Estimate only. Assumes heating accounts for roughly 70% of your winter gas bill and that savings scale with the ratio between old and new AFUE. Your actual result depends on ductwork, insulation, sizing and thermostat habits.
Rebate programs change every year and most have install deadlines, not application deadlines. Here's what applies in our service area right now.

Nicor Gas is where the furnace money is in Illinois. The biggest rebate comes from pairing a high-efficiency furnace with a smart thermostat.

ComEd has no rebate on a gas furnace. It matters if you pair the furnace with a heat pump (a dual-fuel system) or add a smart thermostat.

The federal 25C Energy Efficient Home Improvement Credit, which covered qualifying high-efficiency furnaces, expired December 31, 2025 under the One Big Beautiful Bill Act. Equipment installed in 2026 does not qualify, even if it was purchased in 2025. Utility rebates are now the main source of savings. If your system was placed in service on or before December 31, 2025, ask your tax preparer about claiming it on your 2025 return.
If your air conditioner is the same age as your furnace, replacing both at once stacks your electric utility's cooling rebate on top of the gas furnace rebate, and it's one install instead of two.

Since 1968, King has installed Carrier gas and electric furnaces, boilers and heat pumps across Chicagoland and Northwest Indiana. We'll recommend the system that fits your home, your comfort and your energy-savings goals.
Energy-efficient, high-performing Carrier gas furnaces, the go-to for Chicago winters.
Efficient electric furnaces that deliver steady comfort in any home.
New boilers and radiant heating systems for homes that rely on radiators or in-floor heat.
Two-in-one systems that cool in summer and heat in the cooler months.
Not every problem means replacement. These three signs usually mean a new system will cost less over time than keeping the old one going.
Not sure? Have one of our technicians inspect your furnace first. You'll get an honest recommendation on whether repair or replacement makes more sense.
Call or use the form. We set a time for a King Comfort Consultant to come out, usually within a couple of days.
Your consultant works through the house room by room, accounting for insulation, window area and orientation, ceiling height and air leakage, to calculate exactly how much heat your home needs on the coldest days.
With the BTU number in hand we show you the furnaces that fit your home, what each one runs per month, and the utility rebates you qualify for.
Written estimate with the equipment, labor, permits and warranty spelled out, plus financing options available with approved credit. No surprises on install day.
NATE and Carrier-certified techs handle removal, install, venting, startup and cleanup. We also file your rebate paperwork.
If you're not satisfied with the work or the service, call the office and we'll come back and make it right.
Manual J is the residential load calculation standard published by the Air Conditioning Contractors of America, and it is the accepted way to size heating and cooling equipment. Rather than working off square footage, your consultant goes room by room: insulation levels, window area and glass type, ceiling height, air leakage, and the winter design temperatures for this part of Chicagoland. The output is a BTU-per-hour heat loss, and that number sets the size of the furnace.
An oversized furnace heats the house in short bursts, shuts off, and starts again, which means uneven rooms, more wear on the parts, and higher bills. An undersized one runs nonstop on the coldest nights and still falls behind. Getting the load right is also the honest answer to "what will this cost?" — size drives the number, so the price comes after the calculation, not before it.
