Furnace Replacement in Kansas City
Gas furnaces from $4,000 installed, full systems from $9,000, put in by our own licensed crew and never subbed out. Free in-home quote, flat written number before anything is ordered, 0% financing up to 18 months.
Do You Actually Need a New One?
We would rather fix your furnace than sell you one you did not need. Our repair prices are published, so you can do this arithmetic yourself before anyone knocks on your door.
Worth repairing
- The failed part is on the flat-rate menu and the number is small. A flame sensor clean is $125, a replacement is $175, an igniter is $250.
- The furnace has been reliable up to now and this is the first real repair.
- It is comfortably under 15 years old. Most gas furnaces run 15 to 20, so a young unit has plenty of winters left in it.
- It heats the house evenly once it runs, and your gas bill has not been climbing winter over winter.
- You are not already saving for a replacement anyway.
Worth replacing
- The repair is climbing toward four figures. A draft inducer motor starts at $600, a blower motor at $775, a gas valve at $800, and they rarely arrive alone.
- This is the second or third repair in the same stretch of winters.
- It is past 15 years old. Most gas furnaces run 15 to 20, so you are spending on borrowed time rather than on a system with a warranty behind it.
- Rooms will not hold temperature and the bills keep going up for the same thermostat setting.
- Our crew finds a cracked heat exchanger, which is a safety problem and not something to patch.
When it is a close call we quote both, put them side by side, and leave the decision with you. See the full flat-rate repair menu →

Oxbox, Backed by Trane
Oxbox is a Trane brand, built by the same engineering team and held to Trane's approval standards. What it skips is the premium badge markup, which is exactly why we install it: equipment that lasts, at a number a Kansas City family can actually say yes to. The warranty is automatic, with no registration window to miss.

Frequently Asked
How much does a new furnace cost in Kansas City?
Gas furnace installs start at $4,000 and high-efficiency models at $5,500. A full AC and furnace system together starts at $9,000, or $10,500 high-efficiency. Heat pumps start at $9,500. Those are starting points for a standard install. The exact number comes after a free in-home visit where we measure the space and size the system, and you get it in writing before anything is ordered.
How long does a furnace last?
Most gas furnaces run 15 to 20 years. Past about 15, replacement starts belonging in the conversation, not because the furnace will quit on a schedule but because you are deciding how much more to put into it. A well maintained furnace reaches the top of that range and a neglected one does not, which is most of what an annual tune-up is buying you. If you do not know how old yours is, there is a date on the label inside the burner door and our crew will read it off for you.
Should I repair my furnace or replace it?
Run the arithmetic before you decide. Our repair prices are published, so look up what your repair actually costs: a flame sensor is $125 to clean or $175 to replace, an igniter is $250, a draft inducer motor starts at $600, a blower motor at $775, a gas valve at $800. If it is a small part on a furnace that has otherwise been reliable, fix it. When the repair starts climbing toward four figures on a unit that has already needed work, that money is better spent on a system that comes with a warranty. We will quote both and let you decide.
Do you offer financing on a new furnace?
Yes. 0% financing up to 18 months, so a new system does not have to wait for a perfect month. We go through the options during the free in-home quote.
What brand of furnace do you install?
Oxbox, which is Trane's value line. It is built by the same engineering team and held to Trane's approval standards, without the premium badge markup. Gas furnaces carry a 1-5-10 limited warranty plus a 20-year limited warranty on the heat exchanger, with no registration required.
Who does the install, and how long does it take?
Our own licensed crew, every time. Duct Daddy is a licensed mechanical contractor and we never sub out installs. One crew handles the ductwork, the equipment and the startup, so there is one company to call afterward. We protect your floors, haul the old unit away, and leave you with photos, the warranty certificate and your paperwork in one place.
Is it worth waiting until the furnace actually dies?
It is your call, but a furnace that quits usually quits on the coldest night of the year, and that is the worst time to be making a large decision quickly. Replacing on your own schedule means a free in-home quote, time to look at the financing, and a crew booked when it suits you rather than whenever the next opening is during a cold snap.
