Why AI Can't Price Duct Work
Duct work hides under floors and in humid Appalachian crawlspaces — exactly where AI cannot look without a technician in a headlamp. Crushed flex on damp soil, failed hangers, and leaky returns pulling musty air set the real price for Laurel County homes. Leo Jones & Son prices duct repair and sheet metal after inspection, not from a per-foot national average that assumed a clean basement.

What does an AI price mean for duct work?
Duct pricing depends on access height, material type, linear footage replaced versus sealed, return relocation, and whether supplies collapsed onto wet ground in a Kentucky crawl. Online per-foot averages ignore low-clearance belly crawls, asbestos-era tape, mobile-home belly ducts, and cathedral ceilings that need new supply paths. Sealing alone versus full replacement are different budgets AI treats as interchangeable. Duct pricing also depends on whether returns must move out of a musty crawl, how much sheet metal versus flex is involved, and if mobile-home belly ducts need HUD-aware connectors.
When should you use an online estimator?
Suspect ducts when rooms are uneven, bills climb with short cycles, supply air smells musty, or a new AC never delivers promised comfort. Use humidity and short-cycling Learning Center guides to prepare questions. If the issue is one sunroom only, mini-splits may compete — we route honestly instead of selling duct work you do not need.
Why do online quotes fail for this work?
Cloth-tape fixes sold as permanent in 90-percent humidity crawlspaces. Pricing a new outdoor unit while leaving under-house ducts dumping air into dirt. AI quotes with no crawlspace photo, no access note, and no static-pressure context. Encapsulation sold as HVAC when another trade should lead. Ignoring return paths that pull air from a musty crawl before any IAQ gadget install. Crushed flex on damp crawlspace soil, failed hangers, and leaky returns under Laurel County houses set duct prices—not a per-foot national chart. AI quotes without access photos invent precision while the real failure is under the floor.
What proof should you expect before trusting the number?
We inspect, support, seal, and replace failed runs across London, Manchester, and Corbin routes — and say when encapsulation belongs with another trade before a high-efficiency upgrade. Crawlspace Duct Repair niche page documents humidity-specific failure modes we see every season. Duct proposals distinguish sealing, support, and full replacement with photos from the crawl when boards ask why scope changed.
What should you do next?
Request a duct assessment via /ductwork-sheet-metal or /crawlspace-duct-repair, or call (606) 864-6105. Note which rooms are worst, whether the crawlspace is accessible, and if prior contractors only taped the problem.

Frequently asked questions about why AI can't price ductwork in London and Laurel County
Can AI price duct replacement from a floor plan?
Plans miss crawlspace height, moisture damage, and hanger failure under the house. Our technicians inspect access and flex condition before quoting sealing versus full replacement — AI per-foot averages assumed a clean basement you do not have.
Why is crawlspace duct work expensive?
Low-clearance belly crawls, wet soil contact, rusted hangers, and full run replacement take skilled labor in humid Kentucky conditions. Cloth-tape jobs fail within a season — we price durable supports and mastic so the fix survives the next July.
Should I replace the AC before fixing ducts?
Often ducts first, or together in one scope. A new high-efficiency outdoor unit on crushed flex wastes money and short-cycles. We sequence honestly from our London shop — sometimes a duct fix defers replacement years.
Is sealing the same as replacement?
No. Some runs can be sealed, supported, and insulated; others are too crushed or mold-stained to save. Diagnosis under the house decides — AI sealing calculators cannot see damp soil contact from a laptop.
Can duct work be quoted from satellite photos?
No — crawlspace height, moisture, and hanger failure are invisible from above. Inspection drives scope; AI map tools cannot replace a technician under the house.
