Cost depends on scheme (supply, exhaust or both), airflow, duct runs and sizes, AHU type and site access. Quotes without a survey almost always rise after inspection.
A typical package: engineer visit, design or layout, duct fabrication, install, silencers, controls, balancing and test reports. High-rise work, night shifts, demolition and custom fittings are extras.
Office AHU systems with standard sections cost less than industrial exhaust with local hoods and filtration. Restaurant kitchens add grease capture and makeup air.
Saving on ducts and balancing creates noise, dead zones and high fan power later. Proper air-change calc and tight in-house ducts beat ceiling rework next season.
Confirm balancing reports, service hatches, silencers and fittings are in the quote — bare “duct install” usually grows on site.
Occupied-building night work often moves the price more than mid-range AHU brand differences.
Compare warranty, in-house duct shop and who services the system — not only the line total.
Restaurants and plants need grease ducts or filtration as their own line items.
