Notes
- Where the number comes from. The national price for a ductwork replacement is $35 per linear feet of duct — residential duct replacement pricing published for 2026, $22–$58 per linear foot installed. Labor is about 65% of that. Heating, Air Conditioning, and Refrigeration Mechanics and Installers near Ann Arbor, MI average $74,760 a year against a U.S. mean of $64,780 — a factor of 1.154 — so the labor half is scaled by that and the material half is not.

- Why the city matters, not just the state. Trade pay moves inside a state as much as it does between states. Crews do not commute across a state to bid a job, and materials ship at national prices either way — so a metro wage is the honest input here and a state average quietly rounds four different cities into one number.
- Design temperatures. 89°F summer and 1°F winter at Detroit Metropolitan — the two numbers a Manual J starts from, and the reason equipment sized for one city is wrong in another.
- What is in the price: trunk and branch duct, fittings, hangers, mastic sealing, registers and grilles, and labor.
- What is not: the air handler or furnace, a new return path where none exists, asbestos abatement on old duct wrap, and any drywall work. These are the lines that turn a $5,776 quote into a $7,220 invoice, so ask about each one before signing.
- Use this as a bid check, not a quote. It prices an average job in average condition. Difficult access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a per-unit average.

$5,776 is the typical number, and three bids on the same scope normally land between $3,630 and $9,571.

Why the city changes the number
About 65% of this job is labor — $3,754 of the $5,776 above. Labor is the only part that moves locally; a bundle of material costs what it costs wherever it is nailed down.
Heating, Air Conditioning, and Refrigeration Mechanics and Installers near Ann Arbor average $74,760 a year, against a U.S. mean of $64,780. That is a factor of 1.154, so the labor half is scaled by it and the material half is not.

The lines that turn a quote into an invoice
Ask about each of them before you sign. On a job this size they are the difference between $5,776 and something a quarter higher.
Use it as a bid check, not a quote
This prices an average job in average condition. Access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a national average.
If a bid lands outside $3,630 – $9,571, that is not automatically wrong — but it is the question worth asking out loud.
