Evanston price range against the U.S. range, with the climate and housing numbers behind it.

Evanston Weather and HVAC Load

Evanston logs 6,365 heating degree days and 805 cooling degree days in a normal year, based on the closest NOAA weather station. Heating is the bigger job here, and furnaces and heat pumps in Evanston put in far more hours than the air conditioner. Count on roughly 128 nights below 32°F and 17 afternoons past 90°F in a typical year. Snowfall averages about 34 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 65,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Evanston Housing Stock

The median Evanston home dates to 1952, according to the Census ACS. That makes the typical house about 74 years old. Houses that old often still have duct runs sized for an old coal or oil furnace and 60- or 100-amp electrical panels. Both can add cost when new equipment goes in. About 18,000 households here own their home, 55.8% of the occupied total. The median home value is $472,300, and median household income is $95,766. We use both figures to adjust labor and pricing for this page.

Cook County had 27 hail days and 75 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 2.75 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Cook County also had 8 tornado days in that period.

When Replacement Makes Sense

  • A repair quote runs past a third of the cost of a new unit
  • A tech found a cracked heat exchanger, or the CO detector has gone off
  • Some rooms stay cold, the burner short-cycles, or the ignitor keeps failing
  • The furnace is 15 to 20 years old or more

What Moves the Price

  • Condition of the existing ductwork and any changes it needs
  • Single-stage, two-stage or modulating gas valve
  • Permit and inspection fees, which the local building department sets
  • BTU size, which should come from a Manual J load calculation
  • AFUE rating: a basic 80% unit vs. a 96% condensing furnace
  • New PVC venting if you move to a condensing model

We raised the national figures about 35% for Evanston using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.

What the Quote Should Cover

  • The permit and the manufacturer warranty registration
  • Combustion and safety tests
  • Gas line and vent connections
  • The new furnace, filter rack and thermostat wiring
  • Removing and hauling away the old furnace

Illinois Permits, Efficiency Rules and Rebates

Illinois falls in the DOE's North region. New split central air conditioners must meet at least 13.4 SEER2, and heat pumps sold anywhere in the U.S. need 14.3 SEER2 and 7.5 HSPF2. Expect the contractor to pull a mechanical permit for a replacement job in Evanston. If a bidder suggests skipping it, move on. Also ask for a Illinois license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.

Before You Hire

  • Make sure all three quotes are for the same AFUE and staging, or you can't compare them.
  • Ask for the Manual J load calculation in writing. Oversized furnaces are the most common mistake we see.
  • Look up utility rebates on 95%+ AFUE units before you buy.

Furnace Replacement Questions from Evanston Homeowners

How much is furnace replacement in Evanston?

Plan on $4,300 to $10,500, with most jobs near $7,700. Equipment efficiency, house size and the condition of the ducts and wiring decide where your quote falls.

When is the best time to schedule furnace replacement in Evanston?

Between late spring and early fall. Evanston averages 128 freezing nights a year, and heating calls spike from November through February.

Is a high-efficiency furnace worth it?

In cold climates, a 95%+ AFUE furnace usually earns back the price difference in lower gas bills. Where winters are mild, the payback can take a very long time.

How long does a furnace replacement take?

A straight swap is usually done in one day, somewhere between 4 and 10 hours. Moving to a condensing furnace with new PVC venting can add a few more.
