What Replacement Looks Like Here
Kansas City is three different install jobs depending on the block. The brick bungalows in Brookside and Waldo have stood since before the war and usually need the ductwork looked at as closely as the equipment.
Mid-century ranches across the Northland are the classic changeout. Downtown lofts carved out of old warehouses have ductwork that has been patched and rerouted more than once, which changes how a system gets sized. We quote the house in front of us.
We would rather fix your furnace than sell you one you do not need, which is why our repair prices sit on the site next to our install prices. See the flat-rate repair menu → or read the full repair-or-replace breakdown →
New System Pricing
Starting points for a standard install in Kansas City, MO. Every install is quoted free, in person, after we see the space and size the system to your home. In Kansas City the quote depends heavily on the block, because a pre-war bungalow in Brookside and a Northland ranch are not the same install even at the same square footage.
| System | Installed, starting at |
|---|---|
| Gas furnace | $4,000 high-efficiency $5,500 |
| Full AC and furnace system | $9,000 high-efficiency $10,500 |
| Air conditioner | $5,800 high-efficiency $6,500 |
| Heat pump | $9,500 high-efficiency $10,500 |
| Air handler | $3,300 for all-electric and heat-pump homes |
| Mitsubishi mini-split, single zone | $4,000 for additions, garages, rooms the ductwork never reached |

Frequently Asked
How much does a new furnace cost in Kansas City, MO?
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, and heat pumps start at $9,500. Those are starting points for a standard install. The exact number for your Kansas City home 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.
Do you install air conditioners in Kansas City, MO too?
Yes. AC installs start at $5,800, or $6,500 high-efficiency, and a full AC and furnace system together starts at $9,000. Doing both at once is usually cheaper than two separate visits a few years apart, and it means the furnace, condenser and coil are matched and started up as one system. We also install heat pumps, air handlers and Mitsubishi mini-splits across Jackson County.
Should I repair my furnace or replace it?
Run the arithmetic first. 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 climbs toward four figures on a unit that has already needed work, that money is better spent on a system with a warranty behind it. We quote both and leave the decision with you.
Do you offer financing?
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, along with the optional Comfort Shield parts and labor coverage at $499 to $1,299.
Who actually does the install?
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 for your exact model, and your paperwork in one place.
