They are typical planning ranges, not quotes, local averages or price guarantees. Only the contractor can price your job, after looking at the equipment: size, refrigerant, access, parts and anything found on the visit all shift the number. More ranges are in the price guide.
Deciding
Ducts and a new system
If you are replacing the air conditioner, have the ducts checked at the same time. A new system on leaking or undersized ducts won't deliver what it should, and it is easier to fix both together.
See AC installation and replacement for what to ask when comparing quotes.
FAQ
Homeowners also ask
Do I need my ducts cleaned?
Duct cleaning and duct repair are different jobs. In a damp climate, repairing leaks and insulation usually matters more for comfort than cleaning. Ask the contractor what they see before agreeing to either.
Why is one room always hotter?
Common causes are a long or kinked duct run, a disconnected duct, a room with more sun and windows, or not enough return air. Airflow measurements show which.
Can sweating ducts damage the ceiling?
Yes. Condensation on poorly insulated ducts can drip onto drywall over time. Have the insulation and air leaks checked.
