Ductwork: sealing leaks and delivering comfort

Use these steps to plan, check and keep a record of your next actions.

• Record the affected rooms and whether closed doors change the complaint.
• Ask where ducts run relative to the conditioned enclosure.
• Request measurements distinguishing leakage, restricted airflow and heat loss.
• Clarify included repairs, materials and inaccessible sections.
• Keep before-and-after leakage, airflow, room-pressure and relevant safety results.
