The request

What the homeowner needed

Old flex duct that has torn, sagged or lost insulation leaks conditioned air into the attic and restricts airflow to the rooms. Cleaning does not fix that, so the runs were replaced.

Work performed

  1. 01Remove the old duct. Disconnect the old flex runs in the attic and carry them out of the house for disposal.
  2. 02Install new insulated duct. Run new insulated flex duct and connect it to the plenum and the room boots.
  3. 03Seal and check. Seal the connections and check the new runs for kinks and proper support before closing up.

A closer look at the job

What we found

The photos show the attic's existing flex duct runs and supply plenum before the work, the old duct removed and laid out outside the house for disposal, the new insulated duct material on site, and the new flex runs connected to the supply plenum in the attic.

How we approached it

Replacing duct starts with getting the old material out cleanly. The old flex runs were disconnected in the attic and carried out of the house for disposal, keeping the mess out of the living space. New insulated flex duct was then run to the room boots and connected to the supply plenum. The connections were sealed and the new runs were checked for kinks, sharp bends and proper support before the attic was closed up.

Signs to watch for

  • Some rooms much warmer or weaker airflow than others
  • Torn, flattened or sagging duct visible in the attic
  • Insulation missing from sections of the duct
  • Rising energy bills without a change in how you use the system
  • Duct that is original to an older home

Why it matters

Attic ducts in Texas sit in one of the hottest parts of the house. When flex duct is torn, crushed, sagging or has lost its insulation, conditioned air leaks into the attic and the air that reaches the rooms is warmer and weaker. Cleaning does not repair damaged duct. When the ductwork itself has failed, replacing the runs restores airflow and keeps the cooled air inside the system.

Outcome

How it finished

The old duct was removed from the attic and replaced with new insulated runs, connected and sealed at the plenum.

Questions

About this kind of job

Straight answers to the questions we hear most about this kind of work.

How do I know if my ducts need replacing rather than cleaning?

Cleaning deals with dust and debris. If the duct is torn, crushed, disconnected or has lost its insulation, cleaning will not fix it and replacement is the better option. An inspection will show which one you need.

Do you remove the old duct?

Yes. The old duct is taken out of the attic and away from the property as part of the job.

Is new flex duct insulated?

Yes. We install insulated flex duct, which matters for ducts in a hot attic.

Can only some of the ducts be replaced?

Yes. If only certain runs are damaged, the replacement can be limited to those sections.
