Duct Replacement and Sealing Services in Lake Charles, LA
Duct replacement and sealing services in Lake Charles, LA stop conditioned air from escaping through leaks and outdated ductwork, improving energy efficiency and comfort while reducing strain on heating and cooling equipment.
How Do Leaky Ducts Waste Energy and Money?
Gaps, holes, and disconnected joints allow heated or cooled air to escape into attics, crawl spaces, and walls before reaching living areas.
When ductwork leaks, your HVAC system runs longer to compensate for lost air, driving up utility bills without improving comfort. Studies show that homes lose up to 30% of conditioned air through duct leaks, forcing equipment to work harder and shortening its lifespan. Rooms farthest from the air handler receive less airflow, creating hot or cold spots that frustrate residents and prompt constant thermostat adjustments.
Sealing ducts with mastic or metal tape stops these losses, directing airflow where you need it and reducing the load on your heating and cooling system. Proper sealing pays for itself through lower energy bills and fewer repair calls over the system's remaining life.
When Does Ductwork Need Complete Replacement Instead of Repair?
Systems older than fifteen years, ducts with extensive corrosion, or ductwork sized incorrectly for current equipment require full replacement.
Aging sheet metal ducts develop rust and holes that spread beyond what patching can fix. Flexible ducts degrade over time, tearing at bends and connections where tape no longer holds. If your home has been renovated or had HVAC equipment upgraded without updating ductwork, improper sizing causes airflow restrictions that reduce efficiency and shorten equipment life.
Replacing old ductwork with properly sized, sealed ducts ensures your system delivers the airflow it was designed to provide, eliminating comfort problems and maximizing energy savings.
Dalton's Air Conditioning & Heating provides air duct replacement services for systems over fifteen years old, including proper sizing and sealing to minimize leakage and improve performance.
What Happens During Professional Duct Sealing?
Technicians locate leaks using visual inspection and airflow testing, then seal joints and penetrations with approved materials.
Service begins with a thorough inspection of all accessible ductwork in attics, crawl spaces, and mechanical rooms. Technicians identify disconnected sections, damaged insulation, and areas where ducts pull away from registers or air handlers. They measure airflow at each vent to detect restrictions or imbalances caused by leaks. Once problem areas are mapped, joints and seams receive mastic sealant or metal-backed tape designed to withstand temperature changes and vibration.
Unlike standard duct tape, which dries out and fails within months, professional sealing materials maintain their bond for years, ensuring long-term performance and energy savings.
How Do Lake Charles Coastal Conditions Affect Ductwork Longevity?
Salt air, high humidity, and occasional flooding accelerate corrosion and mold growth in duct systems near the Gulf Coast.
Homes in Lake Charles experience salty moisture from gulf breezes that corrodes metal ductwork faster than inland locations. Attics without proper ventilation trap humid air that condenses on cold duct surfaces, promoting rust and mold. Flooding from hurricanes or heavy rain can submerge crawl space ducts, requiring replacement if water damage or mold contamination occurs.
Regular inspections help catch corrosion early, and replacing vulnerable sections with sealed, insulated ductwork protects your investment in a climate that challenges even well-maintained systems.
