What Ductwork Repair, Sealing & Replacement Includes

Nolan Air repairs, seals, modifies, and replaces residential ductwork. Ductwork repair covers reconnecting collapsed or disconnected flex duct, replacing crushed or torn runs, resealing joints and boots with mastic, repairing or replacing the supply plenum and return box, and adding or relocating supply vents and return air grilles. Duct sealing addresses leaks at joints, boots, and the air handler connection so conditioned air reaches the rooms instead of the attic. Full replacement is for ductwork that is undersized, badly designed, moldy, or too deteriorated to repair — we design the new layout for the home's actual room loads, not just copy the old runs.

Why Ductwork Matters in Florida

Most Hillsborough County homes have ductwork in the attic, where summer temperatures exceed 130°F. Every leak on the supply side dumps cooled air into that attic; every leak on the return side pulls 130° air, dust, and humidity into the system. Leaky ducts are the most common reason a correctly sized air conditioner still cannot cool the house, why one bedroom is always hot, and why the air handler sweats or grows mold. Studies of Florida homes routinely find 20–30% of conditioned air lost to duct leakage. Sealing and repair are among the highest-return improvements a Florida homeowner can make, and they are required to get full value from a new AC system.

How Nolan Air Handles Ductwork

We start with an inspection: airflow measured at each vent, a visual check of every accessible run, and static pressure at the air handler. That tells us whether the fix is a few reconnections and sealing or a redesign. Repairs use R-8 insulated flex duct and mastic, not tape. Replacements include a duct design sized to the equipment, new boots and grilles, and sealed connections at the air handler. Ductwork work is quoted from the inspection, in writing, before any work begins.

Ductwork Repair, Sealing & Replacement FAQs — Seminole Heights

How do I know if my ductwork in Seminole Heights is leaking?

Rooms that never cool, dusty air, high humidity indoors with the AC running, a sweating air handler, or a high power bill with a newer AC are the usual signs. An inspection confirms it.

What does ductwork replacement cost?

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

Can you add a vent or a return to a room?

Yes. Adding supply vents and return grilles is a common repair, especially for additions, converted garages, and bonus rooms.

Should I replace ductwork when I replace my AC?

If the ducts are leaking, undersized, or over 20 years old, yes — a new system on bad ducts will never perform as rated.
