Accessibility
Exposed runs in basements/attics cost less; in-wall or ceiling adds 50-100%
System design
Proper sizing and layout require engineering; poor design wastes energy
Insulation
Insulated ductwork adds $3-8/LF but required for attic/unconditioned space

Frequently Asked Questions
How much does new ductwork cost?
New ductwork costs $5,000-$10,000 for a complete 2,000 sq ft home system. Single room additions run $1,000-$2,500. Replacing existing ductwork costs $3,000-$7,000. Ductwork is often 20-40% of a new HVAC system cost.
How long does ductwork last?
Ductwork lasts 25-40 years if properly maintained. Flexible duct lasts 15-25 years. Metal duct lasts 30-50 years. Signs of replacement need: visible damage, excessive dust, uneven temperatures, high energy bills, or age over 20 years.
Is it worth replacing old ductwork?
Yes, if ducts are damaged, leaking (25-40% of air loss is common), undersized, or causing poor air quality. New sealed ductwork can reduce energy bills 20-30%. Often done alongside HVAC replacement for best results.
What is the best type of ductwork?
Rigid sheet metal is most durable and efficient. Spiral/round duct has better airflow and less noise. Flexible duct is cheapest but has more air resistance and shorter lifespan. Combination systems use rigid for main runs, flex for final connections.
