HVAC Ductwork, Air Handling & Mechanical Products calculator
Ductwork and AHU Quote Price Calculator
A ductwork or air handling quote price starts with the direct cost per section or unit, which includes sheet metal material, fabrication labor, fittings, hardware, and sealant. Applying an overhead and margin factor covers shop overhead, project risk, and the profit margin needed to make the job worthwhile. Fixed project costs such as engineering, shop drawings, submittals, and project management are added on top. The total gives the number to submit on the bid form, and dividing by unit count gives the per-unit price you can benchmark against similar jobs or competitive bids.
What this calculator does
- Build a total quote price for a ductwork fabrication, air handling unit supply, or mechanical product contract. Combine unit count, material and labor cost per unit, an overhead and margin rate, and fixed project cost to get total quoted price and per-unit sell price.
- Use this when preparing a bid for a ductwork fabrication and installation contract, an air handler supply contract, or a mechanical room package. Enter the number of units or sections in scope, your cost per unit including material and labor, an overhead and margin percentage, and fixed project costs such as engineering, submittals, and project management. The result is your quoted total price and the sell price per unit that you can check against competitive targets.
- Turns duct sections, fittings, or ahu units in scope, direct cost per unit (material plus labor), overhead and margin factor into a weighted cost for quote price in hvac ductwork, air handling and mechanical products.
Formula used
- Variable quoted cost = units × direct cost per unit × overhead and margin factor
- Total quoted price = variable cost + fixed project costs
- Per-unit sell price = total quoted price ÷ number of units
Inputs explained
- Duct sections, fittings, or AHU units in scope: undefined
- Direct cost per unit (material plus labor): undefined
- Overhead and margin factor: undefined
- Fixed project costs (engineering, submittals, PM): undefined
How to use the result
- Use it when quote price in hvac ductwork, air handling and mechanical products is being scored for capture or weighted cost.
- Risk-adjustments and discount rates are not in the formula; layer them on top for capital reviews.
Common questions
- What problem does this quote price calculator solve? Build a total quote price for a ductwork fabrication, air handling unit supply, or mechanical product contract. Combine unit count, material and labor cost per unit, an overhead and margin rate, and fixed project cost to get total quoted price and per-unit sell price. You get a weighted cost you can defend before quoting, scheduling, or sign-off.
- Which inputs change the weighted cost the most? duct sections, fittings, or ahu units in scope, direct cost per unit (material plus labor), overhead and margin factor usually move the weighted cost most. Pull from measured hvac ductwork, air handling and mechanical products runs, supplier data, and recent quotes rather than memory.
- How should I use the result? Use the weighted cost in the hvac ductwork, air handling and mechanical products business case or quote build-up.
- What should I verify first? Confirm the capture factor is honest; over-stated capture is the most common reason these models miss.
