Duct Replacement

There is a point where ductwork stops being repairable. You reach it when the insulation has gone chalky and sheds when you touch it, when the inner liner has separated in multiple runs, when a rodent has chewed a highway through the trunk, or when the original builder ran a trunk two sizes too small and every room downstream has been starving since the house was framed. Patching a system in that condition is throwing good money after bad. Three sealed seams do not fix a duct system that is 22 years old and losing a quarter of its air before it reaches a register.

What replacement actually fixes

New ductwork is a chance to correct the original build, not just copy it. We calculate what each room needs, size the trunk and branches to carry it, and lay the runs with real support and gentle turns instead of the tangle most Valley attics were built with. Undersized returns get corrected, which is the single most common defect we find in block-and-stucco homes from the 1990s and 2000s; if that is your only problem, return air upgrades may be all you need. Where the layout itself is the issue, we handle the plan through duct design and redesign so the new system delivers where the old one never could. Two-story homes and west-facing glass usually need more than an even split of air, and that is a design decision made before anything gets installed.

Why we time it with a new system

Replacement is most economical alongside a new AC installation. The equipment is already open, the plenum is coming off anyway, and you are only paying for access once. It also protects the new equipment: a high-efficiency system choked by leaking, undersized ducts will never hit its rated performance, and the warranty will not care that the ducts were the problem. If you are keeping your current system and it has years left, we will say so and scope the replacement on its own.

We will also tell you not to do this. If the runs are structurally sound and the real loss is at the seams, duct sealing costs a fraction of replacement and gets most of the benefit. If the ducts are fine but loaded with construction dust and rodent debris, duct cleaning addresses the air quality without touching the ductwork itself. If only the flex runs have failed while the metal trunk is solid, flex duct replacement is the narrower and cheaper job. Full replacement is the right call when the system is past its life, not when one part of it is annoying.
