Ductwork Repair & Sealing in Lake Charles, LA
In many Lake Charles homes the ducts run through a hot attic. Every leak lets cooled air escape into the attic and pulls hot, humid air in.
Request an HVAC technicianSigns of duct trouble
One or two rooms that never cool, a lot of dust, whistling or rattling vents, or high bills with no other explanation.
Sweating vents and ducts
When cold ducts meet humid attic air, they sweat. Missing or damaged insulation lets water drip onto ceilings and grow mold. Wrapped, sealed ducts stop it.
After a storm
Hurricane winds and roof leaks can crush, soak or disconnect attic ducts. Wet duct insulation should be replaced, not dried and reused.
Sealing
Mastic and proper tape on joints and boots make a big difference. Ask whether a duct leakage test is included.
Return air
Too few or too small returns starve the system of air, raising running costs and wear. A technician can check whether your returns are sized right.
Cleaning
Duct cleaning helps after renovation dust, a storm or a mold problem. It isn't needed every year for most homes. See humidity control if mold is the issue.
Duct size and noise
Ducts that are too small make the system loud and push air too fast. A technician can measure static pressure to see whether the ducts suit the equipment.
Insulation level
Ducts in a hot attic should be well insulated. Ask what R-value your ducts have when they're inspected.
