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 in South Dakota average $61,100 a year against a U.S. mean of $64,780 — a factor of 0.943 — so the labor half is scaled by that and the material half is not.
- 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 $5,056 quote into a $6,320 invoice, so ask about each one before signing.
- Why state matters more than people expect. Materials ship at national prices; crews do not move. South Dakota sits below the national mean by 5.7%, which lands on 65% of the job and moves the total by $194.
- Use this as a bid check, not a quote. It prices an average job in an 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.
Replacing 150 linear feet of duct in South Dakota
$5,056 is the typical figure, and bids on the same scope normally land between $3,178 and $8,379.
That is 150 linear feet of duct at $34 each.
Why this is not the national number
The same job priced at the U.S. average comes to $5,250 — this one is $194 less.
The reason is one number, and it is a published one. Heating, Air Conditioning, and Refrigeration Mechanics and Installers in South Dakota average $61,100 a year against a U.S. mean of $64,780, from the Bureau of Labor Statistics OEWS release for May 2025, SOC 49-9021. That is roughly $29 an hour of trade pay, a factor of 0.943, or −5.7% against the national mean.
Labor is about 65% of this job. Material is the other 35%, and a box of fittings costs the same in every state it is opened in. So only the labor half is scaled here, and the material half is left at national pricing.
That is the whole model, and it is deliberately simple enough to check: $3,286 of labor, $1,770 of material.
Measuring the run
A typical single-story house carries 150 to 250 linear feet of supply and return duct once every branch is counted, and a two-story with a second zone can pass 350. Count the trunk, every branch to a register, and the returns — the returns are the half people forget, and they are also the half most often undersized in the first place.
Where the price actually goes
Flexible duct in an open attic is the cheap case and sits near $3,178. Sheet metal trunk, sealed and hung in a tight crawlspace, sits near $8,379 — the material costs more and the hours cost far more, because the constraint is a body in a space that will not accept one.
Do the load calculation first
Replacing duct to the same layout that failed is the most expensive way to keep a comfort problem. If a room was never right, the duct serving it was probably sized for a system that no longer exists. A Manual J and Manual D before the tear-out costs a few hundred dollars against a $5,056 job, and it is the only way to know that the new duct is right rather than merely new.
How to use this against a real bid
Three quotes on identical scope should cluster. One well under $3,178 usually means something was left out of the scope rather than found cheaper — read the exclusions before reading the total. One well over $8,379 is either a harder job than average or a crew that does not want the work and priced accordingly.
The figure above prices an average job in average condition. Access, the age of what is being replaced, the season, and how booked the crew is all move it.
