How much does air duct replacement cost for a typical home?

Air duct replacement cost for a typical home is set only after an in-home inspection, and Boulden Brothers provides up-front, no-surprise pricing. The biggest driver is the scope of work and how accessible the existing ducts are. A technician evaluates sizing, condition, and whether replacement, targeted repairs, cleaning, or sealing is the smartest path; we start by measuring airflow so the design fits your rooms, not just the old layout. Aeroseal is a cutting-edge duct sealing technology that uses a safe, non-toxic aerosol sealant to close leaks in ductwork from the inside, which can be a lower-disruption alternative to full replacement. Our team frequently completes duct projects in the Darlington area. An on-site assessment documents your system and gives you a firm quote before any work begins.

• Key factors that shape your final price:
• Home size and total duct length to be replaced
• Number of supply and return runs, fittings, and plenums
• Duct material, insulation level, and air-sealing needs
• Attic, crawlspace, or finished-wall access complexity
