Cost to Ductwork Installation in Hartford, CT (2026)

If you’re budgeting a ductwork installation in Hartford, most projects run $2,242-$8,968, 12% above the $3,800 national average. What moves that number most is usually one thing: Duct Material: Flex vs. Sheet Metal vs. Fiberglass. On its own it can swing the cost by $3 - $20 per linear foot, so that’s the decision to slow down on before you sweat the smaller stuff.

Easiest place to save: Before replacing ducts, have a duct leakage test done ($150-$300) - if your system leaks less than 10% of total flow, sealing may be sufficient instead of replacement, saving thousands.

In the Northeast (where Hartford sits): HVAC labor rates run $100-$150/hour in major northeastern markets. Older homes with plaster walls and complex layouts add significant time. Many utilities offer duct sealing rebates that offset some of the cost.
