Furnace Replacement in Northbrook, Illinois
Furnace Replacement in Northbrook typically costs $4,500-$9,000 installed in 2026, depending on home size and efficiency tier.
Northbrook is furnace territory. The village is largely 1960s-through-80s construction, so most homes run forced-air furnaces and central air that are now on their second system and reaching replacement age together. A right-sized high-efficiency furnace is one of the highest-return upgrades a Northbrook homeowner can make.

Furnace Replacement for Northbrook homes
The furnaces we replace across Northbrook's subdivisions - Mission Hills, Sunset Ridge, and the many neighborhoods built in the boom decades - are typically 80% AFUE units matched to ductwork that has held up well. Because these homes were often built with the furnace slightly oversized, we don't simply repeat the old capacity; a Manual J load calculation usually points to a smaller, better-matched unit that cycles longer and heats more evenly across the house.
Northbrook homes are also good candidates for dual-fuel setups, where a high-efficiency furnace pairs with a heat pump so the system leans electric in mild weather and gas in deep cold - a configuration that stacks utility incentives, adding ComEd's heat-pump rebate on top of Nicor's furnace rebate. Whether you go standard or dual-fuel, the install crew sizes to spec, runs venting and condensate to code, removes the old furnace, and registers the new warranty before the day is out, with the current rebate amounts confirmed in your written estimate.
