The cost to install ductwork in Minneapolis ranges from $2,110 to $8,460, with most homeowners paying around $4,230. Your actual cost depends on several factors specific to your home and the Minneapolis-St. Paul market.
Ductwork is priced per linear foot including fittings — more duct runs to more rooms means proportionally higher costs.
Sheet metal ducts last longest and flow air best but cost the most. Flex duct is cheaper but can restrict airflow if not installed properly.
Each supply and return vent needs a boot, register, and connection to the trunk line, adding $75–$200 per vent.
Accessible attics and crawlspaces make duct installation much easier. Tight spaces or inaccessible areas increase labor significantly.
Ducts in unconditioned spaces (attics, crawlspaces) must be insulated to prevent energy loss — insulated duct or wrap adds $2–$5 per linear foot.
The Midwest has a strong pool of skilled tradespeople, and labor rates tend to be moderate compared to coastal cities. Union and non-union shops both compete, giving homeowners options on pricing.

Most ductwork installation projects in Minneapolis take 2–5 days to complete. The timeline depends on project scope, contractor availability in the Minneapolis-St. Paul metro area, and seasonal demand. Scheduling during Minneapolis's off-peak season (typically fall and winter) can reduce wait times and may lower costs.
Metal ductwork lasts 20–25 years or longer if maintained. Flexible ductwork typically lasts 10–15 years before degrading. Signs of failing ductwork include uneven temperatures between rooms, dusty air, high energy bills, and visible damage or disconnection.
If your ducts are over 15 years old, leaky, poorly insulated, or improperly sized, replacing them with your new HVAC system maximizes efficiency. Leaky ducts waste 20–30% of conditioned air. At minimum, have ducts professionally sealed and tested.
