Quick answer

Leaky, crushed or undersized ducts are a leading cause of hot rooms and high energy bills. Ducts in Texas attics lose significant cooling when they leak. Duct sealing, repair of disconnected runs and replacement of old flex duct restore airflow and help your AC cool more efficiently.

Ductwork Repair & Sealing you can count on

If one bedroom is always hot or the airflow from some vents is barely noticeable, the problem may not be your air conditioner at all. It may be the ductwork in your attic.

We inspect your ducts, measure airflow and repair disconnected, crushed or leaking runs. For older homes, a full duct replacement with properly sized, insulated duct can transform comfort and efficiency.

Answers

Ductwork Repair & Sealing FAQs

How do I know if my ducts are leaking?

Hot rooms, dust, high bills and visible gaps or disconnected ducts in the attic are signs. A duct inspection confirms it.

How long does ductwork last?

Flexible duct typically lasts 15 to 25 years before it sags, tears or loses insulation.

Will new ductwork lower my bills?

Sealed, properly sized ducts deliver more of your AC's cooling to living spaces, which can reduce run time and energy use.

Do you clean ducts?

We focus on repair, sealing and replacement, which solve airflow and efficiency problems at the source.
