Air Duct Repair & Replacement at a Glance
Understanding HVAC & Air Ducts
Leaky or disconnected ductwork can lose a significant share of heated or cooled air before it ever reaches a room — meaning your HVAC system works harder (and costs more to run) than it should, even if the equipment itself is fine.
Dust, debris, and even pest activity can accumulate inside ductwork over time and get redistributed through your home every time the system runs, which is why duct condition affects indoor air quality as much as it affects energy efficiency.
Repair versus full replacement usually comes down to the extent of damage and the age of the existing ductwork — a professional inspection is the only reliable way to know which makes sense for a given home.

FAQ
How much does air duct repair & replacement cost? +
Cost depends on the size of your home and the scope of the work. We provide a free, no-obligation inspection and give you an exact quote before anything begins — no surprises.
How long does the work take? +
Most jobs are completed in a single day. Larger or more involved projects may take longer, which we'll confirm during your free inspection.
Do I need to be home during the work? +
You don't need to stay in the work area itself, but we do ask that someone is available at the start and end of the appointment. Our crew works cleanly and keeps you updated throughout.
Are you licensed and insured? +
Yes — Attic Star is fully licensed, bonded, and insured, and has served Bay Area homeowners for over 25 years.
How do I know if my ducts need repair versus full replacement? +
It depends on the extent of damage, leaks, and the age of your existing ductwork. A professional inspection is the most reliable way to know which makes sense — we'll give you a clear recommendation either way.
Can bad ductwork really affect my energy bills that much? +
Yes — leaky or disconnected ducts can lose a meaningful share of conditioned air before it reaches your rooms, meaning your system runs longer and harder than it should to reach the same comfort level.
Does duct condition affect indoor air quality, not just efficiency? +
It can — dust, debris, and allergens inside ductwork get redistributed through your home every time the system runs, so duct condition affects both efficiency and what you're breathing.
