Signs your ducts are beyond repair
- Crushed or disconnected runs. Flex duct that's been stepped on, kinked, or pulled apart can't deliver air no matter how well it's sealed.
- Deteriorated duct board or liner. Aging materials can lose their intended shape or performance over time.
- Undersized or badly designed systems. Some duct layouts may need a closer evaluation to determine whether replacement is appropriate.
- Pest damage. Chewed-through ducts can affect duct performance and may require repair or replacement.
What a proper replacement includes
When replacement is appropriate, Cozy reviews the proposed duct layout, routing, connections, and insulation with you. The final scope is confirmed after the inspection.

Common questions
Replace or Aeroseal, how do I know?
Our inspection measures leakage and checks duct condition. If the ducts are structurally sound, sealing may be considered. If they are damaged or poorly routed, replacement may be discussed. We will explain the inspection findings and options.
How long does duct replacement take?
Your Cozy specialist will explain the project timeline after reviewing the scope, system size, and attic access.
How do new ducts fit into a whole-home plan?
Duct condition is considered alongside insulation, attic, ventilation, and HVAC findings when Cozy explains the available options.
