What to expect
Ductwork includes leak sealing, balancing, redesign for additions, and replacement for collapsed or undersized trunks. Leaky ducts can waste 20-30% of conditioned air. Manual D design and static pressure testing separate quality contractors from the rest.
Illinois swings from 1,000-1,500 CDD summers to bitter winters. Equipment must handle 95°F design temperatures while sized for -5 to -10°F heating design.

Frequently asked questions
Why is one room hotter or colder than the rest?
Almost always a duct issue: leaks, undersized branch, blocked register, or unbalanced static pressure. A blower door + duct leakage test ($300-$500) identifies the actual problem instead of guessing.
Should I seal my ducts?
Yes if testing shows >10% leakage. Aerosealing typically reduces leakage 80-95% and costs $1,500-$3,000. Tape and mastic on accessible ducts are cheaper but require all-runs access.
Are flexible ducts okay?
Acceptable for short branch runs if pulled taut and supported every 4 feet. Long flex runs and tight bends drop airflow significantly — most diagnosable problems trace back to bad flex installation.
