Air duct replacement and repair

Leaking, crushed or disconnected ducts waste the air you paid to condition and carry attic dust into your rooms.

Air Duct Replacement and Repair

Air that is breathed by you and your family circulates through the entire air duct system of your home, which demonstrates the importance of having clean and functioning ducts. The dirtier and more dysfunctional your air ducts are, the dirtier and lower the quality of the air in your home will be.

A leaking duct is a hole in your budget

If your duct system is damaged or contains leaks, your home's energy use and your energy bill increase exponentially and proportionately. When the system is compromised it requires significantly more energy to keep your home at a comfortable temperature, which can amount to thousands of dollars wasted on electric bills.

Worse, the air escaping from supply ducts has to be replaced by air pulled in somewhere else — usually through the attic, the crawl space or the wall cavities, along with everything living in them.

What we actually find up there

Flex duct crushed under stored boxes or stepped on during another trade's work. Runs that came apart at the collar and now dump conditioned air straight into the attic. Sagging duct with standing kinks that choke airflow to the farthest room in the house.

Tape that dried out and released, insulation sleeves torn open, and registers connected to nothing at all. None of it is visible from inside the house, which is exactly why it goes on for years.

Repair or replace, and how we decide

A single failed connection on an otherwise sound system is a repair. A system where the liner is degraded, the runs are undersized or the material has absorbed rodent contamination is a replacement, because sealing dirty duct just seals the dirt inside.

These are only a small handful of reasons to consider calling Attic Heroes for your air duct needs. We value your family's respiratory health and the energy efficiency of your home, and our staff has over a cumulative decade of expertise in air duct replacement and repair.

Signs you need this

When it is worth calling us

  • A smell from the vents when the system first kicks on

Frequent questions

Frequent questions

No. Cleaning removes what is inside intact duct. If the duct itself is torn, crushed or has absorbed contamination, cleaning it does not restore it. We tell you which one your system needs and why.

Very often, yes — a crushed or disconnected run to that room is the single most common cause. We confirm it with airflow at the register before and after, so the answer is measured rather than assumed.

Yes. We handle duct work in commercial and industrial spaces as part of our interior build-out services as well as on its own.
