Mobile Home Ductwork Repair & Replacement in Kansas City

Section Repair

One crushed joint, one disconnected run, one wet section — cut out and reconnected. The right call when damage is isolated and the rest of the duct run is sound.

Full Replacement

Duct crushed in multiple spots, original to an older home, or been sitting wet for a while. Patching section by section usually costs more in the long run than replacing the whole run at once.

Why does mobile home ductwork fail more than site-built homes?

Underbelly ductwork sits fully exposed under the home, held up against the subfloor. When the belly board sags or tears and insulation falls, the flex duct beneath it takes the weight, gets crushed, pulls apart at the joints, or sits in standing moisture. In a site-built home the ducts are usually protected inside a basement or attic — a mobile home has none of that protection.

How do I know if my ductwork needs repair?

Common signs: rooms that never get warm or cool no matter the thermostat setting, a noticeable temperature difference room to room, higher-than-normal energy bills, or a musty smell coming from vents (often means moisture is sitting in torn duct sections).

Can you repair just a section, or does it all need replacing?

It depends on the damage. A single crushed or disconnected section can often be cut out and repaired. If the duct has been sitting wet, crushed in multiple spots, or is original to an older home, full replacement is usually more cost-effective than patching section by section.

How much does mobile home ductwork replacement cost in Kansas City?

Full underbelly ductwork replacement typically runs $2,000–$6,000 depending on home length and duct configuration, or roughly $35–$55 per linear foot. Section repairs are priced individually and are usually far less. Since the underbelly needs to be open either way, we quote ductwork work alongside belly board and insulation repair whenever possible — it avoids paying for access twice.

Do you replace ductwork on its own, without belly repair?

Yes, if the belly board itself is still in good shape and only the duct underneath has failed. Most of the time, though, duct damage and belly damage happen together, so we assess both during the free inspection.

Will new ductwork actually lower my energy bills?

Yes — a crushed, disconnected, or wet duct run is one of the most direct causes of high heating and cooling bills in a manufactured home, since conditioned air is leaking out before it ever reaches the vent. Sealed, properly supported duct fixes that directly.
