Why duct replacement & redesign matters
There is a point where cleaning and sealing stop being worth it. Flex duct from the early nineties that has gone brittle, an attic system that has been rodent-damaged along most of its length, or a layout that was undersized on the day it was installed cannot be rescued with mastic. The single most common design fault we find in this area is an undersized return: one central grille trying to feed a system that needs roughly twice the return area, which shows up as high static pressure, a filter that bows visibly toward the blower, and equipment that is being strangled while everyone blames the thermostat. Replacement is the right answer less often than the industry likes to claim, but when it is right, redesigning the return matters more than the ductwork itself.

If you are not satisfied with the result, we come back and make it right at no charge.
Benefits
What you get
Return capacity corrected
Undersized returns are the most common design fault in local homes. Fixing that is often the single biggest performance gain available.
Properly supported runs
Flex is hung at the correct interval with the correct strap width so it holds its shape instead of sagging into restrictions.
Sealed as it is built
Every joint is sealed with mastic as the system goes in, so the new ductwork starts tight rather than needing a sealing visit later.
Insulated to current values
New runs in unconditioned attic space are insulated to current values, which matters a great deal in a 140-degree Sacramento attic.
An honest scope
We frequently recommend cleaning and sealing instead. We will tell you when replacement is not the right spend.

Process
How we do it
Assess and measure
The existing layout is traced and measured, static pressure is recorded, and the returns are assessed against what the equipment needs.
Design the replacement
Trunk and branch sizes are worked out for the equipment and the rooms, with the return capacity corrected as part of the design.
Scope and fixed quote
You get the design, the materials and a fixed price in writing before anything is removed.
Remove the old system
The failed ductwork is removed and taken away rather than left in the attic, which is a common shortcut.
Install and seal as we go
New runs go in supported at the correct intervals, with every joint sealed with mastic during installation.
Balance and verify
Airflow is measured at each register, the system is balanced, and the final readings are documented for you.
Questions
Duct Replacement & Redesign FAQs
Do I actually need replacement, or just cleaning?
Most of the time, cleaning and sealing is the correct and much cheaper answer. Replacement is for duct that has genuinely failed or was badly designed. We will tell you which one you are looking at.
How long does a duct replacement take?
Most single-system homes take two to three days depending on attic access, the number of runs and whether the return needs reworking.
Can you fix the room that has never been comfortable?
That is usually a sizing, routing or return problem rather than an equipment problem, and it is exactly what a redesign addresses. We measure first so the fix is based on numbers.
Will you take the old ductwork away?
Yes. Old material is removed from the attic or crawlspace and disposed of. Leaving it in place is common practice and it is not something we do.
