What Ductwork Replacement Includes

Ductwork replacement removes the existing duct system and installs a new one designed for the home. Nolan Air measures room-by-room loads, sizes each supply run and the return system to the equipment, and lays out the trunk and branches for the shortest, straightest paths the attic allows. The new system uses R-8 insulated flex duct or sheet metal, new supply boots and grilles, a new supply plenum and return box sealed with mastic, and properly sized return air. Old ductwork — including any that is moldy, rodent-damaged, crushed, or made of deteriorated duct board — is removed and disposed of. The work is finished with airflow measured at every register.

Why Ductwork Replacement Matters in Florida

Attic ductwork in Hillsborough County lives in 130°F heat for months, and flex duct installed in the 1990s and 2000s is often past its life: the inner liner tears, the insulation compresses, the joints separate, and the system leaks 20–30% of its air into the attic. Many homes were also built with ductwork that was never sized correctly — one undersized return, long runs that starve the far bedrooms — which no amount of AC repair will fix. When a system is replaced with a new high-efficiency unit and put on the old ducts, the new equipment cannot deliver its rated performance. Replacement is what makes the rest of the system work.

How Nolan Air Handles Ductwork Replacement

We start with an inspection and static pressure test to confirm replacement is warranted — sometimes sealing and a few repairs are enough, and we will say so. When replacement is the right call, the quote is based on a duct design, not a per-foot guess, and it is delivered in writing. Work is scheduled to minimize time without air conditioning, usually one to two days. Ductwork replacement in Keystone is commonly paired with a system replacement or attic insulation upgrade; we coordinate the sequence so insulation goes in after the ducts.

Ductwork Replacement FAQs — Keystone

How do I know if my ductwork in Keystone needs replacing rather than repair?

Widespread leaks, crushed or torn flex, visible mold, ductwork over 20 years old, or a layout that starves certain rooms are replacement signs. An inspection with static pressure and airflow readings confirms it.

How much does ductwork replacement cost?

It depends on the number of runs, attic access, return design, and whether plenums are replaced. We quote after an inspection and design.

How long does it take?

Most single-system homes in Hillsborough County are completed in one to two days.

Should I replace ductwork before or after attic insulation?

Before. Ductwork goes in first so it can be sealed and supported properly; insulation is installed over and around it afterward.
