How Much Does Each Part of Ductwork installation Cost?

The cost to install ductwork in Louisville ranges from $1,820 to $7,290, with most homeowners paying around $3,650. Your actual cost depends on several factors specific to your home and the Louisville market.

🔌
Linear Feet Of Duct

Ductwork is priced per linear foot including fittings — more duct runs to more rooms means proportionally higher costs.

Material (Sheet Metal, Flex, Fiberglass)

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.

📏
Number Of Vents

Each supply and return vent needs a boot, register, and connection to the trunk line, adding $75–$200 per vent.

🔧
Attic Vs Crawlspace

Accessible attics and crawlspaces make duct installation much easier. Tight spaces or inaccessible areas increase labor significantly.

🏗️
Insulation Requirements

Ducts in unconditioned spaces (attics, crawlspaces) must be insulated to prevent energy loss — insulated duct or wrap adds $2–$5 per linear foot.

The South generally offers lower labor costs, though fast-growing metro areas are seeing rates climb. Year-round building seasons mean more consistent pricing and availability.
