Chicago, Illinois: HVAC Replacement Cost Calculator

Replacing an HVAC system in Chicago typically runs $3,500 to $7,000 for a gas furnace, $4,000 to $7,500 for central air conditioning, and $7,500 to $13,000 when you replace both at once. Heat pumps land between $6,000 and $12,000 installed, while a ductless mini split ranges from $3,500 to $10,000. Chicago labor runs about 20% above the national baseline, with local HVAC technicians earning around $37.29 an hour, so labor is a meaningful share of every quote.

Worked example

Take a 1,600-square-foot bungalow on the Northwest Side with a 22-year-old gas furnace and a matching outdoor AC unit that has started leaking refrigerant. Because both pieces are at end of life and the ductwork is already in place, the homeowner replaces them together as a matched system, which usually lands in the middle of the $7,500 to $13,000 range — roughly $9,500 to $10,500 for a mid-efficiency furnace and a standard-efficiency condenser. Pushing toward the $13,000 end typically means a high-efficiency condensing furnace, new venting, or electrical and duct modifications; staying near $7,500 usually means a straightforward swap with no structural changes.

Frequently asked questions

Why does HVAC replacement cost more in Chicago than in other cities?

Chicago's labor index sits at 1.20, meaning installation labor runs about 20% above the national baseline, and local HVAC technicians earn roughly $37.29 per hour. Since a furnace or full-system install can take a crew most of a day or longer, that wage difference shows up directly in your quote.

Is a heat pump a good choice for Chicago's climate?

Chicago sits in climate zone 5, where winters are cold enough that heat pump sizing and backup heat matter a lot. Heat pumps run $6,000 to $12,000 installed here, which is higher than a gas furnace at $3,500 to $7,000, so ask contractors how the system will perform on the coldest days and what supplemental heat is included.

Should I replace my furnace and AC at the same time?

If both units are near the end of their life, replacing them together costs $7,500 to $13,000 — less than paying separately for a $3,500 to $7,000 furnace and a $4,000 to $7,500 AC in different years. You also avoid paying twice for the same labor visit, which matters in a high-labor market like Chicago.

What does a ductless mini split cost in Chicago?

Ductless mini splits run $3,500 to $10,000 installed in Chicago, with the low end covering a single-zone unit and the high end covering multi-zone setups. They're a common option for Chicago two-flats, attic conversions, and additions where extending existing ductwork isn't practical.
