Estimate only. Assumes cooling accounts for roughly 45% of your electric bill during heavy-use months and that savings scale with the ratio between old and new SEER. 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.
Depends on your utility, equipment and system size. We handle the paperwork on qualifying installs.
Your electric utility is where the cooling money is in Illinois. As of March 1, 2026 ComEd incentives are tiered by heating capacity (tonnage) rather than a flat amount.
Amounts tiered by system tonnage since March 1, 2026. · Program details
Northwest Indiana homeowners get the most straightforward cooling rebates of these programs, with published flat amounts by equipment type.
Program runs January 1 through November 30, 2026. Equipment must be installed by November 30, not just applied for. · Program details
Like Nicor, these are gas utilities, so there is no rebate on the air conditioner itself. They matter for the smart thermostat and for anyone replacing the furnace at the same time.
Home Energy Rebate program, 2026. Confirm current amounts and deadlines before quoting. · Program details
Nicor is a gas utility, so there is no rebate on the air conditioner itself. It matters here for the smart thermostat and for anyone replacing the furnace at the same time.
Install between January 1 and December 31, 2026. Apply within 90 days of installation or by January 31, 2027, whichever comes first. · Program details
The federal 25C Energy Efficient Home Improvement Credit, which offered up to $2,000 on qualifying heat pumps, 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.
Most of the Illinois gas-side money sits on the heating equipment, not the AC. If your furnace is the same age as your air conditioner, replacing both at once stacks the Nicor Gas furnace rebate on top of your electric utility's cooling rebate, and it's one install instead of two.

Since 1968, King has installed Carrier air conditioners, heat pumps and ductless mini-splits across Chicagoland and Northwest Indiana. Most homes here have ductwork, which makes central air the usual starting point. It isn't the only option.
An outdoor condenser paired with your furnace, cooling through your existing ducts.
Cool in summer and heat in milder months. Often paired with a gas furnace for deep cold.
No ducts needed. Great for additions, finished attics, condos and homes without central air.
Installed by a 13-time Carrier President's Award–winning dealer.
As air conditioners age, they lose efficiency and break down more often.
Not sure? Start with a diagnosis. Our AC repair techs will tell you honestly whether a repair or a new system 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, air leakage and sun exposure, to calculate exactly how much cooling your home needs.
With the BTU number in hand we show you the efficiency tiers 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, 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, glass type and which direction it faces, ceiling height, air leakage, shading and sun exposure, and the design temperatures for this part of Chicagoland. The output is a BTU-per-hour load, and that number is what sets the tonnage.
An oversized air conditioner is the most common mistake in this trade, and it costs you twice. It drops the air temperature fast, then shuts off before it has pulled the humidity out, leaving the house cold and clammy while short-cycling wears out the compressor. An undersized one runs flat out and never quite catches up. Getting the load right is also the honest answer to "what will this cost?" — tonnage drives the number, so the price comes after the calculation, not before it.
