Quick answer: A furnace replacement in the Kansas City area typically costs $4,000 to $6,500 for a standard 80% efficiency gas furnace, $5,000 to $7,500 for a 96% high-efficiency furnace, and $7,000 to $9,500 for a variable-speed furnace at 97% efficiency or higher. Those prices include the equipment, removal of the old unit, and professional installation. Replacing your furnace and air conditioner together usually runs $7,000 to $14,000.
Replacing a furnace is a big decision, and most homeowners only make it two or three times in their lives. At JOCO Heating and Cooling, we believe you should know what a fair price looks like before anyone walks into your home. This guide covers what Kansas City homeowners pay in 2026, what moves the price up or down, when repair makes more sense than replacement, and what rebates and tax credits still apply this year.
Furnace Replacement Cost in Kansas City (2026)
| Furnace type | Efficiency (AFUE) | Typical installed cost in KC | Best for |
|---|---|---|---|
| Standard single-stage | 80% | $4,000 to $6,500 | Budget replacements, homes with existing metal flue venting |
| High-efficiency two-stage | 96% | $5,000 to $7,500 | Most Johnson County homes; lower gas bills through long Kansas winters |
| Variable-speed modulating | 97% and up | $7,000 to $9,500 | Larger homes, comfort-focused owners, quieter and more even heat |
| Furnace + AC together | Varies | $7,000 to $14,000 | Systems where both units are 15+ years old |
For context, Angi’s 2026 data puts the average new furnace in Kansas City at about $4,205, with most homeowners paying between $2,424 and $6,167, and the national average at about $4,814. Lower-end figures usually reflect a basic unit with no venting or ductwork changes. Your exact price depends on your home, which is why we always quote in person.
What Affects the Cost of a New Furnace
1. Home size and furnace capacity
Furnaces are sized in BTUs. A larger home needs a larger furnace, and larger units cost more. Sizing should come from a load calculation, not a guess or a copy of what was installed before. An oversized furnace short-cycles, wears out faster, and leaves rooms uneven. An undersized one runs constantly on the coldest January nights.
2. Efficiency rating (AFUE)
AFUE tells you how much of your gas becomes heat. An 80% furnace sends about 20 cents of every heating dollar up the flue. A 96% furnace loses about 4 cents. High-efficiency furnaces cost more up front but save on monthly gas bills, and the savings add up faster in a Kansas winter than in a mild climate.
3. Venting and installation changes
Moving from an 80% furnace to a 90%+ furnace usually means new PVC venting and a condensate drain, because high-efficiency furnaces vent differently. Older homes may also need ductwork repairs, a new gas line connection, or electrical updates. These are the most common reasons two quotes for the “same” furnace look very different.
4. Permits, removal, and extras
A proper replacement includes permits where required, haul-away of your old furnace, a new filter base, and startup testing. A new thermostat, air cleaner, or humidifier adds to the total but can be worth it. Ask every contractor exactly what their price includes.
5. Brand and warranty
Brand matters less than installation quality, but warranty terms vary. We install Rheem, Lennox, and Mitsubishi equipment. Learn more on our Brands We Work With page.
Should You Repair or Replace Your Furnace?
Replacement usually makes sense when one or more of these are true:
- Your furnace is 15 to 20 years old or older.
- A repair would cost more than half the price of a new furnace.
- Your technician finds a cracked heat exchanger, which is a carbon monoxide safety issue.
- Your gas bills keep rising while your home stays less comfortable.
- You’ve needed multiple repair calls in the last two winters.
If your furnace is younger and the repair is minor, repair is often the right call, and we’ll tell you so. If your air conditioner is also aging, read Should I Replace My AC Unit and Furnace at the Same Time?
Rebates, Tax Credits, and Financing in 2026
The federal furnace tax credit has ended
The federal Energy Efficient Home Improvement Credit (Section 25C), which covered up to $600 on qualifying high-efficiency gas furnaces, ended for equipment installed after December 31, 2025. If you see older articles promising a federal furnace tax credit, that information is out of date. Ask a tax professional about your specific situation.
Utility rebates
Evergy offers heating and cooling rebates in its Kansas territories for qualifying high-efficiency equipment installed in 2026, mainly heat pumps and air conditioners. Rebates are first-come, first-served and must be submitted by a participating contractor. If you’re considering a heat pump instead of, or alongside, a furnace, ask us whether your system qualifies. See our heat pump services.
Financing
A new furnace rarely shows up on schedule. We offer financing options so you can replace an unsafe or failing furnace now and pay over time. Ask about current terms when you request your free quote.
How to Save on a Furnace Replacement
- Replace before it fails. Planned replacements in early fall avoid emergency pricing and mid-winter wait times.
- Get the size right. A properly sized furnace costs less to buy and less to run.
- Compare apples to apples. Make sure every quote covers the same efficiency, venting, permits, and haul-away.
- Keep up with maintenance. An annual tune-up protects your warranty and your investment. See our HVAC maintenance plans.

Frequently Asked Questions
How much does a new furnace cost in Kansas City?
Most Kansas City homeowners pay $4,000 to $6,500 for a standard 80% furnace, $5,000 to $7,500 for a 96% high-efficiency furnace, and $7,000 to $9,500 for a variable-speed furnace, installed.
How long does a furnace replacement take?
Most furnace replacements are completed in one day. Jobs that need new venting or ductwork changes can take longer.
How long does a furnace last?
A well-maintained gas furnace typically lasts 15 to 20 years. Annual maintenance helps it reach the upper end of that range.
Is a high-efficiency furnace worth it in Kansas?
For most Johnson County homes, yes. Kansas winters are long enough that a 96% furnace usually pays back much of its higher price through lower gas bills over its lifetime.
Is there a tax credit for a new furnace in 2026?
No. The federal 25C tax credit for gas furnaces ended for equipment installed after December 31, 2025. Some utility rebates still apply to heat pumps and qualifying high-efficiency equipment.
